TK 7 info

[Riverratt]

Thinking about running TK7 in my crossflow since it is fresh this year and crossflows are prone to detination. The specs say it will change 87 to 96 and 92-93 to 101-102. Will 101 be too much for my motor and hurt performance? Should I back down to 87 and hope it brings it up to the 96 or would I be wasting my money on my motor?

[Jeff_G]

not sure what TK 7 is, I assume it is an octane booster. I wouldn't bother, most of the claims by those products are bogus at best. Some of the chemical soups are outright dangerous to your short term and long term health. By the time you actually put enough of X chemical in to do any good (raise octane) you are really over doctoring the fuel. This can cause other problems. The best for any of the OMC Xflows is to back the timing down 2* and run good quality regular gas. If you are concerned about octane run premium. Cheaper in the long run.
There is a misconception that just because a motor has higher compression it needs higher octane. There were many motors made to run in the 1970's on regular gas that regularly exceeded 180# of compression in stock form.
What is important on Xflows is the cooling system, the pump has to be pumping the right volumn, the thermostts or restrictors must be operation, as well as the pressure relief valves, and the water restrictors must be in place. If all are not correct the motor will overheat or will not transfer enough heat to the cooling water causing overheating. A good stream of water out of the pee tube isn't enough.
Most detonation is simply bad fuel on the Xflows. In 30 years I have never seen a Xflow detonate on good quality fuel with the timing proper, the right jets and correct cooling. Even running regular grade fuel.
That being said if the oil is a cheap grade and not enough detergents in the fuel they are prone to coking. In my area a number of years ago the Combination of Exxon fuel and Texaco Haveline oil almost guaranteed coking of the pistons. thankfully today the fuel has changed for the better with more detergents.


Just found this;
TK-7 Corporation and its president, Moshe Tal, have agreed to
settle charges that it made false and unsubstantiated advertising
claims concerning the performance characteristics of gasoline
additives sold under the "TK-7" brand name. Under the consent
agreement issued today for public comment, TK-7 would be prohibited
from making such claims for its products in the future without
substantiation.

TK-7 Corp., an Oklahoma-based company, manufactured and sold
various fuel additives under the product name "TK-7" for use in
automobiles, motorcycles, motorboats, golf carts, chain saws, and
snowmobiles. According to the administrative complaint issued by
the Federal Trade Commission, TK-7 advertised that
its products could extend engine life, lower engine operating
temperatures, protect spark plugs from fouling, prevent carbon
build-up, increase engine power, boost octane levels, and increase
gasoline mileage. The complaint alleged that TK-7's claims were
false and unsubstantiated.

.

What engine ran 180psi and regular fuel? Even allowing that regular leaded fuel in the 70's was 92-95 octane and premium was 97-100, I've never seen a 12:1 engine recomending regular.

[RBT]

Wayne Tripp put me onto this stuff, Tony Brucato has run 26cc heads with it and pump gas for 2 years. The stuff is weird.
Like Jeff above, most are BS. This stuff seems to work. I have not got the balls yet to go run 180psi on my 15k powerheads without c-12. But I am working my way there... slowly.
I am this year I am at 165psi and TK, and a friend on here that has never been much for taking things slow is going straight to 26cc on his Daryl Lane drag, with 91 octane and 2 oz of TK-7.

Jeff as far as I know, that info is true, but was proven later that what they claimed was true, somewhere on here and on STVOwners is the results.

Plus I trust Tony and Wayne, the funny thing is I still don't 100% believe it, but I do run it in my sleds, and I swear it runs better....... could be my mind, but I am not the only one to think this way.

RT

[riverrunner114]

I read that article as well where they had to sign a consent agreement with the feds, but that was also in feb 1991. lots can happen in 15 years. I have never used it but if Wayne uses it, I bet he has data. and like the commercial says, "knowing is half the battle" :)

[Trikki1010]

RT is right,

Wayne posted that the govm't sued the manufacturer for false claims, until they tested it and found out it DID perform as requested and is utilized by the military as of this day.

[crazy horse]

I talk to Wayne about this also, I think it was a thread on here a couple of years ago. I haven't ran it in my XS yet but was thinking about it this summer. I have been running it in my vertical cylinder 410 Homelite saws. The parts for these are harder to find than inline parts by far and I heat with wood so I take very good care of them. I have three 410's and one is a NOS powerhead.:) My first one still runs perfect and I've had it for 21 years. I keep a close eye on them and if you loose power you'll know it when your cutting. I've been running tk-7 for a couple of years in the two I use and I haven't seen any drop in power and there's not any scuffing on the chrome and no pinging, I hate that. When Textron made these saws you had to buy the clylinder and piston as a set, They were made with a real close fit and will make alot of power with a little work.

[Wolverine]

Been using it for 3 years in my Drag motor and my sleds. One of the best kept secrets on the market today.

[Bones]

Where can a person buy this stuff? I saw it on Pitstop marine. Are there any parts stores that carry it? I wonder what they mean by "octane effect"? A little hard to believe 1 oz. per six gal. can turn 87 to 96.

[yanny_haulinbass]

it would be good insurance. I always wonder if I am actually getting premium grade when I am fillin the boat. Cab anybody tell me what this magic juice might cost per ounce?

[crazy horse]

Here's one place for TK-7. http://www.ridemor.com/page/page/674358.htm

I just found the bookmark from Pitstop. This is where I bought a gal. http://www.pitstopmarine.com//product_info.php?cPath=13_32&products_id=515&osCsid=b31a84250318e434ff06656d19dba38f

[stvhelm]

Ive been doing it for years but It only works with tall pitch props. It seems the small props let the egt go to high. I never really waited around 1400* too long to find out how long it will last. The motor needs a load to put some fuel through it to keep the temps down. I ran TK 7 occasionally. It helps a little too. I kept it with me for those unfamiliar gas stations.

[Riverratt]

But if I mix it with the 93 I always run will it be too much octane for my motor and hurt performance?

[Jeff_G]

Chris, many of the OMC motors particularly the 40hp and 50hp ran 180#+, still do.
Octane is octane, it is a measurement of resistance to knocking. 86 octane of 1972 is the same octane as 86 is today. 97 of 1975 is the same as 97 today. It is only a measurement. Octane is only one small part of the different measurements used to classify the chemical soup we call gas today. There are many different factors involved in why a motor needs a certain octane. And yes compression is one of them. But that is not to say that just because a motor has high compression you need high octane. Ya just can't make blanket statements like that.
In a particular case if you raise the compression in that motor design through cutting the heads you may have to raise the octane.
Back in the 1970's the inlines for instance ran perfectly well on regular 83-87 octane. Today they tend to detonate even on 100+ octane when pushed hard. So what is the problem? The problem is the design of the motor doesn't work as well with the fuels of today which are all designed and engineered for automobiles and light duty trucks and emissions and fuel economy regulations. The fuel is not designed for outboard use, so problems occur.

As for the additives when is too little and when is too much? Too much octane can hurt as well. I just don't buy the miracle cure in a bottle that is advertised to work with virtually every type of spark motor known. There are many different requirements for a water cooled two stroke vs a low compression, low rpm 4 stroke! That's not to say it doesn't do some of what they advertise. Maybe it does raise the octane, but are their other negative effects as well? Are their harmful chemicals? Cancer causing compounds? I don't know.
Until I see independent test results on the particular motor I am running I am very wary.
I'm not saying don't use the additive, just investigate carefully.

[Tony Brucato]

I wish that you guys wouldn't use TK-7, maybe the price will go back down!:D
Seriously though, I love the stuff, but don't know enough about how or why that it works that I would tell somebody else to trust their own motor with it.

[chris_lacey]

Jeff, yes I understand all of this. 87 is 87, 97 is still 97. What I am saying is that what we used to call regular in the 70's we call very good premium today.

In the 70's I worked in a FINA service station. Our regular was 93-94 octane. Point being, our regular in those days was better than the premium of today. Engines that could run on regular in 1972 could probably not run "todays regular" of 85-87 octane, but would requre "todays premium". And 12:1 engines that required premium (100 octane) back then, would require 100 octane race fuel now, not pump premium.

I agree that compression is not the only factor in determining what octane an engine needs to run to avoid detonation, but an engine that required 94 octane in the 70's to avoid detonation still requires at least 94 octane.

I can't believe that an engine with 180psi cranking would live long on 87 octane regardless of how far you retarded the ignition timing or how rich it was.

[Jeff_G]

In the 70's I worked in a FINA service station. Our regular was 93-94 octane. Point being, our regular in those days was better than the premium of today.

I don't know about how octane is posted at the gas stations in Canada but Regular back in the early 70's regular grade was 81 to 84 octane, with a few stations selling regular in the high 70's octane! There was not any mid range unless you went to Sunoco with their Custom Blend pumps and High Test was in the low to mid 90's range.

When I started racing in the mid 70's I ran 83 octane Regular from a Phillips 66 station. In the late 80's early 90' I had to run Premium 93 octane. Now I have to run race fuel of 100+ octane motor rating.

[Trikki1010]

Didn't we change our ratings to RMH/2 in the late '70's or early '80's ?????

Was that a oil industry scam to reduce octane ratings after the shortage was over ????

[W. Tripp]

There seems to be more than a little misunderstanding about octane. In the US, fuel is rated by an average of the RON (research octane number) and MON (motor octane number) giving the AKI (anti-knock index). One brand of 91 octane may have a higher MON rating than another brand's 93 octane. Two different brands of premium pump gas with the same AKI rating may run completely different in the same engine.

Another BIG issue is how quickly the fuel burns in your engine - the speed of the flame front across the chamber. Many times higher octane fuels burn more slowly than lower octane fuels - BUT NOT ALWAYS. The amount of toluene (methyl benzene) in the fuel helps increase octane AND increase flame speed - just one of many additives in many different fuels.

TK-7 is an additive that changes the way the fuel burns (increasing the AKI) and increases the burn speed of the fuel. The "Super Power Booster" and "Two-stroke Race Gas Formula" also contain a lubricant that reduces wear.

I have been using it for decades in two-strokes, four-strokes, and rotary engines, small displacement and LARGE displacement engines, and both naturally asperated and turbo and supercharged engines. I use it in my lake boats all of the time. I generally notice a 2.5% power gain (and reduced wear) with no other changes. I have found that many engines can run more timing, compression, or more boost and I have seen as much as 12-13% more power made when the engine is optimized for it.

A good example of what TK-7 does to fuel is in new model Corvettes that retard timing in hot and humid weather. When runing 2 oz. of TK-7 in each 5 gallons of pump premium, the ECU will not retard the timing, and if the traction control in turned off, the wheel spin at stoplights is hard to deal with.

In my brother's 38 foot boat with two 500 EFI engines, TK-7 allows the engines' timing to be advanced 4 degrees, acceleration improves and top speed increases 3 mph as the engines can now pull the same prop a few hundred more rpm.

My cycle runs the 1/4 mile between 1 and 1.5 tenths of a second quicker when I add TK-7 to the pump premium I normally run - with no other changes.

I like it, and I have regularly recomended it to others. I don't fully understand how any additive in such a small amount can do what this stuff does, but I have repeatedly proven it to work. But like anything, use it at your own risk - it is your boat.

I don't have anything to gain by anyone buying this stuff, and I get about 5-10 e-mails a month about guys asking questions about it...at this point, I wish I had never mentioned it here, it only helps to make others faster ;)

-The B&D Automotive (www.bndautomotive.com (http://www.bndautomotive.com)) has signed a deal with TAL Technologies (the manufacturer) to be the only distributor for TK-7 products. The other sources for it are buying it from them.

An article (text only) testing TK-7 by David Vizard (a well know engine builder, writer, and performance and racing consultant) is posted on the following thread by the Administrator - http://www.stvowners.com/forum/index.php?showtopic=681&hl=TK-7

Use it, or don't...your choice.

[Riverratt]

Wayne, is it possible that it could hurt performance in my crossflow omc because of too high of octane?

[W. Tripp]

I haven't seen it happen before, but that doesn't mean it couldn't reduce power. The ONLY time I have seen TK-7 make less power, was when added to a HIGHLY oxygenated racing fuel with 120 octane and 12% oxygenate.

Let me give you an example or three:

1.) My motorcycle with the stock fuel and timing maps made best power and torque on 87 octane. When I remapped the fuel and added 3-5 degrees of ignition advance, I got 7 more hp on the dyno - but the engine required premium pump gas to run now. When I added TK-7 to 87 octane, it made a bit over 3 more hp - almost 3% power improvement with no other changes.

I then added TK-7 to 93 octane and did not see any change in performance until 8300 rpm. From 8300-9800 rpm, the engine made almost 2 more hp (at peak) than the TK-7/87 octane fuel - even more was made when the fuel and timing were adjusted to take advantage of the fuel mix.

2.) On my STV I have a couple of powerheads. The one I run most is a stock 280 rotator with 260 electronics, SVS, and custom reed cages and reeds. The heads are STOCK. With 2 oz of TK-7 (Two-stroke formula) in each 5 gallons of 93 octane pump gas, the boat pulls harder and turns a couple of hundred more rpm than in straight pump gas.

If I bump the compression in this engine to 187 with another set of heads, the engine really comes alive.

3.) A friend with a stock 225 merc on a heavily loaded bass rig gets 3-4 mph more (on GPS) when he runs TK-7 than when he runs normal pump premium. He has more octane than he needs, but the engine seems to like it, and pulls harder, and planes off more quickly with the TK-7 than without it.

Your results may be different, but I seriously doubt you will decrease performance...but it is not impossible.

[gearcase]

if you had 5gal of av gas left in the tank and top it off with 15gal 89 octane the only gas they have at the lake is TK- 7 compatable with the av gas?

[Wolverine]

I use the 2-stroke PRGF with great results. Tony uses the Super Power Booster. I was originally told that they were the same blend......just different labels. If there is a difference between the two additives, what is it and is one better suited for 2-strokes.

[MattGreen]

There seems to be signfifcant interest and a lack of knowledge of what exactly is in TK-7. Does anybody have a Material Safety Data Sheet (MSDS) for TK-7 ? I am very curious to know what is in it, and the ingredients should be listed on the MSDS.

Even if the "trade secret" clause is claimed by Tal Technologies on the MSDS, the contents can be identified (and the proportions of the respective consituents) using GC-MS. I have access to instrument time at a reduced price if anybody is interested in coughing up the dough to find out what this stuff is. It would be less than $300 USD (maybe somwhwat less) and I'd need a few mls of TK-7.

I could then also give some health effects information, if anything is known about the ingredients.

A gascomatograph (not sure of the spelling anymore) will only be able to give you certain properties of the chemicals that are in TK-7 by identifying their parameters such as R.I. ( refractive index. It cannot give the exact content nor exactly how much, only approximations. It is very accurate, just not precise.

[MattGreen]

Rob,

A gas chromatograph in tandem with mass spectrometry detection (GC-MS) and the use of chemical libraries and automated searching (a process known as "open characterization") will allow the constituents of virtually any volatile organic compound to be identified. Once they are identified, subsequent "runs" using standards can give quantitative data to the ppb level or below. Although a few factors can "throw a wrench into the works", tweaking the GC parameters and the skill of the instument's operator can overcome most of these obstacles.

You might be confusing other GC setups. You are correct, other GC detectors (such as the more common/cheaper FID or NPD) cannot identify compounds, only quantify them when they are known to be present.

Refractive index relates to other analytical techniques. And "accuracy" and "precision" have formal scientific definitions that I think you are unclear on.

Please don't take offence to the above, I deal with this kind of data for a living. In fact, I should get back to work ! I'm sure our network administrator will block access to this site eventually....!

Matt

[Wolverine]

No offense taken, as it's been fifteen years since I worked in this field. I worked for 5 years in a lab conducting tests on incoming chemicals and outgoing blended product. At that time, it was not entirely possible to positively identify each constituent with the equipment made available to us. Testing equipment has probably advanced since then and my knowledge is probably "old school" by todays standards. I am, however, quite clear on the "accurate and precise" principles. My career has gone a completely different direction and I am no longer involved in the chemical industry.

[TBuck2003]

Ok,

Here is the deal. BND Automotive LLC and their shop is only 5 miles from our facility. We asked them to send a sales person to us to discuss what the story is. The owner's name is Brian, and he came and took 2-3 hours of his time with us to clarify what the story is. They have released the military versions of their fuel catalyst and are in the process of marketing the "upgraded" formulas under the name ACES. This stands for American Clean Energy Systems Inc. Within a few months, all TK-7 products including the TK-7SCF versions will become ACES in name. So the TK-7SCF Super will become ACES IV Gasoline formula. The TK-7SCF Super EFI will be ACES IV-E. TK-7SCF PRGF(professional race gas formula) will become ACES IVP. The TK-7SCF 2-Stroke will become ACES IV-2-S. TK-7SCF Alcohol booster will become ACES IV-A. The TK-7SCF Nitromethane Formula will become ACES IV-N. The TK-7 Diesel Formula is being released as the Military formula also so it is called ACES II. Another product that is also from them is the ACES III Catalyst for oils. The point is that the quality is continuing to go up and the technology that you have either used before, or are thinking of using is just getting better. The lubricant oils that BND Automotive makes will still be available under the present QuantumBlue name, and the total point is that we do have an opportunity to use something that will help with our fuel purchases. Also we were made aware that the sulfur content of the fuels for
both diesel and gasoline are going to be dropped dramatically. Diesel will go from 500 PPM to 15 ppm. Gasoline will go from 130ppm down to 30. For those who don't know what this means, understand that in diesel they are taking out 97% of the lubricant out of their fuels. There goes pumps, injectors and cylinder bores and much more wear. In gasoline, we need sulfur for pumps, injectors, cylinderbores etc. The ACES products have been designed to deal with our new world fuels. We should consider using them and making your own decision on how they will work for you. You can contact Hydromotive with any questions or product reccomendation.

[150aintenuff]

What engine ran 180psi and regular fuel? Even allowing that regular leaded fuel in the 70's was 92-95 octane and premium was 97-100, I've never seen a 12:1 engine recomending regular.
you can get 210 PSI in a 9.4 :1 vortech 87 octane fuel motor so 180 isnt unheard of even today.. as a matter of fact any new production vortech head equiped small block will exceed 200 PSI compression and they are 9.4:1 compression ratio

[stoker2001]

Here is an interesting reply to TK7 mix ratios from a TK7 dealer .

1. If you manually mix your oil and fuel then you would need the two stroke formula.
The recommended starting dose would be 1 ounce TK-7 to every six gallons of fuel/oil mixture.

2. If you have an oil injection/metering system and do not mix your oil and gasoline, then the TK-7SCF EFI formula is what you need. Again the recommended starting dose would be 1 ounce TK-7 to every six gallons of fuel.

If you find you need to make adjustments in the TK-7 to fuel ratio to obtain peak engine performance, do not increase the dosage, reduce the dosage. I know this may not make sense because we all tend to believe more is better. It often is, but not with TK-7.

Years of testing has proven that "over dosing" does not increase performance. I have one racing customer who has achieved significant results using as little as 1/4 ounce TK-7 to 5 gallons of gasoline in his ATV's and dirtbikes. In motocross, he reports having consistantly knocked 2 tenths of a second off his 300 foot time from the start line. One of the fellows racing drag boats has told me his best results were obtained when he mixed 1/2 ounce TK-7SCF Two Stroke per 6 gallons of fuel.

[RideMor]

Hi Stoker - Thanks for passing on the information.

I have received a request to clarify this statement regarding TK-7 and oil injection systems:

2. If you have an oil injection/metering system and do not mix your oil and gasoline, then the TK-7SCF EFI formula is what you need. Again the recommended starting dose would be 1 ounce TK-7 to every six gallons of fuel.

To clarify - The direct oil injection systems that introduce the oil and fuel separately into the engine would use the TK-7SCF EFI.

Systems that blend the oil and fuel before it enters the engine will use the TK-7 Two Stroke formula.

[Wolverine]

I use the 2-stroke PRGF with great results. Tony uses the Super Power Booster. I was originally told that they were the same blend......just different labels. If there is a difference between the two additives, what is it and is one better suited for 2-strokes.
Maybe David (Ridemor) can answer this question for us????

[W. Tripp]

They are not the same. They have the same lubricant additive that the normal RGF does not.

[RideMor]

Hi Rob - The formulas are optimized for each application. For example: The standard 2 stroke formula and the 2 stroke PRGF will both have some common characteristics such as the compounds added to increase lubricity, reduce plug fouling and stabilize the fuel/oil mixture. The differences would be in the ratios and the presence or absence of other chemicals. The diesel formulas employ anti-microbial agents and pour point depressants.

By the way - The PRGF formulas are designed to allow mixtures greater than the 1 oz to 6 gallons of fuel. The recommended maximum doseage as previously discussed was centered around the standard TK-7 gasoline formulas, not any of the specialty formulas.

First, lets keep this discussion centered on the 2-stroke formulas. That's what most of us are interested in. What factors would determine which formula to use? At what point does an engine require more than what the standard 2-stroke formula offers. If I can get the same results using 1oz./6gal. of the standard formula compared to 2oz./5gal. of PRFG, I'm wasting a ton of money at $140/gal. for TK-7 or $165/gal. for the new ACE formula.

[RideMor]

The formulas are optimized for each application. The standard two stroke formula is designed to work in engines having compression ratios up to 11.5:1 and can boost the octane effect up 102 with standard 93 octane pump gasoline. The two stroke PRGF formula is designed for engines with 11.5:1 compression ratios and above. The PRGF can produce octane effects up to 120 octane using standard pump gasolines.

Give Steve a call at Performance Sales/Service he is a member of S&F, and is a dealer for the juice. Chances are he will discount it out to beat the other competitors. 1-815-626-6738 Steve definatly treats us all right.

[Cp]

Has any here tried this? Does it work? Where can I buy some? Seems like a real timely product now. With two road vehicles and a boat that need premium, I'd like to try a gallon or two or maybe.......

[Cp]

bttt! is this bs?

[stokernick]

thread's two years old?

[gfinch]

I use it as insurance. 145 lbs cranking compression in 2 300+ hp OMCeazes. All I can get at the pump is 91 octane with alcohol. I have had no fuel related engine failures. Had a reed plate screw dance with a piston recently, the other pistons looked perfect, no abnormal wear in the bore or crown of the piston that I had seen before I started using TK-7 or now Aces.

[Cp]

Thanks, Gary!!

I was thinking about trying some, but it sounds like they've pretty much doubled the price, so it may not be as attractive... :cool:
