CRT motor

[Esox4130]

Is the motor available and is there pricing on it? Have not seen anything since the excitement at the Miami boat show on it.

[90 5.0]

I beleive I remeber Pro Marine will be the first official dealer. Might call them to inquire about prospective timeline to delivery

[Capt.Insane-o]

There was a CRT flyer in my new pro marine catalog.

[Instigator]

There was a CRT flyer in my new pro marine catalog.
Was just going to post that.

I for one am blown away by this project.
That the Caldwells have gotten it to this stage, and then seeing their fliers in w/our Pro Marine catalogs...., I am blown away.
They have to have a bazillion dollars and a yrs time invested to this point, and probably near zero income to show for it, yet.

Definitely not for the shade tree crowd but will be interesting to see what their clientele brings to the surface once established.

Way cool.

[Capt.Insane-o]

I can't wait. :)

[Instigator]

I can't wait. :)
I would think with current technology that's a 350 - 400 hp, 9,000 rpm motor?

Get the tune right and know the block and case are no longer a weak link??

One of my genius OMC buddies saw it at the Miami show and was blown away.

[Capt.Insane-o]

The 2.5 yeah.. The 3.3 3.5 4.0 really have my interest piqued. I'd love a 4 liter set up for 89 octane for my HST.

[Instigator]

Forgot about that stuff.

And replaceable inserts to change porting ��
Genius!

Cod easily see these become spec motors for Champ and F-1 etc.

[Esox4130]

So basically still the same answer for the past year. no release date and no price lol

[Flightplan]

Can someone please post up this sales flyer?

[JPEROG]

Is anyone running one now? I am curious to know if any of the drag guys are campaigning any on the back of a boat or if they are still being refined at this point. One thing for sure is that this is a massive undertaking that seems to be done with all of the best processes and procedures. I can't imagine the hurdles that they have had to deal with both financially and engineering wise to get to this point. I truly hope that the market will afford to buy them when the time comes.

Joe

[caldwellrace]

Thanks for the interest and support guys. Pro Marine will give the release dates soon . The SR 2.5 has been were most of the testing is focused . This motor will be in the 250 to 350 HP ranges . We have been running drag boats hard and have purchased 2 BaBa boats from Italy (F1 and F2) that are in transit . This will help finalize the SR for release . As for the higher horsepower motors , testing will run into the summer . We will release new vids of the BaBa's running at 100% duty cycle mid to end of May.

We are looking for a good late model #4 and #6 case if anyone has any sitting around

[whipper]

Is this the pro marine were I could buy the CRT engine? http://www.promarineusaboats.com

[BarryStrawn]

Should be at http://parts.promarineusa.com someday.

[Capt.Insane-o]

lol good luck with that. it'd be easier for you guys to cut your own.

[RichS]

New #4's should still be available. ($$$)

[Capt.Insane-o]

List Price
$11868.22

[Michael J Giesler]

Thanks for keeping the sport going Crt as for the price of the #4 gearcase cost is cost but real price is 60% of that list on a sportmaster 2.5 is almost $7000 real price $3700

so whats new with CRT this year? that intake looks interesting...

[Bodhi]

Looks like alot of new carbon fiber

[mistah_max]

anyone know how they made it s 2.7? i know alex heldin (the dentist) did it years ago by using omc pistons. just curious

[noli]

.


I believe they started from the ground up in this design and the process starts out from a billet aluminum piece to make the block


They also have a 3.5L near completion

[noli]

[ seconds ago from Mathew, CRT ]



"The new CRT 2.7 motor has a new rod , crank, piston and port design . All CRT design .

The 3.5 /4.0
motors utilize the same technology.

Twin 3.5's are near complete for the new 32 Doug Wright .

Plans to run the 2.7's first then run the big blocks "

[Hot Shot Merc]

So whats the price tag for that complete motor pictured?

[Da Bull]

Man i love that horn.

[noli]

for pricing I would call Mathew, he's a great guy to talk to. If you're at the show please visit their booth (Could be ProMarine's booth, not sure)

This is a high performance racing after market parts with custom applications for your needs

they can sell you just the drop-on powerhead, or any build level to suit your needs in 2.5L or 2.7L platforms

because this is a custom after market racing product, I would tell them specifically what you're looking for even if you're just shopping around

[pappa pete]

My God! How hard is it for pro marine to price out a complete CRT powerhead! Shouldn't be no secret now but it is, all this hush hush is pissing everybody off

[noli]

.


Pappa Pete,


I'm not calling you out or anything like that so please don't take this the wrong way.

I just got off the phone with Pro Marine and in less than 5 mins I got a price for the 2.5L 450HP power head. I'm not too keen on their terminology, but Julian said "short block"...whatever that means. So I priced out a CRT short block with my specs. Yours will be different as per your own specs. and so I can't list the price here in the forum.

Mercury's 2.5L 280 was my sample host for the CRT powerhead. This really doesn't need divine intervention, if you want 450 HP "short block" which is 2x the power of the 280, I'd say please call ProMarine today.


note: I am not an employee of CRT nor am I a principal. I post lots of things here for the benefit of our readers, so please don't think of me as being biased or have special connections with DougWright, Skater, Predator, CRT, Pilini Marine, etc.

Just asking but why can't(Or is it would prefer not to would understand) you post price with your specs I know plenty of people are curious..
I'm really curious but know damn well I'm not buying them anytime soon so dont want to waste someone's time pricing it..
And I know it's just one spec price and how many different setups there could be

[Capt.Insane-o]

Meh, people would bitch if they cost a hundred dollars.

[CUDA]

So they have a 2.5 and a 2.7 ?

[mrichartz]

Meh, people would bitch if they cost a hundred dollars.

It's amazing how people will complain about price of certain things trying to rationalise why it shouldn't cost that much etc..ask them same thing like why should I pay you that much to work ..lol see what they say
I can't see how anyone would think they would have a low price point.
look how much motors that get cranked out in voume cost...i know ths is common sense but

I mean I will say I do it to but it's really stuff about that's not worth as much as they think..lol

These motors are worth $$$ the amount of time work etc..
They can charge what they they want don't have to buy it.

[pappa pete]

So I got off my ass and Just got off the phone with pro marine they dont have any price on the CRT stuff, waiting on call for block that accepts OEM crank, and a short block with CRT crank, so will post prices when they call back,

[ar300johnson]

Let’s remember that 400R’s cost at Jaco’s is high 20’s to low 30’s,
depending on gearcase and DTS.


The wait for a new motor is one year. Horsepower is expensive. I expect that there will lot’s of pissing and moaning regardless of their CRT’s pricing. You need to be glad that motor looks like it be available soon.

Remember, how fast is directly related to cubic dollars.

[aggiestckl]

Shocker.. Its never going to be for sale, and they get pissed off when you complain you cant get a price.

Great engineering, machining, and innovations.. Horrendous marketing

[Michael Dixon]

Shocker.. Its never going to be for sale, and they get pissed off when you complain you cant get a price.

Great engineering, machining, and innovations.. Horrendous marketing
It's for sale right now and the reason for confusion in price is simple...when you and Joe blow up the street order a Yamaha or a mercury or and evinrude you both get the same motor... When you get a CRT it is truly a custom engine with options on cranks, rods, pistons, horn or svs style intake, Many different reed options ..compression options. Can buy one set up for alcohol race gas or pump gas with the correct curves to match. And now even a different ignition option to do away with old school electronics. So if you are serious about actually buying on contact Matthew and decide if you want a base engine or you want one with all the bells and whistles....Again your engine will be custom to your needs if you want it for drag racing or a twin engine cat or it you wanna put in in a sand rail. There has been countless hours of r and d and went thru 8 generations of engines before we decided it was the best that we can produce. Thank you hope this helps. Again if you're serious contact Matthew

[super aggregates]

There was a lot of talk at the boat show about 450hp @11k rpm :eek:. Who's dyno have these been run on? I know its not Dave's or Brendan's :confused:

[Da Bull]

Funny thing about dynos, They don`t tell the whole story. We aren`t racing dynos anyway. I drove a guys 707hp new car and he bragged about the dyno hp but let me tell you, It did not feel like those old LS-6 big blocks in 1970 that only made 450hp and would pin your back side to the seat.

[baja200merk]

The good SAE approved ones will tell the whole story, theres a reason every respectable tuner in the world uses them including Mercury. Even if they are not SAE they still can be used as a tuning tool we have been surprised a few times (good and bad).

Every OEM and major racing team in any motorsport uses dyno’s. They tell the tale. Bobby, you’re falling victim to the age old issue of the older I get the better it was. A new vehicle with 707 hp would run off and hide from an LS6 Chevelle. Actually I bet you’d be amazed at how many new cars would outrun an LS6 in the 1/4

That must mean I`m getting old. Yep, And damn proud of it. I know they use dyno`s as a tool and that's ok. Think about it like this tho, Mercury made a 2.0L champ motor that made 300 advertised HP. Then they made a 2.5L Drag motor that made 300 advertised HP. Are they the same? HELL no. Will the 2.0L run with the Drag, HELL no. I`m just pointing out that dyno`s don`t always tell the whole story.

[powerabout]

Area under the curve explains the accelaration...

[patchesII]

I bet the torque numbers down low are way different and the Drag really makes about 330-340

[baja200merk]

Merc used a dyno to tune and design the 2.0 but it probably was not SAE nor was it up to today’s standards. I know one of the best in the Outboard world found a 12% difference between certified and not which is where most of today’s high claims come from. That’s true in all forms of dynos from diesels to jet skis...

[powerabout]

I bet the torque numbers down low are way different and the Drag really makes about 330-340
for sure the 2.0 f1 engine was only for tunnel boats so high revving screamer

Please keep in mind that this is only a conversion and not ment to be anything negative about the CTR engine. I`m glad they are making them since Mercury stopped and would love to have the big one on my boat but that can`t happen unless my powerball numbers hit lol. You never know.

Real racing has turns. Both left's and right. Bring those things here into some real water "salt" and rip em rally style through the back country.

Seriously I had this idea the first time I saw that street outlaws. It might be watchable again if they did a boat version. Love to see that happen. Good luck.

A 2.7 will carry 50 more pounds than the 2.5 but that holds true for both engines. As long as they’re the same displacement they run at the same weight

Well with the weight at 1200# that will rule out the Ultra light current class Pro-Drag Outlaw boats

[Hot Shot Merc]

Well with the weight at 1200# that will rule out the Ultra light current class Pro-Drag Outlaw boatsGood Point Rich. I would love to see the sub 1000 lb boats running these motors

[Da Bull]

No dog in this fight but if we`re talking about some sort of weight per cubic inch then it`s about time. I like that idea. No guessing just math.

[patchesII]

Weight per inch won’t work. It would heavily favor the 2.5. I’ll give an example, my boat raced pretty consistently at 915 lbs which gives you 6 lbs per cu inch. If you apply that to a V6 OMC at 218 cu in it would weigh 1308 lbs, a 265 cu in V8 would weigh 1590 lbs. The Mercury 2.5 would run away with it. The big inch engines would need to be under 5 lbs per inch

[tcrabtree]

Regarding weight , Someone explain to me why pro mod should be any different from the other spec classes ie lakeracer prostock 1400 mod etc? All these classes have a 2.5 weight penalty @ 5lbs per every cubic inch gained past standard bore.. 2.5 200 carries 100 more lbs than a 2.4 200 etc.. For example ,Ive added additional weight in LR for yrs just for using a .030 over bore so theres No reason a 2.6__ should run at the 2.5 weight. Most of these so called 2.6s are using Stroked cranks , 3.6 pistons

.


I just got off the phone with Pro Marine and in less than 5 mins I got a price for the 2.5L 450HP power head. I'm not too keen on their terminology, but Julian said "short block"...whatever that means. So I priced out a CRT short block with my specs.



Well, then you didn’t get the price for a powerhead. A shortblock is not the same thing as a powerhead.

A shortblock is a complete rotating assembly in a block, but without the cylinder heads.

If you add cylinder heads (which is a bigger deal on a 4-stroke than on a 2-stroke), you get a longblock.

If you add intake, fuel system, and ignition system, you get a powerhead.

If you add adapter plate, mid section, lower unit, cowlings, and a bunch of smaller stuff like exhaust pipe and linkages, you get a complete outboard engine.

[CUDA]

I guess because the 2.5 Merc is just too efficient, other designs need more cubes to even the playing field and the clubs always wanted to be inclusive,

Remember we race Antique outboards, even the 3.2L Merc never added up to the racers expectations, Not sure what CRT is doing besides a new crank design to gain

power/durability because so much has been tried in the past, I understand everything is stronger than the Merc so it's going to be interesting.

I think Erik's post explains it pretty well from a real life perspective. It makes sense (to me) that cubic inch advantage is a scale of diminishing returns. More cubes equal more horsepower but at the cost of more weight on the moving parts …. bigger it gets the more it weighs the less the gains. I have no idea about why .030 oversize pistons would carry more weight in a particular class or the specifics of how they arrived at the weights so not saying it was or is currently fair or unfair. Just trying to say it's definitely not a simple cubic inch / weight equation that many people seem to think.

Going from Outlaw at 1150 lbs to Promod at 1375 lbs has been a humbling experience for me in terms of realizing what a difference weight makes. I used to think giving up 25-50 lbs with my big block was no big deal but there is a point where it starts to hurt and once you get there it just seems to exponentially get worse with more lbs.

[caldwellrace]

When mother Mercury started the 2.0 then 2.4 and stopped at the 2.5 , there was a reason . They saw the power per CC decrease when they went larger . The spread between the bores and the depth of the floor of the block dictated this . The amount of area in the Transfers is the bottle neck for flow . Simply saying going bigger CC in this particular model , is less efficient . Volumetric efficiencies start to decrease in stroke and bore , or when one or the others done alone . You want bottom end on larger bore and stroke , but see fall off on top side from the 2.5 rpm 's so the end result of power may be less because it simply can't breath like the efficient 2.5 . So in reality when weight is put on or taken off a particular block profile VE should be taken into account . The 2.5 100% has the clear advantage when u study it like this . ........ So when we designed the bigger blocks 3.5 , 4.0 , this was taken into consideration about VE . The bottle neck area was the very first thing designed and then all other points of interest were addressed in the block and crank for these to be very efficient motors for pumping and flowing at high RPM's .
Three are in construction as we speak and look forward to assembly on the new ultra light designed big block in couple weeks .

[joebob.racer]

Wow Caldwellrace very informative read. It’s like I was reading straight from the pages of a engineering journal! But as a potential buyer, I don’t need any more education on VE, thermodynamics, heat transfer, or fluid flow. I want results before I spend 40k on a 11,000 rpm tickling time bomb I want to see it run heads up against mother Mercury’s 40 year old technology at the same weight and basic same displacement. I have no desire to make up for sub par porting with masking it with more displacement or nitrous. It does me no good for the racing I would like to do.

[caldwellrace]

Hi mr JoeBOB.racer that hides behind a key board troll . U know where I am! Bring your best 2.5 40 year old and I will put my best 2.5 forty year old and we will see .Then when I gap your ass we can then put the CRT 2.5 on, run your slow ass again ,then half track your troll ass . And by the way bring your check book bro.. I don't need NOS but what CRT motors will do on Alcohol and NOS is were you will never see on a cast block mister Troll . So i challenge you to get a fast boat and come play in the real TV world and run what you brung . That may be a good name on your real boat Mr Troll. But I doubt you will show ......

[joebob.racer]

Well that apparently struck a nerve. And you obviously misunderstood what I was saying or maybe I just didn’t make myself clear. First off I don’t drag race. I never have,so I would be silly to wager any amount of money on this particular style of racing. We spoke two years ago at the boat show in Miami and you spoke a lot about UIM F-1 Racing and your ability to build a superior racing engine for the series under their current rules. I was also under the impression some special teams were going to test some of your products over this winter? Did they get that opportunity? If so what were the results? Has anybody outside of your own R&D run your product under a very strict third party tech guidelines and inspection and if so what were the results. You can call me whatever you would like, troll is fine. I’m not trying to pick on your product or bully your product name. Just some simple question. You may want to try some yoga with some deep meditation. Find your enter peace and zin! It may help you deal with your anger issues.

So how about moving on as a troll you are. Maybe take up some of your own meditation as this is a boating/racing forum! Move on!

[joebob.racer]

Oh no worries, we will move on. We will race long tails on wooden boats in India if we have to. But we will be racing something. Your ability to side step any resemblance of a real answer, to any question reminds me a lot of a United States politician. Good luck moving forward with your future endeavors. I will now go crawl back under my bridge and let you stumps have your fun. I look forward to the day the world of boat racing gets to see the actual results of a reputable race teams with your products.

DUDE, That's already happened. I`m a witness to it. Where you been??? Under that bridge? You must not get internet service under there.

[FMP]

Are any pictures available of the internals, the specs, the chest? Too soon?

[joebob.racer]

Please enlighten all of mere mortals as too what series the Billet engine has run in? Where it placed?What technical inspection process was performed on the engine to prove what the actual displacement of it was? This really is the only information I am seeking. But no one seams to ever actually answer anything on here. So I will not get my hopes up to actually get any type of usefull information now either.

any basic 3.5 engines dynoed yet? numbers please.

I heard these were gonna run in dsra. Has anyone seen these run? How did they do?

[sick_nick]

any updates on the state of Caldwell or Mathew's recovery? hope all is well!

Matt's been very busy


"600hp 3.5 anyone! Yup... it’s alive..."

Ofcourse we are all waiting for the dyno sheet on that one

[John S]

Meh. When's he coming out with the four stroke stuff?:D

Beautiful work. Would love to see that on a twister.

[H2OPERF]

Looks and SOUNDS amazing..

[Bodhi]

Didnt see them at miami this year...I'm assuming due to the accident?

[AZMIDLYF]

3.5 is barking now...

3.5 is barking now...


https://www.facebook.com/HNRRacing/videos/887198231740195/

Sounds like a 2.5 on steroids. You can hear that’s a bigger, badass motor.

[CUDA]

So when will it make a RACE ?

[AZMIDLYF]

Caldwell is selling some parts on their FB page. Crank, pistons, Verdi rods, etc.

[FUJIMO]

...on that video it states the 3.5 is 600 horsepower. its been dyno'd @ 600, or is this just a guess, or?

[CI STV]

Anyone heard anything more about what’s happening with CRT? Have they sold any of these motors yet?

[Da Bull]

It sure sounds throaty. 3.5 would be just right on my Riot. King of sleepers.

[CI STV]

It sure sounds throaty. 3.5 would be just right on my Riot. King of sleepers.

Yeah, no kidding. I would love to have a ~600hp, 10,000 rpm capable lightweight two-stroke motor that fits under the cowl and bolts on to the same mid-section as my 2.5 drag.
So, yeah, I’m really hoping that this truly magnificent project becomes available to the general public at some point. If it does, it will no doubt be a game changer in the ranks of ODBA, DSRA type events for sure.

[FMP]

How about a sub 5000rpm 500+hp two-stroke outboard...

[mragu]

Pardon my ignorance on this topic but can a powerhead like this be used on a boat like a 27' center console with twins? Or are they just for smaller racing boats. I sure would like to have a pair of lightweight 600 HP motors.:eek:
I had 200HP Stock motors and boat runs right at 70 with t-top which is coming off

[mach351]

Just keep holding your breath y’all :leaving:

[Chaz]

How about a sub 5000rpm 500+hp two-stroke outboard...

It's called a Detroit diesel , don't ~ cha know .. ehh

Yeah but no screaming Jimmy , just enough torque TD won't take it down.
The next step forward.
Great sound in those Detroits

[Speed Jr.]

Lots of hype, zero results. Stick to your merc 2.5.

[CI STV]

Yeah, I for one plan to that, for as long as it lasts. But 2.5s (and especially the Drag) are now in very limited supply and I’ve already sunk enough into my Drag motor/STV project to realize that IF this very brave venture by Caldwell ever came to fruition, it would be a hell of godsend for those of us who still want a high strung lightweight two stroke motor that can rev like a blender.

[Captin Hazlewood]

This thread was started almost 4 years ago, people waiting turned blue and passed out years ago. I think Caldwell's sources for unobtainium must have dried up.

[noli]

there are lots of new stuff from Mathew Caldwell


just can't post them right now...but if you get a hold of Mathew, he will tell you directly

[CI STV]

I certainly wasn’t trying to incite any criticism of Caldwell when I questioned whether there were any updates. Because, in my humble opinion, he has done more, and has bravely gone much further than any enthusiast that I can think of in any motorsport, to enhance the sport he obviously loves. The fact that he has produced a working prototype is reason for nothing short of admiration, to say the least. I can only imagine the challenges he has had to overcome, especially that horrific accident. Designing and funding a project like this cannot be easy. So, major kudos to him, even if he takes another several years to sell one of these things.

Probably a good reason hidden in there why he doesn't post much here.

[CUDA]

Who does post here ... the emperor ?

Call Matt ask him WWW and get a full report back;), I have no need in anything but a flywheel was hoping to see the big motor run, heard rumors of stroker cranks?

[Chaz]

FuMPy .. you asked for a two stroke that wouldnt rev , yet make tons of power. I gave you an example ... :rolleyes:

As usual , your response was incoherent , non applicable gibberish. However I'm proud of you .. one sentence containing "Great sound" was better than nothing .. one out of three ... is stellar for you .. :p

[FMP]

Didn't ask anything from your rattlebox

[FUJIMO]

...3.5 performance info. anyone using one real world that can speak?

[HydroSkreamin]

https://youtu.be/xRcUFvbcWCw

[Chaz]

See FuMPy .. you cant have it both ways . Directly responding back to me giving you an example of a low revving / high power two - stroke , with gibberish .. you can expect to hear a further response. If you didnt want to hear from me .. just say thank you .. :p

Could it be , I was too quick in dismissing your psychobabble .. :nonod:

Perhaps you would like to translate this into English and how it relates to many early 1970's GMC "71" series diesel's ... :rolleyes:
