exhaust tuner

[HStream1]

So back to the mans original question. IMO sense the Powerhead is off. Remove the adapter plate and take the liner out It will breath better. Dont wasnt your money on a Tuner that will accomplish absolutely nothing for your current motor.

since the powerhead is of and im changing motor mounts, would it be adventagous to throw in a bobs or any other exhaust tuner? computer is comming from bobs and ccm reeds will be installed. 94 200xri

I'm willing to bet that anyone who said :

Don't buy a tuner .. has or had one on their current or past ride ...

Tuner's for me , but not for thee ...

[HStream1]

I dont think its that simple or cut and dry. The man has a bone stock motor. Mercury designed it to perform at its optimum in as manufactured condition. If it was a Highly modified race motor Id say this ABC Tuner will produce the best results because i have the Dyno sheets to back it up.

As Charlie may recall Uncle Bud (BBQ) was doing some extensive Tuner testing several years ago

Two stroke sleds love pipes, makes sense that OB's would too. Its all about heat generated vacuum and eventually choke, where is it and at what RPM does it rear its head? On that note I cant comment with any intelligence whatsoever where these choke points occur on the V6 Mercs, but Im surely paying close attention here...

If your looking for RPM the less BS in the way of the exit door the better

Dont have the Foggiest about Sleds. But on all the Tuner testing I was involved in we didnt see any difference until RPM's were North of 7700. Thats when a HIPO Race Motor really needs to start breathing. Especially one that turns North of 10K. It was extremely interesting because you could actually hear the engine change Tone when the Tuner started working.

Face it. On a Bass Mid the Exhaust has to travel straight down, Hit a Wall and then Turn 90degs to get out. Where Unlike a Race Snout Mid allows the Gasses to escape more freely.

You said "that your done" in post 12 .. but came right back.

Should I go straight to the "liar - liar, pants on fire response ??? No , I showed I could do something you couldn't ... I waited a week before responding ...

I post pictures ... If that's such a bad thing ... Why did you immediately post a pic of an old Brad Anderson three or five .. ??? Do you want to be the pot or the kettle .. ???

The O.P. asked if he should buy a Bob's or someone else's tuner .... I think every little bit helps .. non-stem winder and stem winder alike. So yes OP, free up the exhaust, work on gettin more air in and squeezin it tighter .. and you will see positive results.

For the third time ... I hope it's the charm. I responded to :



​I was taught that I only had to be was ... just a little bit smarter than what I was workin with , and I would be OK ...

Since no one has came back with a >>>> Dude that junk you make won't last 10 minutes ... I understand not everybody has an open mind and won't get my point, but if at least one say's to themselves " I can do that too " Then I would have to say I have achieved my goal.

They say a picture is worth a thousand words .. If someone looks at the pictures I post .. and learns something , then it's just more of the above .

Some people are born knowing ... everything .

I wasn't that lucky , I had to learn what I know by some really great teachers .. over a long period of time. I have never let the nay-sayers, parrots or haters hold me back, and honestly , not gonna start now.

Follow common sense .. but break all the conventional rules along the way ..

ive learned,and want to learn more.
heres where im at:
as with im sure almost everyone here, things have changed a bit since i started this, and lets all remember im in california where gas is crap and 91 is the best at the pump. yes i can get 110 at one pump in town but at $11 a gal its not happening, i fish every week of the year and go thru 15-20gal a trip. SO HEADS WILL NOT BE CUT! but heres the new laundry list,and any realistic opinions are welcomed and appreciated:

rebuilt ff block-complete
all new cdi hp stator/trigger/switchboxes,regulators
bracato acm
ccm reeds/cages lapped to perfection and plate has been smoothed of parting lines and such
bobs exh tuner, which is much bigger than the exhaust plate so will be matching those to each other/liner is out.
injectors all flowed and calibrated
and a whole bunch of pretty **** that will do nothing for performance but make me happy.
not exacty bone stock but not lookin to set the world on fire
new questions:
gettin air out seems to be handled, how do i get more in with a 5 petal cage
is it safe to open exhaust plate as much as will be required ,approx 1/8" around
what else?

new questions:
gettin air out seems to be handled, Well Not Exactly. The FF Block is basically a 225 Promax platform. While it has the opened Exhaust Chest its still has a Choke point and only so much Air can flow. It doesnt matter what Tuner or How Much you Match the Adapter Plates rectangular Exhaust ports to the Bobs Tuner. The Blocks Chest and Exhaust Ports that mate with the Adapter plate are still a Choke Point. Opening the Chest and the Rectangular ports to match produces serious gains if done right. I stress!!! DONE RIGHT!! how do i get more in with a 5 petal cage You dont!!! It is what it is. Youll need a seven Petal front half to make a difference there.
is it safe to open exhaust plate as much as will be required ,approx 1/8" around Yes its safe But you still have the chest issue to deal with.
what else?

There is also one other fault in the laser Injected Plenums. They are Progressive. Meaning It only opens two Butter flys Till about 3/4 Throttle then the other two kick in. A David Driefort Non Progressive Kit Makes a WORLD of Difference!!! It operates all 4 butterfly's simotaniousely vs Progressive.

As far as the Brucato ACU. Well Better make sure its got a proper fuel curve to handle the additional flow or youll be dealing with a Lean condition.

Thats about all Ive got to say on this Thread. Other Than GOOD LUCK!!!

so there will be additional flow,correct?

[rprinzo]

How does one get ahold of said non progressive linkage?

[25two.stroke]

How does one get ahold of said non progressive linkage?

Yes, there would be more flow mid-range which is easy to correct with the ACU if you know how to mess with it. Or maybe Brucato already has a tune dialed for that linkage. You might want to start by contacting Driefort so see if he has that linkage...

[Chaz]

I'm sure someone will say .. Duuuuu we don't use chambers on boats. But for those who care to read will find that the head pipe (block and adapter plate) as well as the divergent cone (first flare) have the most influence as to where the torque peak will occur.
Yes , merc did a great job on producing a good overall package. What's the old saying , "jack of all trades, master of none" . Porting, difference in crankcase volume vs cylinder displacement, ability to move air .... Ohh wait Lake said it plain and simple ..

Uncle Bud , I don't want to say where the dyno proven, magic tuner came from .. tkxyz , might accuse me of "name dropping" ...

now that i think about it, its a bass boat, its always wide open anyway

[HStream1]

Charlie You know I cherish you as a GREAT friend. And I dont mind telling anyone how that magic Tuner came about. It was my design initially. I sent you the Drawing and you fabricated it. You took my drawing to the next level and added some additions that made it even better. It Made 4 more HP over any Tuner tested!!! Its the very reason I applied for the patent!! The Ceramic Coated Oval Drag Tuner running a close second.

I wont post pictures of it at this time. But once i decide Im over Racing perse. Ill make arrangements to start producing them for anyone interested.

#1 Good afternoon Uncle BBQ ..

#2 I was in no way taking credit for the design .. that sentence was leaning towards
"the name dropping" comment ...

#3 I know we went in the think tank a few time's with pictures, templates, tacked tubing, ziz the tack, adjust, re-tack, change the template, till we both liked it.

#4 I think the running joke was ... I missed it by a gasket thickness.

#5 Thank ya brother, for lettin me be part of it ... (insert humble face here)

#6 There is some good and bad news ... Bad news is Mikey signed off on the pattern. The good news is he signed on a spot that got clipped off and went in the garbage can ..

#7 Chaz is a loyal ole porch dog. I been axed about building replica's .. I give them your number ..

[HStream1]

Buddy Its all Good!!! It was a What ever happens project. It turned out to be a Winner!!! As far as Mikey? Well after all he is a Jersey lander and occasionally trans plants to the South SMFH.

Regardless i Love the cantankerous Pain In The Arss!!! But Ill never forgive him for Fornicating one of my Blocks.



And then George Wanting to start Grinding on it!!!
