Keep us posted Mike....btw...what does the winner get??
:D

Hey Cessna.....what number does that 36 run?

His 36 went around 85 with the 28's and 7 lbs of boost ,this isn't ceating its here for everyone to see . he did have a very hard time until he got the 28's and the boat is very weight sensitive
at speed ,if he has 4 people in it it slows way down (5 m.p.h. )
I guess this is due to the hull ,but jeff loves his 36 ,tons of room and still fairly fast for a tank

Thanks, I have been trying to figure out what it would tkae to go 90 gps in a 33 Outlaw. My guess is about 700 per side.

It's not cheating...matter of public record now!!:D :D

What hp were the 509's?
 

Does he have stock parts (heads - cams)? I'm sure Keith picked up another 100 per side with his heads and cams.

Keith is suppose to have around 825 at 5500.

I called and he said last summer it got 785 @7lbs of boost ,he said it has canfield aluim. heads ported and polished witha crower I think he said custom cam .
Jeff loves his 36 and will get on board to p.m. you with some questions I can't answer.
Also this motor is bored to a 509 is his ?
He loves his alround boat it really runs well and is dependable
but he again stressed the 26 or 28 pitch bravo 1 .his came with 24's and went 67 new

Wow, Just read this whole thread, Good luck with the project.
My guess is low 90's ???? "92"

Thanks for the info Cessna. I doubt that an extra .015" on each side of the piston (502 bored .030 over) is gonna help a whole bunch, but every little bit helps.

Sounds like he is getting alot out of those motors, sounds like a great package. I would love to hear from someone who has thrown big power at a 33 Outlaw.....

If your buddies 36 runs 85 on a gps with 785 a side, my prediction of 86.5 with 825hp may get beat by an mph or 2;)

Keith's had 24s also and same speed 67 to 68
 

Keith's is still stock bores.

Kanookstr, thanks for taking the time to read and post. Thanks to all. It's been a fun post.
Tomorrow, Tomorrow

:eureka:

Water test #2
 

Things went a little better but not much. They got the speed up to 81 with the big pulleys but boost was only around 4.5 lbs. The boost should have been around 6.5 to 7.5. Keith told me the pop off valves were letting go at 4.5 lbs. and the fuel was still too fat.
The rpm got up to 5100.
I'm a little lost. On what is going on.
You have to keep reminding yourself that this was only the second water test. Keith is about to go crazy. Not having his boat and a one way 4 hour trip.
The main mechanic's mother is still in the hospital and that is not good for Keith's boat nor is it good for the mechanic. My heart goes out for him.
When I hear more I'll let you all know, Mike.

! more mile per hour and I'm in!!!!!!WOOOOOOOOOOHOOOOOOOOOOOOOOOOOOO!!!:p

Wow..... add 2-3 morelbs and I might get the grand prize, should be right there anyway.

Keep us posted, hope the guys Mom is okay.

If I understand right from my brother Whipple has a valve that is a relife valve on each blower and it opens and closes due to releiving excess boost or something close to that and they sometimes are bad and leak boost ,from what I'm told it seems to stop the boost at about 4.5 lbs when broken by venting ! I 've had several people tell me this .
this is how you can change pulleys and the boost not go up ,,,really the only way possible ,right !
sounds like he's making progress ,sorry about the ecu's mabe their fat due to being set up for 7.5 pound and not making but 4.5 ,This kind of thing takes a long time shipping off ect,and your engine guys are I think at the mercy of others ,((bad place to be for all )) Is your buddy going up to n.c. everytime its tested ,WHY
That would be tough on everyone too,poor guy driving that far
get them to finish then him go up ,,is that not easier ??
just my 7 cents worth

P.S. It should fly with7.5 lbs if its going 80 with 4.5 lbs ,,,what prop did he use ??

Long trips
 

He goes up everytime they water test because of his insurance policy on the boat. He is self employed so that helps. Keith told them to call him anytime they would water test and he would be their.
They are telling him if the ECU's are set up properly it won't matter what boost he has on them. They are saying the ECM's will supply more or less fuel. What ever the motor wants. :rolleyes:
How is this possible if their is no O2 sensor. or is their one.
I'm getting a little lost.
Anybody know how these Whipple's feed the brain when they want more food?:confused:

THEIR RIGHT ?
 

Called a buddy and their right the ECU reads boost density by a map sensor on the motor and changes the fuel flow as needed for boost so the ECU must be right from whipple and sounds like its off ,guess we should not second guess them they must know something ?
Boy I would hate to tune and test with a customer looking over my head ,,,I've never heard of this on motor work this detailed
but thats just me ,I don't know !maybe he just sits on shore ??
maybe this is eight cents worth

that beast (tank ) may run yet ,of course 80 from 67 isn't bad

Please forward your buddy this name and number...Jason Saris @ Performance Marine (518)644-3080.

WHY
 

Why was my answer not right ??

I understand what you are saying
 

about hovering over a mechanic's head. Keith has been straight up with them. He has to drive his boat due to his insurance. He told them he understands about the ups and downs of first time water testing.
I don't blame Keith. He has a good chance to learn his motors and ask questions. They are nice enough to let him do this.

Thanks for the phone #. Keith stays pretty much in tune with this post. I'm sure he will call the #.

It's late for me but I have some news
 

Keith called me today and he ran the boat. He probably got it to 95% fo it's full potenial.

Labbed 30's
5700 r's
88.5 mph

About 18% slip

It was in the mid 80's today temp wise

Keith didn't hold it very long. He easied into the throttles and when he got to 5700 he got out.

He still is a little worried about fuel mixture and didn't want to stay in the throttles too long.

Sorry for the long delay, but it was little problems after little problems and all of this rain.
To be fair I'm not calling a winner until Keith has it fully strung out:D.
I'm sure that will happen this long weekend.

Update on Monday

89.4 was my guess . Good to here the boat is almost dialed in. Good luck hope he breaks into the 90's.

A lot has happen on this story
 

and I can't tell you yet all of it BUT

His motors just came off the dyno and

882 hp with 6 lbs of boost @ 5900
881 lbs of torque @ 4000

The story should be out b4 summer

sorry for leaving you guys hanging

I promise it will be a good story when I can tell ya
