I've got a spare 738cu. with 4 NOS systems that will get that slug moving Call me @BR549

Bob, Based on pictures, it would seem you have plenty of volume. Is that thing on a crank trigger? If it is a XFI on a crank trigger, you can set it up to tune it sequential. You can tune each cylinder individually regardless of the erratic flow. Fatten lean cylinders, lean out rich cylinders. It may not be as much plenum design as tuner limitations. I don't pretend to be able to do it myself, but I have the best FAST tuner in the country available when you get it back together. If you would like to talk to him, and I think you should, let me know and I get you two in contact.

bob,i ran a simialer intake set-up on my 632,i had to tune each cylinder itself,with the fast system,i've been thinking about your post.and i agree with the detenation,luckily i never burned one up on fuel mixture,was always on the nos.what size injectors are in it.

I've got a stiff rod that'll get in your as* and get your bowels moving you west side residing imitator..lol you've got your hands full getting that POS Camaro running..lol

Yes it is on a crank trigger..Yes we can tune each cylinder..The guys at Young's can do that..But my problem with that is air and gas is horsepower. Why would I go to these lengths then tune each cylinder when #1 is getting more air/fuel than #8.. The front cylinders will be making more horsepower than the second row/than the third row than the fourth row..It's a bandaid cure ..It will keep the motor alive but it is not the right way to do it in my opinion. I want equal air and fuel to each cylinder..We will be tuning each cylinder anyway this time. First time shame on them, second time, shame on me. (I'm not referring to Young's in the them) I just don't see an intake with half the volume of the engine being big enough to handle the task in a normally aspirated engine.

I love that. Yeah call John Meaney.

Yeah I know Meaney is "the man" on the computer end of it. He's especially the man on the turbo assisted cars. I guess I'll get in touch with Wilson and get their opinion

Hell if I can screw up a 572 normally aspirated engine, what would I do with that monster?..I'd be like you at Memphis a few years back..burn it down just idling..lol.. call me anything, just don't call me daddy...

.....I guess I'll get in touch with Wilson and get their opinion...

That's an even better idea. I've toured that shop (what they'd let me see anyway). Those guys do things with aluminum that should be classified as wizardry. Carl Foltz is another good choice.

We have similar problems with our little v6 engines. Katech in detroit does a bunch of work evening out the flow to each cylnder

I also agree that these guy's are the best

I bought a 1989 Trans Am turbo V/6 new in 89..Ruggles built 5 engines for it..blew 2 of them up on the dyno..I blew the other 3..it's been parked for 7 years or so..waiting to get him to put it back together..he's been a good friend,,lol..700 h.p. with the original heads is too much for that puppy..ported, pinned etc. He threw away tons of stuff when he shut his shop down..lots of all aluminum Indy stuff..experimental stuff..scrapped a lot of it for aluminum value..

....Once it's secured to the pallet you build a Plywood box around the engine so no one know's what's in there. Don't be afraid to use good wood either. You goal is to protect the engine.

You also want to put a sacrificial corrugated carton on the top of the pallet to prevent the shipping guy's from placing another pallet on top of your skid as crushing it. I can also send you "Do Not Double Stack Labels" to put on the pallet.

Ah a good old PAS Vehicle. If you want copie's of the build documents of your car - shoot me the last 4 digits of your vin and i'll get you copies.

Are you guys running a vacuum pump? pics of intake? how well are the cylinders in question sealing? compression checks? EGT's on exhaust?

You want to sell this one? I know you may need some cash to build another motor, and I have been looking for one of these.

[ProStreet R/T]

A safe starting place is to have the intake manifold volume equal to the CI of the engine.

Can you post pics of the intake manifold? It very well could be a design flaw more than volume issues.

Sequential cylinder tuning is great IF you have a pyrometer in each header tube so you know what each cylinder is doing. W/O that it's totally useless, and in most cases overkill anyway.

Have you measured the plenum volume on your current manifold?

Alan measured it..It was like 320 cu in or so...not near the volume of the engine. We have now put pyrometers in the exhaust headers..Alan has posted pix of the manifold on here somewhere I think. I'll try to get him to do it again...He's covered up right now..

come over at the experience and look at it. Will your big tuckus fit in it?

It is a dry sump engine so they didn't think we needed the vacuum pump. I asked about it when we were doing it and they said it wasn 't necessary with this setup. We had just run the car on the dyno and this was only the 2nd time we'd had it out at the airstrip. We hadn't even checked leakdown or compression yet. Pretty dumb considering we were over 150 hp down from the carb setup. We'll smarten up this time I hope..my pocketbook can't stand another snafu like this..

[coony]

yes, leakdown and compression first, intake manifold theory sounds fishy, I would start looking elsewhere. EGT's should really tell you something

Hi Bob,

Sorry about your difficulties. I gave thought to posting earlier, you know, throw in my two cents, but figured you had things well under control. Also, too much info can be a bit overwhelming.

Anyway, I have been trying to find photos of your intake, but have not been able to track them down. Can you post a photo or a link?

Bob

PS: your buddy still have that Cobra/Whipple set up available? If so, I would like to give him a call.
