i think with suporting mods we could see 10psi but you cant compare the gnx to the camaro, the gnx was build as a turbo motor our v6 wasnt.

Me too. I got the base boost working again. Seems like MAF location affected A/F ratio. However, when high boost activated, car leaned out quickly. Ugh. Still working...

With the proper build anything is possible.

There are 4th gen V6's running 18+ psi with no problems.

you'll need to swap out more than that i'm afraid. But dulling down the compression ratio to 8.5 :1 or so will be necessary to help get those boost numbers up. I'm just wondering how the motor will respond to lower compression pistons when not under boost. Reading the specs on the motor, it already sucks spend exhaust back into the cylinder to help cool and improve efficiency by detonating any unused fuel from the original compression/ignition stroke.

That said, the car may run very rich with alot of bog when not under boost if you went with lower compression-ration pistons., well ones that are as low as 8.5:1...

Maybe 10.1 : 1 ratio pistons would be enough to get higher boost #'s without changing the engine's normal behavior...

There is a formula to figure out what max compression you can run with an (x) amount of boost/hp.

Z....have you tried any runs with the VBOX yet? I know you haven't had luck getting over the 5 boost mark, but would still love to see what your getting with that.

I agree with rod, i think if you want to run that much boost if i remember correctly, you'd need to drop the compression down from 11.3:1 to like a 9.6:1 so that you can get more boost in there. i had to dig deep in my mem banks for that piece of info lol

Maybe this weekend. I need to find the time and open/flat road. I have been spending free time working on the boost/meth. I have a dyno scheduled for Saturday again, assuming Vince can get the tuning done. I just tried one tonight and no luck. On Saturday, we have a big local event so I'll probably be able to run some 0-60 times once we are done, though it may be at the base boost (4.8 psi).

Good luck we're all counting on you. I'm PMing you.

FWIW, I live in the meth producing capital of the world a.k.a.417. The Ozarks in MO.

Looking forward to the #'s from Z.

It is cool the STS came out. I thought the advertised 500 hp meant 400 to the wheels. I believe ZMadness is at 350 to the wheels. I thought the >2010 v6 was 312 rwhp. With long headers, CAI, and high flow exhaust it would be 340

I saw a dynoed v6 with only long headers bolted get 33 hp

GM is certifying that the v6 is 312 hp, which I thought was rwhp, not crank hp

STS claimed 500 hp at the crank, is that with or without aftermarket boltons. Is that even proven? So having STS would definately put the v6 at over 400 hp, right? If it is at 350, then I think I misunderstood some facts. Someone said something about getting the v6 to over 600hp? I am interested and confused, but more interested. i might not need to trade for a v8 soon for over 600 =)

the meth you are speaking about, is not the street illegal meth. gasoline is it?

wow, that was a little tough to read. lol First, the v6 camaro has 312hp at the crank. Most cars have been putting down 230-250hp to the wheels, all stock, and depending on automatic or manual transmission. So with the STS turbo, we are seeing 350hp to the wheels (~100hp gain). And I believe that was on 5psi of boost. Bump up to 6psi and with the meth kit, should be 400hp or more to the wheels (~500hp at the crank). It would take more work and more money to push 600hp at the crank on this v6. Unless you just did a 100shot of nitrous on top the the turbo.

Actually the methanol is an alcohol used to cool the intake charge to prevent detonation allowing you to run increased boost.

No plans. Still haven't been able to work out the Tune. Now the base boost (5 psi) is running to rich. It may be a MAF issue. I'm working with STS and Trifecta on resolving this issue. I did add the high flow cats over the weekend (Solo). Sounded a little smoother it that makes sense. I already don't have mufflers so its pretty loud. Hopefully we get this worked out soon and I can log some 0-60 mphs.

Has anyone thought of using E85 for fuel? It would cool the charge and I would think be able to run more boost! Check out this link: www.raceone85.com
Where do I go on or how do I put an add on Camaro5 for advertising for the sales and installations of STS turbo systems. Can anyone tell me?

I'd actually thought of it, but my questions come from would the injectors know how much fuel to inject or are they set to flow a set amount. If they are at a set amount I think you would run this engine dangerously lean. On carb set-ups running alcohol the jets have to be increased a large amount over what a normal unleaded fuel. The alcohol has a higher "octane" rating but it produces less energy per equal amount of even 87 octane. That's why when the flex-fuel vehicles run e85 they get quite a bit less gas mileage. The car recognizes the change and injects more fuel.

Z - with the tune, are the issues because you want to run a tune that will compensate for 2 boost levels, one with the meth (higher boost) and one without (stock boost)?

would it be easier to set the tune for normal boost levels like you had it before, then run a complelty seperate stand alone fuel controller with its own pump and a seperate single injector plumbed into the intake to get the added fuel required to run the higer boost. it sounds complicated and expensive, i dont even know if it can be done, i was just wondering if it was a viable option for running higher boost.
with my last car, when others went to a considerably larger turbo, they were adding injectors to the intake piping for more fuel to compensate for the added boost. they had a seperate controller for those injectors (i think they were using the greddy e-manage ultimate).

by the sounds of it, 350 to the wheels is not enough. is it possible to tune it to run 7psi all the time or does it need more fuel at that pressure?


sorry for the confusing post, i am just brain storming.

Good questions and that's why I joined this forum, for the information sharing so thanks for sharing. After discussions with Trifecta and STS, it was determined that it is not a fuel issue. My first thought was the same thing, not enough fuel to keep up with the boost. However, it was discovered by Trifecta that the ECM is not providing the right data based on the airflow read by the MAF so the computer moves into a "safe/limp" mode until the readings come back into range. Both STS and Trifecta believe that the current fuel injectors are capable to flow enough for the boost that I want to run. I was just sent a new tune so I'll be trying it out tonight. Keep your fingers crossed.

As far as 2 tunes, I should only need to run 1 tune. I know that N20 (e.g. Rod1) needed two separate tunes, however since the turbo is really just increasing the airflow, a single tune should be sufficient. At least that's what is expected right now.

I know its been said but Trifecta has been terrific to work with. The data logger has allowed the "mail order tune" process to work really well (actually e-mail). I currently have a Diablo Predator for my LS1 but will be purchasing a tune from Trifecta as I am sure he can tune the ECM much better than I can with the handheld Predator.
