tuning your v6

[ftp-tuning]

ok i have a 07 pontiac g6 gt coupe. where i come from Wausau, Wi there is not love for gm v6 cars specially pushrod motors. i honestly get random adds on facebook just so people can talk trash about my car.

my car has a 3.9 with a f40.
this summer were installing a sequential turbo system
at the moment it just has a mild tune
the car shifts into 5th at 140 and its a 6speed

idk why people hate so much on gm cars. how many cars can do 140 into 5th not alot. my buddies s2k cant even touch that and we 0-60 and q/m almost identacle.

if anyone knows anything about doing twin turbos on gms v6s please post some tips in here or pm me. were doing a full twin turbo set up this summer. everything is a 100% custom due to the fact they don't make them for my car lol, and seeing how were using this as a sponsor car everything is going to be off the wall.

technically, all of the C5 corvettes with 6 speeds do their rated top speed in 5th (near 200MPH)

can't say i know much about sequential turbos though... sounds like a fun project though.

what kind of target boost are you shooting for?

Ooooh sequential turbo's!
I dont know if the setup you are talking about is what im thinking, but it is where one small turbo breathes into a bigger one and the little one is wastegated and bypassed one the biiger one spools up right? Like in the big diesel pickup trucks boosting 60+ on the street.

There's your problem right there.

Seriously though, it really doesn't matter what you drive, someone out there is going to hate on it.

If you're in Wausau and can't do your own tuning, look up these guys in Mosinee. They tuned my friend's supercharged 3400 Alero.

Look at his signature Matt - he is the owner of a business that does tuning.

I don't know where you'd put a second turbo in a G6. A good sized single turbo will do you just as well and not overcomplicate things. With modern turbos their is no need for twins.

Sounds like a fun project though. Good luck with it. Traction is going to be your biggest hurdle....

That's cute and crazy, because;

My Fiero has a 3.9L (stroked to 4.2L) and F40 trans.

Initially I twin turbocharged, thought about reliability and accessibility and single turbocharged. I like it much, much better this way.

If you are the gentleman whom I worked with regarding an estimate for a one piece flywheel ($700) to replace the dualmass stocker disregard, otherwise you'll need to replace the stocker as it will not last long behind a significant power increase and is said to be designed with about 10% reserve above its stock application rating per a SACHS representative.

Sequential turbo setup in a G6, it'll be much easier to mount a small stove under the hood. Take it from someone who has more space for a sequential setup in the engine bay than you do and it's still not enough, DON'T put yourself through this. You can find the threads covering my madness to sanity check on this forum.

If you're going to turn it into a race car fine, but a daily driver with all of the stock options, at some point you'll need counseling.

Good luck whatever you decide.

25 track 10 street

close what your thinking of is normally called a staged turbo system. one turbo boosts on atmospheric pressure into the second larger turbo which in turn boosts that even more. like 60psi or so.

thank you for the tips lol. honestly the space issues we have already gone over ill give you a inside.
battery and power box relocated to trunk
turbos will actually be installed behind the engine under the car
also car is getting a 4" custom cowl hood made, where a majority of pipes will fill the space for the intake filters,
and charge pipes to reach the throttle body.

the project is getting worked on by me of course lol, then a friend of mine who went wyotech, and last of all my other friend who builds his own race cars and go carts.

the main reason for the build is the fact that it hasn't been done to this car (that we know of) and of how custom and rare it will be. the business is knew and the best way to get our name out there we think is by the most craziest thing we can do with what we have off hand.

yes there in turn lies the problem traction lol. even at low boost on street settings i will have issues. were looking into getting some sponsors set up for some slicks for dot and track. also looking into motor mounts and inserts. the torque already slams too hard i would hate to see what another 1-2 hundred pounds of torque would do to my car.

also the turbos will be mounted down stream behind the engine, there is a significant amount of space back there actually, the only issue is going to be where to get charge pipes that are shapped funny enough to fit back there.

also when i said 140 into fifth i meant that is when i start 5th gear. the car has never been tested past that area to see what top speed would be. idk if you watched the youtube video but the car seems to taper off after 115. the f40 needs alot more hp to get it up to higher speeds, it is very noticeable. the vid was shot before the final street tune was done, it was running very lean at i would say 16:1 there. now its back to about 14 on 10% ethanol.
