Twin turbo for the 2010 V6 Camaro

Very true. DIS does make it more difficult. I wonder how much success the Mazda guys have had with their tuning.

What would it cost to twin turbo a 6? If you want to go fast, trade for a V8 model. Add cam and all the bolt ons to the v8 and you're power and money ahead of adding two turboes to a V6. What am I missing? There is a certain amount of "cool" to owning a twin turbo v6. Otherwise, there's no reason to mess with two turboes on a v6. If you want to go fast, add a couple of cylinders.....not a couple of turboes.

Some people prefer turbos to naturally aspirated engines. Jay Leno is one of those people. He intentionally purchased a V6 Camaro and worked with Turbonetics to add twin turbos to it. From what I saw/read Jay Leno did this as a "green" sports car project. He wanted to get good mileage (which you can do with small turbos and staying out of boost) while cruising and still make V8 like power. In the end it amounts to preference and means. A nice single turbo kit for the V6 could go for around $6k-7k depending on what you get. Thats about $1000 cheaper than purchasing the SS model. In the end its personal preference.

Ok you added 54% more air , you gained 54% more HP thats my math .


btw from the turbonetics V8 SS thread , nowhere is a 650 Whp dyno sheet , just we hope to/ it should..
But i did find .
"Updates the first post with pics from SEMA. Final tuning is still being done. The base tune (first test tune) was making ~530 WHP at 7 PSI but that is certainly not the final number. The car needs to have final tuning done.''

OK
7psi is 47% more air over the atmosphere
47% x 14.7psi = 7psi
lets just say 360 WHP stock
47% x 360 WHP = 529 whp
close huh ?

Lets say it dynoed stock @ 370 WHP
375 WHP x .47% (7psi) = 543 WHP
not as close as before but its pretty close .

Are you forgetting that we are talking about the 3.6L DI V6? It makes 304 at the crank!

and that dyno's at 250ish at the wheels !

edit
I was using a QUOTE from the turbonetics V8 thread(530 Whp @7psi) as an example about how my math works .

Okay, thanks. I was just trying to figure out where those numbers were coming from because they sure aren't V6 stock numbers.

My main point being to get a V6 with 500 WHP , double the WHP (as posted back on the 1st page) you are going to need about double the air (14.7 psi ) .

I won't be holding my breath for that!

There's no dyno sheet cause Turbonetics hasn't published it yet. Either way we can argue semantics all day. My point was simple, not every car requires exactly double the atmospheric pressure to produce double the horsepower. I was simply trying to stress that x PSI does not equal X horsepower. X amount of CFM increase DOES equal X amount of horsepower. I'd prefer to agree to disagree then keep going back forth. You can use your calculations as you see fit and I'll stick with compressor maps, mass flow rates, etc that I use. It's conjecture anyways unless someone figures out how to properlly tune the DIS system on the V6 for daily use.

Is Jay Leno the only FI 6 cyl car so far?

I know this may piss off some off you but I must say that if you want that much HP out of a V6 why did you not buy the V8 to start with. The amount of $$ spent to Supercharge a V6 you could have easily had the V8.
