Anybody here running twin turbos?

[AlienInv8r]

it's not a ton more expensive at all.

I was gonna buy my turbos from turbocalculator.com when I was looking into it.
A single T61 from them was $650, and then another $150-200 for the wastegate. So like $800-850 total.
A pair of T3 60's with internal wastegates comes out to under $800 on their site.

Piping doesnt have to be too much more complex. If you're going with a one off kit, it isn't all that much more complicated realistically. Just depends on your goals, mine are currently to save money and pay off my car, lol, so the turbo got put on the back burner

Not alot more piping either, if you run the plumbing simply and correctly.

Well the easiest way is to use oval tubing and run it under tha K like the FFF kit and teufel do. The other way is Incon style and its a pita to get everything just right. If you want to go cheap i still beleive that 2 saab 900 IC's would work fine, for boost to about 12psi (6psi each), and then run it like the twin IC kit from ATI does. Thats just what i was going to do though (when i had money).

Tubular K Member, y the two inlets into one before the IC, and Y the two exhausts into one before the Cat. simple stuff

Nope. Either they're both running 6 or they're both running 12. Boost is not effected by another turbo running the same pressure, volume is. If X turbo is running 15 psi and producing Y volume, add another x turbo, and 2x turbo's combined pressure will still be 15psi, but volume will be increased to Z amount.

CFM is CFM

Ive seen somewhere on cardomain one guy had front forwarded headers, damn nice job. And you can simply put twins right on them + 2 core ATI intercooler would look really nice and would perform even better!
1. Turbos right on the headers. Hot!
2. No pipe under K member
3. Travel from right bank to the turbo on the FFF kit is almost the same as STS!
Questions ? Suggestions?

its just tough to squeeze 2 turbos in front and it will cost you a lot to get custom forward swept manifolds made.

Use Pace setters, cut the flange off, weld a T3 flange on there, and bolt the turbos on. Install a scavenge pump (around $600). Done.


Why are you people SOOOOOOO determined to convince everyone that twin turbos are so damned expensive and it takes a million times more piping, and they're so complicated, and not worth the 'gains'?! It's stupid. If you're smart about it, you could do it for not much more, or the same amount as a single. You people who have never built a TT car need to stop blindly telling everyone that it's 'not worth the gains' and 'too expensive'

I've always wondered that myself, everytime I go to think about it, it almost seems the piping could be less complicated since I wouldnt need to worry about a crossover pipe for the single, and the ATI intercoolers are a perfect match for the setup.

TH - on the topic of the pacesetters, can they handle the heat a turbo header would create? I don't know a ton about metal expansion and such, but if I could just do that with my pacesetters that are sitting on the side of my house it would simplify costs a ton for me.

Yes , but I personally think that is the only correct way of turbocharging v6 engine. you will get :
1. True, correct manifolds over the stock(those are terrible)
2. Shortest engine-turbo distance.
You can’t beat it with the price because you would have to get better mani anyways, why just don’t get the correct ones?
For the room upfront – I don’t think its gonna be a problem, especially twins would be smaller, im not talking about VNT`s.

[/QB]</font>[/QUOTE]Do you think they will fit? I lifted the car yesterday just to see if it possible to do that. And if I could get turbos right on stock manis, on passenger side you can argue about , but on the drivers side that would be to tight. Unless pacesetters are different (you are talking about those : http://www.pacesetterexhaust.com/camaro.htm ?)

I'm positive. I'd still get them coated, but i don't think they'd have an issue at all.

Yep, i'm talking about these http://www.pacesetterexhaust.com/images/72c1209.jpg

Fitting might be close, but it can be done. LS1s manage to fit 2 GT35s in there, so two 16Gs or something shouldn't be too much of a problem. Some other minor fabrication to the headers might be needed too.
