Yea, Sox is right... boost rules. I break traction every time I shift a fricken gear when im gunning it!

you may boost any car that you want. the difference between a supercharger and turbo is that with a supercharger, you can only go up to like 10 psi i think. but with a turbo you can go up to as much boost as you want.

Huh? There are many variables that affect how much boost you can run and pretty much all of the same ones can be applied to both SC's and TC's. The number one factor, considering the motor can handle it, is efficiency. How well does it spool up boost without getting hot enough to turn into a big hair drier. Given all things equal, if you want to up the boost on the SC, change the pulley to an overdrive pulley (IE: smaller diameter). If you want to up the boost on the turbo, adjust when your wastegate opens.

If you think you can get as much boost as you want out of a small turbo, you're sorely mistaken. If you run a small turbo past it efficiency range, you'll eventually destroy that turbo, not to mention plumb really hot air into your motor.

As an example, a centrifical supercharger and turborcharger are very alike in design and operation. The compressor side on both of them is the same design for both. The difference is how they are spun. The turbine spins causing the air to get thrown into the compressor housing which compresses the air within the housing. The boost on the SC is limited by the pulley size and RPM. If you want to up the boost, change the pulley, raise the rev limiter, or both. The turbocharger is limited by a wategate. Both are subject to being over-spun, but they can handle being over-spun briefly without major damage.

There are other variables that play into how much boost you can run, just know you can't get as much boost as you want just because you have a turbo.

That can be done NA too. The true test is if you can break traction just rolling on to the throttle after you're in gear.
