Re: Supercharged vs. Turbo

[Kevin <aventari@cts.com>]

You dont need to change the pistons with a low boost system. I'm going to
run an 8psi turbo on stock Mahle HPC coated pistons (we'll see how this
works, but i think it will) my BAE turbo manual says the system can be used
on a stock engine. Granted it's not a good idea, you need to change a lot
of minor things, but pistons aren't one of them.
