how do you figure that? SC12 with 15psi on a 1.6L might be a problem, but on an 1100 or 1300 motor? isn't it a combination of temp from compression AND temp from high lbe speed that causes the lobes' coating to fail?[/quote]
One thing to say, you know too much, good work. What would a turbo go like on a 3k? lol!
Thanks
