basically the way boost was explained to me, was that it was a multiplyer for compression and that at sea level, compression in and TT would be 8.5:1 at 0 bar and say you boosted to 1 bar, compression would be doubled to 17:1 because the air pressure is effectively doubled......now if you boosted an NA to 1 bar, compression would be 10:1 x 2 making the compression 20:1. will someone please correct me if im wrong? you say people were expecting you to blow your motor....but why would that happen if you kept it at a safe boost level? isnt it the same deal for a tt? if you dont keep a safe boost level...youll blow the motor and detonate it to hell. i know the tt has the oil jets pointing at the underside of the pistons for cooling...but if you wanted to run a higher boost im sure you could compensate with a water injection kit or something if you really wanted to...i think turbochargin an NA, especially a convertible is a good idea for just a fun street car because then you would have a bit more low end power with the higher compression...just my .02
