Marvin,
derf has done some tinkering to his T25 car. What all has been done, I don't know, and I don't know that I've even asked derf to elaborate.
20-21 psi absolute pressure would mean only 5-6 psi of boost, which is certainly not what derf is talking about.
As for the normally aspirated cars making 150 HP, that's true, but pumping 14.7 psi into a turbo car is not the same as 14.7 psi in a NA car. The reason being that NA cars have a compression ratio of about 10.5:1, while the turbo cars have a compression ratio of 8:1.
Cheers,
~Peter
