right. larry hasnt fooled anyone. there's no doubt in my mind he made those numbers on that boost. The lotus head is superior to the 8v head in flow. Look at the hondas, they only run 10psi where we have to do 20+ in the 8v's. I also couldnt agree more on how crappy the factory exhaust is. On my 86 non intercooled early T1 Daytona, just gutting the cat alone gave me an extra psi or 2 of boost. and that was still keeping the tiny tailpipe. Turbocars show HUGE gains on the exhaust side
