And because it has high comp pistons big turbo and running on e98 doesn't mean it's suddenly going to make 300-400 more hp compared to low com pistons, average size turbo and on gas or c16 or something...
cyl head gonna dictate your power. In the past, hi compression turbo builds targeted response & low boost efficieny
Dunno whats up these days. From reading, not all combustion chamber designs will benefit from that as others
If it did more people would of done the same
most travel the beaten path, to keep it simple, while achieving their max goal with the min input
Like the two 10sec street cars mentioned, plus a 1.6 MR2 8:1 gt30 25psi that went 10.6
u obviously got bigger fish to fry, with a substantially more aggresive goal & setup
