on stock everything??
top mount, 7 psi, stock exhaust(less then 2 inch diameter in downpipe) all stock everything even a paper element???
plus fwd has less drivetrain loss dont forget…
now if your talking full exhaust, more boost, intake,fmic, stock turbo…then 250-270 wheel is max cause thats when the maf maxes out roughly…
now if you talking stock motor with everything else then like i said 500+wheel is possible…
