No need to crawl through the maps of many turbos, factoring in converter, gears, tire/wheel sizes, car weight, fuel quality, target boost pressure, piston ring gap and engine management but most importantly, one should never comment on the PY boost section in fear of upsetting the retired boost engineer. But when the advertisement said I would make 635whp at 10psi on the hub dyno with me tuning it in a car designed purely for the street that also just finished a 600 non-eventful-and-reliable mile trip because the wifes Subaru has head gasket issues, god dammit, I just had to have it.
Have fun guys! I'm out.  |
I have not seen any Engines mounted on hub dynos going down the actual race track. Hub dynos do not include AERO or tire losses.
Facts vs partial knowledge of actual racing influences. Bragging, nothing more.

Same BS happened with Carb Flow Advertising. Instead to using a standard 20.4" H2O test flow point, you go to 28" of test pressure as it reports a bigger carb flow number. ADVERTISING.
