if i remember correctly the last turbo setup made around 400hp? 500 doesn't sound too out of reach for the new stuff... but last i talked to him it still wasnt tuned yet
As for the whp...in the woods of 500whp is what I want on race gas...pump were looking around 420ish....the 650 is my feel-good flywheel calculation for the magazine haha (based off the whp on race gas)
