Think we've had this discussion before lol. I've varied 5+mph with same power and in my opinion theres more to drag racing a manual GTR then making x amount of power and running x MPH. Powerband, driver, gearbox are big factors. Now if the car went out and trapped 120 obviously somethings up but if it went out with a slipping clutch stuffed transfercase and ran low 130's on a terrible pass i have little doubt with a awesome clutch and a brandnew transfercase its a possibility it could run high 130's on a perfect pass with the same power. Now a automatic GTR that uses all of its power efficiently thats a different story.
