Use that number as your baseline for any modifications in calculating crank hp. So, if I add a tune and turn out 340whp, then my crank would be 382. At this point all 3 variables have been accounted for. Then there is the overrated crowd that takes this down a different path... because I also put down 295wtq  |
That makes perfect sense but how would you have the flywheel number? The manufacturers stated number is not a standard that every car produced will make, not exactly anyways
