Im thinking of putting on a 125-175 shot of N20. Car already dynoed 533 RWHP. It has a sportsman block and forged internals. I am impaient and dont have enough money for a crank right now. You think it could handle it?
I have made 560 to the wheels on a stock crank with a balanced rotating assembly. The big key is to have it balanced well and to keep the revs below 6k to make it live. I plan on making my stock crank travel well into the 135 plus mph range.
It all depends on how hard and how much you drive the car. The stock short block could handle 800rwhp for a few trips down the quarter mile. Fatigue is what breaks parts, not just outright power.
