A memeber recently made 1250whp with a straight RB25 stock crank, built everything else..
I have personally made around 500whp trapped 128mph (full weight S14 W/AC)
I will be tuning my RB25 combo (25 bottom end with 26 head) soon, hoping to break 750whp
Darius has also made 660whp or so if my memory is correct, straight Rb25 as well
