    This is a true billet crankshaft machined from billet 4340 core stock - not a cast forging blank that is final machined. Each crank is machined from core stock 4340 on a CNC machine, then nitrided, and final ground.
    We have customers making over 1000 hp with our billet crankshafts 

    As you can see from the table below. The RB34 has a very similar rod/stroke ratio as the Nissan CA18 and Toyota 2JZ both of which love to rev and have been around a long long time.

    With the increased cubic capacity from the 94mm stroker crank, increases of up to 50% in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
