THE ZL1 SPEED SHOP HAS USED MOLNAR TECHNOLOGIES FORGED CRANKSHAFTS IN OVER 50 ENGINES IN THE RECENT YEARS --SOME TWIN TURBO ALCOHOL ENGINES CAPABLE OF OVER 2000HP. 

WE USE TO USE $1200-$2200 CRANKSHAFTS AT ONE POINT IN TIME FOR ENGINES OVER 1000HP, AS WE KNEW SCAT, EAGLE, CALLIES COMPSTAR WERE NOT RELIABLE AT THESE POWER LEVELS.

AFTER TALKING TO TOM MOLNAR ABOUT THE LIMITATIONS OF HIS CRANKSHAFTS, WE DECIDED THAT THEY WERE UP TO THE TASK. SO, WE BEGAN USING MOLNAR CRANK IN MOST OF OUR ENGINES TO 2000HP--THIS WAS AROUND FOUR YEARS AGO.

IN THIS TIME, WE HAVE NEVER SEEN ANY FAILED CRANKS OR CONNECTING RODS IN MOLNAR BRAND THAT BROKE OR FAILED DUE TO HIGH HORSEPOWER LOADS WHEN USED IN A BLOCK AND WITH OTHER PARTS RATED TO SAME POWER LEVEL, AND TUNED PROPERLY. BUY WITH CONFIDENCE!
