On Mike Murillo’s dyno M6 thunders to 650 rwhp @ 6300 rpm and 547rwft @ 5700 rpm with a conservative 325 hp shot of nitrous. The cam shaft swap proved to be the main ingredient for the EFI the show its full potential.
The motor tune was almost perfect with great idle qualities and part throttle performance for race car. We did some staggered jetting on the nitrous and all the plugs look great. We also played with the timing curve and found 25 hp.
It just all around runs better with NO head gasket leaks!
