Christian370Z's Progression Thread

I am thinking about Non Stop Tuning crank and alternator pulleys. I am not sure about the side effects of Stillen's under drive crank pulley without balancing that out with an overdrive pulley. What do you think?

this has been explored in technical detail in some earlier threads... my take is low risk but still not much gain so skip it if you have bigger power goals in mind... otherwise why not... the flip side is there are those that argue the risk is high, but those opinions are based on other engines not ours

Someone here had an issue with the pulley working loose and then damaging the seal and causing an oil leak.

Could have been, may not have been torqued tight enough. They may have been confusion over the torque specs which are 33 ft/lbs and then a 1/4 turn more. If it were simply tightened to 33 ft/lbs it would fail.
