I was thinking of getting them for my zc what do you think?

I have had pullies on other cars and it made quite a difference but there was also 8 cylinders on those cars.

ive been told they make your main bearing seal leak oil do a search on pullys, theres been a few threads lately

that's if you replace the crank pulley which happens to be the harmonic balancer too... the Tru Power replaces accessory pulleys which is acceptable.

ok ok, cunfused the crank pulley with AEM power pullies....will there be any noticable gains? cuz i think they are kinda pricey..??

no, just be a little peppier and better throttle reponse, better mileage if you don't beat it.

I thought the harmonic balancer was only for 6 cylinder engines. Inline for don't need them???

heard the tru-power pulley's only good if you have a blower

YO, dunno why that would be... AEM doesn't even make a blower... besides that anything that helps a blower helps an N/A motor too cuz they operate very closely

Brett, inline engines have the worst dynamics out of all of them almost. V8 and most V6 are at 60 degree Vs so at least some of the motion goes towards cancelling each other out. VR6 is at a 15 degree V... inline engines all move up and down together - not opposing each other. Subaru and Porsche flat motors have the best dynamics out there!

ya true i was thinking of getting pullies for my zc too what you guys think any gain

Brett

Okay, I thought that the dynamics dealt with the froces created by having muliple banks of cylinders not in line with each other... But it seems that it is the angle which the cylinders are on realative to the crank which is the issue. Thanks for the clarification!
