Title: Front Pulley Revs
Post by: Jmorganix on October 05, 2008, 09:24:39 PM

It has always been my understanding that the M42 front pulley, balancer, etc will come apart if reved over 7,000 R's for any length of time. Have you guyz found this to be true?
Has anyone made a billet assembly to replace the stamped original stuff?

+1, not true.

there is quite a few people running above 7 grand with no problems.

hell, i've had my m42 up to 8,100 by accident for a good 10 seconds before (stand alone ecu) and it has 300,000 on it, this was about 15,000 ago though, and it still runs great.
