Has anybody used the Endyn stepper pulley with their JRSC? any problems with belt slippage?

also.. stock JRSC boost is 5psi correct? so with the stepper pulley it will jump to 8

 

Ive used the upgrade pulley from JRSC and made 11 psi of boost.

Anyone use the CRV pulley on a stock B16?

 

bump. How much boost does a crv pulley yeild on an otherwise stock JRSC

 

I got 10psi out of my crv crank pulley.

 

i got 9.5 with a crv on a type R

 

I would NOT buy the endyne pulley because of fitment issues if you want a pulley that fits right with no hassles and comes with the proper size belt then I would get this from motorvations motorsports. Jim is the owner and all he does is specialize in JRSC tuning and parts. here is his #205-661-3600 he will help you out and answer your questions. also if you were to have a problem he would take care of you rather than saying well it should of fit and tough ****

 

Exactly...the MVM pulley is a much better fit, and was designed to eliminate the slipping issues associated with the Endyn pulley. Definitely give Jim a call....his customer service is outstanding as well, as he is ALWAYS willing to help you with any problems you may have. Good guy to know

 

Go Jims MVM...I know I am and currently I have the ENDYN on my car, slip city. The ENDYN has caused me nothing but headaches.

 

thanks a lot exactly the info i was waitin for.

what makes the mvm pulley better so much better. anybody using this pulley?

does it overdrive 12% or whatever to give ~3psi?

 

First off, it actually fits, unlike the Endyn which sometimes only has 2 threads to grab onto. The poor fitment has actually caused a few people to experience the pulley flying off under boost...which obviously is ridiculous.

In terms of slipping, I know Endyn supposedly used some "coating" on the pulley to prevent slipping, and when this coating came off, its history. Who knows if thats even true. The MVM pulley was designed to resist slipping naturally, as a larger stepper surface will increase contact area and therefore decrease slipping. Thats how I understand it...Im sure Jim can go into more detail.
