Does anybody have the CRV crank pulley on their JRSC gsr?? I was wondering what kinda WHP numbers this setup is capable of and what feul upgrades and internal upgrades are required. Thanks.

 

I wouldnt go with a CRV pulley even tho its a cheap upgrade. The pulley isnt meant to spin as fast as the GSR makes it. This in turn causes the alternators components to wear our prematurely, Id go with the ENDYN stepper puller, its made specifically for this application.
To answer your question the whp varies on the engine set up but a stepper pulley is good for 2-3psi of boost depending on your exhaust set up
