hey guys i'm needing to hear how safe it will be to run a stock motor with this pulley.i have the 8psi pulley but just want the power alittle sooner. keep in mind i will be not beating on this car meaning not going to 9grand more like 8 on the rare occasion. any help will be great guys.

 

you should be fine with the stock motor (block, head, pisotns, etc..)
but if you boost higher than 9 psi you WILL need bigger injectors 750cc, Some sort of Engine management AEM EMS, a 2mm head gasket to lower compression 1 point, etc..
There are people here pushin 15-17psi with stock motor, i will be pushing 15psi in the near future!
Good luck

 

WTFFFF, how many whp do u get with that?? lol. My friend with a 10 pully got 370whp. (of course with all bolt ons injectors and a Aem Ems) Im sure that wouldnt be safe lol.

 

if you want safe with stock motor stay under 10lbs

 

thanks guys. i have 750 rc's,and the aem ems just didn't want to rev it pass 8 to make 9psi.
