Hi guys

Got a complete B16 JRSC kit fitted to my B18C6 but only resulting in 2-3psi boost, i have tried to find info on the different size pulleys and the differences between the B16 and B18ITR kits without any luck, can someone provide any info? Looking to run 7-9psi.

 

What are you crank pulley? stock Or smaller?
what is the charger pulley diameter?
Did you check for any leak?
also Does your cam timing is changed? advanced Intake?

 

Stock Crank Pulley
Stock B16 supercharger pulley for 7psi ( not sure on size, will measure it )
Stock cams / cam timing. Bone stock b18c6.

Leaks? Well i dont have any idle issues, and i dont believe i have any belt slip issues, boost peaks instanatly to 2-3psi and holds to redline. Looks like a pulley config issue, but im having trouble finding further info.

 

Don't know of any pulley configuration that would give that boost level. Smallest can get to my knowledge is 5-6. If you have a high idle you probably have a vacuum leak. Check all your belts again. They slip easily.
