How do you JRSC guys think these will do as compared with CTR/ITR or GSR Intake/CTR exhaust setup in a stock GSR with an Endyn ported blower running 13 lbs (LHT Intercooled)? I found a GREAT price on these(less than $200 BNIB), and am wondering how well they will work. Should I go w/ them or just try to find a set of CTR/ITR cams for a good price?

Specs: Lift / Duration IN. 0.409,223; EX. 0.394,227

Thanks in advance!

 

for any boosted app use either itr or ctr or sk2 stage 1 tuner you will end up lossing hp and gainging.

 

kind of a big statement.

what about the guys runnign the PRO1s and 2s seeing 80-100hp gain over their previous cam? Some of those previous cams being the ones you mentioned?

 

ctr/itr and sk2 tuner stage 1.2 wil for from him. youll need tunning.

 

Turbos and Roots blowers do not react the same way to cams. Big N/A cams have lost me power on JRSC setups.

I'm using Crower Stage 2 turbo/SC cams now and they work well. I'd stick to GSR-I/ITR-E or some short duration turbo cams.
