So I currently have a forged shortblock with 16cc pistons and Factory PI heads and cams making roughly 400whp on 12lbs of boost with a vortech V3 blower. Im looking to switch over to the CMS 2.5 blower cams and their stg2 springs. What type of power increases can I expect with these cams. I'll be spinning the rpms higher with these cams so will probably be making more boost too.

Id say easily 65+. i went from 425whp at 11psi on a V2 s trim to 482 with a stage 1 cam @12psi,i gained 1lb of boost by getting rid my power pipe.

Nice was that on factory heads? Those are some good numbers. My runs were on a loaded dyno.

do you have a tuned idle video?? can you make one?
I second this I would love to hear them. The guy I bought the cams from sent me an idle video on his car.... I like :)


Also practicing removing the valve springs on a spare motor I have. This tool is really neat. Cams are currently at modular head shop right now getting degreed.

I love mine they sound great to
Found your vids on youtube. You made some really good power. What size pulley are you using. I have a 3.15 on my V3 right now, would do about 12lbs of boost @6k rpm looking to spin about 6500 now. What is your fuel setup?

Idle sounds better now tuned and warmed up. Im using a 3.12 and 15% overdrive. My belt started slipping not long after the dyno session but lasted awhile lightly slipping before it got to bad. i definately need an 8 rib kit before next season. Fuel is Return with sumped tank, aeromotive a1000 external pump, aeromotive fuel pump control box, deka 60# injectors. Hpx slotsyle maf apparently almost maxed in 3" tube.

Wow you got a serious fuel setup. I'm going to a 340lph in tank pump with deka 60lbrs and a vmp5000 maf

What are your hp goals? I'm running a V2 s trim with a 3.33 stage 1 cams and a single 340lph pump return less with 4#injectors and a JMS feulmax and Ive got plenty of fuel at 480whp @12psi

Well currently I just have a 255lph pump return system, vmp 5000 slot maf and the 60lb dekas. With the new cams and higher rpm I will be around 16lbs of boost. I'm thinking the 255 pump will be out of juice not to mention I have the 98 bastard year fuel system. So I'm switching to the mid 80s to 97 tank and bigger pump. Would like upper 400's low 500's

Interesting.....

What is the JMS fuelmax? is that like a Boost a Pump?

I have a V1 upgraded to Si trim intercooled, 3.125 pulley making 13psi, 340 pump returnless, 42 pound EV1 injectors and VMP slot MAF. I maxed my pump out at 448whp @6300 RPM. Tuner told me he could have carried it out to 6500 with 60lb injectors. I'm going to install my Boost a Pump and 80lb injectors soon but am collecting things for a return system as well.

Its cool how so many of these setups seem so similar but are still so different.
