hey has anyone installed or heard of how the GMPP adjustable cam gears are or how much hp is gained? its part number 88958613 and how much would like stage 1 or stage 2 cams do on hp for us 2.2 owners? i go thte gm sport compact performance build book and thats where i got this from. cause im prolly just gonna get the intake, exhaust, cam gears, cams maybe depending on what you guys say and know about this thanks ya'll

 

We have sold many sets. They work great, i have them on my Ecotec Cavalier. Email me @ Aaron@TurboTechRacing.com we can get them cheaper for you than any GM dealer, and even cheaper than www.GMPartsDirect.com

 

i was wondering what all these numbers meant in terms of performance.

Im sure your tired of hearing this but the cam gear will adjust timing in relation to tdc. I is a support mod and won't add much if any horsepower by itself. What it is good for is tunig your sysytem once you get lots of aftermarket parts. Ther are tons of theorist out there giving their formulaic approach to timing adjustments, like take out 2 degrees for every 50 shot of nitrous, or soo much boost you should pull timing. Best place to sort this out is on the dyno. I will tell you going with a stage 2 cam may affect drivablility drastically, and you may run into idleing and starting problems. Not 100% on that one, but in a Camaro no good. I have alot of Chevy v8 experience and those cars respond exceptionally well to head anc cam packages, but I'd say with the small displacement of our motors probably negligable gains. You would do much better to add an external power adder nitrous turbo super or such. Then you can buy a new motor for roughly 400 bux and race build it with all the forged titianium or whatever you want parts, because you have the power to warrant those type of upgrades.
Have fun

 

Using the adjustable cam gears allows you to change when the horsepower peak is attained. Advancing the cams will bring on the peak sooner and retarding the cams makes the horsepower peak shift to higher RPMs. They will not increase your horsepower levels. The camshaft set listed in the GM performance engine book is for a racing engine and will not work well with your 2.2L computer.

The Stage 1 and Stage 2 Comp Cams that have been talked about in several threads will work with the computer but the increase in horsepower has not been made available -- without knowing what the factory cam specs are it is impossible to estimate what these cams will do for a 2.2L. Only a serious dragstrip-timed evaluation would provide the answer and I don't think anybody has done this. Unless you want to be the guinea pig for testing these products you should wait until more information is made available. Because the Cobalt is still new and most are under warranty few people want to take a shot at throwing away their warranty to gain a little more horsepower. Just stick to the externals for now -- intake, exhaust, and/or manifold/header.

 

two of those cams are blanks which need to be custom ground, pretty much not necessary if you dont plan on going really wild with the build. turbo, s/c, and nitrous engines have different torque/hp curves, so these blanks would be ground to your specific engine...

 

Do they have GM cam Gears for the SS/SC? and if so do you keep your warnity with the gm parts?

 

you guys are these cams tri-flows,if not wait a month Im JBP will have some for ya

 

I have the set. Presently they are set at Zero degrees, so stock. You can not make adjustments to it until you have the ability to tune the ECM, which the 2005-06 model don't have yet.

As for Cams themselves...

Kindda the same boat. You could put different cams in, but without the ability to tune (specifically the injector bandwidth and timing), you won't get the most out of them.

Cams are a pretty advanced thing. However, more and more people are asking about them lately as a result of three different engines and more choices now. I might be making a sticky soon listing all of the ones available.

 

If you can make a sticky with this it will be great,your knowledge is always great and easy to understand
