car has
vararam CAI
american racing headers + x pipe

i used one of these with tsp .650 lift springs and it floated the valves and had ptv and ran slower and slower till I pulled the motor.

I was told to use the comps and I wouldn't have had any issues.

Something is wrong, you should be around 470-480 rwhp with that setup.

Where did you get the specs from? Aren't those 'top secret'?

This is with comp 921's. It ran fine for months, just noticed this while doing some upgrades.

I would look into the comp 926 springs they are good for .675 and have really good seat and open pressures. Just my .2

I guess it's not a secret any more lol, if they are right I thought it was a bigger cam than I thought. Not bad though but there are better cams for sure lol

I don't think any other cam has consistenly shown as good of results as the g6x3. But also it's aggressive as fuck compared to what most guys run. I can see why so many have spring issues.

Was the cam installed a tooth off maybe. I have seen that happen, and the car will not make anywhere near the power that it should.

No, the car made power.

Did u notice any type of power loss or valve train noise?

It did lose about 10-15 on the dyno, but that was hardly noticeable in "mexico".

Apparently it didn't make the power you were looking for. If that's all the power you gained from a healthy cam swap and the FAST, it could definitly be off a tooth, even if it gained a couple of hp from the baseline run. I've seen it happen in person. Might be something to check - or not. Whatever floats your boat. Either that, or the tune is WAY off.

You have my situation and the OP's mixed up.

That cam was worth about 60 rwhp in the situation I'm talking about. Later on it was noticed that the car was down about 10-15 rwhp after taking it back to get retuned because some things were added. All is fixed now and is making more power than ever do to even more upgrades. Cam isn't a tooth off nor is the tune off...

Even without the 102 FAST setup and the stock LS3 stuff it should make that.

Yeah, my posts were intended for the OP. not sure how I missed that that's not where they were being directed.

How the hell did you get a 235 duration .647" lift cam to clear the pistons on a 107ICL?!?!

It is very possible you don't have enough fuel in the tune. 107 ICL with a 111 LSA runs fuel out the exhaust during overlap. (why do you think tight LSA gets bad gas mileage, injector puts all the fuel at the valve before it opens. The back half of the air-charge has almost no fuel in it) Would prefer a 109 ICL but 107 works...If you don't run that cam at 11.5-12.0 by an AFR gauge, it wont make power. With 42lb injectors, your IDC should be 85+% at 6500+ if you have the right amount of fuel in it. Tune for plugs and power, an AFR gauge is just for reference. If it make best power at 11.4, then just know that is your target. Keep adding fuel till the power falls off across the board.

I have one that looks just like that, its not enough PTV clearance. Only one right way to check it that is with adjustable pushrods and checker springs and zero lash. If you run to much preload and they float they pump up and hit. ! If you have 60 thou preload you can pump up 60 x 1.7! 102 thou. Run as little preload as you can and as much spring as possible, the 921s arent enough spring. I run 50 thou ptv all the time on hydraulics on the intake but I run very low preload and a lot of spring. If you have 80 thou ptv u can only have 50 thou preload. Remember 1 full turn is more like 70 thou preload (if u measure it with checkers). Always use this rule and u will never have this issue again.
