I have a stock cam in a 2007 l33 and about 5200-5300 rpm it seems to level off noticeably. the engine is turbocharged but other than head studs and gaskets its all stock. just curious of the rpm limits of the cam, forgot it does have brian tooley .660 duel springs also.

Sounds like you found the limit of the stock cam...

Stock cam will only flow so much, and it sounds like you have found that point. Spinning it faster wont yield more power, but in fact the opposite.

My guess is that your lifters are being "compressed".

What is the nose pressure of your BTR springs ?

This statement is NOT to "demean" his "bit of kit", just a fair question ?

MY case, West Tech < Comp> cam, all failed, stock Z-06 camshaft, 1200 HP @ 22 .lbs. (circa 2006)

There could be a greater problem of concern ?

thanks for the replys

fisherboys

I don't know at this point but I will find out

fisherboys

Thanks for graph, that makes sense. I was hoping it wasn't something else

fisherboys

Anything specific that you may be thinking could be the greater concern? Thanks again

Why did you change to a dual spring with the factory camshaft?

fisherboys

I have a tick stage 2 cam that I was going to put in but wanted to see how it would run with the stock cam. I had the springs already installed.

Hi again, we here must take what you state as correct "all stock except".

My question would be related to your fitted fuel injector, the flow ?
