What's the maximum lift Comp 918 springs can handle?
My car has comp 918's in it and I'm going to go with a bigger cam. I'd like to get one that is like .595 lift.
I've heard that 918's are good for .600 lift; but would like some input.
What do you guys think and what is the biggest lift cam people have run with the 918's?
Thanks.

Comp rates the springs for 600, but reccomends them for cams around the size of .609, you can get away with running them to about max of .605 to .609. This is where coil bond begins to become a factor. I would change them more often if you are using a large lift cam.

If I go with a cam with like .581 lift, would I have any issues? I don't want to be changing springs as it is a total pain in the butt.
I guess it is easier on the vette; but I still don't like the idea. Right now I have an ls6 cam and want something bigger with a better lope.

It somewhat depends on the install heigth but not that crutial unless you are running a spring at it's max.

with springs..you want atleast .060" before you get to coilbind...that being said and going by the spes of the 918 spring you can run that spring on a cam that has a lift of .655"...but like others have said it also depends on the ramp rates of the cam on how long the springs will last

We run the TSP 231.237 camshaft with 598 595 lift on them without any issues. You could also look at the Manley springs, we've run them to 598 also

Does the duration have any affect, or is it just lift?
For example, I have a MMS 229/229 575/575 with the 987's and YT's. I Have read about the probs with that combo and was thinking about switching to 918's. Will this be ok?
