Thread: Springs and Retainers??

but 8K is safe on stock S&R right?

I would use them and try revving to 8300 or so and see what the dyno says of the power curve

I would use S&R if i would like to go to 8000 rpms, in fact i readed that stock S&R would fail after 7700 rpms.

Im going to use those cams on my car and i think that with a real good CR i would be able to get nice hp at 8000rpms so... IMO put the S&R they would help you get reliability...

might as well use them if you plan on frequent high revs, or like beto said, take it a little higher to see what the curve looks like

if you have them, and like to rev, why wouldnt you use them.

its like free reliability man.

After tonights baseline pulls, I can hardly wait to see the final results tomorrow.

DPR head is on, ASP budget header is on, S4HL's are finally seated properly in the valve train.

Time for a another power nap

Lets see dyno sheets

looking forward to see that dyno sheet!!!

I don't have a dyno sheet, but IIRC the final number was 150 or 151 on the Dyno Dynamics "heartbreaker". I can say that it feels about the same on the bottom end and absolutely comes alive about 4700-5000 and pulls strong to past 7k. More seat of the pants feedback to follow tonight. Hitting the road in a couple minutes.
