At sea level or 10,000 ASL!

I didn't think it mattered

Tis what I'm saying...

Installed 48# injectors so there are a few other things you have to take into the tune but really no harder than any other modded SHO. Clutch in and rolling I can still get some mad surging but I figure its just the nature of the beast it only as 10-12 inches mercury vac at 1100 idle.

Hmmm. Better start saving my pennies for some pistons.

Awesome #'s Marcel --- kudos.

.375 lift on both cams 228 deg on Intake and 216 deg on Exhaust with 26 deg of over lap.
Cranking Comp was 210-215 psi.

basicly if shonut had offered plus 30 cams these would be it haha..

hows the idle with these cams?

Is rough. But I love it. It won't idle at all below 900. I have it set to 1100. And I had the vac gauge on today checking fuel pressure at was only getting only 10 in mercury at 1100 rpm

 

[yamahaSHO]

I idle at 1,200 now (was 1,150) and I only see 10 in/hg at idle with SS stage 1 cams (I imagine forcing air on the TB doesn't help).

If your idle is still rough, try a 13.5:1 - 13:1 mixture at idle. This cleared my idle up (hot over-lapping cams generally require more fuel to run smooth at idle)

 

[Sho Amo]

Good info Jason. Im gonna try that with Scotts tri-flows.

 

[Ishodu]

Could likely play with injector timing as well so that not as much of the fuel is going out the tail pipes.
