What pitch for my prop?
I've been having nagging rev-limiter issues with my SHO....as in it sits at 7750 rpm popping off the limiter constantly. Checked prop/wear ring clearance at Riva and they said it was OK...not great...but OK.
I think with the mods i have...it's time to repitch the prop. Any suggestions u guys could give me would be great as i'm sending the prop out to Impros today.
Oh...and whats the pitch on the stocker?

I think the stocker is a 12/20.
I was hitting the limiter and went with a 13/23 to resolve knowing that I will be going to a stage 2 or greater anyway and who knows what Riva or RD will recommend for that...
I still have the stock S/C wheel. By going to a 13/23 I probably lost a bit on low/mid. This was most noticable to me in the hotshot.

I'm using the 13/23 Ska from R&D now. My buddy uses the 13/24 on his SHO. Both of us installed along with R&D's Monster Charger Wheels. No rev limiter now except in big air, full throttle, haha, but not the little stuff. No loss of low-mid range pwr with the new charger wheel, just the opposite.

Rip, I am going with the 13/23 as soon as I can scrape a few pennies together.

Now that you installed the manifold sleeve I would go 12/21 or 12/22 based on R&D's rec. Since you will most likely have a different setup by summer your best bet might be the taller 22 to keep you off the limiter in the cooler air/water. Might lose a little on the bottom for wave jumping though. Without adding more boost I think anything bigger will be a dog off the line. Eventually you'll want a 2nd one but I'd wait till you do more mods...never can have too many while tuning...I just bought a 3rd for my GPR. Let me know when you want to get together for the bucket party.

Sorry, my bad, yes Pro Pitch is what it is!!

And whatever it is fellas, I OWN the holeshot with that new C1 Charger wheel and that 13/23 prop. We just need a lil more top-end on the SHO's is all.

Mine was a Skat Trak 155-75-25 (SY557525SW1320)
That they repitch to 13/23. Bought that back in September I think...

Not sure what more I can do. Still have the Intercooler Core Kit comin from R&D, that had to be manufactured on order. Hoping once get a few more hours she'll free up a bit more. Then guess we just wait till new ECU out and see where that mother takes us, lol.
