What is max hp a 8 rib can handle. Also is 600 rwhp possible on a p-1sc or even a d-1sc. This will be on a built 355 or 383 lt1. Thanks

 

Anyone ?

 

I have an 8 rib and SDCE tensioner on my F1A. I'm making around 600rwhp with a 4.25" pulley. Lots more choices on belts sizes and their cheaper too. I'm getting good longevity out of my belts and they are not stretching or slipping. Idler pulley has only minimal wear.

 

My car went 9.38 @148 with an 8 rib on a YS trim at 3420 lbs.

 

And that 8 rib setup still works good. Anything look familiar here?....

 

LOL .....Thats a nice setup you have there!

 

Sure is. I had a crank pulley spacer machined to take place of the crank trigger setup. After measuring for it, it lined up perfectly. I didn't have the reverse thread nut for the idler pulley when i got it though. Who would have though a reverse thread nut of that pitch would have been as hard to find as it was. I bought a few of them. Nice setup though i must say. Cudos!

Looks kinda like mine, hehe. I got the cog drive though.

 

we made 600rwhp widh a overspinned p1sc on a 383, cc305, ported stock heads, Ati twin IC.

 

that looks like mine... So i guess i'm good to go...

Chris.. Care to post your pulley sizes you did to achieve that? and where you using an auto or manual? What belt part number do I need?

I guess i'll be able to hit the 150 i want with the 2.75"

THANKS!
