Tensioner was smack in the middle of its range too. What do you think? Run an 8.4 or 8.8 lower and put the 3.00 on? Or maybe my tensioner is getting tired? I have no idea lol… not used to these issues on a 10 rib setup.

I'd look at a 9.25 like I have with a bigger upper, I'm not making anywhere close to your power but you for sure need a big lower. You know where you can get a bigger one right? Plus a 10 rib and the tensioner should hold all the power you have.

Will Mikes lower pulley work for me? I know Whipple sells them too but I’d rather give Mike the money. I just don’t know if Whipple 10 rib pulley = THPSI 10 rib pulley?

It should line up since Mike keeps that pulley line, I have a 9.25 and 95 up top for a little over 10 psi, if you're at 8.00 now you can really reduce the upper pulley and get rid of that belt slip.

That’s what I’m thinking too. I just sent Mike @ THPSI an email to confirm but that looks like the way to go.

He's in Franch but he should answer your email. Hope it works and it should be an easy swap since you already have and ATI balancer. I think he'll be back this weekend. All this stuff from Mike is 1st class for sure.

Cool and it was fun to have a chat on the phone. Great minds never fail every time, but just a once in a while.

I didn’t recognize the number at first. I was wondering what the telemarketers wanted to sell me. If I had realized it was HORSEPOWER I would have answered on the first ring!
