I havent seen anything on this for a while so I thought I would get the latest opinions.

What is the best belt for a whipple HO. I am going to run a 3.6 pulley although I dont think that makes a difference compared to the 3.4 at 10psi.

If memory serves there were only 2 people making them, Dayco and Gatorback, and people liked the Dayco's better. Is that still true?

Also what is the cheapest place to get one?

Thanks,

Gates now makes a belt in the right length. I was actually sent a gates belt from whipple when I ordered an extra one, but I got the dayco with my supercharger.

I saw someone getting the gates for $40 on M0dularfords.com, but can't remember the post.

And is that the 124.7" belt or the 122.7" belt. I assume the 124. And hey if you can find that post I would appreciate it.

124.7, did you get a dayco with your kit?

Using google the only place I can even find the right belt listed is HCM. For $85.

Diabolical!

The belt that whipple sent me is 125.25"
Is this too long? I've never heard of anyone running a belt longer than 124.7" with the whipple, but my belt came direct from whipple, so I would hope they didn't make a mistake...
BTW, my supercharger pulley is 3.375 inches. Is that what typically comes with the H.O?

copy and paste, change the 0 to an o, you know the drill.

They don't actually say where to get it, but that it should cost $30-$40. You can try Napa and ask them to order it. Let me know how much they want for one.

I have the gates on the car and the dayco in the trunk as a spare.

That's the right pulley, but that belt sounds to long. I'd email them directly and ask what's the deal.

Thats weird, their site only lists 2 possible belts, 124.7 and 122.7. And I am pretty sure 3.375 is right on for 10 psi just most people round it to 3.4.

As long as you arent getting any slip, I would think it is fine.
