Whipple pulley question

11bravoss · 05-22-2018, 05:55 PM

I'm trying to see who has experience with a whipple on a zl1? Im trying to figure out what size pulley I should run on my whipple. Mods besides the whipple are 38% cam, headers, ported tb, ati damper with 9.17 lower pulley(15% od), dsx aux fuel pump and e85. And ported heads once I decide where.

Call Vengeance Racing or Katech, I know both of them have done quite a bit of work with the 2.9L Whipple on these cars.

Wasn't sure if they would help me out considering they are not doing the work

I think they will. David at Vengeance has helped me out many times. I called or emailed just because I think they're an extremely reputable shop, told them up front that I likely won't be getting the work done by them and I just needed some info/advice. He was more than happy to help the times I reached out.

Ok I'll try that. I appreciate it.

I'm running a Whipple, ported heads, BTR 38% cam, 9.17 lower, and 3.0 upper and making just over 17psi. I also have the DSX aux fuel pump and my fuel pressure is good.

Awesome, thank you. What's your hp at? Also do you know what size belt you are running or part number?

Are you using E85 and/or Meth at all?

So far it's pump gas and meth. Going to tune it on race gas and meth also.
