Whipple Gen 3 or Gen 4 Question

[Whitedevil95]

So I currently have a pretty mild Whipple Gen 3 set up on E85 and a 3.5 6 rib Pulley making around 750rwhp through the auto(only dynoed it once on a "low reading" dyno). I was wondering what these head units are capable of for power? What pulley combos, boost levels, and power have some of your guys made with a Gen 3 or 4 set up?

I don't know about "power" it will depend on a lot of factors, but should be capable of close to 1000. I'm running 3.125 (16 pound on E85) 6rib on 11:1 Gen 2 Whipple and trapped 142MPH at 9.6 ET on 1975 DA in the not drag friendly weather here in Puerto Rico and plan to drop to 2.85-2.75 as soon as the 11mm head studs are in stock again. So you have a lot of head room before running out of blower.

Ok thats what i was thinking. I knew I had heard it was somewhere around 1000rwhp before its maxed.

The jump in power from Gen 2-3 made the most and then 4 i would say update it if you had a Gen 2. I made 820rwhp on my gen3, 3.5 pulley and 110 race gas. I had a fuel system
But i sold the car before i ever got to run e85 BUT this headunits are 900+ conservatively.
The biggest issue you’ll have is belt slip when making power and most likely have to go with a 10rib if you’re truly spinning it. My griptec was fine on the 3.5 but smaller on the 6 rib would most likely cause that belt slip

Cool that's what I was thinking. Currently I need to really maximize this combo at the track before I make and power changes. It should be a 10.0-9.99ish car as it sits. But we will see for sure soon. I think if I want more power it will be 10 rib kit or Turbo Time.
