I'm toying with the idea of replacing my roots 8-71 with a quad rotor setup...however I have some questions...

1. I won't be buying new as I don't want to spend that kind of money....that being said...I found a setup without an intake...is there an adapter to bolt this to my current -71 intake/chiller or do they take a special purpose built intake?

2. I have found several efi versions...however I would prefer a carb setup as I am already setup for carbs/holley throttle body efi...my question is can a person remove the efi throttle body from the rear of the whipples and either make or buy an adapter to run them on carbs? I know the whipple efi setup works however I have carb based throttle body efi stuff already that is still in the box and would hate it to go to waste.

3. Will the quad rotor setup work with a 3 v accessory pulley or will I have to covert everything to serpentine?

Thanks!

I’ve never seen 1 sold separately.
Ive also never seen 2, been thinking about tooling one up.

Is 1 something that could be made to work or is it like drastically different than mounting a -71? I've never seen the underside of a quad rotor so I honestly don't know how they mount??

And if I decide to pull the trigger on this...maybe I can be your guinea pig lol...Peoria isn't that far from me??

Check out their website. You can definately use whipples intake and be able to accommodate 6-71 through 14-71. May require some adapter plates. Going the other way from your traditional roots intake to that of whipple not certain. Whipples intake is completely open plenum. Here's a pic and some info.

Yea I saw that so worst case I could buy that...thing is I have a blower shop intercooler now and would like to retain that although I may not even need an intercooler with the whipples...no way in hell I'm paying whipples prices for their intercooler...not happening lol

Might just have to fab my own adapter...I think the base of the 8-71 might actually be wider than the mounting plate of the whipples but not sure on that.

If you can get me parts or drawings, I can model it and get it quoted. I wouldn’t likely have it made locally unless you hate money. I use a Chinese shop at my day job that is currently setting up a Mexico facility. If we’re feeling patriotic I can try to find some
US casting suppliers.

About the 3v question. That's what I ran on mine. I believe that Eddie had to mill the crank pulley. I have some bullet proof blower pulley studs that I will sell you if the whipples are the style that are vented through the pulley shafts.

Eddie Young has been mentioned - but that is who I was going to suggest that you contact. He will know what is needed/necessary.

I think the real question here, is how much power are you looking to make? A good 8-71 will support 900-1000HP. If youre looking to make more than that, a bigger roots, or whipple would be the way to go. Theres no denying screws are better than roots, but at the end of the day, do you wanna go boating, or want to spend a fortune on a custom setup...plus you have to think of what the hull will handle. No point in putting a 1200hp quad rotor setup in a hull that is gonna get sketchy at 90mph, or in front of a drive that isnt a #6, M8, etc, Sometimes its best to keep things simple, and enjoy a few beers on the water!
