Whipple 2.9 2017 GT

[Macht87]

Ok so I'm going to throw it out there. I am a comple newb when it comes to superchargers. I have always been a turbo guy.

I have the opportunity to get into a whipple 2.9 for cheap. Looking for advice on what size pulley I should get.

Here is what is done to the car, Kooks LT W/green cats, Double H, borla Type-S, GT350 CAI and TB.

I have a set of ID1050 injectors on the way along with a Fore duel pump setup. I plan on getting OPG.

What would you recommend for the crank pulley? Stock or 20% OD? And what size blower pully?

I DD this car so do not want to go crazy with it. I would rather have a more "reliable" and sacrifice a few HP than balls to the wall. Also it needs to be on 93 pump gas.


thanks guys!

DD on 93 3.75 would be the smallest most would recommend. 6 rib will be fine.

Now if you go e85 you'll have the fuel system and injectors needed to run a tune for it.

Thank you. In yalls experience, what kind of RWHP have yall seen with a setup like this?

I have seen guys on 93 reporting as high as low to mid 700's, and on e85 into the mid 800's. A nice "safe" high 680-700 is a reasonable expectation out of the 2.9 on a Gen2, I would think.

That compressor will make 930-1000whp if you want it to.

Don't run a 20% overdrive damper on a Whipple unless you want a 2 piece crankshaft.

Don't run more than 10-11psi/670-700whp on gasoline unless youre looking for a few lifted ringlands.

Thank you everyone. This is exactly what I'm looking for. Eventually I'll want more (sooner rather than latter)..... eventually this car will be a weekend car instead of a DD.

3.625 we’ve ran on 93 with the 2.9 and have been fine with 2015-2017. You’ll be in the 700’s.
