Nice billet wheel. Install was easy, had to tighten another turn and a half once I reached torque spec to fully seat it. Seems to spool up a bit faster and has a faint high pitch whistle at >2700 rpm. It has eliminated the surge when shifting from 3rd to OD while getting on the freeway aggressively. Have not towed with it yet but hope it performs just as well under load.

Cured my horrible turbo Surge and pulls hills super smooth now. Response and spooling is way quicker than the stock wheel. Little more whistle but nothing horrible. Thanks for all the help Clay!

I previously had the Banks compressor wheel installed & after replacing it with the Billet wheel from Riffraff, I saw an increase in boost from 21 to 24 , also it increases much quicker.

Awesome wheel! I gained an extra 8-10 lbs or boost with this, all my air is running way smoother. While not throwing a bunch of smoke. Runs clean. Highly recommend this. It sounds real good

In the middle of installing now, but realized I didn’t have a new o-ring.

Bought this to replace my old, knicked up wheel. I will say it is a major improvement. It sounds better and the truck no longer falls on its face at low RPM going up hills. Also spools up much faster.

Great upgrade while rebuilding my turbo on my 2001 7.3. Installed right on the turbo, and I am seeing right at 7psi more boost in my 80 tune on a Hydra.

Fast delivery on this, easy install, went right on and I am making almost 8 more pounds of boost.

I have used this billet compressor wheel in a number of projects over the years. It always delivers increased performance with no downsides. Expect lower EGT, more power and decreased back pressure delta.
