Riffraff Diesel Billet Compressor Wheel 94-03
We are now offering our 2nd Generation performance billet compressor wheels for the 94-03 7.3L Powerstrokes. This wheel provides more than just anti-surge like the standard Borg Warner aka Whistlin' Wheel, Anti-Surge Wheel, Banks Wheel and other 5/5 blade compressor wheels. Because of its lighter mass it spools faster, while providing more CFM flow and boost pressure. We usually see a 5-7 PSI gain in boost, as well as less smoke, better drivability and quicker response. By incorporating new leading edge technology, metallurgy, and the new 4/4 blade design we are seeing an average of 17.4 hp and 38.7tq gain on stock injectors with just a swap of the wheel. We recommend balancing the rotating assembly if available, though the wheel is already dual plane balanced.
Fitment: 1994-2003 stock TP38/GTP38 including van turbo

What a difference!
Can't say enough about how much this wheel changed my truck. More response, more boost, everything is better. Highly recommend it.

Better throttle response and mid range
My truck had a wicked wheel 1 installed previously. It had good low end torque but fell flat in the mid and top rom range. After installing the riff raff impeller i still had good low end but a much more pronounced mid to top end pull. Spools up faster and peddle feel is less mushy. Its the best mod for the money in my book. Happy with the quality and performance.

My truck sounds like a Jet
After about 8 lbs of boost my truck now sounds like a jet afterburner. Normal whistle under 8ish lbs. Smoother spool. Hard to tell if it spooled quicker because I did this at the same time as up-pipes and the truck overall runs a lot different now.
Also Clay has THE BEST customer service. My wheel wouldn't spin on the turbo-shaft by hand. I emailed the customer support link and within 5 minutes on a Saturday night Clay responded telling me to heat up the center of the wheel with a torch (I used a lighter) and it worked like a charm! -

Stopped surge and increased boost on my '99.5 7.3
I have 218k miles on my '99 F350. Turbo surge was getting really bad. Especially when up-shifting. While towing uphill the turbo would surge constantly.
It took me about 2 hours to install this wheel, without removing the turbo. Not a difficult job, just clumsy to reach some of the bolts. Turbo surge is gone. Low-end power feels better. I get more boost all around. There's a bit of a whistle under hard acceleration and while towing, but it's not irritating. I like it. My wife says it kind of sounds like a jet engine.
My stock wheel was 125 grams. The RiffRaff wheel is 100g. Doesn't sound like much, but I think that difference does help the turbo spool up faster.
All around this was a great upgrade and well worth the investment. Now I need a performance chip to really open things up. -
great improvement over stock
just installed this wheel along with a new turbo cartrige, frx, cac boot kit, & ocr from RiffRaff, after getting the air worked out of my fuel and oil lines i can tell a big improvement, builds up boost faster, has more power, no more turbo surge, i expected the whistle to be a little louder but as far as the performance its awesome, thanks Clay for the great products and always answering any questions

Great product
Great wheel,easy install and could tell a immediate difference from the stock wheel and not as load of a whistle as expected.
