With my tuner, I was getting too much boost under heavy loads at low engine speeds with he stock wheel on my 01 7.3. This caused me to have to back off the throttle and loose momentum pulling hills.

Replaced my stock wheel with this one and problem solved. Seems to spool faster now and I still get full boost at the higher RPMs. So far I am very happy with it, but haven’t towed heavy with it yet. Not expecting any more surge problems though.

Direct replacement wheel for factory turbo. Haven’t drove this one with a load yet to see if it surges but others I have done in the past worked. Packaging was a little poor quality.

Easy to install boost up quicker not sure yet if its for the better

Performed better than expected. Gained more boost, response and most importantly turbo surge is gone. Another great product by Riff Raff.

Install was a breeze. No more surge. Not that loud. Highly recommend for turbo surge. Cheapest price you will find. Get all my stuff from here.

I own a 99 f250 superduty crew 4x4 with a 7.3 with 423,000 miles. I bought this wheel to replace the old wheel that came with my truck wich was a wicked wheel. . The differencr is night and day. My truck woke right up, surge is gone spools up faster, more power when i need it and fuel mileage is better. I run a four inch diamond eye turbo back exhaust, a k&n air filter round RD 1460 with built intake box, banks big head turbo actuator. I do alot of towing and hauling. And this wheel was excellent.
I highly recommend this wheel if your after a simple upgrade thats cost effective. Very pleased with this compressor wheel.

I don't tow, and was hoping for a Wicked Wheel experience for a cheaper price. This didn't work for me. My stock wheel would build pressure SO much quicker, and this one, not so much. But if you tow, it might be the ticket for you. I was looking for stand alone performance, and I learned my lesson. Not the product's fault, but mine.

Great wheel for the price! Definitely noticed a difference in 0-60! Spools faster! Although I did lose some whistle with it! I still recommend it over stock!!! Good product!

It was recommended to me to replace my compressor wheel while I was doing the orings and hpop lines. It is a definately improvement over the stock wheel and gives you the consis tent power you would expect. Easy install and a nice little whine!
