First off if you are unlucky to have the early 99 7.3l like me your in for a job.... I thought this replacement was going to go real easy from what I had seen in videos but if you have the early 99, the bolt pattern is different on the compressor. We have a 4 bolt compressor vs the 5 bolt. You ask why that matters, well the 4 bolt has the bolts at the sides and top , bottom. You can't get to the bottom one without pulling the turbo off the pedistal. A 20 minute job took about 2 hours. With that said, I noticed a quicker spool of the turbo, more lower end power and around 4 more psi on the boost. Definitely an improvement over the stock wheel.

Almost too pretty to install but I went ahead and put it on my turbo anyway and oh baby!This thing spools faster, sounds meaner and moves more air than the stock wheel. What's not to like about that? Between this and the EBPV delete I did, I picked up 3-4 PSI at 3000 RPM with this wheel over the stock one. What's not to like!?

I am coming from my last truck having a wicked wheel. I think this wheel blows it out of the water and I feel that my truck spools up faster and is much louder. It sounds great and was one of my first mods done.

Cant say enough good things about this thing, wasnt sure if it would be worth the money but it is. Quite a bit more mid range power and and sounds cooler if your into the turbo whistle thing. I would strongly recommend this to anyone with a stroke.

Clay twisted my arm a bit, and I ended up purchasing this wheel in lieu of the anti-surge wheel (thanks Clay). I paired this wheel with the IH up pipe kit and the banks wastegate actuator. I've gotta say that I am very pleased. I've just gotten the vehicle back together and have only taken it for a short drive. Throttle response is crisp, turbo spool occurs at a much lower RPM, solid power across the rpm band, and the "surge" is gone. Can't wait to see wow the truck performs when towing. Thank you Riffraff.

Picked one up, along with a ebpv delete, intake and rebuild kit. Truck spools much quicker, less smoke, and picked up quite a bit of power as well. Sounds and performs great!

My 2001 7.3 has just under 300k on it.. it's got a intake and mild programmer (nothing special) and 4" turbo back exhaust with not muffler.. I pull a 22ft boat and a 21ft trailer with a 40hp JD tractor all the time.. and this wheel made a great deal of difference on top end spool (no more turbo surge) spools a great deal better than the stock wheel while loaded.. don't really concern myself with watching fuel mileage so not sure if it will make a difference there. As far as sound goes it don't seem much different at idle and low rpm take off than my stock wheel... BUT at high rpms sounds great has Slight whistle I can hear in the cab but not like the WW on my buddies truck which really gets annoying on long interstate trips pulling a load.. over all I'm extremely happy with the product all the way around and it wasn't at all hard to install myself..

Big thanks to riffraff diesel products!!!

Good product, good quality

Was machined very well and looked to me good quality. Noticeable proformance increase, not much boost loss. Didn't even really know I was getting surge until I installed this wheel and felt the difference from stock. Very pleased with purchase.
