I have a 2001 F550 with the 7.3
I heard or read somewhere that a wheel from a 99 7.3 was better than the wheel I have in mine. I don't think I need an expensive wicked wheel for my truck. It is a rollback tow truck. I would just like a little better performance.
Thanks

The wicked wheel 1st gen actually produces less peak boost, but if you are experiencing turbo surge or flutter, it cuts down on it quite a bit, but the compressor map on it puts a broader boost curve, more torque early which I think would help in the towing business.

This thread makes me wonder. SPX vs Wicked wheel? Same thing or different. If different which is better?

I believe the SPX is taller and lighter than a WW2, now whether or not that equates to better has yet to be substantiated. The guys that run either one seem very happy with them, that I do know lol

I had the WW gen 1in my stocck turbo before I went with the 38R and ran it with the DP tuner. In the summers I would get a pretty good amount of turbo surge, especially when towing, so I opted for the gen 1 wheel, back before any of these other designs had come out. It cured my surge problem very well, and I ran it on another stock turbo when I got my 160/30's. I would routinely see 33-35PSI out of it with the bigger sticks and then the bearing in my turbo went bad from over driving it I suspect. It certainly was out of its desired RPM at that point. But on stock sticks, it was very good, I liked the added turbo whistle it had as well.
