i have a 99 f350 7.3 6spd. its time to rebuild the turbo its got enough play that the compressor wheel can touch the housing. the wheel has been changed to the wicked wheel it looks like but the fins are all chipped up so thats gotta go too. Id like some info on the Wicked Wheel vrs the XDP X-Wheel. The fin config is different between the two so i wonder if theres a performance diff. If anyone has tried both or has some exp on the matter that would be awsome and maybe a suggestion on a completely different wheel all together.
