    Whats a better 15lb boost wheel the ET high boost 15.5 or the new R&D C5?

    Im looking to upgrade from my R&D C3 to one of the 15 lb boost wheels and ive been looking at the ET high boost 15.5 & the new R&D C5 that does not require the supercharger housing to be bored. Both wheels give about 15 lbs of boost at 8400rpm and that's just where I want to be. Is there any advantage/disadvantage of either one? Some current supporting mods that have to do with the SC are: 2013 clutch, R&D SC shaft, water cooled SC housing, type 3 intercooler. My fuel system is still the stock fuel pump and stock injectors and I will order the R&D RRFPR when I order the wheel. My ignition is the R3 reflash without a powershot.

    Et low boost wheel. It's lighter and should reduce load on your clutch.

    You're gonna hear a lot of cheerleading for the ET wheel, but take it with a grain of salt. I can almost guarantee you no one chiming in has tested both back to back. Matter of fact, there's only one person I know of on the forum who has the new C5. I've haven't run either one but have run both the C3 & ET low boost. My opinion is the R&D wheels hit much harder in the midrange because the bigger diameter design moves more cfm's & builds boost faster, while the ET makes a little more peak boost. I never tested them back to back & also changed my prop setup at the same time I swapped wheels which could be partly to blame for the more sluggish midrange. Just my seat of the pants opinion. For the type of riding I do I prefer acceleration over top speed, so the C3 might be going back in mine.

    I think all their big boost wheels(C19, C20X, C24) are billet. The pic of the C5 on their site looks like it's cast, but they claim the new one is much lighter due to the 8 blade design.
