    So is this pretty much a drop-in alternative to the C5 that requires a housing mod? Looks like it makes about the same boost as the C5.

    Their C5 no longer requires any housing modification. It was completely redesigned and lightened and re-released a few months back. The C8 is the next step up from the C5. Yes boost pressure is relatively close, but the C8 will outflow the C5.

    Read the description carefully. There are some pretty aggressive claims in there. They've been getting more and more aggressive in their designs and the results their stuff puts out. Other guys are working hard on making more power too. Lots of development coming the closer we get to spring = good stuff for everyone.

    Here's the comparison between the two.

    The R&D C8 Monster Wheel Kit produces 18 plus pounds of boost pressure @ 8700-8900 rpm, 16+ @ 8500-8600 rpm. The new drop-in R&D C8 also offers superior off throttle surge over other 16-18 pound boost wheels. Less surge increases supercharger clutch reliability.

    The R&D C5 Monster Wheel Kit produces 4.5-5 pound per minute airflow gain with a solid 15-16 pounds of boost pressure @ 8400-8500 rpm, 17+ @ 8700-8850 rpm. The new drop-in R&D C5 also offers superior off throttle surge reduction over other 15-16 pound boost wheels.

    The real comparison is in the CFM numbers I'm sure. The R8 with it's longer blade design is where the extra volume will come from.

    The way things are looking there definitely won't be any boost shortages this coming season. lol

    Gotcha. Sounds like they just made the new C5 obsolete already.

    I think this wheel looks like shit. Lead weight and low boost numbers!!

    Im getting 17+ PSI @ 8600 RPM and seeing spikes of 18 psi out of my billet enginetech wheel. (ET16)

    Why would any one want this lead weight??

    I have never seen an R&D wheel perform any good and could imagine that clutches wont last long at all with this wheel thats for sure.
