I have searched these forums as well as others but am not getting any recent answers. Its 2016 and I'm sure things have changed and Options and revisions have come and gone. I have the m45 with a 17%. DDM intake. 550cc injectors. Borla race cat back. Obx header. RMW dominator cam. I'm looking to get more power yet for track days. It's winter in Wisconsin which means project time. I am looking into pistons rods head and a better cam. A supercharger upgrade came to mind today and want to know if anyone has experience in the Options. I've seen Speintex Rotrex TVS. Anybfirst hand experience would be great. Also if any vendors see this post whatever info you have would be appreciated. Thank you, Mike.

 

This beast has a TVS kit from RMW, which is still in development. The supercharger itself is a TVS 900.

 

Honestly, for track days I'd stick with the M45, while I love my Sprintex, I wouldn't suggest it for the track, there were always tuning and other issues with the Rotrex, plus there was never an actual kit. And while the TVS looks promising, it's too early to tell and again no real "kit" that you can just purchase and install.

 

We've had really good response to this baby:
