    Anyone using the H1 ?

    The competition back here in Trinidad just bought an RXT-X with a turbo system. The GT3076R turbo. I am a little concerned so I want to step up my game as well. I was thinking about the RIVA H1 supercharger, but have a few questions about my new setup. First to start up my engine is going to be shipped to RIVA to get the full internals done plus aftermarket valves, Gen3 S/C shaft and dampener, with crank balanced. I am thinking about getting the H1 at the same time. What fuel is recommended with this wheel. I was thinking about running two maps if I had to. One on premium pump gas for weekend rides and one probably with a mix. I am not an all out guy and still want some sort of reliability. What are the suggested RPM's to run this wheel at, and is this the best move or should I get the ET 18 psi supercharger or even stick with the E1. Any advice appreciated. Thank You.
    ALso take into consideration I'm not the best tuner and this is going to be my first time tuning an engine making this much power

    H1 is a great wheel.

    Im sure Riva will be able to send you a map for your Vipec for it. The mid to top end pull is unreal!

    I am currently running 77mph with my current setup. I know it's low but so are my RPM's. My RPM's are at 78-900. My prop has never been touched and with school I've never been able to start tuning AFR's as yet.

    I don't know if they follow the IJSBA rules in TT, but the H1 would put you in OPEN Class because it is a new housing. Other than the holeshot and the straight away...the E1 would be fine (for LIMITED Class). If your in Open Class, you might want that H1.

    No we don't. All supercharged skis are split up into two classes. Modified and unmodified. So basically in the modifies class anything goes. So I'm just trying to stay ahead of the game
