    I need more speed, help!

    I Finally got a GPRXP. The best I could get out of it was 88 mph. Today I installed a LC-1 and got the AFR right between 11.5 and 12.2 at wot. and also shimed the ride plate .045 in the front. All I could get was 88.6. It was 92 degrees with 75% humidity. I was hoping for more speed. So any sugestions on what I could do to get more out of it. It has a RUDE 2, riva ecu, ferera valves, all the other goodies. I'm spinning a 16/22 at 8600rpm . HELP me please.

    Thanks, MONGO

    Mongo... the speed is there in the hull, it just needs to be unlocked.

    IMO get used to riding the GPR first, and get thru the summer. This winter will bring more speed 4 sure.

    If you just cant wait, then give me a call and we can get you more.

    Yes it has the ss 800 grate. I got it from Arny, Dome. Hey WFO I'm pretty happy with it but I know there is more there and I know you are the man for that. Maybe when Rich gets his prop tuned in you could take a look at mine and work your magic, please please please LOL. The steering is pretty heavy maybe that is just a characteristic of the conversions IDK. Shimming the ride plate seemed to help a little but I don't know for sure what I'm doing when it comes to tuning the hull.
