    I put the Riva nozzle in this past weekend with the 82 ring and I dropped 1 MPH and dropped RPM to 8560. Now with the cooler weather I think I am on the limiter with the stock 83 nozzle. 8600-8640 RPM. Waiting till it cools down more to get a winter prop.

    Gus, You should have done a top speed run this morning. Nice and cool today maybe worth 1mph. Is your 4" air intake a rear air? I have seen performance increase going from 4" front air to rear air system. Whats your rev limit 8650? Pitch down a hair and try to get real close to the limiter will give you a little.

    Sell your T-stat and plate and go with open loop cooling and plate... The only thing is you have to monitor your temp a little closer so you don't overheat or run to cold...

    I have the open loop kit on the way. Traded my 158* thermo for it. If I run it I am going to use Sno's routing meathod. I am not sold on the Riva plate yet. Havent heard too much feedback on it.

    You are correct. Duke pitched my prop and it kicks ass!! At the drags I was much more competative than I would have thought! And would reccomend him for your prop needs! The current prop 15/20 was pitched to a 15/19 with a little extra work and is perfect for my summer prop. If I stick with this setup I guess my winter prop will probably be a 15/20 pitched to about a 15/21 4 blade.
