    no so sure the numbers that you posted for me are accurate and legit... but regardless, your info on Jeff (o5limited) is a bit skewed

    Jeff runs 72.1 mph with NO ECUS.

    73.1 on my GTX @ only 8150 with the Solas 15/20....

    But that's it for me for now....Just came back in from working on yanking the motor. (Finally got the kahoonahs to do it) Drained the oil, drained the coolant, removed the thermostat, drive shaft and s/c out along with the plumbing, battery out, and ECU out. Next step, disconnecting the electrical along with a few other things, lifting the engine and sending it bye bye....

    Hopefully I'll join this club next week when Jerry sends back the re-pitched Solas. I did the ride plate and intake grate hole filling too

    Bro, you can do 70 MPH with the stock prop in your moded RXT, 2 weeks ago a buddie of mine with a moded 04' GTX did a 70 MPH speed run in 90 + deg air with my Gps, he is using a stock RXT ECU, vortech SC imp, home made ext IC, Riva air intake, Riva grate, Riva rear exhaust and a oem RXT/RXP pump with a stock RXT prop.

    Do you know what the pitch is on his stock prop ? I thought the stock prop was a dog compared to the acceleration of the solas.
