    Got the impeller back from Impros

    It was a 12/18.5. They cleaned it up welded the diameter, got rid of the cavitation burns, and made it a 12/19. This combined with a new impeller housing, hopefully will get me to 70.

    A 12/18 would have had me real close if not on the limiter. I have the stock CDI. I usually turned 6950-7010 with the 12/18.5.

    I would need to a nasty motor mixing race gas like Big Raider to turn that high. He has a nasty Raider.

    Im sure you can turn 7100-7200 rpm with your porting.(on 93 octane)
    I turn 7000 rpm with no porting.
    What octane do you run at 7000 rpm I can run 87 but usually run 89

    I ran as high as 7550-7560 with the pipes I think the pipes like 7400-7500 rpm I think the single pipe likes 7000-7200 rpm.
    I could be wrong but I think im right.
    Im telling you over 7500 rpm was awesome but I thought I was going to blow up the whole time I was on it.
    Total rush mixed with race gas.

    Just a thought
