    Exclamation American Turbine Hi-Helix Impellers- Q's

    I have heard a little info about these guys. What are the pro's and con's? i have info but lost it somewhere.
    I have heard that they "Bite" very hard. Is this true?

    Im going to a serious HP deal and need something that will take a serious load.


    Thanks in advance Spitta "Mike"

    I've been wondering the same for a while. It would be nice to hear from someone who switched. Seems like I remember that an HH, AA, would be taller than a berk AA more like AAA.

    Yes, We have the HP/IMP Cuts pretty much all charted for the H-Helix impellers now. Send me your engine dyno sheets and I'll match you up to one. They turn lower RPM for what they do, but they DO NOT follow the same curve all the way through. In other words, an AAA Berkeley might equal a Hi-Helix A, but the spread between a C berkeley to Hi-Helix will not be the same number of cuts apart.

    And YES, they bite very hard, especially after we work the leading edges of the blades.

    I have one in my pump but the boat never leaves the trailer so I can't comment on performance. However, I can say it is nice and shiny.

    If you did drive it, you'd be the first ever in the driver's seat. That gives me a great idea, I should just take out the driver's seat. It only gets in the way and with the weight savings, I may get better fuel mileage in the truck towing it from lake to lake. I'm surprised Pedro didn't think of this great idea first. Maybe I'll post a video of me removing the driver's seat.

    I got the GPS locked and loaded, I went for a ride on my rice rocket today and racked it up to 169 MPH.

    I am going to use those GPS numbers for my boat because it only runs on the trailer. I'll take a picture of the GPS reading 169 on the dash of the boat tomorrow.
