    Ordered my et127. Few questions

    So I ordered my wheel, and also 42lb Bosch injectors, and a 14/19r prop. What should i expect from this setup?? Also my sc was just rebuit so I plan on just swapping wheels. I should just check the slip correct?

    Just follow the instructions from Engine Tech on torque specs. If not you'll want slip moment approx. 12 lbs. Check after 10 hours and re tighten if necessary.I'm doing the same set-up for my buddies ski and on an RXT attempt to get as close to 8050 rpms with stock ecu and you should be around 72 mph as long as you have everything set-up correctly and there are no other speed loss issues due to drag etc. If you have an RXP I had a similar set up years ago with an X-charger and should be around 74 with stock everything. If you put a Riva ride plate can van get close to 77.....

    You will or may need to repitch prop to hold back rpm ...

    Approx. 1 mm is equal to approx. 100-150 rpm.......Start with the trailing edge.

    I still believe that a reflash to 8350rpm and repitch will be the best . Better map and extra rpm will work out great

    Stock ecu is fine.
    It's all you need it's a simple wheel. I'd prefer a stock ecu running this wheel than a reflash that is offered these days. This charger runs fine on a stock ecu and is safe!
