    14/20 Dynafly Re-Pitch

    On a stock motor besides, d-plate and Riva Race Flame Arrestor (soon to be some of those great ported and stacked throttle bodies), what should the pitch be? I am trying to root out every possible problem as to why my RPMs are low and I figured this could be one!

    Fresh motor, broke in, heated up on the hose in the driveway to close to temp specs in the book.

    110-115 psi all the way across.

    Wait untill you get all the motor mods done first,then look at the prop.You dont want to repitch twice.

    I'm no expert, and I'm sure there are several who will chime in, but that seems kind of low, sepending on your head. Plus, I would think you need more compression to spin that big prop.

    chris,you need to get an EFI controller.I see your running the race filter. Also, bump the compression up.After the modded TB's,you should be better off.
