    et 137 injector and prop pitching

    hey guys i am on the verge of pulling the trigger on the new et137 4mm. so my question for the guys that are running these with 42lb injectors what are you running for base fuel pressure. with the x charger and 42s i have the base set to 50psi and running the boost line. i am thinking to start out at 55 to be on the safe side. my next question is with the 137 do you think i should step up to the 15/22 or just pitch the crap out of my prop?
    thanks

    I'm running an Et137, with 48# injectors with base pressure about 42. I'm also running a untouched 15/22 prop and I see 7850 rpm over 90 degrees but when in the lower 80's I see 8100rpm.

    Start at 58lbs.... As far as pitch ride it and see where your rpms are at then u can get a idea...you want to be at 8100.... Good luck you will love that charger.

    +1. 58lbs is a good starting point and go from there. Ride, pitch, adjust and then do it again. LOL.
