    ET137 + 4 Will I need Fuel Pressure or anything else?

    Hi Guys,
    I got a good deal and will buying a ET-137 for my PX, the only thing I have done to the Ski is a 8375 Flash turning around 8200 with stock prop. If I get this wheel will anything else need to be added? I am not going crazy witht he ski after that it will be a IC and Prop and call it a day 74-75 is more that enough.

    Thanks in advance.

    your ski is likely going to go faster than 74-75 with that wheel and an intercooler by a good bit, to be safe i would do a regulator and injectors along with a new tune. also you will need a prop with that wheel as well to keep the rpm in check.

    I want to avoid adding injectors/fuel, if that will be required then I think I wont do it. I still have 1.5 years of warranty that I don't want to void.

    You might be able to prop it down enough to keep the rpm and boost in check and maybe avoid the injectors/regulator but then that really defeats the purpose of the wheel in my opinion. maybe some others can chime in.

    The stock wheel is capable of 80+ ask Gus or even Branden! The 137+4 is for the big power so injectors/logging is a must imo.

    op if all you want is 74-75 i would do this. Flash which you already have, r and d intake grate, intake and a 14/18 prop, and that alone will get you to 74-75. That way you wont have to mess with removing the flame arrestor and intercooler or any type of fueling upgrades. If you want faster later, add the intercooler and remove the arrestor and a couple other things and that can take you to upper 70s, even 80 if the conditions are right. like vxrslayer said, the stock intercooler and blower wheel can support over 80. 80+ you will have to either do a blower wheel or crack into the motor, or go open loop and have jim do a plate for you.

    75 isn't enough for sure lol once you feel that pull and sound you will be hooked. But yes a fuel pressure regulator and injectors will be needed as well as a tune for your Ecu. BOOM happens fast without a proper tune and a way to monitor Air/fuel. Welcome to the next step!

    Branden, why a 14/18? wouldn't a 15/20 give me room to grow
