    Et127 with 42# reliablity

    So on my 05 rxp I'm installing the new wheel and injectors and I already have fizzle intercooler. My question is how reliable is this set up. I do like to go fast but I also like to explore and cruise around will this combo cause me any problems

    my 05 ecu did not like any boost over 11psi
    it would go to 100% ds
    that in its self is bad enough but that also sent my cmd crazy

    ET127 on stock ECU with 42s will run fine....might be a lil rich down low but i doubt itll give you any problems. Ask kevin (green bullet) he had the 127 and 42s and is always tellin me he wishes he still had it because it was super reliable. I ran the riva impeller for my 127charger on my 09RXP with 42s all day before i stepped it up and went ET137.

    I have put about 15 hours on mine since installing the wheel and 42's over the winter, so far so good just gas and go.

    You'll run fine with that wheel but if you have an ex IC it will help as well

    i ran mine and saw 11-12 lb boost at 8100. I also have the charger tight

    this setup works real well and if more reliable than your stock charger because the wheel itself is very light so less wear and tear on charger internals. I beat mine up real well for a summer and the slip didn't move one bit

    I done many set ups of the ET 127 with 42 inj on stock ECU and best bang and very very reliable set up ...

    You may need to change prop as u may be all over the rev limiter ...

    It is a great setup I am running that set up on my 09 gtx with the fizzle intercooler if you can afford the intercooler I would go head and get it also
