    rr sc impeller

    what kind of gains did everyone see and is it save with an 4 in intake and stock ecu? also what prop to use with stock intercooler with this set up?

    Some will tell you this setup isnt safe. I know of 4 Rxps running rr sc and 4" intake using the stock ecu with no problems to date. FYI, these are endurance racing RXPs. The 06 rxp is running around 78 mph the 04 is running at 76 mph. I dont think you will see this type of gain with the stock intercooler.

    4" intake, riva grate, wedge, out of the box solas 14/19, skegs, regular opas block offs, and rr sc imp, stock oem ecu, stock ic, and stock injectors..74.8 with a little more tuning 75+ would be very easy.

    Mike, those are awesome numbers for your mods. Did you ever try running it with the 42# injectors? Im curious to know the difference.

    If you guys are gonna do that mod it would be in you best interest to install the Heavy Duty Valve kit or find out he hard way like we did. We dropped a valve at 8500 and it wasnt pretty.

    Jo Jo- I think he is running a stock ecu, I know we would'nt get the rr wheels for potential, but it's an improvement over stock. Through Hulk's teachings I think we would not have this issue with a stock ecu.

    This setup is being proven safe with stock ecu, injectors and valve trane.
