    Water restrictor for exhaust and innercooler

    Anyone know the size difference between the 215 models and the 255 models? Going to have my pump off tomorrow and was going to drill mine out...

    The yellow for the 215 is 8mm, and I believe the green 255 is 9mm. I run fine drilled-out at 10mm, but have a very large intercooler, and pissers out dual exhaust...

    Don't drill it out too much. If the exit restricts, a larger intake opening will increase pressure in the system and may cause the line to pop loose. I use washers with different diameter openings... I'm speaking from experience.
    Be careful!

    I wouldn't enlarge it unless your planning on adding a tee and an extra outlet
