    2012 rxp-x cooling water to exhuast and intercooler RESTRICTED by FACTORY

    Okay guys i am changing my prop to 15/20R and i noticed a water cooling restricter washer that definitely restricts water to the intercooler and exhuast.

    I bet if i widened up this washer hole i would get better cooling for my intercooler....but would this cool the exhaust too much?

    I could always put a restricter on the exhaust side to limit flow and let the FULL cool water flow to the intercooler.

    I bet this is almost like increasing the intercooler size due to more flow!

    OPINIONS PLEASE!!

    You will have too much water and flood your water box at idle. On the RXP's when converting to an external IC you can drill the washer out a bit. The RXP-x's already have a larger restriction washer than a RXP.

    I would leave it alone as if you make it bigger or widen it it could possibly cause your IC to leak do to the increased pressure....

    +1 to all the above.... The Green restricter is the biggest one.. and the yellow is the smallest.. no need to change it.

    You have plenty of pressure with it the way it is..i also run a T inline with mine, one line to the IC,the other to the HX and exhaust and have had no issues at all with temps or volumn...
