    RXP Water Routing Question

    Have a question on the water routing on my 07 RXP. Previous owner upgraded ski with an 08 style waterbox and XS type intercooler, ski has ran fine with this setup without any issues, I am changing to a Fizzle F1000 for reliability. Currently the water runs from pump, strainer, intercooler, exhaust manifold front, rear of manifold, transom dump. My question is should I install the T fittings before intercooler and after exhaust that are standard on the 08 exhaust system? I'm sure the intercooler can handle the pressure since the Chinese one did without problem, but want to make sure everything is getting enough water flow.

    i have a rxt 05 and tried to do the tee before the inter cooler with the designated dump and i had nothing but problems. i tried to drill out the restrictor from stock 9mm to 10mm to 11mm and finally 12mm and still had a problem with the exhaust overheating once i got over 6500 Rpm's. This winter I put it back closer to what stock is for an 05. my 13 RXTX AS has the tee before the innercooler which I drilled out to 3/4 inch on all sides and put a designated dump and I'll see what happens.

    Thanks for the reply, that's what I was wondering about. My current setup worked fine last year so I will just stick with the single line for now. Were you running an 08+ type exhaust on your 05 or the j-pipe setup?
