    Aftermarket Intercooler ???'s

    This may have already been asked, but....

    Has anyone tried utilizing both intercoolers?

    As in, T the supply line to run to both interoolers and simply dead end the return line to outside the boat (one will have to go to the exhaust).

    If the stock intercooler is there and it's downstream of the blower, why wouldn't it be smart to utilize it?

    to much restriction. I have found out that the stock IC does do something. I also have had a RIVA IC in the ski as well, and that performed great for where I ride. keeping the stock IC in the manifold while using an aftermarket IC would def kill some boost... I`m sure Shibbs/Jerry could get more technical on this...PR...

    Some really good info on the thread below

    "The intercooler in the Stage 2 kit is an external intercooler and makes a ton more power than that of the stock intercooler which is mounted in the intake manifold. The stock intercooler is removed and then blocked off with a billet block off plug that is provided in the kit. It's also worth mentioning that the stock intercooler is extremely restrictive. My testing has shown a 1 psi increase in boost when going from the stock intercooler to the external intercooler."
