    For those of you running external intercoolers

    At the beginning of the summer i was running 77+ shortly after that my speeds diminished. I tried everything under the sun all summer long to try and find my lost speed. I noticed my boost on my gauge was exceptionally low. Especially for running a Vortech SC impeller.

    Come to find out I was leaking boost from my stock IC blockoff plate. I was relying solely on the O ring to seal it up. When I removed the blockoff I could see where it had been leaking. I ran a bead of Right Stuff silicone on the blockoff plate and re installed it. Now my ski is running good again and boost came up nearly 1 psi

    So, if you guys are running a external intercooler and only have an O ring for the seal you may want to pull it off and also seal it up with some silicone

    See I said you were low and wouldnt run. I do not understand the grate thing on your ski seems they only work with hooked hulls and wount work with hulls that have none.

    Yea, im very pleased with what the additional boost did for me.

    I don't get the grate thing either Craig. It just blows my mind. By the way i took my hook back out of my hull during the week. Getting slight porpoising now, but i think if I bend my rideplate extension back down a little it will eliminate this.

    This seems like a good time to bring up the importance of running a strainer in your intake water line. The small water passages in the aftermarket intercoolers can get clogged very easily. This will result in lost performance that can baffle riders and be hard to diagnose.

    You are right Richard. I need to take that advice and purchase one. Anyone have a link to a good one?
