Jason, your reference to the 38 Cig, was that Gary's by chance? I recently picked up the PSI's, intercoolers and fuel system off Gary's motors. Just curious.

Yep, those were off of Gary's (RMPRam's) 38 cig. What boat are you putting them on? If I remember right, they have a custom built Carl Foltz intake with a slot for the cooler. When Gary got them, we custom made some copper tube and fin cores for it. They worked well and lasted. The previous alum cores were sprinklers.

Here are some pics of the boat that had them before Gary got them. At the time, I think this boat owned the kilo record at 134, but would run into the 140's, which was stellar for 1998.

The carbs side by side on the front of the PSI impresses me as much as the polish job. Not many builders run them that way, but should be much superior to an in-line set up. Screw blowers like to be feed from the end of the rotors, and this is what you are doing with both carbs up front.

Talk to Patrick at Pro-Systems regarding the possible use of their SV1 carbs. They are reported to have great driveability and have tremendous flow in the larger versions.

Jason, so the coolers in this package should be fine? I know Gary thought they were. What is the deal with needing a "deflector plate" beneath the PSI?

I would think you should be fine. Your particular cores had copper tubes, not cupro nickel. Keep in mind, they are 10yrs old. Just make sure you pressure check them.

Regarding the deflector plate underneath the PSI, that has been a longstanding debate. Alot of people just use the the PSI adapter plate and the channels built into the bottom side of the blower, which is what your setup has (your adapter plate was welded to the top of your manifold). It also depends on how fast you spin the blower.

You should let me build a fuel injection system for it. This is one that I'm working on now.
