    4 inch Rear Intake

    Just swapped from the Riva 3 inch front mount air intake to this. It might take in a bit warmer air, but the volume increase should more than make up for it. Besides I've got plenty of hull ventilation and the rate at which these super chargers suck, the hulls air volume is probably replaced every few seconds.

    Thats the theory anyway!

    Try sucking down through a drinking straw, then try sucking through the same length of say, a garden hose, Your lung capacity hasn't changed, but your ability to draw air in has improved dramatically!

    Imagine the inlet of the SC is your mouth, by increasing the size of the pipe work leading to it you increase the breathing ability of the SC! The easier the flow of air to the SC, the greater the ability it has of processing it. The shorter the intake the less restriction there is to the flow of new air.

    The down side of course is that the intake of air now comes from a warmer part of the hull.

    No need for a catch can! I don,t like them anyway. Here is a picture of the breather fitted into the intake at the elbow just before the SC.

    Another pic of the the biggest change you need to make when doing this mod. The 4 inch elbow hits the exhaust temp sensor in its stock position. I had to cut the waterbox exhaust outlet pipe off and turn it 90 and weld it back on, easy mod.

    What is that you did to the drive shaft seal? A one-piece bearing seal?

    It is 4 inch ducting used to transport saw dust away from wood working machines and the like. A 4 inch elbow of thin wall ali tube would have been my first choice, but to hard to find. The fitting is a 5/8 air hose type fitting bolted through the elbow with a lock nut on the inside. All sourced locally.
