    carbon/kevlar mustang please help.

    PATPRIMMER: You will get mould shrinkage, so the mould ends up smaller than the pattern and the part will end up smaller than the mould. how much smaller? is this uniform shrinkage, or does it have to do with the orientation of the materials? if the shrinkage is uniform enough, shrinkage...

    Boost leak in turbo? Any suggestions?

    WELL, JUST A LITTLE INPUT, WHEN I NEED TO PRESSURE TEST A COOLANT SYSTEM, EXHAUST SYSTEM, OR INTAKE, A SIMPLE ADAPTER CAN BE MADE FROM AN APROPRIATELY SIZED INNER-TUBE.

    constantly variable length runner intake. interesting.

    the ford 3.8 did have an intake with two seperate fixed length paths, so did many other manufacturers. i am not sure about the f1 cars, but the yamaha's system, though revolutionsry, is not exactly what i am describing. it kind of switches between two fixed lengths as well, also, i cant see how...

    constantly variable length runner intake. interesting.

    constantly variable length intake runners... just bouncing ideas around at this point, as i am in no position to begin production on anything at this point, though i may build several prototype units to fool around with. my idea is this... individual throttle body setup with constantly...
