    How to check for pump/shoe/etc. leaks (that could affect performance)???

    Hey everyone,

    So, I'm wondering about my speeds with my mods, and was reading on another thread about someone that gained 3mph after finding some leaks in the "pump shoe seal" that allowed air to enter the pump. Some others asked in that thread how to test for this, but nobody responded, so...

    Are there tell-tale signs of a leaky pump seal, poorly sealed ride plate/pump shoe/pump/grate/etc., or a way to "test"?

    Mike you would have serious cavation if your pump was leaking air. You can gain alot of holeshot by installing solid front motor mount and aftermarket seal for your driveshaft, doing away with the carbon seal/boot that OEM includes.

    So, after a solid mount and dumping the carbon seal and boot I would have to re-align the motor correct? Something that a fairly intelligent person can do without taking it to a dealer (ie. no special tools required)?

    Yes you would need to re-align the driveshaft but it does require special tools. Here is a great write up from Jerry on everything involved to align it with pics.

    don't you have to machine the driveshaft for the seal mod?
