remove mfi cam drive?
I have a pair of rsr sprint cams that are for mfi, i don't plan on running mfi ever so what do i do about the end extension on the cam? can it be machined off? should i leave it and add the mfi seal on my came tower? use it for a sportomatic pump for a trans cooler? any ideas?
thanks!

If those are factory RSR sprint cams, I would keep the cams intact and simply install the seal in your cam housing.

Here's what you need to properly seal the cam.

that looks like a nice setup Henry, what about my sportomatic pump as a trans cooler pump idea? i seem to remember that factory 914-6 race cars did this.

The best way to run the Sporto pump is to remove the flange, drill two 6 mm holes 10 mm off center and install two 6 mm allen screws. The allen screws will engage the pin on the pump. This requires no additional bracket, you just bolt the pump to the cam tower with 3 long 6 mm bolts. Don't forget to drill oil return holes in the cam bearing journal to allow oil pressure from the journal to return into the engine instead of pressurizing the pump.
