and here are some pics of the oil pump mod:
this is where the oil is routed back into the mail oil galley.
these two fittings are connected through -10 lines and a system1 oil filter so that we can monitor debris in the oil easily.
you can see how many angles and restrictive passages are eliminated. this doesn't even take into account the several 90s within the oil filter housing.
-10 comes off at an angle to avoid the frame and the crank dampener. getting the line on this fitting is a pain... we put a small clearance in the frame rail to make it easier, but it is still the weak link for this mod.
a little internal port work on the passages.
in 2 1/2 years no bearing failures, and we run ALOT of clearance. think V8s.
