This is a trick that Rob Golden at Pineapple racing turned me on

to,

he did dyno testing and found 15 degree drop in oil temp measured
before the cooler by doing this, you drill out the plug in the side
of the front housing and tap it to take the oil strait out of the

oil

pump to eliminate all the small oil passages and 90 degree bends in
the front cover, then  you plug the outlet on the front cover, this
way you can still use the injector if you wish and the pressure
relief valve functions as normal, Also do away with the banjo on the
return line as it is very restrictive.<<

Yes, it works very well and there is one thing to be careful of.  The
front [end-house] plate is fairly thin in the area of the new outlet.  If you
overtighten the fitting into the plate it'll crack the plate.  Rob'll
tell you how to best do this.  Fixing a cracked plate is a bitch!  You
have to remove the front cover and grind/weld the cast iron (not

easy).

However, the resultant flow increase is phenomenal!  You can run 3
window mains without worrying about oil supply at idle.  Those banjo
bolts suck for main oil lines on a modded engine!

I have this on my '90 GXL and would never go back unless I had to.
