I recently purchased a 951 88 car with 69k on the clock. its not a full track car but the car has received numerous modifications for track use. the car is equipped with a front mount Mocal oil cooler but at some point it was damaged by the PO. it looks to me like at some point the PO went off track into the gravel and bent the ends of the feed lines.
long story short, the mocal oil cooler is 11' x 6.5 x 2 inch core and hangs down pretty low on the car. it looks very similar to the KISS model sold by LR and others.
the lines on this set up are pretty weird. it looks like the PO used the stock oil cooler lines and added 2 lines to the sockers with AN fittings to adapt to the mocal core. its not apart yet so I 'm not sure about all the fittings. the lines look shorter compared to the pics LR has on line. the core is not leaking yet but it is pretty bent and i'm worried that if i go off i'll crack the cooler. the lines ARE leaking slightly.
i'm also going to add the 52mm vdo temp gauge out of my old car but i have no idea where to put it. I cant believe we dont have a temp gauge stock wtf!
if possible i would like to ask you guys to post pics of home brew oil coolers because I've not found anything online that I like for a decent price. I want to go large enough to track in 100 deg heat and not worry about oil temps but I dont want to hurt air flow to the rad and IC
I'm thinking about a shorter but longer core and going with side lines, not lines that stick out of the bottom. perhaps i should go thicker? 2inch seems like the standard
thoughts? pics ? ideas?

david, thanks for the info.
can anyone expain why eyal 951 said that that a cooler port down install is bad ( see pic in link http://forums.rennlist.com/rennforum...ighlight=Mocal ) ? this is how my cooler is mounted. I would think that once fluid dynamics come into play the oil will flow fine in pretty much any direction assuming overall volumetric pressure exceeds the resistance of the cooler... not that i know the first thing about fluid dynamics.

If the oil's velocity is low enough (I have no idea what it is) I suppose its possible for air to be trapped in the cooler. I would imagine this would be more of a problem with a plate style cooler vs a multi pass.
Draw backs:
-slight reduction of cooling efficiency (in both cases I doubt the air pockets would be in the fin pack)
-air bubbles being sent to the bearings, instead of oil. (this would probably happen at high rpm when the oil velocity increases and can carry away any air pockets that might have built up).

ok, the set up on my car is a little different and i did not realize this was atypical. the stocker was removed and replaced with the mocal, not used in tandom.
so with a duel cooler set up, does one route the cooled line all the way back around on the pass side or feed it back through the driver side?
a few more pics of this type of set up would be helpfull
