Dewitts left side EOC plumbing??
I just picked up a dewitts radiator with a left side engine oil cooler for my C5Z and I am wondering what the popular way to plumb it in is? The car is a street/autoX car and I went with an integrated setup to get a bit more cooling knowing I'm leaving some cooling potential on the table but just to help keep temps reasonable. I see dewitts sells the modified C6 setup but is that the best route? Is the by pass really necessary? I was planning on running -10 AN lines to the cooler because that seems to be how all the coolers (stand alone or integrated) are plumbed, is that the best choice?

Tom Dewitt initiated some forum post several years ago talking about possible reductions in oil pressure at elevated RPMs when he started selling the C-6 set-up you speak of. Quite frankly I've never seen the need for it in either one of the cars I had this system on. I've participated in dozens of autocrosses and several HPDEs with this set up and never experience any lack of oiling or oil pressure reduction symptoms (I use Mobil 1 5W30).
If you choose to go this route I recommed you keep the stock cooling system thermostat, othewise the engine will run too cool. If you drive the car on the street in cool ambient temps with this set-up you will have to partially block the radiator's air flow to ensure your coolant and oil operating temperatures are high enough.

Love my Dewitt's but here was my install experience with the modded C6 EOC version on my '02.

Thanks for the input guys. I was leaning towards the AN lines for a few reasons, ease of install being one of them. Ipuig any idea what length lines you used and what angle fittings you used where? I am thinking of building my own lines as well, I'd like black fittings instead of the red/blue AN stuff.

If you've never assembled hoses before you may want to consider purchasing a kit or going to an industrial hose supplier/distributor and have them build them for you.
BTW, if you have headers I recommend you remove the driver side header before you start the installation.

AN designates the fitting type (37 deg. flare), and sizing method (-2 through -32) color or material composition have nothing to do with this designation. Which fittings you use will be determined by the route your oil lines will take. I believe both of my hoses have 90 degree fittings on the radiator end and straight fittings on the LPE oil adapter end.
