[s-cars] heat exchanger instead of the oil cooler

VW's have been using water/oil heat exchangers for years, including vr6=all.
Water/oil heat exchangers aren't as effiecient as air/oil exchangers/coolers.
 Fredric, get a bigger oil cooler installed.  I know for a fact you can put a
25row standard -10 oil cooler in front of the radiator.  I also know that
this should lower your oil temps massively, even during track sessions.  On a
full race motor I built in my shop (26psi 400dyno HP), the 25 row would put
up temps below 130c during the hottest of track days (100F track temps), and
the oil temps would fall back to 100c before the car got back to the paddock
parking.

Going water/oil is going to reduce the effectiveness of both temps.

Ted,

You are correct, I am talking about water to oil cooler heat exchanger. The
reason of this approach is the fact that the water temperature never goes
more than 90 degrees celsius on track
Before installing such system, I am going put louvers on the left front
wheel liner. Possibly go for a bigger oil cooler (Porsche for exemple) or
have two stock Audi oil coolers. Fan Forced airflow can be an option as
well.

I will keep you posted.

Frederic
