[200q20v] FW: [s-cars] 2Bennett 3B oil cooler upgrade

Thanks for response. Your temps were exactly what I was shooting for. I
had previously tried an RX7 cooler in front of the main rad. Had to make up
lines and relocate a part of the A/C ssytem to make enough room. While I saw
a little improvement, the tradeoff was a drop of about one half bar in oil
pressure (car normally runs almost 4 bar on the street). TheRX7 cooler also
didn't help water temps IIRC. BTW, the fenders are also vented to help air
escape. Oil changed before every track event, use Mahle or Mann filter,
Mobil 1 15-50.
The 2B install is pancake, passenger side front, right above the right air
duct. The additional ducting for the stock oil cooler comes out with the
cooler. Only the "brake" air duct remains. I am going to try to get pic and
see if I can scan in my office this week.

Mocal. You need a temp guage, find someone with an IR guage, and make sure
that you actually have oil to the cooler. If you do, the lines should
register xxtemp coming in, and xx temp coming out. Oil coolers lying down,
don't work without something to force air thru it. A fan perhaps, or some
that spare ductiing. I'm not familiar with the 2B installation location,
in left side radiator 44 chassis cars, the easiest and best location is in
front of the radiator (btdt many times, including some of my own cars). You
spend some money on the lines to get there, but the airflow location is
really good, and it has the advantage of working well at low speeds with the
rad fan running. Scar installs I've done, put the 25row in front of the
radiator as well, with the same excellent oil cooling results.
With 25 row cooler installed (I'm figuring this is what you have by your
post) on a 20vt, you should see temps at 100-110C, maxing out at about 120C
at the track ( or hard riding). If you aren't seeing this (and you aren't),
then the conclusion is, the bigger oil cooler lying down, is worse than the
stocker with ram air. IME, audi oil thermos never stick, especially if you
change your oil at all, but there's always a first time.
Bad execution of a good mod.
