Have seen a few cars with front mounted oil coolers and just wondered if the trouble and extra hose is worth it?

Mounted by the front beam area.

I have seen scoops made also to scoop in clean fresh air through the cooler.

I am not worried about the time to install or the money for "extras".

Does it make the engine/oil run cooler?

That is my goal!

Enjoy your feedback?

A scoop going to the cooler at the rear is ok, but I wouldn't waste the $ on the extra hose and oil it would take. Not to mention I would worry about a possible drop in oil pressure or the extra work the oil pump would have to do to push the oil all the way to the front and then back. Just my 2 cents.

You could run long steal pipes with short hoses where flex is needed... There are some bikes that use the frame for an oil cooler-sump....

I have been out of the loop for a will,

But the guy's who raced outlaws with vw's

ran dry sumps with external oil pumps

and could mount the oil cooler anywhere.

Cool the oil all you want, but it will not affect the head temps unfortunatly.

Not worth the time/effort IMHO because there is no gain. Keep your head temps in line, and run reasonable rpms (extended periods of time) and spring pressures and the stock cooler is all you'll need.

From the testing i've done (going back to 1999 with this subject), oil temp is primarily due to shedding heat from the cam and lifters. There is heat put into it from other places, but this is the big one. Sustained high rpms (light or heavy load, no difference), and/or heavier springs raises oil temps the most. Example: my Berg dipstick on my bus will flicker (225-227 degrees) while going down a canyon at 65mph/4000rpm. But going up that same canyon, the rpms are lower and I never see my oil light flicker at all. Head temps going down the canyon are under 300, but going up the head temps are over 350, borderline 400 on some pulls.

Head temps are primarily from engine load.

I've gone the circles, going as far as removing ALL oil cooling from my daily driver bus to see what effect it had on head temps. It has none. As mentioned above, I was able to keep my oil temps below 225 while driving around the belt-route on a 95 degree day as long as I kept the bus under 54mph. Floored uphill, or 'cruising' back downhill, 54-55 was my limit to keep oil temps in line. Head temps run the same as they always do wether you let the oil cook, or you run too much oil cooling and the oil temp never comes up. Driving a VW here in Utah in the winter with a CHT gauge will show you that even with 100-120 degree oil temps, your head temps are still about where they are in the summer time. Cold oil just doesn't cool the heads.

Head temp is your critical engine temp. Keep that in line, and your oil temp should not be an issue.

Again, an oil cooler up front would not be worth the time unless you have a car that is running hard higher up in the rpm's for extended periods of time. Head temps, head temps, head temps.

This is great info. I am glad people like you do tests like these,to help all of us to make decisions on what to do on our cars.

Thanks
Rich

Great reply, Allred. Good info.
I agree Erik Thanks for a good thought out response.

Thats what is a textbook desirable post, whether you agree with the information or not (if you don't I would love to hear why?) that was informative and well written!
