Oil cooler scoop, does it work?

bklyn · 08-19-2010, 04:18 PM

Does anyone have or know if the engine oil cooler scoop really works? I think it looks good and if I could knock down a few degrees it might be worth it.

IMO, you probably won't see any benefit unless you are on the track or at highway speeds.

Lots of opinions here>oil cooler scoop? yes or no

Thanks for the site.

FWIW, I am constantly at freeway speeds and find that the scoop does shave off a few degrees. And it looks pretty cool too.

Where does the air come in without the scoop, under the forward edge of the cooler?

I have a SC engine in an early car with no aux cooler, but no racing or other hard duty.

My SC has a slot in the underside of the bumper that allows air in to the cooler. I assume all 911's with oil coolers have this slot?

Correct. I believe in 85 or 86 Porsche enlarged this opening to help in cooling.

bkyln--It isn't going to hurt anything to install the scoop. You may even see the temps come down more than expected.

I see a drop in temps on the highway. What really helped was putting a ducktail on the car! I actually have to take it off in winter because the engine never gets up to operating temperature when I leave it on in cold weather.

First time I read this. Thank you Kurt.

that's really interesting, I haven't heard that about the ducktail before. I wonder why the tail would have a cooling effect.

As far as the stock opening in the bumper for cooling, it really isn't much.

Mine is fine!

I don't know but the tail might push more air down the engine grill, I'm only guessing.

On my 87 they did enlarge a slit opening just above the valence but for the price I just my give this one a shot. Cant hurt.

I have one on mine, and yes it won't hurt.

I use the scoop and a carerra cooler from Elephant racing on my race car and I have no issues with the engine getting hot.

kidrock · 08-23-2010, 09:02 AM

I've read dozens and dozens of threads on the myriad attempts to get these cars to run cooler, whether the heat is caused by hot summer temperatures or tracking...and I have yet to read a thread on "The Silver Bullet". If one existed, 90% of the Pelicans would be using it.

The closest thing I've heard of as far as the real deal would be the center-mounted auxiliary racing unit (Mocal?). And maybe the 2nd auxiliary unit being mounted in the driver's side fender. I've heard some good things about the Elephant unit as well.

So IMHO, anything goes. If it works even a little bit, go for it.

P.S.---the jury is still out on the "Cooler Collar".

I run a early turbo tail in the summer because it keeps the temperature down and helps the air condition blow out "not so hot", air. Cooler air would be an overstatement out of my A/C.

The oil cooler scoop, as it comes shipped, does not work.

If you look at it, there are no internal baffles or air guides. The air flow immediately dies off and you lose pressure going to the cooler fins. It is an excercise in wishful thinking. To flow, you need high pressure on the front side of the cooler in order to force air to flow at high volume through the cooler fins.

The small volume of air that would go through the scoop, assuming a good design, is not enough to flow the cooler at high pressure. In really hot, thin air, you'd have to be going 90+ mph to get a lot of airflow from a small scoop, assuming it was designed well and ducted right on to the cooler. The reason that brake cooling scoops are ducted right onto the rotor is to direct this high pressure air and force it through the rotors.

I bought one and realized all of this, so I modified mine with a Diet Coke can and some tin snips and epoxy. It might flow more now, but I rely on the electric fan to really force air through the cooler. The cooler scoop is still there, but at best it feeds the fan, which does the real work of feeding the oil cooler.
