GTM Motorsports Oil Cooler

Works for everybody. Adding high flow cats leaned mine some also.

Again, something I've not played with as I've gotten away from ported or Billet MAF's after finding out most of the local tuners preferred the stock MAF's. Certainly something to digest and think about.

Speaking of something to think about and digesting.... Yesterday again checked intake temps on pretty much a standard stop and go route (to my health club to workout) taking the back way to avoid as much traffic as possible. About four or five lights, depends upon luck on how you hit them, however with a few stop signs in the interim. Key is standard route.

The intake temps basically ran 12 degrees over ambient going down to about 10 during open throttle in 72 degree ambient and some light rain. This was 4 degrees hotter than the day before. Same route, slightly different conditions.????

OK....rainy days, Sundays, and high temps gets me down.

Small air diverter pop-riveted to underneath bumper. (Way to small, just trying be conservative)

Sections removed from bumper picture by dennylmclain - Photobucket

Removed bumper and removed two 2.5" thick sections directly below the filters.

3/4" of opening removed picture by dennylmclain - Photobucket

Removed 3/4" of the rear area of the openings creating a gap. (top three middle sections of the front facade)

A good two inch thick and six inch wide straight shot to the filters so they don't have to pull air from behind and the fans pull air to them.

Looks untouched. What happens in Vegas, stays in Vegas and now you know how the magic trick is done.

Same route, same conditions as yesterday: The car drove 7 degrees over ambient going down to 4-5 degrees during open throttle. 20 minute drive to health club, 187 water temps and let the car idle for 3-4 minutes. The most it got up to was 93 degree intake temp or 21 over ambient.

On the way home after a 45-50 minute workout: 93 degree initial intake temp, went down to 82 driving temp within a mile and 80 WOT. Went to 8 and 6 over by the time I made it home with hot engine.

Simpler for me than routing tubing and seems to help some. Next move is a larger air diverter and isolating the rear of the filters some from the radiator.
