after a short brainstorm session with Roger Sheridan, brad and jason i've been busy bouncing around ideas about a good oil-cooling system and getting some air to my front brakes.
here's what i came up with so far: Oil-Cooling: my first idea was to just put a oil cooler in the front. i have a GT (916) front spoiler that already has the cutout for the cooler. but then, while looking at rogers car, i got a better idea. what if i put a oil cooler in the spot where the stock fresh air fan resides? this is a high pressure area (roger uses it as air intake for his tranny-cooler). i can then use tubes to run the air from the oil-cooler either inside the car (meaning i can have heat AND nice headers) or route it to the outside. the fans you see in the picture could be just 911 ventilation fans. using fans would also help cooling the car when i sit in traffic, which a normal front oilcooler does not do very well. any commentz?

A friend out here, runs that oil cooler set up on a 4cylinder race car. He doesn't bother with the heat though.
there is a significant difference in cooling capability when it comes to the duct work and air exit... I ran a restrictive exit on one of my coolers once. When I changed to an extremely not restrictive exit (hood of the car) I had a huge drop in oil temp even using the same cooler. So my thoughts on the cowl are: how big of a motor, how high of compression, how much oil temp drop do you want to get?.... also its kinda high up in the chassis to be adding weight if that matters (track car?) I also have seen people feed their brakes from inside of the trunk area. Reportedly, worked well.... no personal experience with it. I can say that I have noticed ducting for brake air to be much less bothered by restriction (ie right angles) than ducting or exitting cooler work. (hope that makes since?) brant |
