Any race guys ever run a 3 or 4 inch hose mounted off the front air dam or attached near the outside mirror thru the rear fire wall and directed onto the fan? Does it add any cooling effect? Any pics of setups?

Probably the most efficient method, with all of the %'s aside is to use fans such as in pict #2 above which is the #22 Wayne Baker car and then use an alternator, specially wound, so it will freewheel until over 4K RPM and then put out the 12 volts needed. There is no fan on the engine and the air ducts blow directly on the cylinders and heads. This setup is terrible for auto-x but GREAT for road racing. When Ron Mistak would bring #22 to the stadium in San Diego, his crew would always have a jumper batt on a cart handy since it would nearly always need jump starts.

When Ron Mistak would bring #22 to the stadium in San Diego, his crew would always have a jumper batt on a cart handy since it would nearly always need jump starts. There is a third fan on the 22 car located to the rear of the motor and dumping air to the two rear cylinders. Mugs914 works on the car and said there is never a heating problem on the track. Car also has a big oil cooler mounted in the location of the fresh air vent opening in front of the windsheild. Hell of a car. 2.0L with BMW mechanical fuel injection. |
