Improving 2.0 /4 stock cooling system Options

[Mueller]

Since my /4 will be under the influence of positive manifold pressure, i think keeping the motor cool will be a major concern.

Since I am on a tight budget (who is not these days) I cannot go to extremes with products like the 911 fan conversion or the dual electric fan setup. My dream setup is a horizontal fan, but for now I need to keep the stock 2.0 FI plenum and manifolds, besides, the bevel gears are loud and rob horsepower and the oil fill housing is in the way for a clean setup.


Has anyone changed the fan? or modified the stock fan for better flow? i know that some have removed a few fins but I thought that was not good for a motor that might have to idle for long periods of time like in traffic.

Can anything be done to the fan housing assembly to improve the airflow?
(baffles, diffusers, vortex generators???)

I know it would only cool the back of the motor, but I had thought about machining the back of the flywheel to create "fins" that could assist in suppling air to the motor...crazy? yea (IMG:style_emoticons/default/smile.gif)

We did the same thing when we were trying to figure what to do about cooling my race car off. We used some stips of cloth and tape and found the air flow was very turbulent over the engine lid since the area just behind the windshield is in a vacuum created from the engine sucking in air and the poor aeodynamics of the roof line. That is why we went with the curved air deflector but on a street car it would look really "ricer"! I would face the louver openings to the rear as most hot rods I have seen have theirs that way. Good luck
