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)

I doubt if you can do much to the fan.

Use a cooler for sure.

The single biggest improvments are going to come from getting more cool air into the engine bay.
Use a GT deck lid. If the turbo is going into the bay try to isollate it from the cooling air. If you like to cut and hack maybe some NACA ducts in the rockers (a'la chuckster, I think) and duct them into the engine bay.
Hey you have the rice wheels how about a big f'in hood scoop! (IMG:style_emoticons/default/wink.gif)

Has anyone tried a GT lid with two rain trays? would this help/work?
Maybe I should start a new thread for this question.
