Cooling system for Penny..

[harshman]

If my memory serves me correctly, shrouds are required for mechanical fans only and can be considered restrictive otherwise. This is not my opinion but that of many a racer. Fans are only for low speed air flow and are not required above 35 mph. Yes a idle fan is restrictive – just put your hand out the window doing 50 mph and you'll get an idea, however I think we are approaching more cooling theory than general purpose as which I think penny will most likely see (track and street). Ideally a radiator will work most effectively when unrestricted airflow touches all the fins.


All this to say that you will be fine.
