The trunk is vented thru the wheel wells. My mechanic says he thinks we do not get enough airlfow at idle. I am worried the pump is not working properly, although a lot of guys use these conversions with a regular water pump. We are investigating the system to see if there are any flow restrictions. I had thought of adding an electric pump as well. I thought it would be nice to be able to manually switch on the fan and the water pump to cool the engine even when it was not running. I am not sure if I go electric if having the regular pump as well will work, or if it would be a restriction in the system.

The race gas is only $5.80/gallon.
