nuke I have a crazy idea..

run the sport in your test run with no hood at all.. ( or lift the back end with spacers on the holding arms )

We are all taking of getting fresch air IN the engine bay trough the rad
BUT
no body have thought that in order the fresh one to get in, the hot that already is there has... to go!!!!!! ( making it like an air pocket )

if there is a protective metal plate underneeth it also blocks the air to leave

Just an idea and taking advantage the test equipment you have..
