One option many of us have found helps remove heat from the engine bay is to remove the rubber at the base of the windscreen.

It is designed to be able to come off and then reattach really easily and creates a nice gap for airflow without making the bonnet bounce or shake any more than it usually does. It works well and costs nothing. I remove it at the start of a track day and put it back on for the drive home afterwards - takes 20s.

Here's a pic where I've removed part of it so you can see what I mean

Not sure if you are actually data logging, but removing that rubber makes the problem worse, it may cool down faster when you are going slow/in the pits but on track you will effectively make your cooling system worse!

Essentially this is the same as a few washers under hood hinges addressed previously....

Sure, if you want to make the heat problem worse. There's a big high pressure bubble at the base of the windshield and as soon as you give that air somewhere to go like the engine bay you increase the pressure. That increase in pressure evens out the pressure differential across the radiator and there goes your cooling air flow.

this has been debated before in the "Combating the heat" thread http://www.ft86club.com/forums/showthread.php?t=53580

I don't think it was ever solved, but I don't think it would be too much trouble to remove the seal, and tape some short lengths of yarn to the underside of the hood near the new gap and see if they get blown out at speed and tape some to the base of the window to see if they get sucked in.

As for the OP's original question, it was also addressed in that thread, page 31: http://www.ft86club.com/forums/showp...&postcount=427

What about @Reaper and cutting the windshield cowl?
