removing hood weather strip
 
Hey, tried a search but nothing returned, or I'm searching for the wrong thing.

Anyway, has anyone here removed the strip of rubber near the windshield cowl? Would it provide a similar effect as venting the hood? We all know that there's a low pressure area there, by allowing it access to the engine bay, would it help pull out all that hot air near the back of the bay?

I've had mine gone since I bought the car and haven't noticed anything bad, other than occasionally i get a blast of hot air with the top down... perhaps that's proof that it works. Maybe someone who still has it in place can use a thermometer to see if removing it actually does anything.

hm... meant to say removing the hood weather strip, but there's no way to change that now.

Double click on the thread title from the main screen of the section. AKA: click on general miata chat, then double click on this thread. The author should be able to retitle the thread for up to a month I believe. I could be wrong.

Anyways, try search for "hood spacers" instead. Removing the weather strip has a similar effect, and you should get some answers with those terms.

You have it backwards. High pressure area near the base of the windshield.

Essentially, you're going to pressurize the area under the hood, allowing less air in through the radiator. Not a good idea.

I double click it and it gives me a split second to change it before taking me to the thread... not enough time. Maybe it's a firefox issue.

But yeah... if it's a high pressure area, where does the air that goes into the engine bay exit from? if it gets drawn down then back out the bottom, it can still provide some cooling near the back of the engine. It would be interesting to see if we can change the pressure in that area by changing the shape of the trailing edge of the hood.

Assuming you have a liquid-cooled engine, there is no reason at all to introduce air into the engine bay from the base of the windshield. You want to maximize pressure differential across the radiator (ie high in front, low behind). Allowing air in from the back negates this and will reduce the airflow through the radiator.

See? I do read and learn.

Alright. I'll probably go with the mini scoop if nothing else.
