Prob cheaper, lighter, and smaller cuts

 

Me again with another link for hood louvers. Great reading on the first as well as this one. This one also comes with the caps to close the louvers in the winter time. Senior Member, will you post if you think the idea is worth it (I'm a newbie here) so other members will see a cost effective solution to keeping those gaskets/engine/wires under the engine hood cool. Here's the link:

consider getting your ex manifolds coated with jethot or similiar (or heat wrapped)? cuts temps down rather well, seeing as they are the biggest source for heat

 

Anything come of the hood vent project? I was just thinking... if heat is not radiating off of the exhaust manifolds, it must be going out of the rest of exhaust... would this effect Cats or O2 sensors with added heat there?

 

it actually increases the exhuast efficiency by keeping more heat in the gas, alters the backpressure to measurable results in most cases in terms of maybe 1-5% in measured wheel power. as far as the o2's and cats, bonus there too... hotter exhuast means lower emissions... it would also warm up the system and change the loop mode faster, which is also better since the cats/o2s would warm up considerably faster being as starting cold with less initial loss from the cold manifold pipes sucking energy from what could be heating up the cat material and o2s.... once heated up to a degree the pipes even out thermally anyway. atleast the underhood temp would constantly be recieving less thermal input though! but higher temps also decreases carbonization, which is what coats the o2's and cat honeycombs that reduces thier sensitivity and effeciency. would the results be significant? probably not... but it certainly wouldnt HARM either system. plus, its CHEAP and easy! of course if you go with chemical wrap (ie. ceramic coatings etc) youll have to remove the headers, ship them, pay for the coating, then reinstall... definatly not cheap anymore haha but all the better. ive seen some people wrap coated headers too anyway lol, sleeves are under $20ish last time i was browsin the shelves!

I'd say it's ok for looks if you like that. But if you want to improve something, just make sure it pulls air out of the engine bay and not in, otherwise you could be reducing air flow through the radiator.

 

Humvees had radiators tilted at an angle thats why the original had the hood vent. the H2 just has a fake one as a styling que to the original. Not a bad idea to make it functional but I wouldn't like the fact that Hummer owners would be talking all kinds of smack, Good luck and post some pics.

 

A friend bout a jeep with this AEV hood. Anyone done anything like this for a disco?


The black sections are fine mesh screen over cutouts. The passenger side lines up with the air intake.

Would love to vent the heat off that Buick designed furnace ;-)
