Kittamaru Posted January 7, 2009 Share Posted January 7, 2009 As the topic says... would introducing cooler, outside air into the engine bay help engine performance at all by cooling the air entering the airbox? Just curious as I plan to do a snorkle at some point... and I know the cold air it takes in helps a bit. Link to comment Share on other sites More sharing options...
GrimGreg Posted January 7, 2009 Share Posted January 7, 2009 I know a few guys who have added vents to the hood to clear heat, but not for the purpose of cooling intake air. Link to comment Share on other sites More sharing options...
Kittamaru Posted January 7, 2009 Author Share Posted January 7, 2009 Is there any reason to or not to do so? Only thing I can think of is water getting into the bay... would cold water hitting the outside of the block cause a problem? Link to comment Share on other sites More sharing options...
GrimGreg Posted January 7, 2009 Share Posted January 7, 2009 Ever raised your hood after driving in the rain? It gets wet from the bottom already. Here you can see where he put the vent at the rear of the hood: Link to comment Share on other sites More sharing options...
shift220 Posted January 8, 2009 Share Posted January 8, 2009 One option is these bolt on or weld on hood louvers that this company makes... http://raceace.com/ They look pretty good but they seem expensive for what you get. I've been trying to find a local company that will stamp louvers directly into my hood Link to comment Share on other sites More sharing options...

I've been trying to find a local company that will stamp louvers directly into my hood You're right they do look way cool, but who in their right mind would spend that kind of spread on them. Maybe at most $50 if I was feeling more impulsive than normal! I don't see it being that hard to dubplicate this in some fashion for a fraction of the cost though.

bitemedoughboy.com Posted January 8, 2009 Share Posted January 8, 2009 if you want cheap louvers go to a jy and find an older car that has a metal grill in front of the windsheild (i used on from a datsun 610 car) trim them out leaving about 1/4 to 1/2 all the way around and weld them in your hood. i did that to my '54 willy's truck, made a hell of a difference.

Kittamaru Posted January 8, 2009 Author Share Posted January 8, 2009 I don't think I trust them to be quality parts... Why...? From their Q&A Q: What about water running through the louvers and onto my engine? A: No problem. Water doesn't hurt your engine. After all, many car enthusiasts wash their engines many times each year. As explained in the directions, you don't want water to get on a distributor – but most vehicles built in the past 15 years don't have a distributor. If you do, and if it's a V8, the louvers will be outboard of that, so no problem. Also consider the alternator – but the louvers are usually far enough behind that not to matter. Otherwise the instructions provided explain how to make a rain diverter. Buh? Link to comment Share on other sites More sharing options...

alexrex20 Posted January 8, 2009 Share Posted January 8, 2009 I would agree with that statement for the most part really? because your pathfinder has a distributor. Link to comment Share on other sites More sharing options...
88pathoffroad Posted January 10, 2009 Share Posted January 10, 2009 You can always just use some washers to space out the hood hinges and lift it up in the rear. I remember some people doing this in the past and it helped with cooling while on trail runs, etc. You have to make a few adjustments to the hood latch but otherwise it's really easy to do.

Fiew of my friends do that with their muscle cars(actual 60's and 70's ones) works great for them. I got plans personally of doeing some hood hacking. Mor efor a little visual but with the bonus of keepin it a little cooler between the fenders. Link to comment Share on other sites More sharing options...
Kingman Posted January 10, 2009 Share Posted January 10, 2009 You could put the hood ventl things from the Iroc Camaro hoods. I seen someone do it to a cherokee and he said it worked just fine. Link to comment Share on other sites More sharing options...
jj big shoe Posted January 11, 2009 Share Posted January 11, 2009 (edited) I've seen a few XJs with old Chrysler LeBaron louvers. Looks pretty good. Linky Edited January 11, 2009 by jj big shoe Link to comment Share on other sites More sharing options...
