does anyone make a vented hood for the d1 similar to the rangies around '88? don't know how practical they are or what problems they'd create, but they look pretty cool for those times when i feel like a poseur (for anyone who remembers that thread).  | ||

There was a thread last year on how to do it. Have you searched the archives? | ||
| Kevin Howell (Kevinhowell) New Member Username: Kevinhowell Post Number: 38 Registered: 02-2003 |
yeah, i found the one where a guy was talking about doing that and adding a spare tire mount, for whatever reason. but he was just in the designing stage (carbon fiber or something) and most of the thread centered around how asinine it was or wasn't to have a spare tire sitting on top of your hood. some pretty funny pics on that one. | ||

Someone else added a vent from another vehicle. It was probably mid last year, but it may still be in the archives. Turned out pretty nice. | ||

How useful would a hood vent be, given the amount of airflow over a running engine both from the electric and viscus fan, and out the bottom of the engine compartment? I'm all for decreasing the temp in there, as I've been unable to touch the hood of my truck on some of my summer desert trips, so if a vent is the way to go, I'm very interested! | ||

I believe that one gut used a subaru impreza hood scoup, and it did look good, the other pic that i saw, well, a set of yugo,or fiat brava vents, one on ea side that are flush with sheet metal, they also looked ok, both said that it decreased under hood temps! if you do this, you MUST post pics.

There were pics of the one I was referring to. It was the impreza vents. I guess he just went for it...dremmelled out the holes in the hood and popped the vents in. Looked great! I was actually going to do it myself once I saw his. I thought i had the pictures saved, but I couldn't find them | ||

Archive search is a wonderful thing. This might be the one I was looking for, but I'm not sure. These are from a Renault something-or-other. The one I was thinking of gave step by step instructions. This one just said, Renault vents and gave some pics. If you wanted to do it, I guess it would be fairly self-explanitory.   | ||

That's a bloody good idea. Perhaps Ol' Drippy won't start it's temper tantrems in the heat this year. | ||

The toyo 4-runner has the impreza style hood scoop/vent now. here are some options: http://www.jcwhitney.com/catsubpic.jhtml?CATID=4033 http://www.jcwhitney.com/product.jhtml?CATID=55409&BQ=jcw2 Here is probably the cheapest way to do it...but you get what you pay for ;) http://www.rightcoastcrawler.com/billaVista/Vents/vents.htm | ||

Simple way to increase airflow from under hood area - Remove the rubber sealing strip at the trailing edge of the hood More complex grab a drill and make a few holes Very complex install vents as above my favorite, the rear vents from a Volvo 245 hopefull this link will work and you'll see a little black rectangle. http://www.linkline.com/personal/dbarton/Dave%27s245-2002.JPG | ||

A la the Homer Simpson "speed holes" with the pick axe? hmmmmmm Sounds simple enough... | ||

Why don't you simply raise up the hood where the hinges are? Looks good too. Might need a little "giggery pockery" but we used to do this many years ago (during my racing career). Alternately, ceramic coat your extractors/exhaust, this alone will reduce your engine bay heat by over 50%. BTW. Greg, how much cooling do you think the vents in the Renault picture will give; sweet F@#k all I bet! Any air will simply flow over the top of the vents. | ||
| Jason T. Barker (Speedminded) Member Username: Speedminded Post Number: 161 Registered: 10-2002 |
....the Renault vents are exactly that, VENTS! They are not intended as an intake, just dispersing the heat already under the hood. Cool air is brought through the grill and dispersed either under the vehicle or through the vents in the cowl under the windshield (and your heater in the winter). I have already removed all the foam rubber to allow more airflow through the cowling and taken off the heat shield/insulator from under the hood (basically using the aluminum hood as a heat sink) but I still think it needs more. I don't think the Disco needs to intake any more air but just let what is in there out. Insulating the headers would probably help alot. So far I have not found any vents that would not look ridiculous on the Disco's hood. I may just cut out some rectangles near the rear of the hood and install some flattened expanded aluminum. Roland I like your idea on the raised hood but would not want it like that all the time. I wonder if someone could devise a mechanical way to manually raise the rear of the hood up from inside or maybe even thermostically controlled? (similiar to the spoiler on Turbo Beetles and Porsches that raises when a certain speed is reached) Ok, maybe I went a little far there As you can see, this is the underside of the hood.  This picture is similiar to the inserts I want to make:  http://www.negative-camber.org/crispyrx7/extras.htm | ||

XJ guys do this sort of shit all the time because of their crapy cooling systems. I believe I have seen a place that will even take and cut vent holes into your hood they sort of cut and then flare the metal up hard to explain but it looks stock (well as stock as slits in a hood could look). Poke around a jeep (mostly XJ I think) site and you will probablly learn more about this than you care to know. I've never even thought of doing it simply because I have no real heat problems (I owe it all to my 'chicken wire special' grill -dripping in sarcasm ) | ||

A couple of guys have used the hood vents from Nissan Patrols down here, usually to feed diesel intercoolers. I just check Nissan USA, and you guys don't get the Patrol up there - it's along the same lines as a Landcruiser   | ||

Greg, no Patrols in the US, or else, mostly everyone would be swearing by them as a LOT of people do in the rest of the world (just sold my 2002 GU shorty for another Disco!). I will be installing a 2" body lift, which I am hoping will decrease overall heat in the whole drivetrain. Also, I've already poked a LOT of holes in the grill. With the addition of the M8274-50, which appearently blocks a shit load of cooling air, I may have to resort to other means of cooling... | ||
| Kevin Howell (Kevinhowell) Member Username: Kevinhowell Post Number: 43 Registered: 02-2003 |
now that's exactly what i'm looking for. one like that nissan patrol. that looks sweet. | ||
| Jason T. Barker (Speedminded) Member Username: Speedminded Post Number: 174 Registered: 10-2002 |
yeah, US gets all the crap. No Patrols. The 3rd generation Nissan Pathfinder is made from a Maxima chassis. No Mitsubishi Pajero's. What about diesel Land Rover's? You call that a Lancer? When someone says Lancer I think EVO, not some POS front wheel drive non-turbo Mirage looking thing with a bodykit and 150hp. I want to see Nissan Skylines and Ford Cosworths racing on US streets! What about Holden [HSV]....I think its about time someone stepped up in the ring to face BMW's market in the US even if they are just using a corvette engine. I'd like an Audi S6 sedan, not the wagon please! Both the Vauxhall VX220 and Lotus Exige would look good in American garages. Why not any Defender 110's other than the ONE year they were here? I could keep going and going on cars I wish we had in the US. Anyone here have access to this months Australian 4WD Monthly? I want to see the article on the Disco's. | ||
| Greg Tearne (Gooddoggomez) New Member Username: Gooddoggomez Post Number: 5 Registered: 02-2003 |
Jason I can try and scan them, save as jpg's or pdf's and email them to you. Its not a bad article. You can buy them online, as well as back issues. There was another good one about 6 months go as well. There has always been a trend in Australian mags to slag off Rovers, being the land of the Landcruiser. They seem to be changing their tune in the last couple of years. 4WD Monthly is definitely the pick of the litter though. You aren't missing out on much with the Pajero. The Patrol, however, is a great truck. They have a 3.0lt and a 4.2lt diesel models. If I weren't such a "rover-nerd" (as my Mrs puts it) I'd definitely have a look at one. As for the Holden HSV's, I believe they are selling the Monaro in the US as the Pontiac Firebird. But those kind of motors aren't my bag so I'm not sure. | ||

would the ram air type deal on the hood mess anything up. Engine wise would it damage anything. | ||
| Greg Tearne (Gooddoggomez) New Member Username: Gooddoggomez Post Number: 6 Registered: 02-2003 |
Blake My understanding is that they simply feed cool air through an intercooler, which cools the diesel fuel therefore making the engine run better/more efficiently. Not sure if there would be much of a practical reason to fit one to a petrol engine, besides air-cooling the engine bay. That, and having somewhere to put your mail. gtt | ||
| Blake Luse (Muddyrover) Senior Member Username: Muddyrover Post Number: 784 Registered: 02-2002 |
yeah i was wondering what added benefits besides "style" and a cooler engine bay and of course a new mail slot are their for the petrol engine. | ||
