Staggered hood?

Rx-7fetish · 02-11-2010, 11:40 AM

Not sure what people call this exactly but i have heard that it helps with under hood temps especially at idle. Any truth to this? Any other Rx's done this? Did hood long enough to take photo, its back to normal right now. And it looks higher than it is, i couldnt fit my pointer finger in the gap.

My buddy with an S13 did it and said it helped out alot.

It could help but for reasons contrary to what people believe. most people think it vents heat out, which it will do when the car is stationary. Under speed that angle is a high pressure zone and will for air INTO the engine bay, not let hot air out.

Then there's the cosmetics of it, not to mention the hood is designed to stay where it is if you rear end someone, I don't know how it will react lifted like that, it might stab you in the eye.

Ouch lol, yeah i know the saftey hazards, but my latch is kinda jacked so im gonna go cheap and get some hood pins, i figure this will help reduce the chance of this happening, (not prevent).

And i understand the fact that it will force air in. Im just worried about idle. I was just curious if anyone else here has done this, once i get it back on the road ill post my temp findings with it staggered compared to normal.

FYI- of you don't get some high quality hood pins, you would be making the car MORE unsafe.

Just don't do it.

I was just asking lol, its back to normal right now. Just wondering if anyone had done it before with a second gen, ive never seen it done to one. Didnt know if there was enough of a benefit at idle to do this, i go to the mall a lot and theres always a good amount of stop and go traffic.

Yes, it helps with cooling.
At low speeds or sitting in traffic, the air is blown over the engine then UNDER it.
With the back end of the hood propped up like that, the air has a little better time exiting out the top.

At speed, like TTT said, you get a positive pressure area built up at the bottom of the windshield.

Contrary to what others have said, there is no danger of getting decapitated.
If anyone has seen FC's in a bad front end collision, the hood is designed to fold.
The rear hinges are designed to keep the hood (rear) corners down and not shear.
There are no hooks that keep the rear of the hood down - some other cars have this hook assist.
The hinges have the sole responsibility to keep the hood from taking your head off.
I do NOT recommend replacing the stock hood hinges - now THAT'S a BAD idea.

Now the bad part...
Thieves can hook your hood release cable and pop your hood open without getting inside the car.
The stock route of the hood release cable is right on top of the driver's side fender.
It's very easy to grab the hood release cable and pull real hard - viola, hood opens.
Honda thieves do this all the time down here.

Is there a real need for you to do this? It seems unnecessary, and it obviously looks less than savory.

Kane · 02-11-2010, 05:56 PM

I didn't lift mine but I took the weather strip out, and my idle coolant temps are 2-5 degrees cooler....

Meh - for free it was better than nothing.

josh18_2k · 02-11-2010, 06:30 PM

its the jdm-tyte thing to do..
and yah it does help keep the engine bay cooler, altho how much totally depends on other stuff.
man up and get a drop vent! (win win)

Get a what?

Max777 · 02-11-2010, 09:14 PM

well, unless you have a crazy looking car already, then cosmetically it looks terrible. Some slammed widebody FC with huge flares n' shit could pull it off, but otherwise, it just looks too shitty to do this for the performance benefits.

classicauto · 02-12-2010, 09:00 AM

FWIW, aerodyne used to make hinges or spacers for that purpose back in the day (~2000) but I don't think they exist anymore.

IMO, there's better (looking and functioning) ways of cooling the beast.

gkarmadi · 02-12-2010, 06:16 PM

How much of a lift is that (inch)?? And where did u get the spacer??

Way way less i can barely get my little finger in there. No spacer I just loosened the bolts, tilted the hinge a little and tightened them down again. The hinges are made to have a little play so you can align the hood with the fenders.
