I am looking for a hood and bumper that

1. maximises the airflow to intercooler/radiator/coolers
2. has the best ability to dissipate heat

Thanks

 

The VIS carbon fiber hood for the 350Z and G35 is a very effective one for expressing heat. Note the addition of the scoop on the nose at the high pressure area, to help create a flow that sucks air out of the six "gills". The exhaust slits are angled towards the A pillars, rather than straight back onto the windscreen, which I also think is an advantage over many other designs. Mine is painted OEM white in this picture below.

 

For the bumper you will have to look around as there are many choices. Aesthetics as well as functionality are a concern. You may want to look into the aero characteristics at this time, if you are buying a new bumper, and something with some downforce is probably a good idea, as long as you look into some rear underbody diffuser to pull it down in the rear.....or....a WING!

Obviously, if you have a track car with FI you will have four primary competitors for air flow. The radiator, the intercooler, the oil cooler, and the power steering cooler. However, you should also consider two intake ports dedicated to ducting air to the calipers on each of your front brakes. (It gets real crowded up there!)
Good luck.

 

the biggest thing you want to do is make sure the air can escape. You can let in as much as you want, but if it doesn't have a smooth, quick escape route, you're just going to pile up hot air in there.

it's a bit more complicated than just a vented hood

 

Cwest or Ings hoods are very good venting.. also the veilside with the three vents.

front bumper i'd suggest the doluck, top secret, vertex.. all have wide three openings perfect for placement of oil coolers and intercoolers.

 

Try going with some better air disspension fenders to let the hot air out.

 

Hahaha. I thought about this idea, but then when you really look at the car you will see there is no coalition between the front bumper/ hood air inlets and the fenders. They are separated and blocked off by the inner fenders.

 

+1....someone needs to look in his engine bay more lol.

the key would be to get the air our the back of the engine bay faster, via rear hood spacers or a better airflow directive out the back of the engine bay.

 

Thanks for the input guys. I'll look into all the suggestions. Who sells hood rear spacers?

 

If that's the case, then Do-Luck Lift-up hood FTW!




However, No-Luck-USA FTL!!!

 

I have to agree, the No-Luck hood seems like an excellent design promote airflow through the engine compartment. But then again, WTF do I know?

BTW, yesterday we were sitting in Sonic Drive in, engine off, watching the heat waves coming from the vents on the Seibon VT hood. At least at rest, it really lets the heat out.

 

If price isn't an issue, I'd say Do-Luck. Otherwise Seibon VT FTW !

 

Just a few washers will do the trick, there is no custom part for the job necessary.

 

+1.. i can see the vapors coming out. it Appears to be releasing a lot of heat. also i know thats its pushing a good bit of air when moving as well because i spilled a little bit of oil on a hot pipe when changing a line. after heating up it was releasing a little bit of smoke. i could see the smoke coming up out of the hood. anywho.. just my .02

 

or... goto your reputable body shop, have them cut three holes, two rectangles in the front, one long and thin over the plenum, and have them bend the leading edge of each of the hole upwards at a slight angle, then you'd have your own vented hood. probably lighter than 80% of all the 'carbon' hoods out there and you'd only be down like $300 for labor and some touch up paint.

 

For the hood, I've decided to either cut the stock one (like Chebosto suggested) or buy one similar to Eagle 1's hood.

Now I'm still deciding on the front bumper. I figured since I'm changing it anyway, I should look for one that has some downforce. Besides Kognition, are there any others?
