Ideas on functioning vents for hood or front bumper

[grdeclipse]

Hey guys,

I have been looking and looking trying to find a better flowing front bumper for my 1GB talon. The only bumpers that I can find are ridiculously ricey and look like crap. If you have modified you stock bumper or know where to get one that looks as much as stock as possible please show me what you did or where you got it. Also I'm trying to figure out some good functioning hood vent ideas too.

Thanks

This is a hot topic in the road racing forum, as we run into cooling issues pretty often at the track. What's been found is that the stock bumper, unmodified, is actually not what needs to be replaced in most cases. Yes, you can modify it like some have done in the above photos, but that's just a band aid. The true problem is the lack of ducting that needs to route air through the FMIC and force it into the radiator, then venting that air through the hood so that the hot air isn't trapped behind the radiator once it passes through. It needs to escape from under the hood.

You need to make sure that the passage between the FMIC and radiator is sealed all the way around and that air cannot escape, it must have nowhere else to go but through the radiator. Then, you give air a way to escape through the hood once it's gone through the radiator. The most effective and popular approach to this is the Carbotrix hood vents sold by RRE (18x10 Carbon Fiber Hood Vent [18x10 Carbon Fiber Hood Vent] - $169.00 : Road Race Motorsports, Mitsubishi Suzuki Fiat Hyundia Performance Parts or 18x10 Fiberglass Hood Vent [18x10 Fiberglass Hood Vent] - $99.00 : Road Race Motorsports, Mitsubishi Suzuki Fiat Hyundia Performance Parts).

Doing both of these things, along with adding a cooling additive like Redline Water Wetter and high flowing fans and you should be good. No need to cut holes in your bumper cover or use some aftermarket alien-looking bumper design with a bigger inlet.

That is awesome advise makes total sense to seal that passage between the fmic and radiator. Do you have any pics of what you did to yours and what kind of materials you used? I really hate to cut anything into my hood or bumper (just because I don't want to mess up and have it look like crap) but I keep telling my self that it really shouldn't be that hard. Anyways thank you for the advise and the link for that vent.

I was thinking of something like that for my front bumper too. Where did you get that duct from?

 

[agarc023]

They sell em on ebay

The duct is for a 350z. That should help the search. I always wanted to box/duct the rad and do a hood vent, but never got around to it. The vents I ended up using were good for ~3* drop in temp while moving.

the duct is actually STM's duct for my forward facing manifold

Amazon.com: Left Carbon Fiber Bumper Air Duct Intake for 2003 to 2006 Nissan 350Z: Automotive

I do not doubt that it serves that purpose, but it is nearly identical to the 350z ducting that's been around for years.

i'm just letting him know where i got it from

Those were all good resources that has my brain currently thinking of what I might do. Now all a want is a plan square vented hood scoop that would go about my right side headlight to site above the air filter so it can suck in cooler air rather then the engine heat.I do want some stupid big scoop but rather a vent style that stick up a little to catch the air probably around 12" wide to 18" long maybe samller. Anyone see something like this.

Thanks
