Default Air intake with tilted radiator

Hey, I am considering tilting my radiator FWD. The biggest hurdle I see it relocating the air intake. I do not want to remove my headlights....

Does anyone have experience with these intakes? I think they look pretty sharp, but I struggle to find a place for them that is high pressure. Every where on the hood seems to be a low pressure area.

i also have trackspec vents...

I went with a radiator that was 4" shorter side to side but twice as thick. That way I had room to run the intake between the frame and the duct work for the radiator.

This is the first year for this setup, I don't drive the car (99FRC) on the street It's just for autox and hillclimbing but because one of the groups I autox with requires all cars to be street legal I have to keep the head lights. With this crappy year I only got to do 10 autox's and all of the hillsclimbs were canceled this year but the hillclimb group did run 2 track events at summit point. The way they were run you only got to do 1 to 3 laps at a time. I'm telling you this so you understand I don't know how cool the radiator will keep the car in a normal 20+ min event. It worked just fine at the autox's and trackcross events even on 90+ degrees days.

OP, contact @GSpeed they make bolt in kits for C5/C6. They would have a lot of info for you.

Keep in mind you may need something better than trackspec vents and convert the front of the car to a front breather vs bottom breather.

What's the purpose of the car? Just a street car?

That thing in the original post is a run of the mill NACA duct. Don't buy whatever snake oil that company is pushing.

? They don't claim it to be anything else. It's just a formed NACA duct that allows you to connect your own tubing to it.

OP is it safe to assume you're pushing the car hard for long periods of time and have already tried simpler "fixes" first? If not and you're having cooling problems, there are simpler things you can do to without having to reinvent the cooling system.

Yes, the car is basically just a street car. It all boils down to the fact that I want to do it and I dont have a better excuse than that. I was thinking a tilted radiator with a remote located electric WP and PS pump would be a nice winter protect. Looks like a slightly less wide radiator with more core thickness is a viable option. The NACA duct, if far enough forward to enter the high pressure areas, could feed the engine pretty well. However, with a narrow radiator, I can pull air from the factory locations.

I never went to their site, but the fact they felt the need to "brand" a NACA duct comes off as extremely douchey to me.

purpose of this thread was to see air intake options with a tilted radiator and headlights. Not to bash a duct. I dont much care about the duct.

My intent wasn't so much to bash the duct, rather to point out the fact that it came off really hokey to me so buyer beware of the overall theme of what that vendor was selling. NACA ducts are excellent pieces and I use them on my own race car. Clear ducts are nice because you can paint them from the back side which helps prevent dirt and rocks from chipping the paint off. If they're not lexan though, they won't hold up to rocks and bumper to bumper contact.

More on topic, unfortunately I don't have pics, but my friend had his intake duct plumbed through the frame rail on his setup with a forward leaned radiator. 3R did a really clean job on that, but I'm not sure if his filter and plumbing would have cleared a headlight as his were deleted. Something worth looking at if welding is on the table. Has anyone ever made a bridge over a leaned forward radiator before? That may be a good way to go too if it's designed with that in mind from the get go.

I have seen some photos of people cutting holes in the front frame rails for the air intake. I wasnt sure how kosher that was. Frame Strength up there prob isnt needed unless in an accident. I guess if you box the hole its not that big of a difference, but it made me stop and think before just punching a hole through. I also see people cut the front cross bar out of the frame and bolt/weld in a bar. I have the same opinion on that. I know enough to be worried, but not enough to say it is fine.

Install the new before cutting out the old and you should be good. I think in a frame bending wreck punching an intake tube shut would be the least of your worries. Could flip the intake backwards and draw from the wiper cowl, but I don't think I've seen that on anyone's car yet.
