Thinking of using a Ram air box setup on my 68 Charger with the stock flat hood. http://www.ramairbox.com/These air cleaner assemblies are sealed and use 4inch hose. My question centers on the inlet location. I'm thinking of running the inlets into the inner fender where air would be drawn in around the front wheels. Obviously there is no ram effect but I'm wondering if it would be worth the effort vs the current setup which is a standard 14x3 drop base assembly. Opinions ? Comments ? Ron

Very clean and neat. I like the whole car! Any performance gains that you noticed after intall? Thanks. I did it years ago when the original 383 was still in the car. If I remember correctly, I added it and changed carburetors at the same time, so it got faster but I can’t peg how much was this system vs the carb. Probably not much to be honest, but it certainly couldn’t have hurt it. It may be worth more to the current combo, since it is obviously drawing more air than the 383 did. Regarding the ramairbox purchase, the product is very nicely finished and still looks great years later. Don’t hesitate to buy from them.

Thanks for the pics and feedback guys !
StealthWedge : that looks great....nice job on the install. Unfortunately in my case I don't have room to go through the core support. My aftermarket radiator has side tanks and is quite wide.
Shadow/Mark : I guess the cowl could work with a cowl scoop ?
I'm trying to keep the stock flat hood and don't like the look of any scoops on a 68-70 Charger hood.
My thinking was drawing ambiant air from the wheelwell area has to be much better than sucking 250* underhood air. My question really centered on how much better would it run and is it worth the expense ?
Ron as far as 1/4 times I have no data, but after I sealed my air cleaner to my cowl hood the car ran much better on the street, the AFR was much more stable though the range of driving, the butt dyno says it had more power.

Spectra makes a kit also I got mine from Summit. I put the set up in my D150 and also put one hole in the radiator support and connected one to the factory ducting which pulls air from under the turn signal. I put a piece of screen in front of the support inlet to keep out bugs, etc.

Thanks Charlie.....that's what I figured. Stands to reason that a sealed carb to fresh air would show some improvement. Ron

Ron, a friend of mine has a super nice (& fast) 65 Coronet 500 with the 17"x 5"setup on his RB 512 stroker with 2x4's. Ducted to the inner headlight buckets with mesh covering the openings. Looks really trick & flows good. I know you can't do that with your Charger's concealed head lights, but Spectra makes a firewall ducted unit that draws air from the vents at the base of the windshield. Similar to what Petty did on his 64 NASCAR Belvedere. I'm considering that with my 64 Belvedere. BTW, glad to see you still have your 68 Charger & would be great to get together with Holly's Charger again. Buzz Hi Buzz, Thanks for the info ! That cold air assembly looks effective but wouldn't work on a Charger. The wiper motor is right where that firewall ducting would have to be spliced in. It is still a street car and I need wipers Does Holly still have the '69....allways loved that car Hope to make it back out to Vegas one of these years....allways a blast ! Ron

Ron you're in a bit of a quandary. Your machine is too nice to be cutting holes for air scoops in the inner fenders ,core support ,hell any place. Hey Mark, Yep....it's too nice to cut up. I might have to rethink the aftermarket hood deal. A 'Glass hood sealed to the carb would be the least intrusive option ( No Hacking)and provide some cool air with the ram effect. The added bonus would be a 50lb weight reduction on the nose. Just have to come up with something I like from an aesthetic standpoint. Ron

Ron Ron, I bought a one piece fiberglass hood with a 6 Pack scoop for the 69 R/T SE I had & gave it to Holly for his 69. Its stuffed away in his shed & he'll never use it with his Hemi, so if you're interested, I'll ask him if he wants to part with it. Landy used the earlier Hemi scoop on his Charger, but the 6 pack may work better since it sits higher. Here's one on a 68 from google images.

The 2nd gen Charger is a difficult one for a hood scoop, the stock hood looks the best, for me the cowl hood looks better on a Charger than other scoops.
