Getting the Cold Air

I have the Rb intake with high flow filter.. it sucks hot air into the intake.. obv.... anyways i was wondering if i put the stock blue intake on would it be able to suck enough air in though the small tube that runs up to the front for cold air.. if the engine is ported.. last thing i want it a restrictive intake, but i want cold air.. any ideas and will the stock setup be able to suck enough air? thanks..

I dont think the stock blue filter housing will fit on the Holley carb. Different diameter openings. Also, one of the "common" things to do is cut the walls out of the stock blue box to get more air, so I would think that people wouldnt do this if it didnt restrict air if you catch my drift...

Looks good mark . I knew that you had the lid vent, and I had seen pics of the snorkle, but I never put 2 and 2 together until just now, lol

yeah.. but if the stock thing doesnt flow that well then it looks like something aftermarket is needed... any ideas there.. i dunno i might just have to go aftermarket K&N round filter thingy i would love for there not to get the hot air sucked into it but i think im outta options..

Check it out man,, there are a zillion options. And yes, the setup i use flows as much as needed. really.. anyway,, i think what you need to do is check out the 2ed gen section 13b stuff. but for any car, the way to vent cold air in,,is through ducts, or vent the hood. plain and simple.

Manntis will have one available soon (cross fingers...) but whether it'll fit the RB frisbee hat is kind of up in the air...


his site's down at the moment, check www.rotorhead.ca periodically.

Carbs can also get too much cold air..depending on your climate..icing can occur or the carb cannot compensate for the increased oxygen charge and the mixture may be off.

oh even if i can run the vent.. i need the blue air box... first it doesn't flow enough air.. and it wont fit my holly properly... the performance handbook suggests the K&N round style filter element for racing but all i can see is lots of underhood hot air being sucked in especially when you are racing and high heats are involved..

I heard that the underhood temps aren't as bas as most think they are, these ain't no 3rd gens. Also if you're that concerned about underhood heat while "racing" you should think about venting the hood. Or fabbing a heatshield to protect the intake, if you do make ghetto cold air, you really can't use it between november and march.

Yeah, it's fine now but when I wrote that last night I couldn't bring it up. Maybe it was Bill Gates using the Dark Side of the Force on me again.

Everybody: Interesting points on the "too-cold" side of things. Manntis & I are designing the FB CAI to be an easily removeable mod, so if the weather temps drop too far you can simply switch back to the stock setup.

Do you make the vents?
How much more air do you get in through the vent? any idea? *I can't remember is that part of the car is a high pressure area*

Yes i make the vent,, I can make any vent, any size, any shape, and vents can go anywhere. pretty cool,,huh (get-it) Lol. Made out of metal too. I don't think the light lids are in a high presure area, that would be right at the bottom of the windshield, but none the less the way i setup the vent and the snorkel (inner cooler piping) at the end of the piping i fab'ed a scoop(sort-of) that mounts to the radiator bulkhead, it's rigid..if you look up in the vent you can see about half way up to the air cleaner canister. it's a straight shot. the snorkel and scoop are all air tight, no leaks. as far as how much air (cfm) the setup adds,, i couldn't tell you. because i can't measure it. does that help ??

yeah it helps. I got a GSL-SE with a cone filter on the AFM and was wondering if I should fab a cold air box w/air pick up through the rad mount or maybe do a headlight vent (like yours).
Thanks for the info

If you want to keep your car looking smart,( no outside mods.) then i would run some piping (even pvc) from the intake area in front of the radiator, then run it through where the over flow bottle is, it would look like an S.. i'll draw you a picture. back in a flash....

you have to remember, when ducting to a headlight scoop, that you sometimes drive at night.. what happens when your headlights are up. the vent no longer gets any air. are you then sufficating your intake? or do you have it so that it disconnects at that point?

(just a thought)

I have the Mariah NACA ducted front headlight lid (right side) and have reworked the standard SE duct (in front of radiator to A/F meter via radiator mount) to pull the air straight from the NACA inlet duct to the air-cleaner assembly. This required cutting back some of the rubber 'waffle' ducting that carried the stock mounts, but also allows you see the air filter assembly through the NACA duct when looking inside the headlight lid. This is a short duct, so I'm sure it develops some additional PSI, tho no way to measure the pressure at varying speeds.

For the rain consideration, I *wanted* the lid(s) to be up when it was raining to prevent the rain from being forced up the duct and directly on top of the air cleaner element (remember this is an SE with a flat filter element). When the lids are raised, they prevent RAM air from going up the NACA duct, but don't block off the duct, completely, since the intake ducting is then exposed at the joint between the hood and the headlight lid where it has depressed at the rear. This prevents rain from being forced into the intake, and also provides a cold air (tho not RAM air) source for the intake to draw.

The end result is a system that works well in both wet and dry conditions, provides RAM air at vehicle speeds, and also looks cool with the NACA design right at the front of the car. I'd post pics, but don't have a means to host. HTH,
