if i can hook it to the part of the cowl vent the AC was hooked to on the inside of the car i may do it that way.
Are you sure you want to have a pipe directly from the carb to the car interior bypassing the firewall? Wouldn't a backfire blow fuel into the cabin? Maybe I'm not understanding what you intend to do.
never thought about that, u make a good point. my car used to have AC before i removed it all (it never worked anyway, just dead weight), i was thinking about sucking in cold air from the hole under the dash where the AC would pull in fresh air from the outside, of course it all wouldnt be open i would have to seal it to prevent air leeks , if it did back fire it would prolly all go out through the cowl vent unless im mistaken.
Why would you even think about putting it into the interior cabin? The way that racerx put his into the exterior cowl it draws fresh air from the "grate" on top, in front of the windshield wipers. Its just a matter of cutting a hole and sealing it up around your air filter... And as a bonus if your inner cowl is rusted out it makes it even easier to do it because you can do it while you have the upper panel off to patch up the rotted out cowls.
cuz i figured i could get cool air by hooking it to the interior part of the cowl vent on the inside being that there is a an open hole where the AC unit would take in fresh air from the outside(on the passenger side of the car), that way i would have to cut anything at all.
How about like this?? Everything is from Spectre except the carb hat. This is a 3 inch hose. The mount point as you can see is on the driver side front radiator support. All the Spectre parts can be found at O'reilly or Auto Zone.
Personally I don't think the interior drawing of air will do anything for you as there is very little pressure drop. What you want is either to ram the air in like the ole Thunderbolts, or use a pressure differential like what the NASCAR guys use. When I restored a "real deal" 68 Z28 with the road race package it vented to the cowl. You can buy these plastic cowl pieces or make you own out of sheetmetal or aluminum and modify a regular Ford aircleaner and make it work.................and they work very well. Drilling some 1" or 1.5" holes in the firewall is nothing, if you ever don't want this type of aircleaner you can weld some plugs in the holes and knowone will ever know. Here is a picture of my 68 Z28 setup.................and it works very well. The only issue with the big tubes running from the radiator core support to the air cleaner is that they are fine for short 1/4 mile trips, but for everyday normal driving because of the heat the motor/headers/radiator give off the air in the tubes is not as cold as you would expect. Oh, for some of you guys who do not have a Chevy background, Yes, it was a numbers matching, Protecto Plate, real deal Z28 with the Trans Am air induction and "factory headers" that came in the trunk from Chevy in mid 68. The car is now in Sweden. IMHO
hmmm......ok. i could do sumthin like this, looks a little small for a V8 tho i would love to go for this, and put lo-pro hella driving lamps hehind the grille if it would work. Hella lights below http://www.summitracing.com/parts/HLA-005750952/
I don't know about you guys but I think the carb does great job at cooling the air. Unlike Multi Point Fuel Injected engines
It's fine, and two will be more than plenty. Just because it's a V8 doesn't mean it'll need 10,000CFM. Look at the air horn on your Carb. It's only 5 1/8th"s and your throttle blades add up to less. But it's more than enough to feed a V8.
RacerX, Yes, right at the bottom of the windshield is a low pressure area, with an opening directly to the carb you actually draw the air into the carb, the faster you go...............the more air is drawn in. The other way is to "ram" or "push" the air in like a forward facing scoop of dual snorkles like the old Ford Thunderbolt had with a large tube on either side of the aircleaner. Maverick75, You would be very surprised at actually how warm the air is being drawn into the carb from the engine compartment rather than being pulled or pushed in from outside.
ok.....now how would i keep that hose from getting hot? ive seen those thermal jackets for cold air intakes at jegs.
Oh I know how hot it is and the huge benefit you get when the air drops even a few degrees. I was just mentioning something that no one has, The air being drawn in is cooled when it's mixed with the atomized fuel via the carb. VS a MPFI that does not have that benefit since the fuel is injected right into the intake port on the head. I think that's the main reason why you don't see many Cold Air intakes for carburetor engines. While as MPFI engines have a plethora of these on the market: And there's a lot more variables also, like car aerodynamics and velocity being affected by pipe diameter, etc. But on a street car it's just best to keep it simple and not get into all that.
I don't think those jackets even work all that well, the air will not even be in the hose long enough to warm up. And the air that is closest to the walls of the intake moves the slowest, it basically insulates the majority of the air in the hose from absorbing heat from the walls of the hose. Running smooth tubing would be way more efficient than the wrap on the flexible hose. The improved air flow from the smooth walls in the tubing out weighs any slight losses in power from absorbed heat.
