how bout some pics of custom cold air setups
here's mine to start it off, the ends of the hoses are out of view....they run to a 4" mount bolted to lower corners of the rad support and draws air only from outside the engine compartment.

I did mine several years ago.

68 short step,
hope you never have to pull that radiator! Nice metal work by the way. I like the clean look. ![]() ![]()

Re: how bout some pics of custom cold air setups
Nice work guys! Does the cold air intake make a noticeable difference, can you actually feel the difference! They all look very nice!

Re: how bout some pics of custom cold air setups
Looks good ...did you have to use bubble connectors of some sort on the ends, to prevent engine movement from cracking the tubing?
I am thinking doing a full fabricated polished aluminum setup and eliminate the flex tube. Spectre will weld and re-polish the tubing, after you cut, fit and mark all the pieces. Quote:
So just for an example, figure a under-hood temp of 180 degrees, and the ambient temp outside the engine compartment of 90 degrees. You would have a 90 degree reduction in intake temp. This example would give you approx 9% increase in HP, note there are many complicated variables which can vary this number involving calculating the exact air density. But it gives a good idea of the free horsepower to be had from a engine drawing air from outside the engine compartment vs. one which draws from directly behind the radiator Can you feel the gain?....... in ideal conditions it could be as much as 25-30 HP...... and vs. a non cold air system ....and that's definitely enough to "feel". |

What I have never understood is a cold air setup that the tube ends right in front of the motor and it's sucking the same hot air it did before. I just don't understand it.
I talked with a guy at a show who had a beatiful 68 camaro and his cold air ran down under the motor and stoped. No scoop nothing just a tube. I asked why he did it this way and he said it was the only way it would pull air in. Cold air isn't pulled in it's suppose to be forced in when you go down the road. That's why you want it to have an opening on the front end of the vehicle to have the free flowing air to be forced into it. I have the sheet metal covers between the grille and the rad support to help with this also. On a nice cool day you can feel a differance in the way the motor reacts. ![]() ![]()

Iv'e open my hood after running up to full temp and put my hand both inside the rad support and outside in the same place, down near the bottom. The temperature difference is substantial, probably 40-50 degrees, this is horsepower lost maybe 4-5 percent, vs. isolating the intake completely outside the engine compartment.

do you have pic, or link to these bubble connectors you refer to....I planned on making mine like yours, but I would like to pull the air from the cowl area

Re: how bout some pics of custom cold air setups
it's more commonly called a "hump hose"coupler...it give's the system the flex you need when using solid tubing

Re: how bout some pics of custom cold air setups
Dont have a pic of it with the hose on. I guess it's a cowl induction/cold air setup. I don't know how well it works yet.

Did you block off the vents inside to force the air back out the tube? ![]() ![]()

Re: how bout some pics of custom cold air setups
I have the vintage air kit inside, and the blower housing blocks that vent. I left the vent flap in, but sealed it shut. Judging from the past, there should be more than enough flow, even with the driver side vent open.

Here's a great read about "Ram air intake myths" ......not to be confused with "cold air intakes"
