what the heck are you 3 going to be doing at TG's house????

connect a hose to the AC duct and route it to the CAI.

would the engine know what to do with such cold air..........would this be called an A/C Turbo GT500?

My car knows what to do with it when it's dry and 50 degrees out

actually, serious question. Could you actually re-route one of the a/c ducts to the CAI? I mean, I wonder if one could fabricate a splitter with an electric cut off so you could keep a/c blowing in the car when wanted, and when spirited driving in hot conditions is warranted, you could flip a switch to toggle it from cabin to cai? SS, you and I may just have to patent this if it could be done. Any concerns about air quality (I mean, I know we breathe it, but some folks smoke, so air quality for ourselves usually takes back seat to the car).

No it won't. At the time I got it, it was the only one I could find that didn't require a tune & premium gas.

I like that CAI for the GT though...I almost got rid of my C&L and went to that one...but instead I bought the Saleen series vi and the rest is history...

Aside from it not needing a tune, it also has less flow loss than any of the other CAIs because it eliminated the bends in the tube.

bump on this.....my mind is running around on this one....

I've been thinking about what you said. I think the first problem would be lack of enough air flow, but a different or larger blower could take care of that. The next issue would probably be ducting the air to where you want it. Depending on the size of the duct required, you could run out of room real quick, plus depending on the amount & degree of you bends, the losses will add up real fast. Your duct system valving would probably need to pretty air tight so you don't start sucking air from the cabin loop when it's not selected.

I dont see why it wouldn't work, I cant think of a better source for cool dry air.
you would sacrifice a lil cabin comfort
great test project for sure

1st the AC is shut off while in full throttle mode.
2nd it would never produce anywhere near enough airflow anyway.

An AC heat exchanger used in the air pathway would be interesting though as long as there would be minimal pressure drop.

I must not be driving it hard enough then. Haven't had the A/C kick out on me yet.

Oh, I guess maybe you were responding to my Turbo thought. That was more of a joke. But I would think there would be enough airflow to supplement the air going to the CAI from the A/C, especially if you cold block off the ducts to the cabin via a switch of some sort. It certainly would be cooler air than is coming in from outside the vehicle, right??

Duct work may be the killer here......I don't the know the guts of the car enough to know if there's even be room to get it there..........

It is possible, but how much money are you willing to spend? I've done duct re-routing on aircraft where we had to use several sections of non-round ducting to get past tight spots. Between design, analysis, testing, manufacturing & installation was about 6 months & several million dollars. Besides the fact that this was done on an airplane & not a car, you would probably have to mode the software in the car in some way. That can be quite expensive too.

Nothing is impossible. Some things just take longer.

Ford actually looked into doing exactly that (using the AC to pre-cool the air intake) during early development of the GT500. The net is that it's not worth it for several reasons...

If you leave the AC on (normally the compressor shuts off at WOT), the compressor's energy overhead soon outweighs the benefit after the small thermal buffer is depleted and if you turn the compressor off, you suck-out all the cold very rapidly (at 6000 rpm an SC engine is flowing serious amounts of air). They looked at thermal-buffering (chilled tank that could be pre-cooled via AC) that might be a large enough thermal buffer to get you through a good quarter-mile (with compressor off) but decided it just wasn't worth the expense/complexity.

I beleive this was back when John Coletti was Mr SVT and the Termies alrady out and the GT500 was in early planning. Read about this project somewhere back then but dunno where.
