Last night I had a though about branching off a tube from my AC and redirecting it into my intake tube to pump it full of icy air. Has this been done or is called something else?

 

Ford had researched it to get an extra 50 HP boost for 15 seconds from their supercharged 4.6 and 5.4L v8s. They never put it into production. It stored the cool air and it acted as an intercooler until it got used up. It didn't duct directly into it.

 

Would it hurt the engine if I was constantly pumping my AC into the intake tube? The only problem I see from it would be that you get less AC in your cab and you couldn't turn on the heater unless it was just the defroster.

 

youd need some sort of metering device and coil and if you live in colder areas(not u being in ca) a sylonoid to shut it off in winter. even then youd want more a/c inside the cab and less to the intake like 80% inside and 20% intake. i think it could be done but who knows until you try

 

If you gained 1 HP from the colder air, will it offset the 5 hp the a/c is using to spin it? I'm pretty sure the a/c kicks off at WOT, but still.

One other point. Line up at a 1/4 mile track with the a/c on and they will kick you out of line. They don't want the condensor water on the track.

 

For one thing my truck isn't built for the truck and no way would I take it to one. You make a good point though on the loss. I dunno just a thought.

 

What little you would gain from having the cold dry air, will never make up for the drag of the AC Compressor. You'd still end up with a net loss of power.

 

Its a cool thought... no pun intended, but I agree with Wayne and Matt. The power lost will be greater than the power gained.

 

I think Ford already had that idea with the lightning and then they realized if the A/C broke it'd be blowing hot air into the intake or if the engine overheated it'd blow hot air into the cab.

 

how that would suck... still a cool idea man

 

the principle of cold air is valid.

I see bags of ice sitting on aluminum intakes between runs at the track.

Cooling the fuel line is an option also. Think about 40 degree fuel being sprayed in a fine mist, Its gonna cool the surrounding air. My thoughts in the past was to divert the purge spray of nitrous through a mini radiator for the fuel. It could be done with c02 cartridges also. All it would take is a small heat exchanger- a small copper pipe wrapped tightly around the fuel line several times. Pump a/c air, nitrous, or co2 through it. Add water and it would last a while. Run the a/c line through a larger pipe full of water. Wrap the copper cooling tube around the pipe. Heck, at that point you could just fill the pipe with ice water and let it do the work. I'm pretty sure Summit sells an ice/water fuel chiller bucket.

 

hmm good idea but it wont work

 

What power you make will probably lose via A/C...

Chemistry tells us that enegery cannot be created nor destroyed.

 

i almost did a snorkel from the a/c to keep water out of the engine. the problem i've heard from a neigherbor that did it, is that its REALLY LOUD inside your cab! it'd be a problem if it's your everyday driver. check out this link.
