hey this is a serious question i was thinking about at work tonight... could i reroute my AC compressor to push cold air directly into my intake and get some type of forced induction gains from that?

You can laugh at it, but the basic idea has some merit, if you don't want to use the A/C for cooling. Execution of it is extremely complicated, however.
You would need some kind of pressure regulation to avoid excess pressure. That takes custom hardware that has to be fabricated.
You would need to know how much to limit the pressure. Turbos range around 7-14 psi boost, and too much will blow out gaskets and stress valvetrain parts.
It does seem like a cool idea on the surface. But you really want an engineered solution, which....is called a supercharger! Hey!
But they can cost $3,000 or so (because it's complicated and not a high-volume market).

i don't think that little compressor would give enough volume out to build any boost. and those things can put out at or near 300 psi.
i have seen people convert a/c compressors to be just air compressors. they make great low volume hi pressure compressors.

Yep, you could have 1000 psi and it wouldn't be sufficient to improve engine performance. Both volume and pressure have to be matched to the application.
A large fan can move large volumes of air but it does so at very low pressure. A pump can create high pressure but have very low volume.

LOL that was funny. And the last two guys are correct.
The A/C compressor builds pressure compressing the gas into a liquid in the condenser and 3/8" liquid line which then hits a restrictor at the metering device going into the evap coil. The restrictor is like making it push that liquid through a hole no larger than 1/8" that is one reason it builds pressure in the first place. After the restrictor going back to the SUCTION of the A/C's (air pump) it drops pressure around 40 PSI and your liquid refer evaporates to a gas as it is warmed through the evap coil. Back to the comp almost all gas, but the proper pressure and COOL GAS is what cools a compressor.
Using it for an air pump from atmospheric to a tank would work as an air compressor but the compressor would get HOT after a while that way and no lubrication.
ANyway, there would never be VOLUME = 600+ CFM so it would never have positive pressure if piped to the throttle body.
Now. If you mean to use a working A/C system to chill water which would then feed to a water to air cooler that could drop teh air temp going into the engine, THAT may note a few HP.
Ford was supposed to do that for an extra intercooler for their supercharged 5.4 in the Lightnings.

i think i have an idea why Ford didn't do that. if you cool that air down too much, wouldn't the moisture drop out of it and you'd also be forcing that water in there also? maybe not much more than a water injection unit but.
on second thought, that might help with detonation on a S/C or T/C motor.
Things that make you go Hmmm.

Interesting, but yeah I've heard of people injecting water/methanol which I'm considering for my ATV turbo project.

for serious boost, 20 psi+ i think you'll want water /ethanol or methanol injection.
if you want some good info on turbo charging take a look @ www.turbobuick.com. you have to register but, no charge. these guys are serious when it comes to turbos. i found that site when i started doing some research for my Buick project. '78 Skylark 2 dr and haven't decided yet between a Buick 455 or an '87 3.8L turbo.
and no matter who's engine or turbo the mechanics or principle's are all the same.

LOL well I think we took the thread off of topic. He was asking if an A/C compressor could be used AS a turbo. LOL but anyway you are right. Principle is the same.
Since we're off topic and he never came back...
THAT is a Turbo on my 350cc ATV I am modifying.
It's a little turbo. Bought it new.
You can see all of the pictures here---->

So, I have a Yamaha 250 Timberwolf I'm wanting to
use the same T15 turbo on... I'm wondering about
where to get the oil supply line from, and I'd
love to see more pics...
The pics like you have is down, I've searched and
searched and found all your posts but they all
lead to the same dead links..
Is there any way you could get me your pics?
Thanks!!
