I know that keeping the ac belt on drains a little hp from the enging (parasitic loss i think it's called), but lowering the intake temp increases it, so my thoughts were this, reroute the ducting for the ac to the cold air box and use the AC to cool intake temps, etc...now the bigger question is would it work and if it did, would the gain be more than the parasitic loss!?



yeah i am trying to sound all intelligent like :P

I dunno, I know my AC just hammers my "get up and go" sometimes I play with it while accelerating and it's almost like the turbo spooling in when I turn it off.

ROFL, maybe i should hook mine back up... https://www.nopistons.com/forums/pub...R#>/tongue.png

why dont you just do the water injection mod that zerobanger posted

cuz then i'd still have pieces of AC that have no use https://www.nopistons.com/forums/pub...R#>/tongue.png DUH! :P

heck, just give it a shot! All it would take for a simple experimental setup would be a air box around the filter, sealed really well, and some cheap tube running from one of your a/c vents ("why do you have a bunch of duct tape on your dash?" "oh, no reason...")

I've heard of some newer car that does that...or maybe I'm crazy. The newer A/C systems don't drag down the engine nearly as much, if at all, so I'd think there'd be some gains to be had on a newer car, but it wouldn't hurt to try on your FC.

there's a new truck with a supercharger that uses that. I don't think it actually blows cold a/c air in the intake, I think it runs the intake air by the same kind of thing that cools the a/c air. I'm not hip on a/c components, so I'm not sure what makes the air cold, but I think that's what they use. Does that make sense?

Yeah, I should have been more specific. It doesn't force A/C air into the engine, it just cools the intake air. I guess I'm not so crazy after all.

mabye try piping it around the pipe...like a cooling duct around the pipe...



it may restrict flow and cause wierd flow charistics(sp?) at idle ect when the AC is forcing cold air into the engine...just a thought

why not cut a section of PVC larger than your intake pipe, and pack it with ice? I started typing this as a joke, but now I'm wondering if that would work....wait, dry ice!!

The AC may cool the air 30-40 degrees max over ambient but by the time the air makes its way into the engine, thats even less so I can't see how having your AC on to do this would give you any power gains... not trashing you at all though, its fun to be creative.



When I used to drag race many years ago, I'd go with my cousin's redneck buddies who had their fuel lines coming into the engine bay and running through a cooler packed with ice and of course packed ice bags on their intake manifolds. Cool fuel? not sure if that's an old trick that works or just people thinking it helps.

wow, I can't believe I actually thought of an idea that actually works, that people already use. Heck, it makes sense, and I'm kinda rednecked.

well dot they have IC's surrounded by an ice box?? im sure ive seen them.

I have run fuel coolers on a few of my past race cars. Dropping the fuel temp makes it less prone to vapor lock. Caused when the fuel in the lines gets too hot and turns to vapor. Causing a "bubble" in the fuel lines, and making the car cough when it hits the engine.



You can actually buy fuel coolers, for just after the pump.



As for the AC, rather then route it to make it cool the air, why not rip it all out, and call that "weight reduction"
