The board has been kind of dead in the lancer forum so I just thought of an idea to start some conversation. Just wondering if its possible to route the air conditioning lines through the throttlebody where the coolant goes through. It would cool down the tb and intake temps when you turn on the a/c. Please dont flame on this.... just wanted to bring up the possibility if this could happen. The only thing I would be concerened about os the possiblity of leaking through the lines where you connect it to the tb and how to connect it. Any other thoughts?

 

the extra pressure may be harsh...with mad condensation

 

I assume the gains would be minimal if not doing the opposite of what you're looking for since the AC rubbs off quite a fair amount of power when you turn it on. Unless you'd only want to cool down the TB every once in a while which would kinda be point less since it would get hot again within seconds.

 

Well I personnally think that cooling the throttle body would not be as effective as maybe cooling the intake manifold. But then once you start useing you A/C lines your a/c will not be as cold because of the direct heat and on top of that you are already robbing your car of energy by using the A/C. You may be able to minimize the A/C power robbing effects with an undersized pully but even then i dont know if they make one.....Just my .02

 

How bout buying an IM spacer, assuming someone would make one for the lancer's 4g94:

I would say the best and cheapest thing I did to my car was a 4G93 IM noticible gains for under 100 bucks. Now I dont think you could fit a spacer on the 94 because the IM is soooooo Big it would prolly hit the fire wall....

 

it's only 3/8" thick, im sure we have enough space back there to afford 3/8"

 

what is an IM spacer...not to sound stupid...though I know I do

 

It is a gasket-like thing made of a specific material that blocks the transfer of heat. The intake manifold is what runs the air into the combustion chambers in the head of the engine (which gets pretty damn hot). In turn the heat would normally transfer to the IM and that would heat up the TB and that would heat up the incoming air. The spacer stops the IM from getting hot thus allowing a cooler flow of air into the engine. It doesnt yield much power but it does help a bit.

 

And yet, I'm beginning to believe that they'll never release it. It's been "almost ready" for a couple weeks now...

 

there may be 3/8" in the engine bay- but what about the bolts to hold the IM on- and the two studs on the ends, are they long enough?

I think the gains from rerouting would be minimal. That's provided that nothing leaked. Since releasing refrigerant directly into the atmospehere is a federal crime, I don't think I'd be trying this anyway, as often as I take off my IM and TB. Notice that all of the underhood lines for the AC are solid tubes. I'm under the impression there is some pressure there and they at least did it that way for a reason.

 

I thought R-134a was considered environmentally safe. Hell, I had to vent my entire AC system when disassembling my car a while back. I dunno what you meant exactly by "solid lines", but some of them are similar to fuel line, nylon-reinforced rubber hoses (such as the ones on the compressor).

As for the original question, as others have commented, it'd be a waste of time and effort. If you want to cool your coolant more efficiently try some sort of air to water heat transferring device if you want to lower temps. Either way is a bit of waste though if you're not constantly overheating, because your car was designed to operate at certain temps (I don't remember them offhand, but I want to say around 110-170 degrees C).

 

interesting idea...

 

You would have more gains from changing your belt to skip your AC pully. And even more if you just removed the system.
