Race at Track with AC on or OFF

[Little6pack]

Ok this is a crazy one!

I was discussing this with a buddy.
He was saying race at the track with AC on in a turbo car because the condenser will be cold thus cool air will blow through the IC if you have the Stock mount IC.

I have heard of someone using the AC to Duct cool air into the intake.

OPINIONS?

When you go WOT the ECM turns off the AC pump.

[ghall]

Racing at the track with the AC on drips water all the way down the track--that's a big no-no

Never take advice from that friend.

The condenser is there to put the heat into the air that flows through it, not take it away.

Since he is your friend I will be nice.

Quite literally the funniest thing I have heard in a long time. Please invite him to this forum so he can explain just how that works.

condensor up front gets hot the evap in the hvac box is what gets cold.. He's a$$ backwards lol

Is your friend the same one that thought he could port his intake and heads by letting the engine ingest sand?

Even if this was true , By the time it gets to the stock IC it'll be hot cause the radiator used up all the cool air

+2, with a friend like that who needs an enemy

It's a heat exchanger that takes the heat out of the super heated gas and CONDENSES it back to a liquid state. All the heat that is removed from the condenser gets sucked throught the radiator causing your car to run hotter with the AC on.

And when the hot ambient air that blows through the cold evaporator, the moisture in the air condenses, dripping water down the track, which pisses off officials and everyone behind you.

And yes, the compressor kicks off WOT.

You should tell your buddy he should try an electric leaf blower as a supercharger. That is where the real power is at.

Hahaha, I like the leaf blower thing!!

Hey now, I thought direct exhaust injection was the new thing??? You know, where you route your exhaust gasses out of the manifolds right into the air intake, sort of like a forced naturally aspirated induction.

Now they even have an intercooled version of it. See below:

Yeah I knew it was hogwash when he was saying it. I did not want to burst his bubble he is one of thoses KNOWITALLS & doesn't even have a turbo car.

You are better off to just agree with him when he is usually wrong But thinks he is correct.

One good thing about new england is we don't need the AC period. So the cool air temp will help when racing.

15 years ago at the track there were guys sitting in the staging lanes, idling with their A/C on.

When I asked what they were doing, they said "cooling their car off".

I had to ask "How?"

Well, you see, when you run the A/C, it turns on the electric fan and that cools off the radiator.

Ohhhh....

[KevinB]

You are better off doing it this way lol. Just point the a/c vents to the air filter

I run with the heater on full blast in my Talon!!
You'd be surprised how much it will drop temps, but the GN never heats up and well, I no longer have it anyways.

That might be what he meant, and if not, tell him that's what he probably meant to restore his ego.

That works if you dont have the fan wired to a remote switch. The problem I always had was that I could never tell what the coolant temp was. Bone stock car meant no remote fan switch and no temp gauge. It's an old factory engineer trick that works rather well if you ask me.Now the big question I've always asked is how much? Is a car that is at 165 any faster than one at 185 or 200 degrees?

I did this when I did the last Rev It Up at Disney World. They would let those poor Cobalts idle in the staging lanes. I'd climb in and see 210-220 on the temp display. I turned on the AC and watched it go down to 189 or so and than climb back up to the 200's and than back down. Kind of weird on how fast those cars would lose 20-25 degrees in the span of a minute or so.

The Car in question was an otherwise stock 5.0L mustang, and no it won't be faster Idling for 10 minutes with the A/C on than if you shut it
