Keeping Car Cool Tips

I take my v6 to the drag strip pretty much every weekend. It runs a lot on some and barely any on others. Anyway, the v6 has a tendency to get heatsoaked fairly easily. Example of this is that I always run my best time on the first run of the day after I let it sit for 45 minutes after getting to the track. I have an intake manifold insulator and it helps a lot! (compared mine and my buddies v6 and mine was a lot cooler... Thinking about taking actual temp reading) Anyway, I wanted to know if you guys had any tips as to making the car run cooler or helping it cool down faster? I willing to try anything as long as it won't hurt my car lol.

my last car i had.... i actually had setup a CO2 purge system inside the engine bay(6 puring nozzles)....after a run in the staging lanes.. i would spray. dramatically reduced my egine temp... i would say 50 deg or better.

Would that hurt the engine at all? How expensive was it?

I saw people putting like ice packs on their intake manifold, would that cause damage though?

I've seen guys buy 12volt fans and run them off of the cigarette lighter while in the staging lanes. Just pop the hood high enough to put the fan (use it like a prop rod). Looks like a small box fan or squirrel cage fan.

no problems at all.. ran it for about 4 years...cost me about 300$ for parts... installed myself.....similar setup as N02 purge kits.

opening the hood helps too

cool down

As soon as you get through the 1/4 mile and are in the return lane put your heat on full blast, when you stop at the pits watch temp gauge at idle ,with heat on.....if you really want to get cool quick get an electric water pump...problem is there quit expensive for Camaros..

Running the heat? Hmm never heard of that one! Anyone want to explain how that works? I'm intrigued now

the heater works by taking heat from the coolant as it passses through the heater core. Blast the heat, open the hood, push the car through the staging lanes, etc.

ice wont help as much as if you had a metal intake like carburator cars, ours is plastic, don't waste your time with that one.

otherwise, wait for fall/winter like the rest of us. going in the summer is CRAYz!!! too hot man.

another thing you can do it rig the fans through the fuses to stay on even with the car off. you can link two fuses with a wire and keep them on.

Wire in a switch to run your fans manually, or get a tune.

I have a tune, what should I ask for? Should i get a drag specific tune that I only use for the strip?

You could always try running a cooler thermostatlike 160. Don't know what you are running now but that would help keep everything a little cooler cooler. Plus sounds stupid but while your waiting you can always run the a/c, that will make your fans come on no matter what the temp is when the compressor is engaged.

You want the fans to come on earlier in the tune. Mine didn't come on until 219 with a factory tune.

High intake air temps(IAT) causes detonation. So when the engine sees KR, it will pull timing and slow the car down.

Like John said. You can also wire the fans up manually and turn them on them you get to the track if you dont get it done in the tune.

A lower thermostat will help some, but not much once it gets heat soaked.

Last option would be to turn the A/C on after your off the track. Best to have a catch can on the evap line so you dont get any water on the track. Once the fans run for a while it will cool down the coolant and stay cooler longer.

Could also use a water wetter and it may drop 5-10 degrees.

My SS will slow down .4 based on coolant temps in the same day.

That will get you thrown out of the strip where I go. Not sure why. Maybe water from the evaporator dripping?

It doesnt take very long for the water to stop once you turn the A/C off. maybe 30 second?

Couldn't you just relocate your IAT sensor to somewhere lower and out of the way on the car that won't get as hot as everywhere else?

Hey Josh, I'm getting my car tuned Wed along with bolt-ons. I'd really like to pick your brains about tuning the fans and IAT/timing. I'll send you a pm.

I have never messed with a 5th gen before so I'm not sure what's going to work best with the fans but I'm going to try some stuff, I hate how hot the car gets before I'm even at the line. If I don't have to wait not as much of a problem, but to run a class with long lines I need a solution.

O you could also look into getting hex vents, those are suppose to help let heat escape
