Well I drive my car to the track and this wednesday I want to ice the intake down before I run her, and in between runs.
Its been real hot and humid here and I figure it can only help.

So my question is pretty simple - How long do you leave the ice on the intake?

you have a better chance of icing the air to cool it down....

you have a plastic intake. it doesnt heatsoak. icing the intake will do nothing for performance other than wet your motor.

so there is no point to icing our intakes? (stock ls1's - what about a ls6 intake - same thing?)

Guess i'll just get a new thermostat to reduce engine temps then.

thanks.

Yes there is a point. You're keeping the intake charge cooler. I've gained .1 from it, actually from keeping the engine cool.

The intake does get hot, icing gets it cold.

Do it all the time.

stock and super stock cars ice their intake

I never understood guys pushing their cars through staging, icing the intake,
then running 12's.
I can't imagine the intake still being cool after the burnout.

But hey, that's just me.

+1 i agree. after a nice burn out those temps are right back up

Agreed. When I run, I usually make one pass, then immediately make another one and the second one is 95% of the time better than the first. If there is a difference in power, I think it would be negligible.

I bought a product called the "racing cooler". It consists of (2) gel pack(s) that you freeze, and a nomex cover with velcro straps to hook to the fuel rails so you can leave it on the intake for the entire run. The gel pack is sealed and doesn't drip water like ice, so you dont drip on the track. I've been using it for two years now and the gel stays frozen almost all day without removing it from the intake at all. I'm not sure it improves performance, but it did make the car more consistant. It wasn't cheap, but the money I've won keeping the car consistant has more than paid for it!

lol, the responses are pretty funny.

I ice the intake, TB etc and turn the fans on to get the engine down to about 130-140 deg. By the time I'm staged the temps are hovering at 180 which tends to be the sweet spot.

You can criticize all you want, but the slips don't lie.

all i know is if the stock and super stock guys do it its worth some ET

well when your car is sitting the heat from the heads are rising back into the intake manifold and heat soaking it but once its running the intake will cool down because there is is airflow

case in point: i have the throttle body bypassed on my lt1 after you get done with a trip down the road you can pop the hood and the intake is cool to touch roughly the same temp as the steel tubing on my SLP intake

but if you let the car sit for 20 minutes with the motor off you can barely lay your hand on that intake you take her for another ride and the intake cools off but once its heat soaked it takes a lot longer to cool off the intake so when your at the track, one pass down the track in not enough to cool that intake back off so by using ice you can get it cool and it remains pretty cool (not too much above ambiant temp) until you shut the car off again

I have found that icing is worth betwean .05-.1 on my Stock Eliminator LT1's. I would have thought that the lack of heat soak on an LS1 would be a good thing (Stays cooler longer?). Don't just ice the intake. Pack the fuel rails and throttle body too. I use Zip-Loc bags to cut down on the mess. Don't remove the ice until you are at the head of the staging lanes.


Good Luck,

One of our better friends runs SS and Stock cars with us and he always ices them. Not sure what ET it's worth, he just does it for consistency... Even has some kind of old ice box setup for it. I don't see many of them doing it anymore though, we've never considered icing our intakes. I might give it a try some day.

As a twice-a-week drag racer with a big stall, I do 2 things: ice down the intake and spray the hole where the tc is with a sprayer and ice cold water. My whole jest is for consistant bracket racing, so if I do this every time the same and she cools down to 125* in 95-100 degree weather, I get 7.51s from her every time. (Yes, I call her a girl because I am a chick racer.) I guess it is just preference, but it works wonders for me and I never won money before when I never did it!!

I guess what I was trying to say is-
If you are running a heads up class, I guess it is worth the time, work, and money for ice.
Anything other than a heads up class...who cares? If you are running brackets,
you will be consistantly .05 slower.

I see guys doing it for time runs and it makes me giggle.

Ice is cheap enough, as long as you think your going faster who cares

I understand what jugger is saying, I have seen guys spend 1/2 an hour at the track placing ice under their hood, drag water all over the starting line and make a friggin mess for .005 on a 14 second car for time runs, wtf lol.

I honestly dont think the plastic LS1 intakes will matter much with ice. Plastic is a very good insulator..

yeah... thats gay.... unless you're in a nhra class or heads up its pretty worthless
