Q:
Has anybody seen those can coolers that you can put in the freezer that are filled with the blue stuff? Would it make sense to put a couple of those on the cold side of your IC piping before you ran a 1/4 mile or for a dyno run? I've seen a couple brands that are velcro so it would be easy to wrap them around and you could keep a cooler full of them and replace them as they melted.

they would block air flowing through the intercooler. now if you had a water to air intercooler,sure!
If all were equal, none would be strong.

A:
I think he means wrapping them around the IC pipe that feeds the throttle body. It would probably provide minimal gains. The flow doesn't interact with the pipe walls as much as the fins in the heat exchanger.

Many guys with turbos, and superchargers lay a bag of ice on top of their units to cool them down for the next round when at the track. If you can get a cool charge of air into the motor, it might make a few more ponies.

what about the engine mats, those sleek fans you set on the ground to blow cool air up the engine?

Yeah by cooler I meant like a little lunch box, not my intercooler. I guess that makes sence of how the amount of air that was actually touching the pipe wouldnt be much of the volume.

A:
It wouldn't hurt your horsepower, but it would start adding significant weight. I know a couple guys who wrap the more pronounced bends in their intercooler piping with ice or that fluid you are talking about. If anything, it keeps temps down a little.

Water to air intercooler is the only way to achieve what you are talking about. You add a bag of ice before a run and it's like you driving in December with a -10 temp.

S30 one of these days I will get around to putting it all back together.
A:
they used to do this in the old days of carburators. lay ice on the fuel lines to cool it down as it entered the carb. dunno what kind of gains it gave them, but i know they used to do it, sounds similar.

A:
In the "old days" there what was called cool cans. It was a can about the size of a 2 lb coffee can with coils inside that the fuel ran through just before it went to the carb. They worked well but if one used dry ice and shut the engine off, it would freeze the gas. Been there, done that.
A:
So with the water to air ICs does it use engine coolant? I have thought about this and have never understood how it would flow water unless it was plumbed intot he engine but then the water would be hot as hell. Or is the air on the hot side of the IC alot hotter than I thought. Is it like 200+ deg.?

A:
Water to air intercooler has it's own seperate water reservoir mounted somewhere else on the car. That water is then circulated and oftentimes there is another "radiator" for the intercooler water.
A:
i put a coffee can on my 70 challenger, it had a hole in the bottom big enough for the fuel to enter and a couple more holes to allow the water to drain. the fuel line made about 8 coils inside the can about 1 inch from the sides . before a tough race i would fill the can with regular ice. the fuel line came out the top and straight to the carbs. the general idea was that cold fuel mixes and burns better.this car was so fast that im not sure it helped or not. We need a scientist here to verify that cold fuel does mix and burn better to get a difinite answer.

A:
i forgot to add that to cool the fuel in your line you would need to cool about 10 ft of line to make any effect on the gas. a short distance being cooled would probably have no effect because the fuel would be moving to fast.

I'm looking into water injection now. I have all winter to get my engine tuned so I might mess around with that.

A:
For the initial question about wrapping the intercooler lines, I think it would create moisture in the line that would be sucked into your engine. Might not help as much as you would hope either.

water injection is a bad idea. search the tech forum for "water injection" and "copper leeching" (or is it leaching?) anyway, this was disccussed at some length a few years back. some people said it leeched the copper out of the aluminum alloy the head is made out of (Lseries) and left it looking like swiss cheese. Maybe Ethanol or Methanol is a better idea?
I know Im starting to look at E85 as a means to have a light pressure turbo on my 11.5:1 motor.... :D

Never used their stuff, however, I have seen something similar to the intercooler spray bar, but instead of CO2, the guy used NO2. Nitrous, like the stuff you use as a power adder, but he was using it to spray his intercooler.
No kidding, this added 60 HP TO THE WHEELS! No additional mods. Now, this was a relatively modified TT350Z, but 60 f'ing HP?! I knew theoretically it would improve things, but not to that extent.
NO2 is a much colder gas than CO2, so it'll cool the charge going through the intercooler even better than the CryO2 systems. Unfortunate side affect, NOS is a LOT more expensive than CO2 from your local welding supply store... ;(
Oh, and the spray bar wasn't correctly sized for his intercooler either, it only covered the top (most important) half. They put it together as a proof of concept. Once he gets another spray bar to cover the bottom half of the intercooler, it'll be interesting to see how much additional improvment it'll make.

absolutely retarded to just vent it into the air when you could be getting the cooling effect at 100% efficiency as oppsed to a stupidly low number, as well an an oygen rich environment directly into the engine. Only excuse would be competitions rules or something, which would still probably ban n20 use in that manner, because I would happen to place my intake behind the intercooler.
A:
Hey, I didn't say it was a smart use of N20, I just said it was amazing the difference it made. A 50 shot of nitrous without putting it into the engine for cryin' out loud! ;)
Like you, if I were going to go through the trouble of plumbing that system I would have the spray bar inside the intake charge too.
Actually, I would use CO2 to spray the IC and the N20 to have fun!
Or, do a two stage nitrous system with the first stage into the intake to spool the turbo and get the boost up and the second stage to spray the intercooler!

There is a pretty famous AudiTT that uses the NO2 spray on the IC and it puts out a redonkulous amount of power. 750ish if I remember.
