yeah it does not work when the car is moving..when its stationary, yes it works, hecne why you see the results on the dyno but never shows up on a timeslip.

Does it help to cool the intake pipes down between runs? Absolutely......how much? depends on the car and the setup I suppose. is it worth $400 + for these setups? Nope, not as far as I am concerned. Like I said if I were going to have a bottle in the car, there are FAR more efficient ways to run it than cooling the IC fins.....mind as well inject it into the engine as it should be.

WI I ahve no formal experience with, so cannot comment. I suppose its like anything else - there are good and bad setups.

Does your core get heatsoaked after 1 1/4 mile run - no, and ifit does, you have an inefficient intercooler, or its horribly undersized.

 

Exactly. Unless you are going to actually use the nitrous in the motor that's a stinking expensive way to try to cool your intercooler. No one here is making the kind of power that you should even bother considering something like that. Take the money and put it towrds getting internals done or get a progressive controller and use it to get your turbos spooled up a little faster and turn off with boost.

Also, n20 would be pointless at least here in Kali since you can't be driving around with the bottle hooked up regardless of if it's spraying the IC or feeding the motor. If you really wanted to spray cold gas co2 would be a whole lot cheaper and more legal to mess with but still, not worth the effort unless you want the car to be a dyno queen and loose out when you are actually driving.

You can get some water sprayers which will actually help since they will mist the IC and when the air goes over it and evaporates it heat will be pulled out so you really would see some benifit. For those in the desert think swamp cooler. That is how evo's and STI's are setup.

You can use something like this to build a sprayer for the IC for like 20-30 bucks. This setup can also do water injection but that's not really needed with the giant intercoolers that come with these kits. Or just get some high pressure misting nozzles and some line and just hook it up to the windshield washer pump and resovwair and turn it on manually. The link below incorporates a boost dependant switch.
