water/air intercooler... your take on EXPERIANCE!!

[whereda40at]

I have been in the process of building my drag car. I hate listing my modds everytime I post something like this. So to say the least, the goal is 8.90's on a borgwarner s366 in a 2.35 sr s13 hatch. I want to run a water/air intercooler. more than likely not I am going to run one, just want to see what others take is on experiance and maybe pics of how theirs is set up. I want to run mine with the inlet/outlet on oppisite sides so it can go straight from the turbo to the throttle body. Maybe if someone might have dyno charts or track times from just changing out the intercoolers would be great.

In my experience, the biggest key is to maximize total transfer:

That is, run the biggest pump and the largest lines you possibly can. Granted most experience comes through the diesel world, and or through the Ford world with CObras and lightnings, but the basis is the same.

FWIW: I also suggest that for whatever coolant box you choose, make it large enough to fit decent ice chunks in. THe worst thing is a small opening that forces you to spill ice everywhere.

Ok, cool. I have only seen one SR with a water/air and that was in I believe import tuner when they had a import motor build off. I pretty much want that set up for the intercooler but can't find the pic online.

frozenboost.com has some universal kits. Its pretty straight forward once you start looking into cores... If I could ever get over losing my front mount, I'm definitely doing one. There just better, it's science.

Obviously youre plumbing may be similar, but the key (as above) is the ability to store the most ice water, and then move it fastest.

I know most pulling and drag guys that I know or have helped setup end up using the Mezziere WP136...I think it's 20 or 25 GPM, which is PLENTY for most cars. Having spoke to a very prominent drag shop, they really believe in the A2W setups, but (and as I found out myself before he verified), you really need to kepe that ice water moving. I know people may think 'oh you want the heat exchanger to do the work', but the reality is you want ot keep it rolling...as in a 'small burst' setup, the ice tank does a good deal of work too.

Edit: Not a bad idea to wire the pump up independently, to keep circulating it in the pump with the engine off. Helps 'pre cool' everything.

Jason Rhodes (j_rho) did pretty much what you're thinking on his SM 240 a few years back. It's worth searching for. I don't know if he ever made a post here, but he did on Freshalloy. Some of his later comments were that the ice tank was a pain in the ass. He had to bring lots of ice, and had to find a place to drain it all the time. It's certainly a performance benefit though, being able to cool the intake air below ambient.

I really don't see it as a pain in the ass to maintain if you are just drag racing with it. Most people pull have the car apart in between runs to fix shit or change oil or what ever else. I was looking at them on Frozenboost.com. They look like nice kits. Think that is the company I am going to go with when I buy my kit.

It's just more shit to deal with. If you're already changing oil and other crap, adding another thing to worry about may put it over the top. Something to consider.

im not saying that i do. just saying thats what others sometimes do. i would only have to repack the shoot and put some ice water in and call it a day
