somewhere i remembered hearing that cooling your fuel can give you noticable gains... is this true? i have been thinking of taping into my fuel line and routing it into a (aluminum)box containing a spiral coil and then while at the track, just add some ice in the box (around the coils) to chill the fuel. or if i end up getting that ZEX kit, possible purge some into that box. anyone TRUELY know if this is a worth while project? thanks in advance.

At one of my local car shows a few years ago I saw a muscle car with a setup like you descibe for cooling the fuel. If I remember right it looked like it was comercially made so perhaps you could buy one. But even doing it yourself it would probably be very cheap for materials, mostly it would take some of your time. I think dry ice is colder than regular ice and threfore more effecive. Also Regular ice may drip onto the track when it melts, possibly causing you to be disqualified.

The amount of fuel used compared to the amount of air is very small so I don't see it having a huge effect but I am just speculating. This should be relatively cheap to do and it should be very easy to do back to back runs with and without it to see what benifits it has.

A quick search on google and I found fuel coolers that look like radiators - http://store.summitracing.com/produc...earchtype=ecat

And a company that makes Ice packs designed to go on the Intake manifold and wrap around a fuel line - http://www.racingcoolers.com/

 

Cooling the air charge is MUCH more effective than cooling the fuel. Also, dry ice is a BAD idea, since as we all know it is solid carbon dioxide. As it sublimes (turns directly into gas) It would fill the engine compartment w/ co2. Obviously a bad idea. Plus, the EXTREME cold (-109.3F) will freeze any and all moisture (water) in the lines.

 

Is there an effective way to cool air that is flowing at ~260 cubic feet per minute without impeding the airflow? (Well, we know nitrous works pretty good , but other than that?)

Would the small amount of dry ice we are talking about release enough Co2 to cause a problem? Hopefully you don't have any water in the fuel lines anyway. I knew dry ice was cold, but I didn't know it was that cold

 

Cooling the fuel on a 4th Gen wouldn't help much if any, you are basically circulating the fuel from the tank and back again for the most part so it is not heated up in the engine compartment.

Now if you had a carburated car it would help some and the design of the 2k2 and up with the returnless system is very poor design to save a few bucks. The fuel sits in the fuel rail until its used and it can get very warm.

Here is a primer if you are interested.
