You know, that container full of dry ice that the fuel line runs through.I have a Moroso one I got for 50 bucks. The guy helping me build my engine said that the cold fuel would help out at the drags with a bit of extra HP. Is this true? Seems like a good idea to me. My car is kind of wild, but not a drag car, more of a multi purpose racer, like a Car Craft Real Street Eliminator car. (My friend is a crazy pro street 68 Mustang guy BTW) Fuel System...
22 Gal Fuel Safe Fuel Cell
Mallory 140 electric fuel pump
Mallory Filter
Braided line, etc.

Most people use regular ice in them. Not sure how dry ice would affect the fuel. I know several tracks have outlawed the use of them as they tend to get water on the starting line one way or another.

And to answer your question, no I don't use one, not even back when my motor was on gas. I do know they help though.

I run one... It's an old MOROSO unit that is cork-lined inside & out. I wrapped it in aluminum to dress it up a bit and it works great for me! I usually put a 1/3 water and 2/3 ice in it. I insulated the line leaving the bottom of the can leading to the carb. It results in a constant temperature fuel being delivered & my carb stays nice and cool... it's much easier to change jets or adjust the floats when the carb isn't smokin' hot! I check the ice content as necessary. When the ice has all melted, using a paper cup, I'll dip out the water and add some more ice.
I drain the cool can when I get home and let it dry out; or else it'll get funky in 'dare. As KV says, you must ensure that the top stays on and that the water won't slosh out when you launch. Make sure when you add ice, that you don't spill ice down onto the frame,,, cause if you do - when you pull up the the box, the spilled ice will begin to melt and the linesman will send you back due to dripping water/melting ice.... Don't ask me how I know --  Good Luck!

Hmmmm.....
I don't seem to have that problem. 
Actually, my carb, spacer and intake "sweats" on the really hot days.

A friend and i had thought about a carb spacer that used the same technique with dry ice....may try fabbing up a box inside the gap in my air gap to see if the freezing cold air helps

Another good reason to run methanol as fuel.

Cool. I guess I will put it in when I do my fuel today. It should look like it belongs in the engine bay, even though it is blue. I might paint it red to match the MSD.Thanks.
I wish I could do a dyno test before and after. I wonder how much power I will get on a 470 HP 331 engine. 10 mabye?
