Cool can??

First, I am a bracket racer not a stocker so don't have to play by all your rules.

I run a cool can (acually a small cooler with a heater core in it and yes i did check for any flow restrictions

) on my return line right before my cell.

Did the math and mounting it up front , the cooled fuel only lasts about 100 feet down the track, after that it is traveling too fast for any real heat exchange.

Did more math, with a 8 gallon cell, if I run just the fuel pump (car off) I will get one complete exchange every 3 minutes.

Run it for 3 minutes in the pits, all fuel get cooler, then driving to the staging lane takes atleast 3 minutes, another exchange,cooler yet. Then staging etc , you get the point.

A side benefit of running it threw the system/return is everything acts like a heat (cold?) sink gets cold, fuel lines, fittings, reg, carb.

I raced 2 races, one was great air etc with no cooler. The other was brutal 165 degree track temp in thin air. Everyone else was off by 2 tenths, no B.S. , I was a tenth almost 2 quicker.

Take it for what you will.
