would cooling my fuel have the same effect ( more btu per unit of volume) and help any.
In my drag racing days, we built a canister that hooked into the fuel line that had a coiled line in it that we could pack with ice for that very reason. This was a standard practice in those days (the 60Æs). Header wrap will also help with under hood heat.
