everytime I run my car for a long distance or a couple good races I get this odd "hot iron" smell coming from under the hood.I know it's not burning oil or burning metal due to friction but it smells like if you left a empty pan on a stove for too long,you know what I mean?It only seems to come from the driver side of the engine compartment.any idea's guys?
if it helps I haven't got my headers on yet still the log manifolds.

 

i had that problem too!
turned out to be the brake pad overheating due to excessive use it makes em have a metallic smell but not enough for em to smoke

 

i had an oder like that when i ran mine hard, i found out it smelled when didnt run a pcv valve
