"On hot track days I have run 100 oct. racing fuel a few times. I felt no difference. At $8/gal I probably won't do it again."
I get my 100 octane at VIR and it's almost 8.00/gallon there. I sure would not want to make feeding the car that fuel a regular thing, even if I find that there is a little bump in performance. But for me, it just gives me a little more information about the potential performance envelope of the car. Such is the nature of the hobby,
