I race all of my and wifes cars. Wifes 13 gt was tuned with 93 pump (e10). Mine are all around 10.5-1 motors. I also race the pro street car with 93 up to 150 shot. Just wondering which was better? We have both the 93 or 91 nonoxy available. Thanks much

I mix 4 gal of 89 non with 1 gal of Cam II 110 and get 93.7.
Easier to read plugs and tune up. Has lead with the 110 and No ethanol. ;)
