Well now that you tell me the inside of my pipes will match the outside Hot Jet Coating, then I must get a hold of this racing gas! That sheds a whole new light on it since my 429 SCJ never gets hot or pings, of course I'm not racing at 120+ MPH down Texas backroads either!
Actually, the Shell down the road sells 3 different octane levels of race gas as well as leaded gas for those folks with non-stainless valve guides and seats, oh and for the two-stokers.
Now, I will disagree with you on the plain old race gas smell being the best.... The BEST smell... is 116-octane leaded race gas, with Red Line 2-Stoke Racing
Oil mixed in it, to top this off it MUST be whiffed while located at Washougal Motocross track with my RM 250 cranking about 55-hp in between my legs doing big air on the table tops. Just like the Cobra power to weight ratio, but lots more suspension and I can even scratch it without crying!
I even run the pre-mix stuff in my lawn mower when it gets old for the great smell and memories it brings!!!!
