Bought a five gallon jug of leaded 110 octane "VP" brand racing fuel. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)
My motor seems to have higher than stock compression. Lowest is 160 PSI. My speed shop guy says the valves will like the lead. (IMG:http://www.914world.com/bbs2/html/emoticons/chowtime.gif) Maybe I just like throwing money out my open windows at speed... (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) KT |

One also shouldn't generalize and say things like "high octane burns slower". It *may* burn slower, it may not. VP 110 racing fuel very well may, but some other 110 octane fuel might not. Octane measures detonation resistance and nothing else. It does not measure flame speed, viscosity, energy content, color, taste, smell, or anything else. There are so many different compounds involved in what we call gasoline that there are no hard and fast rules about any property of higher octane gas other than it's more resistant to detonation than lower octane gas.
Even pump gas varies substantially from state to state. Pump gas in California, for example, is refined in California for the California market. It's not used in any other state unless someone buys a tankful and drives somewhere else. I'd not be at all surprised if Jake ran an engine on CA gas, he'd come up with different results than he gets with GA gas. |
