Now I`m a bit confused and don't want to hurt anything and I street drive w/91 Shell sometimes and wanted to race w/av gas so maybe I'll stick w/the 101 VP-101............
your not gonna hurt anything trying it maybe just your pants pocket you keep your wallet in.like the other post said go check out yellowbullet tons of guys running it with good results.it also dosent change my tune at all from c12 or sunoco112 or anything else ive tried non-oxygenated only when i run q16.airplanes take off at sea level so the altitude thing is BS.....they have way more load on them at take off.
Well, I live at 5000 ft above sea level. We have a great 5000 ft runway at our airport. Most of the planes that frequent our airport are powered by air cooled engines making about 2-300HP ( at sea level)- not 6-700 HP. Got plenty of air running over the engine and related fuel system on the ground. I also belong to the local car club ( also at 5000 ft above sea level ). Most do not run Av gas. Those that do, run a pump back by the fuel tank to keep the fuel line pressurized - to prevent vapor lock. Obviously KOS has never experienced this "phenomenon" and just blows it off as BS. Rooky! Did I mention heat soak problems when running Av gas? If you think E10 is bad, let me know how long the crank time is with Av gas sitting in them float bowls - or should I say - aint sitting in them float bowls after the carb heat soaks for an hour or so.
ive been running av for 30yrs never experienced any vapor lock valve seat issues etc....have you ever run it?? if you dont have first hand experience with it dont come to conclusions from what you heard.
