UglyButFast63 Posted January 26, 2004 Report Share Posted January 26, 2004 My shee is bored .080 over (not sure of the size of the domes) with DG pipes and silencers. I started running 115 octane race fuel through it about a month ago. I mix it half and half with 93 octane because that's what a guy told me to do. My question is whether or not I can run straight race fuel without having to mix it with 93? Or will it burn too hot? I am also running hotter burning plugs too. Thanks for any info.

Just for fun Posted January 26, 2004 Report Share Posted January 26, 2004 What is your compression? Thats the deciding factor of weather or not you even need to run race gas. The bore has nothing to do with it. Also, your elevation and dome size will give you a ballpark figure on weather or not you need it as well. Give us that info and we'll be able to square you away.

jasonsb Posted January 26, 2004 Report Share Posted January 26, 2004 Two things: Can you run race fuel and not have any problems? YES Do you need to run race fuel? You need to know your compression and mods just as stated above. Quote Link to comment Share on other sites More sharing options...
Ducman Posted January 26, 2004 Report Share Posted January 26, 2004 You wont have any problems running straight race fuel, it actually doesn't burn "hotter" it has higher octane to prevent detonation. The domes in your banshee are probably small resulting in higher compression requireing a higher octane fuel so you wont have a detonation problem. Also unless I am missunderstanding what you mean by a "hotter" burning plug, I think you are refering to the heat range. You would be better off with a stock, or colder heat range plug. The spark produced by the plug is the same for each heat range Br 6,7,8,9 ES the difference is ammount of heat the plug retains in the spark plug's body and insullator tip while under operation. A colder heat range plug will foul easier because it won't burn the carbon off and "self clean" as easy as a hotter heat range plug, but a colder heat range plug will help prevent detonation because the colder plug won't prematurely ignite the fuel as easy as a hotter plug and the head actually cools off easier. I would recommend to just use the stock heat range plug. Quote Link to comment Share on other sites More sharing options...
