SiCkBaNsHeE_990 Posted February 21, 2004 Report Posted February 21, 2004 I have been wanting to start running 110 octane race gas but i need to know if i have to change anything like jetting or something like that? or can i just put it in and go? Quote
SDD Posted February 21, 2004 Report Posted February 21, 2004 Only run it if your mods indeed need that much octane other wise your just burning your money away. Quote
SiCkBaNsHeE_990 Posted February 21, 2004 Author Report Posted February 21, 2004 like what mod would you run race gas with? Quote
MRMOONEY Posted February 21, 2004 Report Posted February 21, 2004 COMPRESSION, IF YOU DONT HAVE AT LEAST 150 LBS KEEP RUNNING PUMP GAS, OR WASTE YOUR MONEY ON RACE GAS. ALSO JUST TO LET YOU KNOW AV GAS IS ALOT CHEAPER THEN RACE GAS AND IN MY OPPION WORKS JUST AS WELL. Quote
Wassup350 Posted February 21, 2004 Report Posted February 21, 2004 Definitely run it if you have high compression. My friend ran 87 in his 800 with high compression heads and blew it up. He messed up the cylinder wall and the piston. Quote
boonman Posted February 23, 2004 Report Posted February 23, 2004 You don't need it unless you have a higher compression engine. It will be a waste of money. High octane fuel is designed to withstand high compression and not detonate, or pre-ignite. Quote
Wallrat Posted February 23, 2004 Report Posted February 23, 2004 Yup, higher compression and also advanced timing will require race gas. He guys, don't you have to run cooler plugs with race gas? Quote
boonman Posted February 23, 2004 Report Posted February 23, 2004 don't you have to run cooler plugs with race gas? Never heard anything like that before. I have found that the stock heat range has always worked best for me. You definitely don't want to go hotter, but it is always a good idea to watch your plugs carefully. They are a good indicator of how things are running........ Hotter range plugs can lead to and/or provoke detonation and pre-ignition problems... Quote
Rescuejeff Posted February 23, 2004 Report Posted February 23, 2004 I have found by mixing Avgas and super unleaded gas it has a performance style range with a poor mans budget, It tends to run a little cooler, but not that much, but has a the instant response parts you want out of the race gas. I go 50/50 Av to super. Quote
