jrm312 Posted April 1, 2004 Report Share Posted April 1, 2004 it all depend on your elevation and compression anything over 155 to 160 you should run 50 /50 race gas and pump, but i no expert do a search on it here you should find the answer, i run 22 domes at 145 compression and im fine with 92 octane.

AVBANSHEE03 Posted April 2, 2004 Report Share Posted April 2, 2004 USUALLY 155LBS IS BORDER LINE PUMPGAS, MORE THAN THAT UP TO 160 YOU SHOULD ATLEAST DO HALF/HALF, OVER 160 YOU SHOULD RUN STR8 HIGH OCTANE.. BETTER PERFORMANCE TOO, YOU GET WHAT YOU PAY FOR. LIKE JRM SAID. Quote Link to comment Share on other sites More sharing options...

Travis's Banshee Posted April 2, 2004 Report Share Posted April 2, 2004 Ducman: Where do you get your race fuel? I lived in Red Bluff from '90-'00. We used to buy I believe it was K+S race fuel up on the NE side of Redding. The guy had a smokin' shee w/a 750 4cyl. in it. Was just wondering if it was from the same guy. Think his name was Dennis. I hadn't bought fuel from him since about 96-97 when S+K in RB started carrying VP. Just curious thats all. Quote Link to comment Share on other sites More sharing options...
AVBANSHEE03 Posted April 2, 2004 Report Share Posted April 2, 2004 Higher octane doesn't give more power. I SAID PERFORMANCE.. NOT POWER. IT BURNS FASTER. Quote Link to comment Share on other sites More sharing options...
