[QUOTE="gwcrim, post: 1338732, member: 35528"] OK.... many years ago there was a series of articles in Super Stock and Drag Illustrated penned by Bret Kepner under the ghost name of 'Dr. Dirt' if I recall correctly. Bret is a very talented drag racer. He documented how he could use a rent a car in a bracket race and win over a full out drag car. I mean, he had it down to knowing the amount of time he could scrub off by drifting the car from the middle of his lane to the outside. One of his tricks was this: If he needed to slow a few hundredths in a race, he would take a bottle of octane boost and add it to bone stock street car. His assertion was that the fuel, now being a little less volatile, would ignite a little later and throw off the timing just enough to slow him down by a few hundredths. This is a guy who had made thousands of passes down a drag strip and documented nearly every one. I'm sure you know how much meticulous record keeping is to a bracket racer. I think he was onto something. Another racer that I know, Aaron Wilson of Team Elves land speed racing fame, builds his engines around the fuel he will be using. We have had several conversations regarding fuel and he agrees. This is a guy who got a Sportster powered Buell to nearly 220 MPH. He's experienced with nitromethane and nitrous as well. I'm not saying that using more octane hurts anything. But if the engine compression and timing is optimized to run 82 octane pump swill, don't you think that using a less volatile fuel would change it's power output some? [/QUOTE]
