Leo uses 105 octane, Lighter wheels and tires, also has 160° thermostat which is programmed into his custom tune, lowered spring, launches full throttle preload and then slips his foot off the brake. All that adds to 4 tenths. I was a Atco Saturday when he did it.
April fools, he uses Nitro and his Edge has a Acid dipped body, no passenger seat or backseat, no rugs, the car is stripped out, on a custom rear drive chassis, with 17x36 16 slicks.
