That surprised the heck out of me, shifting it 300 RPM later out of 1st gear made the car pickup 2.+ MPH in the last 300 feet confused All the other times, 60Ft,330, 660 and 1000 Ft times and 1/8 mile MPH were identical shruggy
I did switch the rear tires later to a set of Goodyear 15x33x15 and that help hook the car up better over the Hoosiers and M/T boogie up work
My new car will have 17x34x16 slicks on it due to having a lot more HP2300+ and in a smaller lighter weight car hopefully making north of 2500 HP luck devil

What was your trap rpm in 1/4 mile? 8 inch or 9 inch converter and what tires were you using?
