22. We had awesome results with the NOS Super Power Shot nitrous system. We tried different nitrous power levels to evaluate their effects on quarter-mile performance. However, we didn't go up to full power (largest jets) because we didn't want to overtax our mechanical fuel pump and hurt the engine. If we were to add an auxiliary electric fuel pump with a fuel-pressure regulator, we could use the full potential of the nitrous system. However, running the middle jet setting (125 horsepower), we reduced our e.t.'s from a 13.18 at 100.3 mph to 12.29 at 109.3 mph through the mufflers! That's a 0.9-second reduction in e.t. with a 9-mph increase in trap speed--not bad for a $350 NOS nitrous kit and a day's worth of install time. The best part is, with the Mickey Thompson slicks hooking and running nitrous off the line, our Chevelle would pull its left front tire off the ground about an inch. After the track tomfoolery, we drove the car home (more than 50 miles away) without a problem and later drove it to a cruise-in.
