Performance loss. Hey guys
96 Z28, Mods in sig
The last 2 times at the dragstrip, the car was unusually slow. The first time around, the air was bad, and humid, and I just chalked it up to that. Yestersay the air was average, and the car is even slower. It goes to 60' OK, but just feels down on power after that, and the numbers show it. It's off .3 seconds to the 330 and .4 to the 1/8 mile, and down a couple MPH. I also had where it did a hick up coming off the line a couple times.
Plugs and wires only have 8,000 miles or so, but the car has been drag raced a lot. They are MSD street fire wires (or something similar to that) and NGK plugs. I have been thinking about changing it all back to AC Delco stuff, and also replacing the ignition coil with a new AC Delco unit just to eliminate that. Cap and Rotor are stock as far as I know, but a PITA to change.
