I have a 94 cobra with the following mods(140,000 miles on the engine).
355 gears
msd 6a box
mac underdrive pullies
c&l 76mm mass air and pipe
paxton fuel pressure regulator
mac long tubes and off road H-pipe
2 chamber flowmasters w/dumps
the first pull it put down: 242.7hp and 267.2torque
The car was very lean
It was at walker dyno tune in Trussville Al. he said first we should clean the mass air sensor. He had sprayed the sensor with some carb cleaner. Nothing else was touched
second pull: 259.2hp and 297.6torque
I was freaked out on the second pull I could not believe the dirty mass air sensor was leaning the car out so bad.
Pretty much we lost hp the rest of the time trying to tune the car timing and fuel pressure etc.
the last pull the curve looked a lot better: 256.6hp and 294.5torque
the car feels so much better.
My best time on the 1/4 mile was 14.0. What do you guys think I will run the next time at the track?
