dyno numbers

[whitesnake94]

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?

Mid 13's at the track shouldnt be too hard to get for you at the track.

Those are nice numbers, I can't believe how low your torque was on the first pull.

yea I couldnt believe that the sensor was leaning the car out so bad. I think maybe a 13.7 somewhere around there. I kept doing bolt ons and didnt see any results the whole time it was the mass air sensor. Is that about right for my bolt ons?

Check sig for my numbers

if you can drive your car should run mid 13's at about 101-102 mph. Don't think that it'll runt that the first time though. It could take like 30 runs...No joke...just practice. Oh yeah and..... Don't take your foot off the gas...
