Geezer, good luck tonite!Doug what air pressure are you runnin in the tires?
Rich,
28 lbs, anything less doesnt seem to help any.
Last night sucked!! Car slowed down instead of speeding up! :x :x
Ran a whole bunch of 15.5x's @ 87 mph.
If you think my other 60' times are bad look at this one!
Never hooked posi's at all and I blew away the right rear out past the 60' line....said piss on it and just kept it hammered....
2.8999 60'
10.665 1/8 mile @ 70.62 mph
16.2629 1/4 mile @ 87.02 mph
2 problems IMO....
I switched from a 5.0 power valve to a 6.5 power valve a couple of weeks ago. I now believe that the power valve is opening and closing at idle because of my low vacuum. This coincides with the info my Holley book is giving me. So I switched back this morning to the 5.0 power valve.
It was loading up, and the plugs are lean looking but dripping wet with fuel. Carb has power valve protection and it did NOT BACK FIRE at the track.
When I was switching power valves I must have bumped my float becuase when I checked the float level I had to raise it almost 1.5 turns for it to start dripping out the hole in the side of the bowl.
Swithched everything back the way it was last time I went to the track. Going back next friday night and try it again. I could tell it was laying down the whole way...just didnt feel right.
Best pass was a 15.51 @ 86.51 60 ft 2.27 1/8 mile 9.91 @ 71.22 mph.
I did reset my timing from 40 degree total to 36 degrees total. Didnt seem to make a differance et wise but it does seem to idle better now.
Air temp was in the 80's to start and cooled of into the lower 60's and it didnt go any faster at all like it did last time.
Also,
It didnt matter wether the carb was ealed to the hood with the K&N filter or not. Pulled the filter, ran it sealed no differance. Ran with just the K&N filter in the regular aircleaner. No differance. Ran just the carb baseplate without it being sealed to the hood. No differance no matter what air cleaner setup I ran.
This is what leads me to believe it was a fuel problem.
Later,
Doug
