New Best on Friday Night!

ok guys, just wanted to update on my progress or nonpregress. I am losing time down the track so I recently installed a 3/8 sending unit/pickup and 3/8 line to the pump then the carb. That gave me about 9lbs of fuel pressure at idle so I then installed a fuel pressure regulator.

Hoping this might solve my problems I went to the 1/8 mile track last night. It didn't. Car ran the same. Excellent 60 ft times but still doesn't seem to live up to its potential on the big end. I think I may try to run less timing next time out. Could it be that this thing is just a beast down low? Really, 7.83 in the 1/8th isn't shabby for my mild budget combo I just keep chasing more because of my awesome 60ft times. Any thoughts are appreciated

Here's a few things that may help.

With 89 octane I run 26* initial, 34* total mechanical, 50* with vacuum. I use manifold vacuum and run 28* at 1000 rpm. 34* total is what is best for me.

You maybe leaning out at the top end. You can go smaller on the Main Air Bleed to richen top end. .002 increment if .028 go to .026 AFR 12.4 works the best for me.

If running Drag radial use as much psi as you can and still hook. Taller tire = more speed at the big end. I run 20 psi MT ET Street 255/60/15

I drive to the track and my car always runs the slowest on the 1st pass. I don't use the #s from the 1st run for data. Uncapping the cutouts improves rev speed.
