We had first test and tune of the season on Sunday. Wind was a headwind 25 mph and gusting to 40, so wasn't a great day but temps were great in the 60's.
The first pass was n/a to 1. Break in the new drag radials and 2. Get a good baseline on the new Viking shocks/settings.
It hooked did a small wheelie and ran an 11.50 and did what it was supposed to (it runs a little slower with the colder plugs, heavier weight oil and the nitrous plate impeding flow.) Usually runs high 11.30's to mid 11.40's depending on weather, so I was pleased with the first pass.
I turned on the bottle, made sure it was ~95°, and made a pass. The nose came up and then fell pretty quickly, causing it to buck and do a 1.50 60. (Should be high 1.30's).I adjusted the compression a couple of clicks and ran almost identical passes. 10.30/10.32 @ 130 mph. I had removed 50 lbs. out of the trunk and really should have left it so I wasn't making two changes at the same time.
So overall, not a bad day considering conditions and learning new stuff.
Nerd data points: It used 5.4 lbs. of nitrous and half a quart of supplemental fuel for 2 passes @ 250 shot setting.
Shock settings:
12 Compression and 4 Rebound for the n/a and first (10.30) nitrous pass.
10 compression and 4 rebound for the second (10.32) nitrous pass.
Whats the flowing fuel psi? do you have a flow tool?
Should be 5psi and no, I don't have a flow tool.
'63 Dodge 330 11.19 @ 121 mph Pump gas, n/a, through the mufflers on street tires with 3.54's. 3,600 lbs. 10.01 @ 133mph with a 250 shot of nitrous an a splash of race gas. 1.36 60 ft. 3,700 lbs.
