Before I get any "asleep at the light" or "my gerbil can run 60ft quicker," remarks these were just MPH runs, with no tire heating, no water box, 1/2 tank gas, car exactly as it drives on the street no mods whatsoever, except I was wearing a helmet
Car weight is 4020 with 1/3 tank of gas so probably like umm 4060 with a 1/2 tank (including me). Met a nice TC guy at the track, I'm tired now and his name has wiped off my brain, but I tried to track "Lenny" down but couldn't find him to ask a question to.
I am a little dissapointed but I won't get into that now until I verify if there is a line pressure or transmission/aux trans slip issue.
I will post 2 of three runs. I forgot to try a run with the vac advance disconnected, but I can do that another day.

R/T is usually not pathetic but I find on street nights at NED they don't give you enough time to settle in once both staging lights are on.
So here is the kicker:
I have a TH400, 1:1 3rd, 3.90 rear gears, except the I was bouncing off the 6500rpm rev limiter for the last 1/4-1/5 (I really wish I knew how far for sure, a playback tach would rule at this point) of the track.
So something behind the engine is not working correctly.
OTOH using the 225(flywheelhp/wt)^(1/3) gives me 116.529 which is pretty darn close to 116.61.
OTOH, there is *no* reason why I should be getting near 6500 at the end. I should be doing like 112-113 @ 6000 and 122 @ 6500.
Whadya alll think?
