so we went to cecil md the last two saturdays and with the -1100 to -1300 DA air i got a 9.89 out of my duster. 2200ft da is around a 10.20 what a fun summer.
if anyone wants to use this air, cecil county still has test and tunes into december.

i met some nice racers last saturday.

440 78 block. 440 source crank indy sr heads 263/265@050 bout 640 at the valve solid cam. mancini gurdle.

I used to love getting those 'new best' time slips in the middle of November. Any pics of your car?

here is a picture if it works.

Nice run, but even in "mineshaft" air, an over 3/10ths gain is a LOT. Your hot weather tune is likely a bit off. Sounds like it may be rich in worse air

Nice run, what were your other increments and speeds and how much does the car weigh at the line ?

i have been leaning it out slowly. it seems to like leaner over richer and it will pick up when i lean it out and the air gets better.soooo i am not too lean.
car is 3120 on the line.

the slip . i do wish the 60 foot was better
