Katie bar the door! A new best using E85 and the Ron's Flying Toilet Injection in my Dart. http://killerrons.comI almost didn't go to the test and tune today. The overnight low temp was low 30's and I worried the ground/track would be too cold to hook. The forecast high was only 49F, and the test session ran from 10am to 6pm. But you don't get the timeslip sitting at home, you have to be there! The sun did shine all day and the black top absorbed enough heat for my backhalf, ladder bar car to put the power to the pavement. Maryland International Raceway (MIR), http://www.mirdrag.com , is only at 80 ft elevation. So, the high pressure and dry air mass together with the cool temps produced mineshaft density air conditions to make loads of power, and the Dart hooked it up! Attached is the timeslip. The air data was 51ºF, 31% RH, 30.28"Hg  That is about minus 800-850 ft density altitude (DA).  The first pass it went 9.216. So I richened the mixture for the air conditions. It went 9.210 pushing hard on the wheelie bars. So I put more fuel to the fire and aced the starting line on the 5th pass 9.158 at 143.2 mph!  I just adjusted my sig from the old "mineshaft air" best of 1.23, 5.79 @ 116, 9.21 @ 142

Nice! Gotta love this early spring air.... Pretty high pressure this weekend over East Coast.... I saw 1026 MB/~30.3" on the Baro this AM before we left...
Took my Buddies 436" SB Challenger to Beaver Springs for T&T this AM, got there little late @ 10:45 AM, I registered -1065 feet DA on the Performaire...... That was lowest I've ever seen on it @ BSD. Off top of my head was ~37 degrees & 30% humidity.
Only got 1 pass due to a badly leaking slick, & car spun, so no new best.... air was about -700 ft around 11:45 AM when he got his one & only pass. Know we could have easy bested his previous best 9.87 which was around +600 DA last fall. Should have been in the 70's today. Just perfect weather.... sun on track, ice cold, low humidity air.

Yes Bob, New bests all around. Sixty foot, 1/8, mph, 1/4 everything. I think I am pushing this chassis to its limits. But summer air will bring me back to earth. However, the E85 doesn't slow down as much as gas in the hot weather. It is between gasoline and race alky (methanol). If it would have gone 9.10, I would have rejetted for methanol and filled the tank for the shot at the 8.999 timeslip.

Unbelievable Jim. 
1.22 60 foot.
X 2, That sixty is killer 
Big Jim,
I don't know everything that was going on, but on the 4th pass there was a screw-up and I ended up deep staging. It was a test and tune so I just went for it. The RT was a big red light (no kidding) of -0.134. But what surprised me was the sixty foot of 1.299; and that 0.06 difference from pass 4 (9.18) held to the end of the 1/4 mile. Much bigger difference than I expected for deep staging. Could have been other crap that run (big starting line F-up/delay), but the incremental times (60-330, 330-1/8, 1/8-1000, 1000-1/4) were all normal.
I could have made more passes today. But after the 9.18 and 9.15 timeslips, I was happy to go home with no broken parts and get some dinner and a beer.
New Best: 1.228, 5.76/117, 9.158/143
