Well, was looking for a 9.90 yesterday, but thanks to constant 35mph head winds all day, it didn't happen. This car had been 10.20s @ 133mph last time out with 1.5X 60 foot times, so my plan was just to get the 60 down into the mid 1.4s and click off a 9.9X...... Well, instead up picking up 24-25mph between the 1/8 and the 1/4... it picked up 20....not enough, here are the details:

60...................1.420
330.................4.103
1/8..................6.389
MPH.................109.57
1000................8.390
1/4..................10.111
MPH.................129.62

This was on E85 (74% ethanol yesterday), hitting the scales at 3650#, on MT 255-60-15 Drag Radials, and 28psi with a billet 67 precision turbo. I drove 75 miles to the track, made 3 passes (just turning the 2 step and launch boost up each hit) and ran 10.38@129, 10.24@129, 10.11@129... with 1.50, 1.47, 1.42 60 foots respectively. I made a 4th attempt and uncorked the DP... but blew up my converter when I let off the tbrake (old school precision industries converter that I have been blowing through all year)... I'll be installing a PTC converter over the winter and look forward to driving it to the track in the spring and collecting 9.8X timeslips.
 
Nice work! Can't wait for next year to go back to the e85. Had to run race gas here lately BC I had to go back to small injectors.
