Well had the 55 back up on jack stands the week after the Fall Classic and installed one of Larry Hill's 8 inch convertors he was so very kind to loan me. I was pleasantly surprised on the first run as the car picked up over a tenth in the 60, and 2 tenth in the 1/4 over the Indy runs the week before as it ran a 13.44 at 98 mph on the 13.80 index.. Some of this had to be related to the better weather conditions and a nice little 10mph hour tail wind but as the playback tach showed it was the first convertor out of 5 units tried that flashed upwards of 5000 on the launch. After 4 runs or so trying a few different things with no gain I decided to take out the 200 lbs of ballast I carry to make the Q/SA weight to try to hit the magic 100 mph barrier. Got close in the next few runs with a runs of 13.22 at 99.57 mph but no cigar. LOL Earlier in the week I had a nice conversation with Charlie at ATI and he said he would attempt to loosen up my convertor so it has been sent back to them. One of the local tracks has some test and tunes listed in the first few weeks of November so i will try to make one of those to close out the season. I feel that if I can get the flash stall up to around 5400 it will help the car.
