I went up 3 jet sizes initially due to atmospheric conditions and after some chassis tuning ran the [email protected] 1.57 60ft Atco is 33ft above sea level. I forgot and left my spare tire in the trunk or it would have been an 11.0. I went to Island Dragway on Sunday. Ran 3 times did a tire pressure adjustment and took the spare out. Similar weather conditions but Island is 513ft above sea level. Got 2 half passes with 1.55 60ft times. Last run went all out and got sent to tech for the lack of a roll bar which I knew. Ran a [email protected] with a 1.54 60ft. I need to get it on a chassis dyno or get an LM2 and get a bar in it before I go any further. I have a hunch there is at least another 10th or two hiding in tuning.
