That was according to the current owner, Bobby Bitterman in AL. The car now races vintage, but is still in IT trim, tires, and the Sunbelt IT motor that was sold with the car. Not sure what if anything might have been out of IT spec other than the RR shocks. I could be wrong, but I'm pretty sure he told me he turned laps in the 1:17's. It was captured by the data acquisition system on board so perhaps there's proof.
No doubt in my mind that car would be faster than John Williams. 1:17's? I dunno.

Keith and Ron,
I know Keith said same tires but slicks are allowed in vintage. He probably ran slicks. Which would help close the gap between ITS and EP times. That would be close to the same setup in Grayson's old car I think. Then 1:17's would be real doable. Don Ahrens ran a 1:17 last year in EP at Roebling in a 240z.

Hey, how come my quote stuff didn't work?
Actually it was a 118 and small change. The car was on dot's and the only thing not ITS legal is the rr shocks. Great weather and good drafting partners a (gto and a 914-6). Three laps were in the 118s. There is alot of set up difference between Johns car and mine. Most of the lap time came from turn one and two. Enough corner speed that I stayed in 4th gear from the front straight untill turn 4. I have learned that Z cars are very alignment sensitive.

Ok Bobby, you know someone was going to ask! What did you do alignment wise to get through 1 and 2 so well??? Z car guys want to know!

The easiest way to put it is that Keith took full advantage of the rules when it came to strut housings. I am lucky enough to have two sets (one set for each car). Most, if not all Z cars have bent strut housings to get the proper camber. Having had a set of those in the past and compairing them to what I now have thats not the way. My experience has been that Z cars want all the camber that you can get and then some. 3-4 degrees isnt enough, closer to 5 will get you in the ball park. The only difference in the car from when purchased is the alingment and the driver. I am nowhere near the driver Chet is, I would bet his time would be even faster. I can say that that alingment does not work as good for RA though. It works at Barbers and Roebling.

Jeff/Ron......This series one 240z "Keith is refering to" ....Blue/Blue car wasn't super fast...in a straight line, but handled quite well..I was privileged to be a passenger in with Chet driving that weekend back in 1999/2000 maybe.... I remember well cause Chet done blowed my engine up that weekend telling me to go faster :eek:.......Damn V-8...
Many moons ago......
Ready to try some extreme camber at the SIC........Hmmm...
