Vintage racing is a little less intense as some other forms of racing. The winner gets nothing and we if there is a after car overtaking us we will point them through. Made a friend of Andre Ahrle pointing him through and allowing him to keep pace for a 4th place finish with the 427 Comp Cobra. He asked if I was going to be at COTA in November for the SVRA championship. I said that it was probably not likely unless I found someone with an enclosed trailer to bring the car down and a crew, as there is a high likelihood of snow in upstate NY in November and I have an open trailer.

Morris, I was able to get a friend to get one set of tire temps coming off the track. Temps are listed as the tires sit on the car facing forward.

LF: 100, 101, 109
RF: 105, 96, 93
LR: 122, 123, 124
RR: 105, 109, 107

What do you think?

Jim

LF. RF
100/101/109. 105/96/93

LR. RR
122/123/124. 105/109/107

When you look at these temps.....

1. Tires are not worked hard enough or old tires....temps need to be around 200*degrees

2. RR spring needs to be raised 2 turns or LF needs to be raised 1 turn and RR needs to raise 1 turn

3. Stiffen front sway bar one hole.

4. Pressure needs to come in hot at 30# lbs....on each tire.

5. Probably a right hand turn track.......more rights then lefts....when you run on a right hand turn track....you read LF 1st....then LR then RR then RF....

What was engine temps- water and oil........trans temp ...diff temp.....how much fuel was in car.....

Just some thoughts.......hope it helps....

Morris,

Thanks! Unfortunately with the transverse leaf springs I do not have the ability to adjust the springs individually for each wheel.
the tires are new, so more than likely was not working the wheels hard enough, first time on the track and I was not pushing hard through the corners as I was not sure how the car would respond and if you watch the video, there are some turns at the Glen, especially in the boot where there is very little runoff, about 3 feet of grass before the retaining wall. I will be pushing the limits a little more the next time out.

I am going to have to do something about the radiator, probably have to block off a portion. On the grid it was getting up to 185 degrees, but on the track I noticed that the water temp was running around 140 degrees. Oil temps were at around 180-185 degrees.

I do not have transmission temps or differential temps. I will need to get some of those temperature strips that you were using.
