Nice time around the big track

I will be there in a couple weeks.

 

I saw your previous lap time too, you are fast!

I will go again on June 25 and 26 with Speedtrial USA. We have a few Zs going too. One day for Big willows, 1 day for Street. Combo Deal $200. Hope to see u there too

 

Hoping to be a bit quicker this time now that I am more familiar with the car, have a better suspension and an alignment.

Never run with Speedtrial...good group to run with?

 

Yup, very well organize and a lot of experienced/race drivers love to share their experience. I got tons of track time the last weekend. Drove 300 track miles in both days.

Nice lap time there! great job!

 

Thanks. Last time you were there, had the track been re-sealed? When I ran last week, the track had a new sealent. It seemed a bit slicker in turn one to me but overall people seem to report that there is just as much overall grip, if not a touch more, than before being re-sealed.

 

Nope, not being re-sealed yet. I will be there on June 26 again and see the differences. How do u like the RS-3? What tire sizes were u running?

 

I love the RS-3. Great grip, good breakaway characteristics, ok wear for a 140 treadwear tire and they handle the heat pretty well. I was usually running my fastest lap toward the end of the session. I run a 265/35-18 front and 285/35-18 rear.

1.8 second faster than last time at TWS... telemetry shows no loss in top speed with the wing at 0 degrees in center but feeling in turn 1, 5 and 7 is quite different...

Me and some of the fellow TT guys think a low 1:38 is going to win Nationals so I got to pick it up. Just corner balanced the car and took more weight out after this last event so I should be fast in a couple weeks when we go again.

 

What angle do you guys run the GTC wing at for open track events? I just installed mine, so am curious what your experiences have been to help me dial it in to start. Thanks.

 

I don't know the exact angle right now. I have played with it a little at different tracks. I will measure the angle and take some pics of it on the car and the bolt holes I am using so you can get a better idea. I have only ran it at three events so far and I am not 100% the best location, but it feels pretty good. For shorter tracks I adjust it for more AOA. There is a track I run with only one short straight and mostly up and down turning so I adjust it a lot for that one, but Mid Ohio has more straights so it is back out a lot more now. I'll get back to you.

 

Thanks! I think their wind tunnel data suggests that it should be kept at 10* or less AoA, as there are very small gains in DF with big additions in drag over 10. At 15*, the DF actually reduces to the same amount as when it's at 5*. I figure I'll use it at 10 for autox, as there is still some effect, and 2-5 for open tracking, depending on the track configuration.
