East Tennessee Region SCCA

I got 82-84 coming up the middle section on my last run with aerial in the car. It was the only time I hit the limiter.

Interesting. Cathers maxed out at 73 there and I was at 69.

My engine data which is all I had Sun had me at 6349 rpm and 84mph.. last 3 runs.

could your tire size have altered that?

Admittedly I only had two runs, but even if I'd topped out, which I did not, I would have been at 78. I was probably 75ish through the middle and I doubt very seriously if any cars were faster.

sounds like your a tad low on torque...

Hmm, I need to see if SoloStorm was reading speed from the GPS or the car's speedo sensor via OBD. Top speed at redline in 2nd with the 335 BFGs is 89 and I don't recall being anywhere near the limiter. The 18" BFGs are about 3/4" shorter than the factory size, so I'd be travelling about 2 mph slower (actual) at 70 mph than indicated by the speedo sensor, assuming its even that accurate.

I don't feel like we were anywhere near 80+.

Sat. my engine data and Solo Storm was 1 mph different. 69 and 70 going the other direction. It felt faster Sunday to me for sure

Well that explains some of why I was slow. My top speed was 64. As I remember, I was a little out of shape going into the showcase turn on that run and at one point was pointed right at the workers.

I wonder how accurate speedo data from the car is though, dont speedometers typically read high to prevent people from speeding as much? Any idea how much power that challenger is making at the wheels JB? JY's mustang is at 550whp/3700lbs, the Z06 is probably 440whp/3200lbs

Speedos are up to 10% fast..ZERO% slow by law.

Im prolly close to 530-550 wrhp now. 3750ish lbs.. Id say JY is lighter than 3700 tho.

I thought i remember him saying it was something like 3400-3200lbs and 522rwhp

Yeah, the Z06 should be a little north of 500.

C6Z's normally put down around 440-450whp stock IIRC, 505bhp. Dont really know the bhp for the mustang or challenger to compare since theyre so modified. Your car is skinny and light Harp! whered he lose all that weight in the mustang?! It was 3700 a couple years ago I think.
