Default 2018 Silver State Classic Challenge

Bill and I just got back from the 2018 Silver State Classic Challenge Open Road Race. The car had some electrical and over heating issues in May so I missed the 2018 Nevada Open Road Challenge (NORC). We addressed a few things and dynoed the car before Bill moved to Arizona. Since I wasn't sure how well the car would hold up, I signed up for the 170 class instead of the 180 class that I ran last September.


Parked in Ely, Nv next to the motel.

We had a hard to start problem when I unloaded the car from the trailer, but after cleaning the contacts on the starter and hitting it a few times with a hammer, the car eventually started, though I think it was more of a fuel map issue since it acted like the car was flooding, and continual use of the starter drained the battery. After the initial incident, the problem didn't return. We did make a few 3rd gear uphill runs to tune the fuel and ignition maps for the higher altitude.


In the finish pits.

I started the race like I would if I was running the 170 class, but with an easy start and closely monitoring the temps. After a few miles I upped the cruising speed from 185 mph to 190, then up to 195. I didn't want to try for 200 mph until I got to the Speed Trap, just in case there was still overheating issues. When I got to the Speed Trap straight I slowly increased the speed up to and past 200 mph. I got to 207 mph when I passed the trap. Since there didn't seem to be any problems with the car, I decided to go ahead and run the rest of the race like I was in the 180 class. Since I was the only car running 170 this time, I just needed to finish to win... The car continued to run well, and I hit an 180 mph average before checkpoint 6 (60 miles in). I decided I'd better slow down a little so as not to pass the 10 mph avg over target speed limit at the official restart point and risk being disqualified. After that I continued on at a 179 mph average until I got to the Narrows, a 3 mile twisty section, where the average dropped down to 175 mph. After that I just maintained that average until the final straight, 5 miles long to the finish line where I decided to see how much the car had left. About half way through the straight I was at 200 mph, 19 seconds later I as at 210, then up to 213 mph 10 seconds later. Then I dropped back down to 211 as I crossed the finish line.


Screenshot from the Garmin dashcam/gps video showing the speed at the bottom of the image.

All in all it was a very good run, 176.1729 mph average, 213 mph top speed (though only 207 in the trap section), a 1st place trophy. This was the 30th event for this car (120-180 classes) and 3rd 1st place in 170, and 3rd 175+ avg mph run.

Thanks to Bill for all the help and to Todd (Erik and Tim also) for his help in May to get the supercharger checked out.

I read the last paragraph to my wife and she was horrified. Especially at this: 213 mph

'All in all it was a very good run' Hard to argue there! But where's the video?

This time I managed to get some video from the whole race. With the idea that more is better, I had six video cameras mounted on the car, and five of them got something. But since I'm on the way to my stepson's wedding tomorrow, it'll be a few days before I can get anything published. The same is true about the photo gallery. Heck, I haven't finished doing the video from daughter's wedding last month....

You make it sound so easy. Just got in the car. Watched the temp gauge a little more closely. Went 213, and 207 through the traps. Didn't want to break out by more than +10 and risk a DQ. Didja have a drink in the cup holder?

There's a year of preparation before every year's events. It takes a huge amount of hard work to make it sound so easy. Congrats on the results and the work it takes to get there!

Thanks Bob,

Yes, lot's of work and preparation, so I'm very glad it work out well.

And between packing I did a small video of the ride to the front of the grid. They let the Unlimited and Super Sport cars go first this time, so we got to see all the other cars at the starting line. This is taken with a cheap 4K dashcam with gps, the time is set to the China time zone, and the text spacing at the bottom is not very readable.

Hi George,

Amazing run, congratulations!

Can't imagine holding those speeds for such a long run on regular roads, you definitely have to have confidence in your car and driving skills.

Enjoy your stepson's wedding!

213 mph!

Congratulations, that was an exhilarating read...

What did the car dyno at?
Stock or GT cams?
What was your air/fuel during the run?
What spring rates/shocks do you run?
What is your alignment setup?
What tires and their pressure?
What was your engine oil/water temps?
Tranny temps?

Your car performed like a Swiss watch, and its performance shows it is setup like one where all the parts worked together perfectly.

That takes a lot of hard work behind the scenes to pull that off and make it look easy on race day.

Awesome. True testament to the car and Tim's SC set up...and not to mention your nerves of steel and the the size of your ....


an idea If it helps.... i wired a inline switch so i can depower my fuel pump. My car occasionally has trouble with rich starts. Turn the pump off, crank ...pressure drops....at the correct mixture as it clears, it fires right up after a couple of turns....then i simply turn the pump back on. i dont even leave the seat.


Congrats again on all your ORR stuff.

As i look at that video,. is the 928 the "oldest" car in the field?

Thanks, To answer all the questions will take more time then I have right now., I see if I can answer a few later. I'm on the way to the airport in an hour.
