Finally some footage of the cars in action. Did you have any heating issues while you were in Vegas? Driving around Vegas without a plate isn't smart if you would have gotten your car impounded you would have missed the race. What car crashed at 200+?

Hey guys I 'll be posting responses from now on answering any questions you have about the episodes. Doug will also be available to post.

ZR1fan- My corvette had some heating issues in Vegas, but they went away when we went to ELY for the racing. Ely is 30 degrees cooler at any point of the the day as compared to Vegas which was 115 degrees during the day. Doug's cooling setup is the same with the exception he doesn't have the AC condenser and he had no problems. I just cant pull the A/C though need it to drive the car on trips. I dont know how other Supercharged cars will perform in the heat but I am sure there is a design that allows for the A/C to stay and the car to stay cool.

fkumro- The cars, we were assuming were about the same HP on the trip. Thats why I was surprised when Doug pulled past me. Both cars were running terribly rich though, Doug forgot to factor in the elevation change from sea level in NY to 8200 ft in ELY. That results in a loss of boost of about 4 lbs and the computer is still adding fuel for 15 lbs. Doug has a wideband 02 in his car so he was able to turn his alcohol injection down to lean out the car. Where if I did that I wouldn't know if I were leaning it out too much. We haven't raced them since through because Doug forgot to turn the alcohol back on when the car came back to NY leaned out and blew his motor the first day back.

Hi guys,
The main reason why my car pulled harder up top was because Robs car was running richer than mine, much richer. It was a lesson learned that we needed to take the elevation more into account, it made a huge difference on the cars!
Since this trip we installed a wide band O2 in Rob's car to prevent this from happening again, but for the trip I could not take my tuning software because I could not leave the shop without it for so long. That's another thing we changed by purchasing a second complete master version of our software so I can bring it to the track or events like this. That is not a cheap investment, but worth it in the long run since I can do "on track" tuning at the road courses now which is always going to be better since it's next to impossible to sustain the upper rpm's in the street like you can on the road course.

Temps from the desert heat were always on my mind, my car averaged 220-230 the whole race, but for holding the rpm's we did for the time we did, that's not too bad.

To clarify Rob, I have A.C. also, there is no way I would ever remove that on a street car! Race car, different story.
