Thinking about it, it doesn't surprise me they switched venues to try to break the speed record. As I mentioned earlier, they were trying at the Silver State Classic Challenge but couldn't even beat Option Magazine's Stream Z speed wise. They kept having problems with the computers, according to them. The Silver State Classic Challenge is held in Ely, NV and goes down Hwy 318. You start at nearly a mile high and go down in elevation as you go south towards Las Vegas. It's VERY hard to get cars to cooperate in the thin air at those altitudes. I had alot of problems with both my WRX and my STi trying to get decent power at those elevations. N/A cars just win out. The Stream Z did better 'cause they've been up there multiple times and have finally been learning to tune for the elevation - the SSC crew were newbies.
The MKM events in Elko are at much lower elevations compared to the SSCC events in Ely. ALOT easier to tune for.
