Hi all, I was hoping some of forum the gear heads could give me their takes on the possibility of using a 100-150 shot of NOS on a Gen 4 to overcome the very high DA here. The elevation of the nearest strip is 3900 feet, and after that, it's 4200 feet. Since I'm out in the desert, the temps are typically 80-90 degrees at night. Using various calculators, I get DAs of 6000-7000 feet. In practice, this has equated to times in the 12's, with trap speeds varying from 117 to 119. I read the thread about the car's PCM powering down the car after a shift on NOS, which begs the question: is this happening because the air/fuel characteristics with the NOS is throwing the PCM off, or because of something related to the car making so much more power? If it's the first, then I'm probably screwed, but if it's the second, a 100 shot of NOS would only be taking me up to the car's rated horsepower at sea level (by my estimates I'm losing about 90 horsepower to the low density air.) Does anyone have any thoughts? Thanks.
