Ok, the first time I went to Silver State in my old '84 Vette, I was doing 208mph with no spoilers. I had the car really low, street Michelins (didn't know any better), and I had a passenger. The car handled fine. I had the Konis turned to the max stiffness and a good alignment done. The next year I went back with a stronger motor and had to have a cowl hood to clear the bigger carb. Same suspension set up, different passenger and the car was all very unstable above 185. Infact, I could only go about 195 because it was really scary. I couldn't believe that just adding the cowl hood made that much change in the aerodynamics of the car. Up to 170, I could basically drive one handed and have a conversation with my co-driver, above 175 it was another story.
As far as 1/4 mile time, my old 6spd Supra ran 9.81@ 153.7, so you can run over 150 and still be in the nines if your car has alot of power and is not set up for the 1/4.
I did the Texas mile in my Viper 2 years ago and ran 191 with it making 650 rwh and 657twt. I'm going back later this year with the Viper, now that it's making 1300 rwh we want to see what it will do. The problem now is how we are going to hook up 1300rwh on street tires. We are going to have to turn the boost down and probably have to ramp it up with the ECU through the gears. I hope to crest the 200mph mark in the standing mile.
Bottom line is, it's not all just about horspower, there alot of factors for you to get that horsepower to the ground and being safe at the same time..
