No thirteendog, you are spot on. I don't care about going in a straight line over and over again. As for my speed figures, take your rear tire sizes 255 35 19. do the math and you get the height of your side walls in mm and convert to inches, and add to the 19 inch size of the rims. Then multiply by pie to get the circumference of the wheel and divide the number of inches in a mile. When out limiter is removed, the most our engines can safely run at is 6200 rpms. our top gear is .83 and our final drive is 3.27. do the math, without lowering the final drive ratio, the highest speed we can hit is 176. car can be rev limited if your horsepower to aerodynamics is more than enough to push your car past its rpm limit or drag limited if your rev limited speed is higher than your that your cars horsepower can can push its aerodynamics to. I know those figures and facts are correct. with all of TVT's N/A bolt-ons, the N/A can at most put 220 hp to the ground. that gets our aerodynamics into the low to mid 160's at best. I'm still not sure about how all of the aspects with handling work though. And when motortrend compares the viper to playing ping pong with a ball-bat, i wonder if even with an experienced driver if the viper can out handle a German track sports car. Im still unsure bout all that stuff, but I know my top speed facts are correct. I wonder how an XF would handle if I dropped the weight down to 2600 lbs. No airbags, lightweight race seats, steering wheel, insulation, AC, and sound system gone. umm door panels and dash boards gaaaone. lightweight wheels. roof liner gone. Im gongi about this all wrong. Instead of gaining power, I'm gonna loose weight. Also gonna drop some things that make all of this power loss. The A/C sucks power even while off, what else don't we need that takes power?
