The reason I am bringing up the revlimiter issue is that the ACR is known to NOT have a huge top end speed, yet still put down a 7:22 run. Imagine if he didnt run into the limiter in top gear?
I count at least 6 seconds spent bouncing off the limiter on the final straight away. Now think what a 200mph max V instead of a 180mph max V would do for the time
I wonder if all that extra rear downforce is what created what looks like quite a bit of understeer for a Viper.
