I had a few friends who knew of an open road with no other cars... so we did some super scientific tests. Cars were a tuned Nissan GTR, Roush Stage 3 Mustang, & a supercharged Ford Mustang GT to see how they held up against my 997.1 Porsche 911 Turbo with Cobb Stage 2 and Tubi Exhaust.
Some sort of pro charged Camaro 1LE was there in the beginning too, but that car is 700-800 HP, so in a different league than the others, so I didn’t put that in the title.
I would have killed him from a dig tho— just saying. ;-)
Theoretical speeds were 60-120,130 (just happened to be the speed limit where we were).
*disclaimer: racing on public roads can be dangerous- even if you have cars built for those speeds. Please don’t try this at home, and especially not if there are other cars are on the road where you could hurt the people in them.
