I am sure this has been asked before but I could not find it anywhere. What is the REAL top speed of the SC430 if it wasn't computer limited to 156 (or whatever it is)?

 

Well you can actually figure that out by what it would be gear limited to. That is top speed before redline in 5th gear. It is pretty simple math. every cars top speed is determined by its aerodynamics and horsepowe.....capped by redline. Weight has nothing to do with is so long as you have enough road. Im guessing its about 170 though give or take 5 mph.

Check out www.MKIV.com 4th generation supra website, towards the bottom I think they have all formula links and etc.
