It's possible with an aggressive flash on race gas and intake/downpipes/exhaust. Trapping in the 135mph range requires a little more like meth and boost in the 25psi range. Would need closer to 750 WHEEL hp to hit those traps.
750 CRANK hp M5 isn't going do much better than the 127-128 range.
It took 800+whp to crack 140+
BTW, here is the latest vid from my build. 60-130 is 5.3s, 100-200kph is 4.6s (VBOX verified)
