I've kept it at 144 mph for about 10 seconds on a flat straight road, wasn't climbing at all.

math will tell you its impossible for our cars to hit 180 mph in stock form. It requires a little more than 300 hp to get to 180 mph...that's 300 hp at the wheel. Our cars are only 306 hp at the crank.

My guess would be it tops out around 160 if we are lucky

Default 06 350

[QUOTE=Kingdavid;7049078]So our limiter is around 150-155. I've hit that with a good couple thousand RPMS left in fifth gear and the whole of sixth gear to go.

I know that past that speed, aerodynamkics start to play a serious roll but with all that grunt left in the engine (she was definitely trying to nudge past the limiter) and a whole gear left to go. What is the actual top speed of the 350?

What do you guys think? I'm guessing we could grab 180 and maybe scratch for 190. 200 mph is a lot harder to achieve than most people think but who knows, maybe the 350 is a 200mph machine.[/QUOT
