![]() A few days ago I went for a top speed run, just to see if the heads pulled harder with speed up top. They definitely did. But, when I hit 130mph I was at redline in 4th gear. Now I've heard a lot of people talking about hitting 140+ a lot. To get that fast do you keep it in 4th and hold it in the redline or do you shift to 5th and wait forever. Cause when I shifted to 5th I hardly picked up any speed.

![]() You gotta shift man, because once you're in the red your done, otherwise you might damage the engine, or you'll bump the rev limiter which I I've heard is about 200 rpm's into the red.

![]() What's the top speed with the 3.73's? Do the gears make 5th useful or is still only for overdrive?

![]() The fastest I have ever hade the B***S to drive my car on the road was 140mph but on the dyno running 3.73s out back I got a speed of 172mph @6000rpm.
I stopped after that cause the tires where smoking a little & I didn't think I would have gotten any more from her.
