I know the speed of my car when winding out 4th gear at 6200RPM, which is my basic shift point for all my gears.
That speed is just under 140mph. I would not think of power shifting in to 5th at 140MPH. Now, it is on my bucket list to take my car up to its absolute top speed, which I would guess, but do not know, to be somewhere in the 160's. My 5th gear ratio is .64, my rear is 3.54 and my tire height is just over 26 inches. On paper at least, I could go well over 200MPH before hitting my red line. Of course, we all know that ain't happening in real life on the salt flats. Somebody at ERA told me though that with an anteater nose, my build had a good shot at going past 170. I don't know if that's true or not, and I've never even seen an anteater nose except in pictures.
