I was wondering if someone would come in on the rpm/speed aspects of the picture. This is actually fifth gear but I have put in a shorter final drive when I did the LSD. with a 4.05 final and the .70 fith gear, fith is about half way between 4 and 5 on the stock gearbox. This is not the same as fifth on the newer 9-5 and 9-3 boxes since they went to a taller 5th ratio, .66 with the 4.05 final. I can actually reach the rev limiter in fifth now, this is at 164 mph on GPS. interresting enough I reached 164 mph with the origional gear box at 5800 with some smaller tires about 7 years ago. With my race tires, which are 23 inch diameter Top speed is 157mph at redline in fifth. I havenent been on a track where Ive been able to hit the rev limit in fifth yet. max so far is 145 mph at our local track in Lewistown MT.
