Achem...yes you guys are missing something.
Between the 108 mph 3rd gear limit at around 4000 rpm, and the 128 mph limited top speed in 4th gear, the engine will accelerate slower than if the transmission were allowed to stay in 3rd gear until 5500 rpm like the 1st to second shift at 5500 rpm.
Once I was doing about 110 mph cruising in 4th, I matted it to pass another car, it downshifted into 3rd gear and the limiter came on so it slowed to 108. I had to lift the throttle so the trani would stay in 4th gear to get it to over 125 mph.
Yes there are a few stretches of unpoliced deserted highway around here where those speeds are normal.
....and speaking of using the gear selector....Don't you ever down shift to use the engine as a mild brake during high speed manuevers?
I find it difficult to maintain 115 mph in hilly terrain through mountain valleys without using 3rd gear. Puts you closer to the peak power rpm.
Anyone who owns a 2000 SSEi and doesn't understand what I'm talking about has never driven it faster than 108 mph
........in 3rd gear with a stock PCM that is.
