rpms vs speed

[miteclipse93]

hey,
right now i have a 93 tsi awd. when i cruise on the highway i am at 4,000rpms at 75 mph, i live in a country area so its not unlikely for people to cruise at 90. i am worried staying at a high rpm for too long.
i was wondering if the 2nd gen gst and gsxs have a lower rpm range on the highway?

That's fine to sustain higher RPMs for a long ammount of time..... (as long as your not keeping it at like 6k+ for a long time)

I had my car up to 130 for about 50 miles on the highway once.... (well over sustained 5k rpm). You should of seen the look on my face when I passed the cop. (who was asleep)
