What should my rpms be at 70 mph?

redips · 01-02-2008, 01:37 AM

Hello, newb here with 90 na 7mge automatic and was just wondering what my tach should read @ 70 mph? It currently reads 3k and that seems a little high to me. Also the car shifts hard from 1st to second when cold then seems to get better when the car warms up. Anyone have any ideas?

if you have the same automatic tranny the turbo has...which i think you do (why dont i know that? im stupid. whatever) 65 mph is 2500 rpm on my A340E...3k should be closer to 80 than 70, but its close enough i guess.

well, i know for a fact the turbo and na motors have the same 4sp automatic. don't ask me about speed verses RPM but to me 3k rpm at 70mph sounds about right.

Hey guys thanks for the response. Seems like at 3k the engine is working hard at cruising speeds. This is my first supra and just want it to see if this was normal. Thanks again.

~3k for 80mph on a 5speed Turbo.
still, at 3k(

80mph ), my motor sounds are more pronounced than at 2500 rpm. "kinda" hums harder.
Also many cars I've driven change tone at 3k. not just the supra. (rx7, 300zx, etc)
Still, I like the sound of my modified 7mgte, Vband t4, & 3" exh pipes prolonged at 5k in 5th GEAR
