i think mines aroudn 4500 +/- 500 @ 80mph as well

98 ls manual

 

yessss somebody's 1st post doesn't suck.

Mine's at 4k at 80mph, but we drive completely different cars. Eh.

 

sounds normal.

 

That's not normal, it's not shifting into overdrive (4th gear). Check to make sure you're in D4, and if so, then there is a problem causing the transmission not to upshift all the way.

 

Yea, espically in an auto LS, that's not normal. Even in my gsr, 80mph in 5th gear is around 4100rpm.

 

at eighty im at like 3800...i'm not doing 45k's until im at 100mph

 

Im using the gear ratio calulator from T-I

It says the following for a 1990-93 acua integra auto

80mph in 4th gear ~3750rpm
80mph in 3rd gear =5000rpm

So I dont think the problem is that you are in third gear. Maybe your speedo or your tach is off? Just my opinion Im not a transmission specialist.....

HTH

EDIT to answer your question the RPM at 60MPH is

5700rpm in 2nd
3750rpm in 3rd
2750rpm in 4th

These are not exact but they should be close.....+/- 250rpm

 

yes, the speedo cable may be a problem! i forget to tell this!
when i am on Interstate 95 at Maryland, i received a warning ticket from cop who said i was over 8 mph at 65 zone.....but i have crusie at 65+/-2mph! Damn at cop, wasted my time!

than ok...i tested today with another car on freeway, i followed him. when he was driving 65mph, my speedo is 55mph.....OMG

What is the problem of this occur? Thanks

 

what size tires are you running? a larger tire circumference than stock will make the speedometer read slower than you're actually travelling.

That's would be my guess as well.

unless the speedo was adjusted when the different tires were put on then that wouldn't affect apparent speed vs the RPMs. Would still be the same.

yes, but read his other question. his post before mine asked why his speedo showed 55 when he was going 65.

 

Sounds about right, depends though, what gear are you into around 60mph?

Affirmative

 

i have a G2 ls auto too.. i got some questions bout this also..

lets say you drive at 65mph rpms for me are at between 2900-3200 rpms.. (not sure if thats normal, you tell me) do you use more gas by being at higher RPMs? and is it bad for your engine to be running at those high of rpms for a period of time?
