i think mine is somewhere around 3.3k
i know when im at 80mph its at 4k

 

Good to know, thanks. Just felt like it was a bit high.

Does anyone with an A/T want to chime in on what RPMs you're at around 60mph? I'm curious.

 

2010 and 2011 base models have better highway gearing (3k at 75mph).

 

If I remember correctly, Tire Size on 2009 Hyundai Accent is:
- Default: P185/65R14 85H
- Alternate: P195/55R15 84V

If there's clearance room within its fenders, perhaps upgrading to P195/55R15 or P195/60R15 is better than current size???? To verify different engine RPMs and speedo reading changes, plug current size and larger size numbers into Tire size calculator

Note: When making rim &/or rubber size changes, remember to stay under 3% change. Thus, ensuring its speedo, ABS and ESC remain happy. If wondering, I changed rubber size on my previous vehicle and it did help. Wasn't a perfect solution but it did help better optimize its inefficient engine RPM to gear ratio final performance.

Hope this helps... Especially if you need to replace current rubber anyway...

 

What in the heck are you talking about?? Are you saying that putting larger diameter tires on will help lower rpms at highway speeds?? Cause if so you need to some research :blink:

 

2.5k at 60

 

Yup , same here with my 2006 auto .

 

yep pretty much the 2006-2009 5 spds are geared at approx.:

3000k rpm at 60mph
3500k rpm at 70mph
4000k rpm at 80mph, etc.

** the autos are geared for lower rpm's at higher speeds.

 

2.8k at 70

3k at 80

4.2k at 100

 

what are you talking about, you cant do 100 mph
maybe 100 kilo lol

 

my car can get to the 100... lol it takes a while but he gets there

 

You'd be surprised, these little cars are actually pretty comfortable at 100mph... Anything faster is incredibly scary and I wouldn't recommend it.

 

haha i know i was just giving kriz a hard time. i been to 96 before, but ever since i got my rims my steering wheel vibrates like a mofo pass 65. so i just stick to 60 mph now lol

 

Fastest I've gone is 96 in the company owned impala. Had to rush to pick up some equipment. It was an impala, so the ride quality didn't change even at 96mph. It was garbage no matter what speed you went.

Dang I freakin' hate impalas.

 

Did some checking against my ScanGauge tonight (since neither my tach nor the speedometer read correct.)

'06/automatic

50 MPH - 1992 RPM
55 MPH - 2263 RPM
60 MPH - 2440 RPM
65 MPH - 2680 RPM
70 MPH - 2875 RPM

 

Everybody who has been in my car comments at how high the rpms are in relation to speed. Just got back from west texas where we have 80mph limits, at 85mph its like 4.3k rpms. The nice thing about it is that going up mountains it has no problem at all maintaining that speed with the ac on. With my cc set, I was passing many larger v6 cars up the inclines, until going down them, as they had their cc set for a higher speed than I did. Later, I passed them again while they were stopped by the hwy patrol, lol.

 

i did and it cut the vibrations from being sporadic after 60 mph, to now it vibrates at 65+ consistently lol

 

wheel balance, or some sort of issue with alignment or suspension.

I have no hubcentric rings, the wheels are centered by the lugs only, at least once a week I am crusing at 80mph or above on the highway, no vibrations at all.

 

mine would vibrate going past 85 but why would i need to go that fast so no worries

 

Yeah mine start at like 65 and then kinda stop at 80 lol

my car can get to the 100... lol it takes a while but he gets there

LIES! hahaha

See i had no hubcentric rings and it was way worse. My tires are balanced, and i had an alignment before the drop and wheels, maybe i should align it again?

Idk im just thinking about selling the rims anyways

 

You should get an alignment, but it won't help with your vibration. It's most likely the tires or rims, as you can balance almost any tire and rim, but that doesn't make em perfectly round. I always choose a high end wheel and tire, they tend to be made to stricter specifications. I have no vibration in my car at any speed, and yes my car easily exceeds 100 MPH.

 

See!!! mine doesnt get easy to 100 tho xD

 

One thing I have thought about is when its time for my car to get a new clutch, is if I may want to swap the gearbox out. The Accent blue has better gearing for more mpgs. I would think the gearbox from the blue would fit in my gls. Or could the trans be rebuilt with the taller gear for 5'th?

 

you could probably get it rebuilt...but $$$$

 

I do 3000 rpm at 100 k/h.......
