EnderSS

That is what my car is doing also.
I just thought it was running a little high for 5th gear

OEM tires are 225-40-18. Different brand tires can have slightly different dimensions. Mine runs about 2900 rpm at 80 mph.

225 40 18

The pic above is a SS/SC with a 4.05 final in it compared to our 3.82 final . You should be around 2850 rpm at 80 according to this calculator ....http://www.f-body.org/gears/

tire size shouldn't matter, unless you re did the computer, it doesn't know tire size, it just knows how fast your wheel is spinning, by telling it tire size that is how it calculates MPH, so if it thinks your stock, it will calculate the wrong speed if you have a bigger or smaller tire

5106 in 3rd...haha just looked at a log... 2950 in 5th

Thats via HP tunes by the way so its fairly accurate

Thats not too high considering my friend use to have a prelude that was somewhere in the 4k range in 5th going 80 lol

08 SS/TC

5th gear, 80mph.... just over 3K rpm. Maybe like 3100-3200rpm.

EnderSS

Thanks
It looks like everyone is close to me. I am just a little over 3000.

Hell, my 1990 Prelude was just about redlined going 80 and it would start going all over the lane. My 93 Civic topped out at 82 and I could only get there if I was driving down a hill with a breeze behind me.

lol I have a Dodge Dakota That is the same way
