What RPM are you guys at when cruising at 80 mph? I'm trying to see what the actual #'s are for people depending on FD gears.

I have a early 2003 sedan. 3.3 FD open diff. I'm right at 2875 rpms when at 80 MPH. I am 5AT.

Tollboothwilley 2875 5AT
Candlestick ~2900 5AT
Radioguy21 ~2900
OCG35 ~3000 5AT
Blue Dream ~2900
Ttrank ~2600 6MT
TwiilightBlue 2850
Antipd32v 3000 5AT X
ntrinsik 2900 5AT



3.5 FD
CandlestickPark ~3200 5AT
citymunky 3000 6MT
thescreensavers 3050
AaronHL ~2900 6MT
OKStateG35 ~3200 5AT X

I think my X has 3.5 gears stock, but I'm not 100% sure on that. Anyway, my RPM's are just over 3K at 80MPH. I'll get a closer estimate next time I'm on the highway.

Recently upgraded to a 3.5 FD w/vLSD (love it!). Will probably eventually go with 3.7 gears.

3.3 FD ~ 2900
3.5 FD ~ 3200

for my car:

3.3 at 80mph = 3K rpm (with 235/50/17 - iirc)

3.7 at 80mph = 3250 rpm (with 245/40/19)

if you want specific relevant data, you should request/require tire size... since they will alter speed if not exact diameter as OEM.

Yes, that should be correct. I only specifically remember the speed at 3k on the dot. Stock tire size.

I'll have to check. I'm 6MT with 3.3. I think it's in the 2600 range but will check on the way home if traffic is light.

I'm also going to move this over to the drivetrain section.
