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.

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.

 

about 2800-2900, stock 3.357 VLSD

edit: running stock 235/45R/18 sized tires

 

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)

 

Numbers updated.

OKstateG35 - find out your numbers and post them up please.

 

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

 

2900

stock vlsd 3.357

245/40/19 all around

 

3,000 @ 82mph, 6MT

 

but he wants to know the rpm @ 80mph... so yours is about 2900?

 

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

 

04 g35x all stock except a ztube and pop-charger 3k right on @ 80mph, I have done extreme amounts of long distance highway driving in the G and I always thought that was a bit high btw I have stock rims and 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.

 

2005 G35 Coupe 6MT with 3.5VLSD

80MPH ~ 3000 RPMs

275/35/19 on the rear tires

 

2004.5 6MT sedan

2850 @ 80mph running OEM 215/55/17

I'm assuming I have the 3.3 VLSD
