What's your MPH at 2K RPMs?

TITANTX · 03-12-2004, 03:48 PM

With the lower gear ratio in the offroad and tow package I am hitting about 68-69 mph at 2k rpm. Just curious as to the difference of those without offroad and tow package.

At 1900 I am running 80 which is the required minimum California speed limit.

67 mph at 2000 rpm...so no wonder i my mpg milage is so low as i cruise around between 75 to 90 mph

70mph looks like 1750-1800 rpms.. ref. my signature.

Running a 2wd KC/SE. No off road or big tow. At 2K rpm in fifth gear - going about 78-79mph. At 2k rpm in fourth gear - looks like 65-66mph.

79-80 mph at 2K rpm in a 4x2, no off-road, no big-tow

Last night I went to move a video game and a pool table on my 14ft trailer, and with the empty trailer I think I was doing about 70 @ 2K on the way up with two other people in the truck. The truck is a SE CC 4 x 4 with the 26570R18 wheels and tires.
I will check again with out the trailer.

With out trailer, or anyother passengers, I am @ 80mph +/-

How good does that Subaru run?

MZ3Cosmo · 03-13-2004, 06:30 PM

79 - 80 Mph @ 2k for me. This is in overdrive ie 5th gear.

*tortuga* · 03-14-2004, 03:34 AM

just like everyone else, 79-81mph @ 2k rpm.

Titanic Tiff · 03-14-2004, 07:37 AM

Yesterday I checked this out and I was running about 78-80mph at 2k rpms.

TITANTX · 03-14-2004, 07:56 AM

OK so it looks like the lower gear ratio titans run about 200 rpm higher going about 70mph than the other titans. thanks for the input.

**CaliforniaTitan** · 03-14-2004, 03:38 PM

yup...mine is 68-69 at 2k rpm with big tow and off road...

Have to report though...trip from san diego to Disney back home here to Hemet with most of that being spent at 60-70mph (lil slower than normal commute) we avg'd 16.8mpg.

Next weekend I will be making a trip to Sacremento so we will see what that looks like :-)

Excuse my ignorance... but can someone explain to me what "Overdrive" is exactly.

On a manual transmission, overdrive is when the engine is turning slower than the driveshaft (less than 1:1 ratio). For example, if the engine turns .7 revolutions and the driveshaft turns a full revolution, you have an overdrive situation and a ratio of .7:1

Where I'm fuzzy on "overdrive" is when it applies to Automatic transmissions. Most Auto trannies are "4 speed with overdrive" (except for the Titan, of course). I don't believe there are actually 5 cogs in the tranny in a 4+O tranny. Rather, I believe it's more of an "effective ratio" thing. 4th gear might effectively be 1:1 with a certain amount of torque converter slippage (there always is, unless you have a locking torque converter). Then, when "overdrive" kicks in, (meaning the torque converter locks), the mechanical ratio is in effect (which might be .7:1 or so). This is why you see the RPMs drop when overdrive engages.

If someone more versed than I about automatic transmissions could either confirm or clarify this, that would be great. I'm pretty sure it's correct, but I don't want to be the purveyor of false info!
