Just as the Thread's Title imply's. At what speed does your car feel the most comfortable cruising. Usually while on my way to work i'll stick it right at 3000 rpms (80 mph) and i get around 19mpg. I get a nice smooth ride as well.

90ish is the sweet spot

 

Yo,


80mph easy. 4,000rpm with the GTUs rear gears and special 5th.

80mph..........


-Shawn

 

around 3000-ish rpm

 

For law enforcement reasons, I cruise at 80. But, my car prefers to be cruising at 95.

 

when im going on long trips i do around 90ish but short trips i do like 80ish

 

90's the sweet spot...

 

Ha, "for law enforcement reasons I go 80" . . more like 70 around these parts. Or maybe I go slower because my car is too bright for a cop not to see.

 

On the trip to SevenStock, I cruised mostly around 90MPH on I-5. Felt like it could have been happy going faster, but I like having a license. Got 24MPG at 90, BTW.

 

~80-85 mph

 

when the manifold pressure is around -100 mmhg to -50 mmhg.

that means the engine is not boosting (wastes gas) and then it isn't fighting agianst the vac.

that gives best mileage

 

You got it. I go by KM/h, and I like around 140, which I think is 90mph.

If you're looking for mileage, I would say 62-68ish is the best

 

I find that at highway speeds the faster I go the better my gas mileage is (I have an na, not sure if this is the case for the TII owners). Not usually the case with other cars; they tend to have a mileage sweetspot.

As far as comfort goes, 140kph or about 88mph, you're out of the drone zone, the car seems happy at that speed, and if it's raining and you have some rain-x applied you don't even need the windshield wipers.

 

about 3200 rpm, I think 90mph in top gear... hell, who looks at that stupid guage anyway...

 

Seeing that it shakes over 90 and that right now the boost is stripping my clutch, I would say I cruise at 70... Gotta get my damn clutch installed.

 

A couple facts:

~i have a '89 GTUs....

~80mph in 5th gear for me is just over 3500rpm....

i here from you guys that 80mph should be 4000rpm and if that's true then that means somethings up??

 

cruises at 170km/h nicely

 

You should be even higher than the other NA guys because of your GTUs rear gearing.

 

80 is at 3200 with 4.1 gearing. ~ 3500 with the 4.3 GTUs

People with 4k rpms 80mph are probably in TII's.

 

I'm at 3000 rpms right at 80. but im NOT useing stock sized tires

-Markus

"So it should read 3200 rpm?"

 

80ish here too

 

I did 115 between on a trip to knoxville last night. Light traffic, 3 lane interstate, light to no enforcement, valentine one in use, turbo under the hood in case I need it too :-)

Top up of course, the car couldnt be smoother. Seriously, there is ZERO NVH difference between 80mph and 120mph.

 

80-85mph. She's quite happy at 100 or so, but I usually travel during peak time so 3 digit speeds aren't possible. Stupid Midwest.
