Drove the Xb up to Boone, NC monday. The little 1500cc engine huffed and puffed straining to go up the 8% grade on US421 climing to probably 3000 ft elevation. Could only muster about 40mph in 3rd gear.....2nd gear didn't do much except rev the heck out of the engine....

Having been to colorado before, I can only imagine how slow the Xb would be at 10,000 feet elevation.......

 

And that, my friend, would be all the excuse that I needed to convince myself to get a supercharger... hahaha

 

^^lol, def, i actually live in the mountains, not to that extreme, but have never had a problem with getting around

 

How much of a load was in your box?

 

passenger weight = maybe 650 lbs.

 

I ripped all around those mountains.. I had no problems at all with it lowered on huge heavy 18s. I did have an intake and exhaust. Granted it wasn't the greatest hill climber, but if you kept up your speed, it was fine. I never had any issues that downshifting and punching the gas wouldn't help. I did the 6% grade on I40 between Ashville and Knoxville at 90mph plus.

 

Put in 3rd and hit the Nos. HA HA. Even with the AEM intake and TRD extuast I find it alittle sluggish on the hills too!

 

I was just in Colorado at 14,000 feet and had no problems any part of the way up. Load was around 400-450 lbs.

 

I did use the OD/off button for climbing and decending.

 

I live in Colorado. I don't have that problem. Were you doing it in reverse?

 

Add a header on your box and try it again! :D

 

Been there done that. Our boxes have a hard enough time pushing their own weight up a hill - much less 650 lbs worth of passengers.

Downhill is fun though.

 

Yup, I had the same problem going though the sierra mountians from my trip back from Las Vegas. the elevation of 3000 ft. -4000 ft. was a though one to get though... and yes... it convincved me too to get a S.C.

 

That's funny. Yeah I live in Colorado. Take the box snowboarding all the time, it zips right up. I think the huge difference is MT vs. AT. I also have intake and exhaust. I'll tell you one thing, it smokes the hell out of my old 4runner!

 

I had an 89 4Runner witht he 22RE 4 cylinder, 5 speed, 4.37 gears and 31" tires that I went exploring the Silverton area on CO and man it was tough at those heights.

 

Oh yeah... forgot to mention my xB is a 5-speed.

 

haha now thats a classic

 

Where the heck are you in Colorado? There are a handful of peaks above 14,000 feet (RedCloud, Sunshine, several others), but I didn't know any roads got up into those elevations. I know Pike's Peak has a road to near the top, but I didn't think it was 14,000 feet.

14,000 feet probably would be tough on a little engine.

 

Meh. My 5 speed topped Guanella pass, 11699 ft, no problems. Two adults, two kids, gear- call it 500lbs. And it didn't have any issues keeping up with traffic on the climb up I-70 to Georgetown getting there, either...

TRD axleback and TRD performance air filter didn't add that much, I'm sure... Midgrade 87 octane Conoco- averaged almost 33mpg...

 

Yeah I definately am not used to being above 4k RPMs at highway speeds but in the xB it seems to love the revs... still makes good MPG doing it.
