G's and High Altitude

My dad has a hankerin' for a G, so doing a little research on his behalf. My folks live up in the Rockies at about 8,500ft, and aren't far from Ouray, etc.

He loves older G's, but I'm not sure they will be a great option for him at that kind of altitude. Just hypothesis on my part.

I'd love to hear from anyone who runs a G at altitude, whether it's a 280GE, G320, G500, whatever. How well do they do? Struggle much on the passes?

He would most likely keep it stock, with 31-32" AT's. Wouldn't be heavily loaded, just one or two passengers with a day or two's camping gear.

Appreciate any input!

RE: G's and High Altitude

I have been up I think 10,000 or so with my 280GE.
Your're feeling the loss of power ...

My G500, going over Trail Ridge Road in RNMP ... no problem

Re: G's and High Altitude

Alright, I'm guessing everyone's going to keep saying "G500". I know I chose one.

I know my dad though. He has been working on Mercedes since the '60's, and knows them intimately. He loves the M110, for example, and loves to see a nice 280GE, as well as the W123 and W124 (he has three of 'em). He might prefer to get a W460 or an early W463.

With that in mind... how do they do up at altitude? Any experiences to share on those G's?

well, you are asking for it :-)

I 've put an supercharger on my M110 - from a 230K, replaced the K-jet with Megasquirt.
I am passing smog test in CO with flying colors

Re: G's and High Altitude

Could a person put a turbo on an older diesel to add power?

RE: G's and High Altitude

Well, having lived in and around Ouray for the last decade or so, I think I can answer your questions. The M110 gets pretty weak over about 11,000 ft. Mine was on 35 inch tires with 6:17 diff ratios and the getrag 5 speed. There were some obstacles on the Poughkipsee gulch trail that required some clutch slipping to maintain enough rpm to keep the engine from dying. Now admittedly these were pretty extreme conditions and the Getrag doesn't have a low enough first gear.

For anything less than that, the 280 did very well. It isn't going to be fast but it will defiantely haul you and your gear anywhere in these mtns, clear up and over the 13,000 ft passes. I also ran the 300GE 5 speed extensively and it does even better. The G320 was yet another improvement in power and capability. I would buy another 280 for use around here, not daily use but for trails and camping definately.

If he doesn't want the new G500 amenities and complexities, the Europa G500s are an excellent choice. The price of entry is not much higher and, then you have a daily rig that goes anywhere.

The altitude kills the power of every naturally aspirated engine I have driven at altitude. Forced induction rules up here.

Nods.
I remember my wife asking why the 280GE does poor in altitude and the A4 1.8T performs well. When I started talking about the difference of naturally aspirated vs turbo charged ...
She asked "why don't you put such a thing in your Gwagen".

Hmm, that started a PROJECT

RE: G's and High Altitude

Ah....So you put a turbo on your 280GE? How's the gain?

RE: G's and High Altitude

Actually not a turbo but a supercharger.
I am pleased with the gain, my goal was to just compensate for altitude, not to gain additional horses. And I don't have a dyno to test the output

However a friend who is a engine specialist for MB says it should not be a problem to get the M110 up to 200 hp, the M110 should easily stand that

The whole shebang looks like:

Not worth a damn above 5,000 feet.

+1
I drove a 1990 300GE and several early 1990's G320's, automatic transmissions, in the Alps, up to 9,000 feet.
I would not recommend them for road, the latter is a bit better but still lacks torque and power to keep the speed up.

By comparison, I can easily pass vehicles at 8,000 ft going uphill with my G500.

RE: G's and High Altitude

What a hoot. Your dad should base his decision on driving trucks, not on forum posts from people who go on vacation once a year or have a need to trailer 5,000 lbs at a time with them.

I live at 9k ft. 460 G wagens have been my daily drivers for 14 years in those conditions including a commute that's 40 miles and 4k ft each way 5 days a week. The M110 in the LWB 280GE was a great and willing participant for 7 years. I ran predominantly 235/85-16 tires, 4 sod manual trans, and 4.88 diffs. The truck was always a joy to drive on my commute as well as on trips all around the western back country from here to eastern California with the bone stock, well maintained driveline.

The fuel economy was not great at 12 mpg and on the heavier grades (7%+) the LWB 280GE was usually in 3rd gear spinning high revs. When that motor started to get a little tired around 330,000 miles I switched to OM617A with a 5 speed. The performance is the same as with the M110, but it gets 20-21 mpg all the time, goes 500 miles on the factory tanks, and goes up the big hills with less "sound and fury". I have a little over 100,000 miles on the diesel conversion and it still puts a smile on my face.

About 18 months ago a SWB 230GE found me. That one is fine too in the same use. Back to the high-rev life, but it keeps up with traffic and is a lot of fun to drive. I have another 617A ready to go into it, but it hasn't made sense to make the effort because the "baby G" gets 17 mpg all the time. So I just drive it.

At the end of the day, the decision depends much more on what your dad wants than on what anyone here thinks. I just thought all the talk should be balanced by someone being there doing that with 460s for the long haul. No disrespect to Harald, Dutch, or Oskar. I know and love them all. Just didn't want your dad to miss something he might like.

If he needs a test drive have him give a call or make his way over to Bailey one of these days. Hell, he can take either of mine for a couple weeks at a time if he wants.

All the best,

-Dave G

RE: G's and High Altitude

280GE is a rocket ship at sea level, no problems spending all day in the fast lane, once over 5,000 ft elevation its slowing down and the vehicle takes on a different identity entirely. The M110's "turbo boost" feeling @ 4000rpm and above dissapears and you feel like you are driving a tractor.

300GD always feels like a tractor no matter what altitude, adding a turbo motor just makes it a 'really fast tractor'.

G500 is scary fast at sea level but just right at altitude, its definitely the jack of all trades as it does everything a 460 can do and more.

I've used a 617.950 and a 617.951. My brain knows which specs and parts are different, but my butt can't really tell the difference.

Wow, Dave - that's really great. Thank you. Exceptionally generous of you. To be 100% honest, I can't see my dad taking your G for any appreciable amount of time - I could possibly see him going for a 10min test drive with you, if only to ride shotgun, purely because he wouldn't want to dare to drive another person's G for fear of damaging it or even operating it in a way that you wouldn't like. He's just like that.

I do appreciate the comments - maybe because they were the new/current G when he was younger, he loves W460's and I could see him going for one because it's old school just like he is - no fancy electronics, built in a manner that he understands with components that he is already familiar with, classic old school Mercedes engineering. I bet he'd go for a 280GE over all the others, or perhaps a 300GD.

I appreciate all the help, thanks guys!
