Top Speed
Top Speed
So I was late driving back from Los Angeles trying to cover 130 miles for the 3:30pm kick off at my friend’s Super Bowl party. Cruising 90 miles per hour plus, topped off just over 100 mph.
Never looked into this and it got me thinking while driving.
So how fast can a 617.95x go?
It seemed at a 100 mph I still had plenty of pedal cruising travel on flat land and this is with a 2.88 ratio differential. Didn't want to try any faster because CHPs are lurking.

On I-5 in the central valley, I've been up to ~108, floored on flat ground, but it took a while to get there, that was right after I got the 300D and my wife (then fiancee) was living in Sac... I could get it up over 110 going downhill, but that puppy was screaming...

Max speed for my 300TD with the 2.47 rear was about 105, with the 3.07 it is maybe 108-110. This is with 225-55-r16 tires. If I get substantially more power out of the engine the 2.47 will go back in.. 140mph in a 300TD, imagine that!

GREASY_BEAST 140mph in a 300TD, imagine that!

I've had mine pegged downhill on the 14 south to the point where it could go no faster, but the speedo only goes to 85. haha
I haven't tested my top speed yet but I have been able to cruise at 75 mph on flat in my G with no headwind.
When it had the gas engine, I could run at 80 all day.
Maybe by summer I can get the 5-speed installed
(02-09-2010, 01:01 AM)SurfRodder I think that the 2.47 would be a manageable ratio. we'll see I guess!

I have yet to test my car's top speed with the new(er) engine. My NA euro 300D would hit 110mph (if you trust the speedo). I could easily bury the needle on my NA 300TD (90+).
My 240 will easily peg the 85mph speedo despite the throttle stop screw being turned all the way out. The 300 revvs out at 96mph because of the 3.46 rear end and torque converter slippage, but it gets there pretty dang quick!

When I used to have a w123 240d in '98 with 4 speed manual it would go to 100mph.
A n/a 300d my friend had would hit about 112 mph. It was a 4 speed manual as well.
The fastest I've been in my w201 2.5 turbo was about 122mph completely stock. It's a 5 speed manual. Now I haven't tried it as 1. Here in Albania it's not really wise to drive that fast, 2. My egts climb up pretty fast after about 100 - 110 mph.
(02-13-2010, 08:06 AM)bmw4aaron What gears are you running in your G? I have 4.9 and don't think I could cruise at 75, not to mention 60 is about all I can get up to here in the mountains.

I have been at 100 a few times, the RPM range is about the same as DV's. The thing that scares me is the sway in the rear end - I attribute that to the baloon tires.
Once I have the motor dialed in I think I will go to a higher range to keep the RPMs down a bit.
The `83 300TDT OM617.952 I had, I got 195 km/h(121 mph) with only adjusted ALDA, when I adjusted the torque, It easily drove inn 180 km/h(112 mph).
Automatic transmission, original rearaxle.
My `91 300TDT OM603.960 I had 218 km/h(135 mph) with, still original.

On topic... I've been to 110 or 105 in one of my '79 300SD's. It's been a while and the one I have left only hits 95 or so. For other reasons, I think the IP on it is FUBAR....
(02-16-2010, 02:10 PM)DeliveryValveI wish, Some idiot has mounted a 300TE 3.27 ratio diff, so the real speed on the picture is about 185km/h or 115 mph.(02-16-2010, 09:47 AM)Einar My `91 300TDT OM603.960 I had 218 km/h(135 mph) with, still original.5000 RPMs, with a 2.65 ratio diff I take it?

Not sure - I went on a day trip today and was cruising at 75-80 most of the time. I have 31" tires and stock diff gearing and 722.4 automatic with 1:1 top gear. My mpg is super low though. Averaging about 14.7 mpg because I'm often driving with full throttle.
The truck slows to about 60 on the typical highway ascents and can hit 85 on descents.

I know I'm digging this thread up, but I had a related question... I am running 35" tires with 4.88 gears in my g wagen and am also using the g auto and torque converter. I have a set of 6.17 gears that i want to install for lower crawl speed off road, better driveability etc.. and this returns the vehicle to nearly a stock setup in regards to gearing vs. rpm (28" tires stock). I would like to be able to drive 110kmh ( 68mph) on the highway but could live with 100 (60mph). I would be turning around 4000 rpm for extended periods, will this be ok other than the noise?
