@3000rpm

[Simon]

This was born in another thread!

Just out if interest and I know they are very different cars, I thought I’d compare my C180 at 3000RPM to Brian’s E320CDI.

Brian’s: 3000rpm = 110mph

Mine: 3000rpm = 67mph (5th gear manual)

What speed do you do at 3000rpm in top gear?

Drive carefully when checking.

 

[GrahamC230K]

Can't remember spot on, but I think it's 80mph.

Will let you know for sure tommorrow!


EDIT: Just checked a prev. thread. Def 80mph @ 3000rpm for me in 5th.

EDIT EDIT: Just made me think. A 6 speed would be nice

About 90 at 3000 revs in 5th. Drop down to 3rd at 90 and it really flies though :bannana:

Bet Brian gets 35 to the gallon at that 3000 while I get 22ish

90mph is flat out in 3rd for me! That's when I change to 4th and hang on to 120mph. So I have calculated theoretically of course

 

[V12]

I can get 140mph in 3rd, but that is with a 4-speed...

I'll check tommorow to see what 3000rpm brings it upto.

Well, I get to 4000 in 3rd at 90 so still 2.5k revs left to go which is nice. Can't better V12

Get to 155 without too much of an issue though :bannana: (twos in France by the way).

V12, you must be limited too! What will it do without? I have been told about 175 in mine.

Graham, I have a friend with a C230K and it shifts really well, much better than my C240 ever did. Was thinking of swapping for a C43AMG as i just love the C class but the wife did not hence the CLK

110 at 3000 rpm.

1st @ 6000rpm = 37mph
2nd @ 6000rpm = 80mph
3rd @ 6000rpm = 125mph
4th @ 5500rpm = 156mph
5th @ 6000rpm = 156mph

 

[GrahamC230K]

Shude,


I would be intetrested to know how your electronic 5 speed auto compares to my manual.

Roughly:


2nd @ 6000 rpm = 59mph
3rd @ 6000 rpm = 90mph
4th @ 6000 rpm = 120mph

I very much doubt I will be able to give you those figures because I think it shifts before I hit 6000, I can certainly try tho' . In my experience you have gone beyond the power band at 6000rpm and are well into the "noise band" instead! I think if I keep the kickdown button depressed it will keep on gassing until the very last second.

I will try on my way home, if I remember, although 120mph may be an issue unless I really try hard on the twisty A/B roads. If I don't post a reply later it's because I'm in a ditch, burning in my car.

 

[GrahamC230K]

When I say 6000rpm, I mean near enough. I think the limiter actually hits at about 5900ish.

I know it's not the peak power, but we are talking max. in gear speeds.

Of course I do.

However I am Limited to 4600 rpm max on my diesel, compared to your 6000 rpm petrol.

So equivalent is 3000 rpm Diesel & 4000 rpm Petrol approx

Just a nats nad under 75mph @ 3000rpm on mine.

Interesting that their is a variation on the C's here, I would have thought the autoboxes and diffs would have had the same ratios but obviously not.

 

[V12]

Fudger, ive been told by some very reliable sources, that without any modifications to gearing etc, just de-restricted, it will reach exactly 169mph. pretty good goin i think from a 2.5tonne car.

As it is a pre 1995/96 model it only has a 4 speed auto instead of the later 5 speed...

Feels solid at 150, not even breaking a sweat.

 

[Fudger]

V12 m8, I bet with the correct/approapriate gearing you could do 190+. Clearly, the engine is not the limiting factor.

I have heard of a CLK430 doing over 190 with only gearing/diff mods but it is only 1.55 tonnes in weight.

Jimmy, jsut goes to show why jumping from one C to the next can seem completely different!

 

[Fudger]

V12, just clicked on your sig link. Nice tune man :bannana:

Have you called the AA m8?

What model car is it V12? As its pre 96 I guess not the one in your sig?

 

[V12]

Technically it is a S600C, but better known as the CL600.

Being the 600, it is fully loaded and we have done some subtle mods + fitted 20" alloys to finish the car off.

BTW, it is not technically my car anyway, i just drive it

Fudger, i have heard of these doing 180 with brabus modding the diff...
I have researched into it, and there is nothing that has big enough flange sizes with a lower ratio. basically, i can only improve acceleration by changing to another standard diff.
Would need someone more clever than me to internally change the diff, which would be expensive.

Or I put a later 5-speed box in, which i already have, they claim about 175 from it, with much smoother shifts etc.
Of course, it needs de-restricting too, but when do i ever use that power.

Never even had it to the limiter while i was driving, but been the passenger in germany with the speedo reading off the clock (160)

My daily car at the moment is a 280CE (123) and it is slow after my 190 and 600.

 

[Shude]

well, the engine and gearbox didn't like it but I tried these out.

2nd @ 5800 rpm = about 55mph
3rd @ 5800 rpm = about 85mph

I didn't do the 4th or 5th gear test, although I can tell you that I reckon at 5800 rpm in 5th it's prolly going to be doing about 150mph-ish, I did 145mph and it was at about 5500, still had a little bit of "go" left in it.

btw my car does *exactly* 80mph @ 3000 rpm in 5th.

I have found that I get very good fuel economy at 80mph, however if I go over 80mph the fuel goes VERY quickly, it's like a switch, 80mph == good; 81mph == awful.

 

[Koolvin]

Just under 80MPH for me.
