DB, I invite you to come and time my car anytime, better yet I'll even let you drive it, but if you break it you fix it. ;)
I still have no idea who Mauri H is.

I found that to be strangely arousing... what a sound... mmm mmm need to get out for summer to get the 240D...
~D.J.~

I'm pretty sure he is one of the Finnish sorcerers who constructed a super-turbo. One of those 400 + HP monsters.

I'd like to try that puppy out, unfortunately the trip from NH might be a little off course from my route to work.:P

Mauri is from across the pond, since he has a 1992 wagon with an OM603, which was never imported to the USA. If he built one of the 'super turbos' like the Finns did, he could be telling the truth. Y'all have seen the 'dieselboost' video, right? Guys running intercoolers larger than the radiators (!) and about 30psi boost from a giant Holset turbo? The only thing stock on those engines is the short block...!

:P

BTW - factory spec for the 300SDL, per the sales brochure, is 0-55mph in 10.4 seconds. There is no listing in the TDM for acceleration data for that model, or any 126 diesel, which I always thought was odd. Anyway that translates into about 12.0 seconds for 0-60mph.

The older 300SD weighed almost as much but was down 25hp, and usually runs about 14-15 seconds 0-60. The official specs in the TDM say the 126.120 is 15.2 seconds from 0-100kmh (62.4mph), or right around 14 seconds 0-60. Those are for BRAND NEW cars putting out full rated power... not 20 year old cars with 200kmi on them. :rolleyes:

If y'all are getting 10 second times in those boats, I want to see photos of your propane injection systems.

:nos:

VIDEO TIME!
I will try to make one tonight for ya guys...see if I can mount the camera somewhere better than in my hand (little shakey..its cold out!)

Dave, what do I need to do to convince you of my car? I don't have the money or time to do a dyno run, I don't have time to make videos anymore.!:P

Heck, I just recently started driving a 300SDL black with gray hood 300SDL with poor injectors. Next time I have the chance, maybe in a couple of days, I'll show you one that gets up there in about 10 seconds. It is a federal straight-pipe SDL, so it is wide open front to back and sounds mean.

This time I will try to shoot inside and outside the car. BUT for non-believers, I will try like heck to use the camera to fix on the GPS and the road ahead to show how level the road is at the same time. This should help to clear the air a bit.

0-55 mph sounds pitiful. Was this the '87 sales brochure Dave, or '86?

DO IT! The more the merrier.

And, after I'm done, I will shove this video in Dr. B's face, lol.

C'mon Dave, be reasonable. Why wouldn't it be possible for a 300SDL to have 20 - 50% more power than stock without modifications.:rolleyes:

No, I understand your skepticism. My propane system is a new IP with a cranked up ALDA, new injectors, Power Source DK, and a heavy foot for 50K miles full of romp'em stomp'em driving.

Tried...too dark for the camera to get a decent fix on the speedo. Hard enough to switch gears, watch the video and keep it centered, keep the car on the road, watch out for stuff...and yeah
heh.
.I will do one tomorrow when I wake up...whenever THAT is :cool:

Videos
 

Here are some videos of Finnish SuperTurbos for comparison:

Yes, they are Diesels.

Enjoy

I've seen most of those before... I couldn't open the first one though (codec error, something wrong on my PC). The one of the 124 doing cookies and frying the tires is awesome though:

http://students.tukkk.fi/tuukka.simonen/Mersuvideot/std.wmv :D :D :D

BTW - I think Mauri is the same Mauri with the SuperTurbo that's the forum moderator on the Mersuforum.net. And for him, yup I believe his acceleration claims... (you SEEN his engine? OMG!)

:eek2:

Just to explain my skepticism... I have found that most MB diesels simply don't perform better than the factory specs, most are slower, and very few are even equal to factory spec after 20+ years of wear and tear. This assumes a stock configuration of course. Quite often it's the measurement methods that are inaccurate. But, a stopwatch & GPS should give pretty accurate numbers. Anyway, a genuine 10 seconds 0-60 from a W126 would require at least 10-15% more power (probably 160-170hp) than a stock 300SDL had (148hp), and the SD is down in the 125hp area... hence my skepticism...

BTW - sales brochures were 1987, but there was at worst a 5hp power difference from 86 to 87. Mercedes listed 0-55mph because that was the national speed limit back then. Later brochures (90's) list the usual 0-60mph.

:P

I think the first video is of Mauri shooting a 14.69 sec 1/4 mile @ 166 kph--~102 mph. Not too shabby for an old smokey diesel.

Makes sense. I understand. But I assure you that some diesels are that quick. I use GPS, a Garmin 72 with WAAS. I use a stopwatch to time my launches(for instance 0-30 mph foot to floor comes up in 3.7 seconds without power-braking). 30 - 50 comes in at 1.65 seconds, 50 - 60 comes in at 2.62 seconds. I clocked it with GPS and stopwatch for my own authentication.

A few cars that tried to race me and lost(mostly due to merging traffic paranoia).

A 99-02 Chevy (Vortec of course)1500 LT ext. cab downhill 40 - 55 mph, 2000'ish 4.2 liter Dodge Dakota 4x4(Kinda even, but I pulled past him at 95 mph(this happened at the Spaulding Turnpike Rochester tollhouse). Another 99-02 Chevy 1500 LS trying to cut me out at a merging onramp, lol.

HP is not what is going to get you to 60, its the torque curve and differential. For example, the 350SD was rated at 134 hp and 229 lb/ft of torque. It could get to 60 mph in 11 seconds and had a top speed of 108 mph according to factory spec sheets.

I did a little thinking later and I'm came to the same conclusion that it might be one of those Finnish guys tweaking a diesel MB so I take back my comment about the car in a hurricane. I've looked in to their work and even made a made a little sense of their Finnish postings in their forum and I am very impressed by their work. I'm more than sure they have a good bankroll to fund their projects as well.
I drove my diesel last night after it sat for a bit over 2 weeks. It seemed the tranny was acting up a little again. It was shifting early again. DB, I guess I'll have to work the bugs out before you give my 300D a try if you find your way out to the NW anytime in the near future. The invite for you to try it is open anytime. :)

Gsxr, would you be as skeptical about a 123 not in total stock configuration with some tweaks?
