Whats next diesel drag racing?

Any idea on the hp on a N/A 603? Ever since I have had this car, I have been reaching the 9-10 second range (hard to get it to tenths or hundredths while shifting the 5 speed and watching the laptop for the gps mph numbers). From what I have read here, those numbers are just a "bit fast". I should just lay down the funds for a g-tech pro or show up at a open night at the local drag strip...

91 190E 2.6 5 speed 220k miles and this car still scoots!

it was bypassed when I got the car, and I have not repaired it. I have put about 4K miles on this so far, and I have been cleaning and repairing items for a while now. but I was not really concerned about the OB, so I concentrated on other things. lots of threads say to time the 0-60 so I did it, and GOSH I was supprised. I just hit the stopwach when I punched the pedal, then clicked it again when the needle hit 60... not exactly scientific, but it should be close enough.

Are you sure you're on a level stretch of road when you run the test? I'm always surprised at how quick my car feels on even a slight incline (or would that be a decline?). Just like I'm always surprised at how SLOW it feels with an extra person in the car...

hehe... this thread caught my attention because I thought the W123 turbo was the slowest thing I've ever driven

I still love it though

On the tech board, when speaking of engines haveing a "Sweet Spot", I mentioned that I was able to get 28 MPG averaging about 80 mph from my 84 500SEL because that was where its "Stweet Spot" was. I was told it was impossible, I must be stuped because I must not know how to figure MPG, I was just flat out lying, etc. I won't go on because I believe you get the idea.
Well, Your car is probably set up corectly, has above average power, everything is working as it should, and you are blessed with a great SD.
Every car different. It makes me feel good when someone has a great car and is proud of it.
By the way, no one, I mean NO ONE ask "How did you do that? Would you give away some of your secrets? So I just droped it and deleted my messages because I don't liked to be told "You don't know what you are talking about?"
If you want to sell that SD, let me know. I may be interested.

I don't know, I think you are all crazy. I can't beat 19 seconds with my car, and I can hit 100+ no problem. Maybe you're all in some alternate "slow time" universe or something and I'm the only one with an accurate stop watch.

Then fix it.

Brians SD runs just about as good as a 617 can run. I have seen a huge number of 617's and his is one of the strongest. Also said SD's 0-60 time was measured with a G Tech Pro, this method is about as accurit as one can get without hooking $10k worth of test gear inside tha car.

You can pretty much bank on his 12.7 time, thats about as accurite of a number one can get.

Sorry unless you have some mods I don't buy for a second that a stock 300SD will run 0-60 in under 10 seconds.

I'd shoot for 12-13 for a perfectly tuned stock car. I mean timing dead nuts, turbo putting out stock boost, everything tuned to perfection.

The people that frequent these boards are realists. They like to see proof of how something was accomplished, and how they could manage the same with their cars. I can empathize with them. But for now, I'll take your word for it.

My SDL runs to 60 mph in less than 9 seconds (on summer fuel). That much I'm CERTAIN. If I can figure out an innovative way of securing the GPS and digicam properly, I can prove it more concisely (tried to even present the road grade visually).

I know for a FACT that the IP rack has been advanced (at full load), indicating a full load stop increase. The idle was retarded along with it. One screw turns the full load out, the other keeps the idle at a reasonable level. Both NEED to be turned at the same time to compensate for each other. I have not touched the internals of the IP (mine) myself, but I have compared one IP to another IP (spare rebuilt from my father). The latter I have heavily tweaked. But I always document my tweaking so that I can revert back to stock settings.

Anyway....Do I believe you, about the 28 mpg? Sure I do...
Do I believe an SD can accelerate to 60 in 9.55 seconds? Of course...
Have you given me reason to doubt? I have seen some E300's that give E320's a run for their money, and some 560SEC's, US Spec, putting out almost 280 crank hp on the dyno. Search the archives over on benzworld, this is the truth.

There are so many variables to the equation, anything can be possible and frequently is.

125hp is 125hp, simply no way around that. Of course cars are not like computers and results may vary. Now if he said 11 seconds and his fuel and boost were turned up, maybe timing played with a bit, then I'd beleive it.

Your SDL is not stock, so of course that changes things. Plus 603's are up 25hp on the 617's, assuming everything is stock.

For example their is an argument that if you retard IP timing to 14ATDC on a 603 you might gain a bit. Mine is at 15ATDC, may or maynot knock another degree off that, I'll let the TC break in first.

So lets do this for this hot SD. What is your turbo putting out? What is the IP timing? What is the cam to crank timing? I am also assuming that your injectors have been checked and are in proper order. Valves adjusted goes without saying. What about the ALDA? Is the cap still on it or has it been played with? Can you get it on a dyno for some numbers?

Now most 617's I see have original injectors, never touched, timing never checked, ect. They are out of tune and tired, period.

I hope you mean BTDC (Before Top Dead Center).

Nope.

603.971 15+/- ATDC
603.970 14+/- .5 ATDC
617.951 15 +/- ATDC

All using RIV method, 603's can only be timed with the RIV.
617.951 using drip method, +24+/-1 BTDC

RIV. I see.

Don't confuse the timing method with the actual start of delivery. Apples and oranges.

As far as I can tell, those numbers are the start of delivery, thats what the RIV light indicates.
