Slow acceleration

[Benz Kid]

i have a 1983 300d turbo and when i hit the throttle it takes a little bit to get up to rpms. its just like a slow resonse. i know it should go up quicker cause on all of out tractors (mainly all deutzs) when you hit the throttle...BAM! it's there. and also if i try to do a burn out with it, it takes about 15 second the wheels break loose

Same deal with my '83 300SD. I'm still trouble shooting what the cause is. I just installed new Monark nozzles and no change. I run regular pump Diesel with some DieselKleen cetane boost every fill up. I average less than 20MPG with mixed driving.

Last night, I disconnected the ALDA and plugged the boost line to test the ALDA. Not much change in performance. Starting off is the same and I have a bit less power when up to speed than with the ALDA plugged in. ALDA screw has been adjusted about 1/4 turn out. No change in performance.

Make sure your throttle linkage is nice and tight. A lot of times they will get loose with age, also you can adjust the Alda to give more gas until boost kicks in. It's all air and fuel delivery, check filters etc.

Well, surely "you know" it should get up quicker...............

But, do you "know" that you have a turbocharger...........and do you "know" that the turbo must spool to over 100K to develop boost...........and do you "know" that such acceleration of the turbo cannot occur instantaneously?

I'll tell you what I know:

A large V8 powered sedan is in your future so you can get to the next red light faster than all the other DB's on the road. Gas is free............right?

All I "know" is that the above post was rather unhelpfull.

Try cleaning the banjo bolts and hard line fronm the ALDA to the intake manifold. They get clogged with carbon and cause low power. Also make sure none of your brakes are dragging, all your filters are clean, your valves are adjusted, and your throttle linkages are lubed and properly adjusted.

yea my linkage is all good and tight valves were rechecked last week banjo bolts were cleaned a couple months ago and i know what turbo lag is!

I tell y'all something I "know" as well. My F250 with the 7.3 IDI will jump off the line faster than some newer trucks. Whatever I have in the front of the truck quickly finds its way into the back seat. Granted the engine is over 2x the displacement as the OM617 but the truck also weighs 2x or more than the W126 chassis. My turbo lag is not bad, either. The Banks always feels like it is right there as soon as you touch the accelerator. Now, I can floor the 300SD and it just lethargically gets up to speed; from my observations of other OM617s, that is not normal.

I'm not looking to make 500HP out of this engine but I would like not to have to plan my turns to compensate for the 5 or so seconds I may or may not get some little bit of power to the wheels. I'm sure Benz Kid feels the same way.

It's an age thing. Once you have to start dealing with 'turbo lag' on bodily appendages, real turbo lag seems insignificant by comparison.

It doesn't "seem" insignificant.

It "is" insignificant.

Such individuals should drive an n/a diesel vehicle for a month. Then they might appreciate what they have.

Or, they should simply buy a 300hp gasser and beat the next DB to the red light.

hey, a 606.912 isn't that slow!

...........now there is a turbo that takes forever to spool............

You're not going to break the tires on dry pavement.

What do you mean it takes 15 seconds for the wheels to break loose? You chirp the tires going into third? I don't think even a 560SEL can manage that.

I think he's talking about a brake stand. If you hold the brake and put the accelerator to the floor, the rear wheels will break loose and spin. I can do it on my car with the A/C off but the wheels don't break loose until about 15 seconds.

Yes. It was unhelpful.

Buy a 240D, no Turbo lag, instant power to the rear wheels when the clutch is released. Problem solved.

The intertaining part is, the DB that was behind me trying to launch his V8 Rocket into my trunk, is now ahead of me at the next red light. I roll in behind him as the light turns green, and off they go again, and I just keep rolling along w/o stopping.

These old Diesels are not fast off the line, but are long lived and dependable.

X2 on cleaning out your boost line from the intake manifold to the switch over valve and on to the ALDA. there could be a problem with the S/O valve, and it is leaking the boost.
