Stock performance

Hello,

Let me start by introducing myself. My name is Jake and I got hooked on Benz when a friend bought a sportline 190. Ever since thats basicly all I've had. Other then my dodge cummins. I own an 85' cosworth and an 87' 190D.

I've been reading about stuff that can be done to the 602 for it to put out more power. The 16v I'm restoring so most of my cash flow goes that direction. With that said, If I turn the pump up all the way can I put on an He221w turbo and be safe or do I need atleast 6mm elements?? if I can just run a turned up stock pump and a bigger turbo can the trans in that car handle it??

Thanks much for the help

Jacob

I know how to build a cummins and I thought that the M pump would be somewhat the same. But I was sorely mistaken. So to the forums I go to get some power from a great diesel engine.

When I saw the thread title I thought about my 401k and how much mock money my team made in junior high off Matsu****a and Berkshire Hathaway when we played the stock market game.

My limited knowledge of Mercedes diesel performance tuning is centered around the OM617, so I can't answer your questions very well. I do suggest EGT and boost gauges before you go messing with anything. Also a transmission temperature gauge if your 190D is automatic.

Edit: LMAO at the forum's auto-censor of the name of that Japanese industrial firm.

Heat is going to be your #1 problem, as you probably already know. The basic stuff that applies to pretty much any of the diesels:a nice intercooler, correct sized turbo, a free flowing exhaust pre and post turbo, and proper timing (advance it until it knocks, then retard it 1*-2*)

If you want some extra power without spending the money on IP work you can setup methanol injection for around $150. It's worth 20-5,000 HP depending on who you ask

Stay away from propane with IDI engines you risk preignition.

I was thinking of no intercooler but running a low to moderite larger turbo and run less boost to keep temps down but still move more volume then the stocker. Any suggestions on this hx30 etc. An intercooler costs arent cheap even more so when u have to modifiy the intake to do it. And use methanol set to low use just to keep the temps down in the respectable range.

An intercooler is always a good Idea or Water to air but those all cost alot and body mods are not something I want to deal with. I was thinking of running a slightly larger turbo so I can move more volume but keep the boost(heat) lower. And running a meth kit can act as a cooler of the intake charge being that Im not shooting for crazy numbers just better then stock. I was looking at maybe 180-200. that would be plenty

Hi,

my proposal is to start the other way round: get the pump done with larger elements and keep the engine stock. Then decide if the output is o.k. and continue from there with turbo and IC.
I personally run 8.5mm elements with stock 603a engine. No idea about hp but could already be near your hp goal. All that smoke free and all temperatures safe with astonishing economy.

Find a diesel shop in the US that can do the pump and come back to me for elements.

Tom

My point is being missed, I don't have the funds to spend 1500-2000 on a pump. I'm not looking for insane numbers here just what ever the pump can handle.

I don't remember exactly. This was back when Senior Bush was in office. I remember we did well.

Your engine can put out around 130hp to the wheels with the pump maxxed out. Its going to take a new pump to make any more than that no matter what turbo or tuning you do to it.

At some point

In your Improvements to the w201 190D you'll EXCEED the capacity of the
722.4XX Tranny. Start looking around and do your D.D. for which 722.3XX
Tranny will fit BOTH the W201 and the OM602 version you've got.
