So i found a shop that has done a MB diesel pump before and quoted me 1k labor to slap in elements and tune the pump on the bench and then have me test it in a car then bring it back for retuning.

Now what to use M or MW ....floyds or hollys?


How do we keep this under 2k guys? These people said they had a guy spend 4K in pump modding for his 300D and they said they gave him TOO much power as his motor lasted only one month then blew!

Now i know as well as you all that the guy prob didnt do anything else to the car and it might have had 350k on it and been on its last leg.

So what do you think?

I got gsxr's done for $700 plus soft parts and shipping.

This is for M pumps only!

He had both pumps though. If you have to order the 6mm elements and delivery valves new they are about $700. Be aware though the last time we checked stock on 6mm elements and DV's they were on backorder from Bosch. They would have to manufacture more and I did not get a lead time. If you order the new parts labor goes down to $600 (don't have to disassemble and check).

Well, it sounds right of the bat that he may not be THAT knowledgeble to have spent that much AND blown an engine. Obviously I am all about finding a stateside source but maybe we can get more info and/or have him post on the board. The knowledge here will help him get it done properly and without spending that much most likely.

This guy that supposed had it done didnt know that much just had it done to his dodge truck so had the shop do it to his N/A 617.

I dont know what elements to use ......i have both M and MW pumps laying around in great shape and i have a donor 603 M pump from an 87 300d.


I just want 160-200hp at the rear wheels.

This shop sounds like they can do that as the guy i talked to said they had multiple bosch machine so they can fine tune it. They said they would set it how they think and then have me test in in the car and i can bring it back for more tuning.

I basically want a pump for just under 2k done.

This guys ONLY do diesel injection tuning so i think they are my best bet and 1k for labor is the going rate if not more.

I was going to have the back east do mine but no one has heard from him and i fear turn around would be like a year or more.

Can I ask a daft question?

(I sure can)

But what on earth are they planning to do to your IP pump - what is actually involved in this tuning process?

Don't leave that there - I'll take it to bits!

Besides using a flow bench and replacing worn parts i dont know?

I explained the myna pumps and that we should be able to do it here in the states.

The guy who spent 4k on his pump though wanted the most power he could get. They gave him that and his car blew. Now im just looking to get a taste of that kind of power.........with good idle and mileage. I think 160hp on a healthy 617 turbo motor will be fine in the long run as they actually did over build these motors.

If these people have done as many P7100 pumps for old dodge trucks then our pumps should be a piece of cake.

Thats enough for them to trust they will play with the pump to make it wright.

Also i have enough motors to test with

What's the name of this shop? For your HP requirement, it's a toss up of which pump to use. But If it was mine, I'd do the MW with the 7mm Holly.

With that said, winmutt may have a line on Chinese 8mm elements for $11.50 each that a few of us are interested in a group buy at SuperTurboDiesel if you want to take a chance on them.

So talked to the shop in nor cal and he is going to get back to me on which pump he thinks will be the easiest to mod. So far he doesnt like the fact the MW pump has the (rw) governor as he said its hard to fine tune whatever that means.

That means he does not have an understanding of its operation beyond Bosch training. In reality that makes sense given the shops only do inside the box, "by the book" work.

Have him put in the new elements and balance them at the standard rack positions, forgetting about the out put quantity. Have him set the idle out put as he normally wood, (this will require the Idle governor to be set at a different position, but all that matters is the out put at a given pump RPM). Idle stability may be an issue depending on how he sets the Idle Governor, but I can walk you through how to get it right.

Then have him set the Rack Limiter to out say 25% more fuel that stock ( you can always increase it), and set the torque control and high speed settings as he normally wood, (basically he looks for the rack to move at a certain RPM).

This would give you a stock governor that is very drivable and will put out 25% more fuel at full throttle until the governor starts backing it off. Your rev limiter max speed may end up being higher as well.

At this point, depending on your turbo and such, you may be very happy, but if you want it to pull harder longer, then that is where the knowledge comes in to play. I have a couple of different torque control springs that I have used to shape the fueling curve how I wanted it depending on the application.

If he sets the governor up by the book, disregarding the max quantity amount, then he should be fine, and you will be at a standard starting point instead of god knows what settings.

For $1000.00 plus parts I am very tempted to get in the game, but I am very busy now and still do not have an engine for the Dyno.

For M pumps I personally made my plan:

7.5mm Floyd elements, delivery valves and 500 EUR for labour + shipping.
The result is a perfectly running pump with external full load adjustment.
No issues with strange governor behaviour etc.
The shop is PP D from Finland and I can not imagine what can be better on a Mynä pump.

Element+delivery valve is 68 EUR.

A pump with larger elements for me is the basic step into tuning.
From the platform of stock engine with smokeless extra power and better economy you are prepared for everything that might come in future.
Making a compromise with the pump is not worth the bucks you might save.

Ok great news ..... My injection shop here in Northern Ca said he wants to mod the MW pump over the M pump because he said its better to fine tune but the governor is a ***** compared to the M pump governor.


So he is seeing how much he can get the elements for and if its too much he will use the chinese ones we can supply. So at the moment im holding off on the group buy. If his cost is too much then we can all talk about me taking the plunge on ordering a small batch for my self so we know it is safe to do the group buy.


He is going to get back to me with prices and how much time everything will take.

So far it 1k plus elements. I told him others might want more but i want a good 200rwhp. He said not a problem so everyone cross their fingers i should have exact prices next week then after that i will send him my pump and i have the extra cash things should move faster then we have seen else where.


CROSS THOSE FINGERS!

See the thing is i trust that this guy knows what he is doing as they normally mod the IDI older dodge pumps. Now think about it guys....they are modding based on bosch only specs they are doing playing and they are doing different combos on parts and tuning.


Now give them a SIMILAR pump and they should be able to figure it out if they are worth a **** right?
