Last year I was quoted about 1600 USD + Shipping for Myna to do a M pump with custom ALDA.

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?

Be Careful about the Quote!!!

I want to know what you are getting for a 1K in Labor only. This seems high. I had my pump rebuilt for my Dodge and it was only 450 in labor it was the parts that got expensive. Can you ask him why so much? Tear down should not be more than 2hrs rebuild max 4 hrs and bench test/dyno 2 more hours, were talking 8hrs. This is unless he is going to mic every piece and then you find alot more time envolved and alot more in parts required. These pumps are not new so they will be worn...its a fact of life!
Be careful about this quote he should have a high and a low quote for you for the labor. His quote sounds more like it would be in the middle, if he did not give you a low quote you will pay what he has actually quoted you and wont bother to tell you it didnt take that much time.

I've got a shop here in SF (south florida) that will "rebuild" a M or MW pump with what ever elements you supply and make it idle smoothly and put out the power the elements give via increased fuel output. Cost is about a grand, plus the parts you supply. I said this over at STD and got few interested parties- GSXR IIRC said it was overpriced. I already have a Myna pump on my car with a undersized (stock) turbo- so I don't need the service right now, but I've dealt with them in the past in search of greater power- plus SF is the home of monster diesels in yachts and sportfish boats- so they know IP and power.

Myna Quote

I am interested in upgrading my IP, and I contacted MYNA. I got a quote which looks lower than what you got. Not sure if the value of the EURO or USD has anything to do with the new, lower price. The only problem is getting a core pump and the costs of sending it overseas, and then paying for shipping to get it back. This is what they had to say a few weeks ago.

"As the M pump is originally from NA engine it does not have LDA. Custom
made LDA costs 200€. The LDA basicly limits the fuel delivery in
function of boost pressure and thus prevents black smoke before the
boost pressure rises.
So the total cost for the M pump rebuild would be 1050-1100€.
Shipping is around 120€."

Address is:

I have been reading through several threads both on this forum and on Superturbodiesel. I am not getting the answers i am looking for from either place. It doesn't seem that there is a quality job that can be done for less than what MYNA is asking. Even a few people have questioned MYNA's ability to provide a pump that is properly done. There is one thread on STD where a gentleman has put a supercharger and large turbo on a w126. The project is amazing! A work of art really. He sent his pump to someone back east who built a proper pump with 7mm elements as i recall. But the guy took forever to do the pump and has apparently fallen off the planet. I would be nice to get some straight answers about this topic rather than all of this back and fourth of who is right and wrong. I say use your guy and let us know what the results are. If they are great and cheaper than MYNA I am game. As for now MYNA is too expensive. My car is stuck at stock hp until further notice.

basically the calculation for the 7.5mm elements is:

60 EUR/element + 8 EUR/delivery valve

I personally got a perfect pump within almost shipping time (< 3 days in the shop) and additionally 500 EUR from PP D in Finland, including external adjustment possibility.
This was a 6 cyl. M-turbo pump.

The result is a plug and run IP without any idle or whatever issues that gives good power (not dynod yet) without smoke and without turbo lag.
The rest of the engine is still stock.
Economy is better by approx. 20% even when using the extra power.

What about MW pump from a 617? Seems like it would be hard to find an M pump in the states ... dont see many NA 617's floating around anymore.

I also made MW elements with 6.5mm.
But MWs are rare over here and the number of people asking for MW was poor.
On top the MW elements are made of used 5.5mm with a new plunger and matched into the cylinder.
Way more machine hours resulted in 75 EUR/element.
The last set I sold in November but the buyer gave it back as his shop told him that the elements were used...
If you want big MW elements follow he 10mm threat or contact OM616 member.
