I imagine the tool I make will bolt to the center intake runner so it works on either side intake or exhaust

Here's a simple one I use on 12v B series Cummins engines. Just put it in place for illustration purposes, this engine has already had a session with this tool

To follow that up, didn't you say that the euro spec 535d is the same turbo setup, but with exhaust housing being more centric? So there is more meat on the 535d exhaust housing?

No

Older 535d turbine housing is more centric according to exhaust pipe start position, that is true.
It will complicate the work, but not stop it.
I do not know, how much there is a space for bigger turbine, never measured.
It is just a rumor, that nothing can be done to newer turbo´s.
Bigger turbine do not need so much room and if necessary, metal can also "increase". Method is like painting.

But you are very free to do anything you like, it's not my business in any way.

Ha-ha love this guy!

I'll tell you one thing, I paint better than I can weld !

The result is, in my opinion so good and the feed rate so high that the max power rpm is supposed to be in that position.

I have a table indicating the fuel supply amount in proportion to the engine speed and torq. It is self made, so it is not true, but near it.
641 lb.... is 870nm and ~110mg/stroke
110mg/stroke should give about 405-410hp/4000rpm => so there is some additive used.

Thanks for obliging me.

I probably should have used emoticons previously. It was kind of a regional joke that obviously didn't go over well. My uncles and aunts all grew up in South Boston (you guessed it, Irish). It wasn't until I was in my mid twenties that I found out the names I knew them as were "neighborhood names". Uncle Mikey was actually James. Uncle Jakey was actually Albert ... later, on trips to certain sections of New Jersey, same thing. Everybody has a "e" on the end of their name.

I probably just made things worse by telling that story ... ;-)

Dang.. This place is starting to get a 'birdcage' feeling..

Can you explain what you mean by "so there is some additive used"? Thanks.

Nice! This is off topic, but ... was this the new V8 Cummins used in the Titan pickup? If so, what's your thoughts on the design/build quality?

[tuikku]

.
The true fuel rate can be seen from torq curve, if it is not limited.
And there it is not, result is so good.
870nm torq /2750rpm needs ~110mg/stroke fuel. (table vs torq curve max)
And I know that 400hp/4000rpm needs ~105mg/stroke fuel
So, 110 gives ... excatly 420, I calculated wrong previous time ....

I thought that 110 is not enough, but I was sloppy.


This horrible language takes so my attention, that I am not able to think clearly anything else ...

Shnaggs, I don't know if this is where you are going, but an older turbine housing with mods and a downpipe could be an interesting option. Also, if you don't need the IWG, could "painting" help the situation? Don't know the answer, just thinking out loud.

Yep,

basically what I was thinking. I have no idea what the outcome would be, but if there was more material to play with on the older housing, could be interesting with the more centric exhaust outlet.

And yes, if we "paint" the IWG, that could open up the possibility to enhance the flow passage out into the downpipe, plus using the EWG should just be icing on the cake!

Now who here is our Michelangelo???

I was having a discussion earlier about EWG from manifold like tdiwyse and a downpipe plumbed for the EWG.. I've been told I'm pretty good at "painting"

Edit: I don't feel "painting" on the turbo is the best option.. I imagine more of a fixed rod that bolts to oem diaphragm bracket and wastegate lever.. A 'deadman' if you will..

You're welcome, the best thing is that it seems that he still have the small HP pump (R70), great news with that power (around 460 crank hp)

Is the second link supposed to be the same? Maybe this one https://translate.googleusercontent....TRw-9CwFNTbPAw

I think you are right.
For that matter, maybe even a threaded plug, staked on the threads.

Something went bad... Post now edited with the good link
