GVI process on BMW 318 tds

before modifying again, roll 1 tank or 2, after you draw a real conclusion, and see your water consumption, for info between 75cl and 1l / 100km after all the positive prototypes

Ok, go fill up or 2 and see how it goes ...

Thanks again..

FYI, I have photos of my montage but I still don't know where to put them ....

So put them in your next message.
Click on add an image, download them and don't forget to make a pasted copy of the link that will be provided to you.

Here are some news for you.

For the moment everything is going well, this weekend, I have to go to Luxembourg so, I will see how much I make on average by typing at 120 on the highway ...

I'll try to copy my photos, we'll see ...

Magic works ...

Okay, so you saw how I installed my reactor.

So, to your reactions ......

See you soon

Hello
Big work on the collector.
Your first photo does not leave me indifferent
The plug with the thin rod connected to the reactor rod reminds me of something. Not true André ??
The idea of ​​putting the reactor in the collector I would not have dared.
It seems like a very good idea.
Have you made sure that it does not obscure the exhaust lights?
Cast iron is not easy to work with, what did you weld it with?

Hello,
the idea of ​​putting the reactor before the turbo is good it allows to capture more heat (although badly distributed at each hole of the cylinders) but well positioned in the passage before the turbo is at its maximum ..
I used a similar principle on a large engine
it would have been easier to drill a round hole at each end of the manifold and thread the reactor (less welding)

For the stopper rod, this is the principle I have used since the beginning of my assemblies.
The rod to finish it in point it is not necessary, I finish them square even concave. ((
the entry of auxiliary area did not need to be as big, a simple hole of a few millimeters is enough in the conduit, it can be located well before the reactor.
As far as heat is concerned, the assembly will be efficient
it remains to learn how to dose water and to have good suction in front of the turbo, it must circulate in the reactor especially if it heats up strongly.
Measure your water consumption well and observe the changes in the pipe and get lost in Luxembourg (Mondorf)

to weld it no problem at the arc, I did on a buggy engine r20 2l, it never moved, there are some fonts that weld better than others

to answer the question how to weld a collector
if it is not too old it is not a problem the electrode or the most important wire is to preheat the part uniformly make chamfers weld small portions 3cm to 4 cm and check with a welder's hammer to avoid constraints otherwise your cast iron will crack and possibly aim at a rigid plate on the flat surface of the collector to avoid deformations if the welds are long as on the bmw

hi André,

As for the idea of ​​centering with the cap, you swear it's not copying, I thought about how to center it well and know how to get it out easily .....

Otherwise, with regard to the collector, I did not think of making lights on each side and sliding the assembly there, but if I had done it, that would have caused me 2 problems:

- the length of the tube (here it is already 23cm + the elbows) and I should have gone up to 35 of course

- I did not have a TIG on site to weld the stainless steel of the tube with the steel of the elbows.

I did not dare to enlarge the size of the exhaust manifold because I read (I think it was zac who had marked this) that it had lost more to increase the volume but, it is true that it seems to me to feel a little brake but it can be an impression because it always pulls as well, especially at high speed, at low speed, it looks like it has a little harder, when I am below 2500trs than the turbo does not engage.
Regarding the welding on the collector, I tried it before cutting it and it welded well so I welded everything with the semi automatic.

As for the consumption of water, how to give it more seen than with the constant level and the GV, it pumps only what vaporizes as water? explain to me because i stuck the ...

See you soon
