Guys,

I have came accross a huge problem.

After I have finished a 6 runner manifold for an BMW M3 my client came and told me that he wants to mount an 60 mm wastegate.

But there's some problems:
-there's no space to make the exit from the collector with an 60 mm due to the elbow will touch the turbo housing
-the collector is too short to mount an 60 mm elbow
-the oil return pipe can't be mounted safely away from big heat
-the hot intercooler pipe is almost imposible to mount with an 60 mm pipe.

Therefore I have made an 48 mm elbow with an reducer from 48 to 60 mm....like in the photo.

Is this OK???

 

Also please note that the interior Diam is 53 mm


I really don't think that a 48 mm elbow will make a big difference!

But please advise!!!!!

 

No ONE?????????? (((((((

 

try posting in forced induction

 

You might have issues with that... Post a pic of the manifold and how you intend on mounting that pipe. What turbo is your customer planning to run?

 

Can you mount the wastegate directly from the turbo housing ?

 

ill advised, which is why none of the bigg(er) turbo's are internaly gated anymore...

 

Can you post a picture of the manifold?

 

yes, pictures of the proposed setup would be best

 

Nothing wrong with it and it controls boost fine.

Even if you get it all mounted up well, what is the point of running a 60mm gate, when the inlet the the elbow is only 48mm? It will still flow closer to a 44mm than a 60. I think your idea will work. I would just stick with a 44mm gate. From the customer end, I would rather be told my plan wont work as well as I think, then pay someone to "do what I want". Just me maybe.

 

nothing wrong with running a gate off the turbine housing. if you have room for it, thats the way i'd do it.
