Exhaust Manifold

[Ruffiano]

these are still available:



contact hankiroz@yahoo.com (no relation to me), i'm not selling them but can put you in contact if you wanted.

one of the welds has a hole in it (inside the tubular). Loving the engineering and design though!

[JP]

Looking at it the welds on the inside are for finish and structure not for sealing. So that pin prick is not the be all end all on that merge point. Well spotted though

I saw this personally

Or you could use this one made in the UK:

who makes these?

The one in G60rallye post is made by Nortech

I have 1 critism of it is that the wastegate is at the wrong angle for optimum flow.

It should face forward not backwards to exhaust flow

Otherwise it's effin top notch!

[Thuppu]

There is not too much space to angle the wastegate outlet for optimal flow. Almost all manifolds has it like that, ~90 degree angle to the turbo flange, and they seems to work great.

Awesome looking manifold!

[JP]

Wastegate take of wants to either be at 90 degrees to the flow or aiming slightly against the flow. Otherwise the exhaust flow on high boost will blow the wastegate open causing unstable boost control on a large diameter wastegate. Not as much an issue on small diameter ones that are internal to turbo's so there you gain in having it follow the stream of flow.

[Jamo]

Look again it's not 90 degree angle it's less more like 70-75
I don't agree with they should be angle line that JP if you have upper chamber control on the wg it should open

[Thuppu]

Compared to the turbo flange it is close to 90 degrees.

[G60Rallye]

It is at 90 degrees to the turbo flange yes, like the manifold at the top of the page and from the pictures about the same as Repo's. Nortech will make them anyway you want so its not an issue.
