What 6 branch?

[Jhonno]

That wasn't the DS one was it Peter?

We all know the Racing dynamics is the best sounding 6 branch. Its just the best, you can see the influence it had on the BTB. Desgined to work with a cam of around 280 degrees for the best result

Yes it does sound and look the bollox but is it the best in terms of power gains?

No body will ever know!

Any biases or inaccuracies in the Wiki are purely my fault, but are based on posts sourced from nearly six years of Zone posts. The overwhelming OPINION in that time was that the RD manifold was the dog's boll*cks.

However, BTB in that time have made significant and documented gains with their RD-based manifolds, and are the only manifold with a proven bhp increase.

The article should be updated, thanks for the info lads.

and are the only manifold with a proven bhp increase.

Proven in the sense that a dyno chart has been submitted.

There is now a chance this argument can be laid to rest after all, I now have in my possession a fabled RD Manifold and a BTB2.

Unfortuneatley I've sold mt 325i Touring to meatballs so don't have anything I can run both on back to back. But if anyone wants to do back to back runs, even if it's just standard vs RD I'll bring the manifold along.

Where did you snaffle that from then, you cunning fox?

Snaffled from the forsale section on here!
