Replica Cast RS2 EMs: Good or Bad?

[AndyP]

Hi,

if you send me a small piece i maybe able to find someone to check it out for us and see what material it is.

I already looked into that as we use testing labs at work, but the size of sample they needed would mean trashing the manifold so I passed on that.

This guy i knoww said thy only need a very small piece and with phasmatoscopy they see the % of every metal in the casting.

Dont know...

How can one see on a EM that it is no good, take this as an example:

Are there any obvious signs of crap flowing etc just by looking at the pictures?

I would like to learn more about replicas and what too look out for, and I know that "nothing beats" original, it's more of an educational interest.

I think that just looking at the price gets all the warning bells ringing in my head.

Thats a log manifold where the cylinders are joined by T-Pieces and not a collector.

Not my thing at all.

Do you mean a EM like this one?


Tubular style

No, thats a proper tubular manifold made by Wagner.

I'm talking about the one you posted in your link.

Sorry, I think I was a bit unclear:

I meant to say (when posting the picture):

Is this the kind of EM's you like?
Or is it some other form (the last one was a log?) of a EM that you prefer?

[Jamo]

Yeh that EM is fine all the runners collect at the flange therefore dont the exhaust gas pulses dont interfer with each other in comparison to the log manny

[k.alle]

Ok, good we made that clear.

But I have heard figures about 500HP before changing ex.manifold on those replicas, or is it a I-wish-it-was-true statement?

The log ones are a lot more MOT friendly (at least in sweden).
