I wished you hadn't brought that subject up Simon.
I did a lot of studying on my old 4/4 system when I was tuning the 1800 Zetec and subsequently swapping to the 2 litre Zetec and I came to the conclusion that the Librands Manifold wasn't too bad. Not optimum but tolerable.
Anyway, prompted but your comment, I have been looking at the Roadster manifold.
It's dreadful. The centre primary is only about 6 or 7 inches long and all 3 primaries are different, the longest being about 10 inches.
The collector doesn't look too clever either.
Now I'm not an exhaust manifold specialist by any means but I'd wager a fair bet that there is a lot of extra horsepower to be had "simply" by extending the primaries.
Packaging looks difficult though which is maybe why Librands haven't done one. Hey Ho
