Hi im thinking about making a nice manifold for my 1100 race motor I have a 40mm weber on it at the moment with a warneford medium length manifold I haven’t really done much testing with this manifold and im sure it will work fine but I have the time to mess around and make a new one and compare them. I have heaps of room with a big weber box so im not fussed about space. Im just wondering what people’s thoughts are on the diameter of pipes and lengths etc. I am after a bit more torque rather than hp.
Cheers Jack

Hey kiddo

I have a 6" one here you can borrow to compare.

I always ran a 6" on mine, how ever im told the shorter ones, like the one you have work better on the small bores, it also depends on what ram tubes you use, so the over all length not just the manifold.

Keep us posted on your findings!
