MG MGB Technical - Maniflow HS manifold-MGB

I'm just about ready to drop the 2.5 yards for a Maniflow on the 77 285/60 over/PB FRBV/ 1-3/4/123 dizzy/Peco mgb roadster for that 3-5 guaranteed RWHP promised. Any personal testimonies out there? Vic

Vic-
I have a Maniflow intake manifold on the A series engine of my 1972 midget, plus I had one one my previous B Series engine in the MGB, so I can comment from experience that you'll like what the it does for your engine. Much smoother throttle response and smoother running in general. Of course, just to make things better, a bit more power, too. On a bone-stock B Series engine you should see an immediate 3 HP gain, but with a simple switch to big K&N aircleaners you should have a 5 HP gain. Start modifying the breathing with portwork and a stronger cam and the Maniflow intake manifold will then really show the deficiencies in the Original Equipment design intake manifold. Why anybody would handicap his breathed-on engine by staying with an Original Equipment intake manifold is beyond me! Sheer ignorance, I guess.......

Not so much ignorance as to not knowing where to obtain one from.
Anybody know who sells this type of manifold for an MGB in the UK?

Charles,

try Maniflow in Salisbury - they're very helpful, I got a Stage Two exhaust manifold from them.
