DIY Inlet Manifold

[Jimmyd]

The plan is to weld a circular mouth to the existing branches and then create a smooth internal flow to reduce the turbulance. By that stage the carb should be sitting very close to the new mouth with very little rubber between so I don't think it'll be a problem.

An idea, I think Shorttrack do a laser cut plate to the dimensions of the gasket for the engine,make the ports and gasket match the head and fit some steel tube to the plate that suits your carbs that way the fuel goes straight in and no bends and they will be equal in length the HP gain may be little but every little helps as I hope this post does.

Good luck.

For refrence,
40mm ID tube make an almost perfect match for the zetec head if the shorttrack manifold plate is used!
