Technical questions

[Malcolm Parker]

I've always believed that a longer inlet manifold is beneficial for torque and low down power but perhaps one of our racing forumists could elaborate.   My Ulster rep has a down-draught SU on a long manifold which puts the carb well above the engine.  Fuel is supplied by an SU electric pump.   The benefits are that it is away from the heat of the exhaust and it is easily accessible for adjustment.
