VadimOriginally posted by SweeperMark: I was talking to some of the guys about this dual plenum design today and what they said to me is :
Will try to translate. There was a guy here who was making custom made intake manifold for his line bmw engine. Well in the end manifold was about 20litres
, welded from ss steel. When they tried to start it and get some heavy foot on pedal , then release it , throttle closed and vacum squished the manifold like a golf ball. Welding destroyed and some of the pieces gone in to the engine.
Basicly what I'm trying to say is that , won't it happen on welded manifold like ours ? WOn't vacums just destroy it ? I mean original manifold are made from casted aluminium + on dual chamber manifold space between first and second chanmber is quite small.
Hope you get what I'm trying to say.
must have been a lot of vacuum to make a manifold implode
Well I am trying this IM out on the engine I plan to replace soon, so if it all goes wrong I wont cry too hard

Whats the reason for the process - stress removal at weld joints or what ?
I've missed out lots of history on this thread - what is the rationale for the tapered shape of the plenum ?

To quote Tommy "It brings BALANCED air delivery to all cylinders and no richer/leaner differences between cylinders due to intake manifold structure."Comment

Amongst other things I came across this IM from Pogea Racing, is it any good?:

Aelred can get hold of some dual plenum IM for about £600 which have apparently showed some very good results.
