Gday all
I am currently supercharging a 1000cc 4 cylinder motorcycle of mine, i am up to the stage of designing the plenum chamber, as usual there are heaps of designs yet not much in the way of actuall theory and mathematics on how these people came up with them.
Who knows if all they did was wack a box together of aluminium sheeting and bolt it onto an engine.
So if anyone has an idea please let me know
for instance
1) is there a ratio of plenum volume to engine volume
2) what is the best sized inlet diameter
3) should the inlet be on the side? (in which case i am in trouble as i have an engine frame in the way) or is underneath the centre 2 outlets fine?
4) should the box be tapered or does a rectangular box do the job just as well
any advice or opinions would be much appreciated
cheers
Phillip
