[Diy_efi] Inlet trumpet design

[Hugh Keir]

Hi Dave,

Thanks for the reply, I have 6 * 50mm ID throttle bodies about 6" from the
combustion chamber and 5" from the mouth of the trumpet, with a possible
trumpet length .of around 3".

I am running 30 psi boost and have about 800 BHP from an inline 6, 3 litre
engine.

Thanks

Hugh
