Also is there any benefit in shorting the trumpets on the efi plenuim, as there does'nt seem to be all that much room at the top to actually get a sufficient amount of air in..

Presuming you're talking about a Rover v8 then see this thread:

Any idea how the unequal intake lengths worked on the dyno?

As there are a few engines out there now which are running half and half to better spread the torque curve. But I've not seen any dyno plots for any

No idea if this works at-all on the dyno. I might make another one and get my mate with a griff 500 to test it in comparision to his current ACT carbon trumpets and perhaps his orginal 500 "trumpets"rolleyes

It looks like you would loose a bit of volume in the plenum - which does not seem like a good idea..
