Harry there is no hard feelings from me mate!
The only thing I find to be offensive is if someone tells me I am wrong and their way is better! especially if they have never experienced their way or even mine!
( None of which you have done or meant!)
But others yes!
I respect people doing different things as then they have stuff to share to make others understand of different possibilities!

There is no problem which can't be over come with any setup! It just takes knowledge, Thinking and finally money!

As for the draw through disadvantage you mentioned ( Re backfire!)
All you need to do is look at the big supercharged engines and copy their burst plate design into your manifold!
I know of an A14 inlet manifold setup like this! ( This one has the plate underneath the manifold ( don't know what this was originally for?) Spring loaded so in the event of a backfire it will blow open! ( Springs are rated to compress around 20 psi of pressure)

As for EFI this is what I am fiddleing with now on my Turbo A15 1000!

Cheers Steve!
