Tim, you are a naughty boy !! Fancy anyone encouraging people to soup things up after passing the emissions tests ! Whilst you might appear to be encouraging it, I am sure that you never actually do it youself - NOT !!!
Decisions, decisions - 8-stack or s/c ? From what I gather, the s/c might be the way to go ? That unit in your pic is a really compact job (just needs 2 more cyls) & should fit in ok.
Now all we need is for a s/c manufacturer to come up with that sort of compact unit, drawing air from 8 x TBs on top, and everyone will be happy !
Kind Regards,
Peter D.
