to the best of my knowledge 164rwkw is about the best anyone has got out of a crow549. on a roller dyno anyway. i know of one with a higher sheet but from a hub dyno. its a great combo now but im just greedy

yeah definitely, has a bit more power to be extracted first tho, its pulling a bit of vacuum at high revs and needs better spark and more fuel up high. i pulled 4deg timing out from 5500-7000 as its going lean. new injs will be here shortly, and new plug leads as mine are shagged

injectors are on their way, missus dropped them in the post this morning. as for the ba airbox, I think it can fit with a bit of persuasion on the inner guard with a hammer, or heat up the airbox and bend it so it fits
