im hoping with the new set-up im getting together for the 5, it'll be around the same power, and i brought the 276/272 in the kelfords, being as aggresive as they are i kinda shyed away from 280+
keen to learn more about ya compound set-up too, understand the principal just trying to imagine the manifolds/ piping,
it must be an animal to drive too,
and yea how does that work ay rob, i found that also, the pac springs i didnt even look into tho, just brought them off kelford,
