I'm convinced that there is more usable power to come from my 674 for Donington, without resorting to headwork or anything illegal. Things like manifold matching and a change of exhaust should help both bottom end response and top end power.

Ali, IMHO your FCR41s are way too big - even my 39s are excessive given the current valve sizes (but may be useful on a 620 motor...)

Also ignition and cam timing can make a difference, but now I'm giving too much away


41s are definitely too big, as we've discussed before, but I also tried the DP transducers with a different ignition curve. No noticeable difference....

Your 39s are also too big, but not by much. The real issue is the lack of a base setup to work from.
