g'day Tag,
i'm running a Go 5 port/2072 pipe on C2 Amain Blue Dot 25%
i use a 6.5mm restrictor with approx 60% throttle which was set to what was needed to comfortably clear all jumps as well as a good top end on the straights.
i also use 10%-15% EXP on throttle and a 3 shoe clutch with 2x 1.0mm 1x 1.1mm springs.
this setup up gives me 12+ min run times in my rc8t and temping average= 205fhr (95'C) and max 230fhr (110'C) so i have a fair bit of room to lean on it more if i felt it needed.
Mike
