hi all,

purchased a D5 from a friend a week ago,... ran it in (quick method,... 1 tank heat cycle, cool-down 2 tanks idle, , 2 moving rich tune, 2 moving half-tune, race tune, got stuck once after the cool down,...) the engine ran great compared to my OS 12TR(PT) in a small margin, but not when compared to a Nova S5. The things I suspected was, first, the carb setting,.. and second the pipe (I used the same pipe and manifold like when I use my TR(P)T, and was aimed to get mid-top end power), the problem is,.. that the engine has quite a weak top end (although has a smashin mid-range bang...) the question is, since I tend to blame it on the exhaust,... how long a pipe and manifold will suit a D5 best on a small-medium track (up to 30 mtrs main straight with a twin 120 deg S-curve entrance and medium hairpin at the exit),... and just to verify,... I'd like to know the possible optimum setting for that kind of straight and exit from you guys. (preparing to win next weekend's race with a STS )

thx in advance
