Totally agree on the pistons though, bad mapping was the problem with all the melted ones around the 300bhp mark IMHO
No, Cossie box's die after 400 bhp, no matter the condition, thay dont even need to be launched, as its 3rd gear that brakes.
SECS was running a standard box on 450bhp or so i believe, and it used to last quite a while between changes.
I agree on 3rd gear though, definately the weak point, but at least you almost never hear of a cossie actually blowing the gearbox casing itself to bits like you do with the pulsars!
They are both fundamentally far too weak to be considered reliable for big power, wether a couple of people manage ok with them or not doesnt change the fact they are a common point of failure in both cases.
