If by a standard box, you mean a fully rebuilt one done properly, as opposed to some high milage snotter then i agree with you with all your comments, other than that if you talk about a fully rebuilt cossie box i dont believe they are really any worse than the pulsar ones, both are on "borrowed time" when you get to 400bhp+ IMHO
Totally agree on the pistons though, bad mapping was the problem with all the melted ones around the 300bhp mark IMHO

The weakest part of the gearbox is the Alloy selector forks, which brake if forced into gear.
Markturbo and Creedy on here are both friends of mine who live quite local to me, neither has over 300bhp, Mark is on his 4th gearbox now and creedy on his 3rd IIRC, thats in only about 30,000 miles or so between them, Mark drives hard but doesnt launch it a lot and creedy drives like a girl (no offence mate
) so i really dont agree with you on that.
Its true about the selector forks, but thats not the breakages they have been having mainly, its been bearing failure in the main im pretty sure.
I do agree though that the selector forks are more about how its driven than how much power its making.
and again the pistons are good for 500 bhp if mapped correctly, but safe at 400 bhp.
Indeed, so like i said, not as strong as cosworth ones which will make 500bhp quite happily with a bit of machining to sort the CR and are safe at 600bhp potentially
Using 2nd hand gearboxes is just the luck of the draw, as they might of done 200k miles, with out services, and alot of abuse before being sold on.
i know of a few low low 11 second road trimmed pulser's, to name one is Lou Rob, with 550ish bhp, doing 11.1 @ 130 at TOTB 2005 and the pod, with even rumours of a baby site still fitted. on a std box.
and i think there's even a late 10 second on on std box in scotland somewhere.
As for the pistons, Yes Std yb's are up for 100+ bhp more, but i weren't meaning that, i used to hear that std pulser pistons are only good for 330 bhp, which has been proven different, and the 10second car also uses std pistons.
