[poweron355]

hi got myself a vt gts 355 the other day with a 6 speed man and extensive engine work. it came with a dyno of 410 hp at flywheel and 307.5 at wheels.
it has the come inlet manifold dual master timing chain, roller rockers, but i dont know what has rteally been done to the bottom end as i want install a bit of a supercharger. any ideas
is this advisable or not the motor has done 12000 kays since rebuild and has bigger fuel rails and injectors, it does have cam but sure what sort its got a little little lumpyness to it and you just cant beat the sound of it its bloody awesome !! can u do anything to the computer to get more power or are they mader from factory with a performance comp.

HELP HELP HELP my first ever high powered machine

call the engine builder(if it was built at a shop) and ask whats been done.
