It's all apiece of piss and the only thing that gets in the way is lack of dosh, if you have the money you can make it go like **** . With a vnt 15 from the likes of the ALH and some bigger nozzles and tune you're looking at around 150bhp, with a vnt 17 of some sort you're closer to 170 which I think is probably about the limit of the AHU internals. Still a respectable amount of poke though. Good place for more info
