Is it around 350bhp as per UK cars ??

 

Dont think there is any HARDSET limit IMO, as ultimately it depends on how YOU treat it. I have been running 340ish on myine now for 8 months, 18000 miles, including a couple of drag days.

So far it is ok.

However, i believe at 350, any bad gear change or ill controlled start and you should be crossing your fingers IMO.

All IMO though
