whats the best for 450 bhp and wahts the real diffrence between them

No difference between the two, just different names for different countries, tends to be Americans that call them BOVs, and english dump valves, no difference between them. Although you can get different styles that dump at different pressures. As for one for 450bhp, i have no idea whats the best hopefully someone else will come along and answer that part for you.
