ahhhh ok, i see, so high flowing a turbo means increasing the waste gate size?

when he rebuilt the turbo he said he high flowed it (my brother picked it up so i didnt get to ask about it)

boost will build at high revs.. so maybe the wastegate is too small

i found out the turbos are in fact the same as charade ones, being from a 1000cc motor, you would think 2 would be fine on a 1.5

being a mech eng doesnt help... sure i could calculate a whole bunch of crap but what i have learnt has been from posting here and working on cars, theres plenty of mech eng's that couldnt tell you how a motor works at all
