Turbo back pressure
Maybe one for Mark Shead but can anyone explain in simple terms about turbo back pressure.
a few people have commented that my 7064 Borg Warner may not be big enough for my stroker yb and that if too small it will have too much back pressure at higher revs / power. Where does this back pressure come from, surely the turbo is sucking new air through the inlet side, if the engine is sucking more air than the pressure side can produce where is the back pressure?
‘’What am I missing?
is it just pressure post turbo in the exhaust manifold where the gasses cannot leave the cylinders quickly enough as well as normal exhaust post engine back pressure
