Hi as we are running 45 mm trottel bodies on an 2l 16v vw engine and feeding methanol will it make an difference if we move the injectors to the front of trottel body so it sprays directly down the trottel body and not on to the skirting or side wall of manifold
If ecu functionality is there and cost isn't a problem, small primary injectors close to the ports and large secondaries above the trumpets will give the best start/idle and peak power combination.
If you are only running a single set of injectors you might find it is more difficult to establish idle/low load running with high mount injectors but it should make a bit more power.
