i likewise think it will be a waste, what is the point of causing air swirl before the turbo? with its RPM its going to much up any airswirl caused. what you want is clean, cold free flowing air, this item wont do that. and after the turbo will only cause furtherdisruption due to the fact the oe manifolds are rougher than badgers perverbial. as for the subject of the landrover if you notice they have disconnected the EEGR, this alone will account for the increse in torque.
with diesel the route for power, and keep reliabitlity, tends to be in order airfilter (free flow), Exhaust (again free flow), Intercooler (larger) and then muck with the fuel and boost to match the better flowing engine. after this it gets too expensive, ( change to petrol). :shock:
this has been the route adopted by the army to gain a few extra Nm to its fleet of rovers. bar the ecu chip and with the filter/ exhaust and intercooler with adjusted boost it make a BIG difference, if only they would sort out the armour.. :roll:
