I will be getting a snorkel for my new 300tdi 90
Looking there seem to be a lot around mainly the moulded one piece & the tube metal/plastic with felexible joints
Anyone know which might be better
A few years back for the magazine we did some performance checks on a rolling road, adding a high flow filter, silicon turbo pipes, better exhaust etc etc. The safari type snorkels cut bhp down by around 5bhp, the standard Land Rover metal one about 8bhp if I remember. I've still got the figures somewhere I think.
If you use basic physics and basic common sense then unless the diameter is huge any form of ducting prior to the turbo inlet will cause a restriction , the longer the ducting (i.e snorkel over standard short intake pipe from wing) the greater the restriction, the more bends in the ducting will also have a similar effect , it's not rocket science for gods sake !
