does fitting a larger intercooler to a 300tdi defender really work.

Same number or air/fuel molecules going in per given volume = same power out, all things being equal.

The pressure at the inlet manifold/plenum is regulated by the waste gate actuator, so airbox pressure really can't make any difference, besides, we did an experiment to prove that "ram air" is bunk which it is.

im not an expert on tuning diesel engines but have had plenty of experience with 400bhp sierra cosworths!!!
the air filter dosent really matter on a turbo engine running small amounts of boost so long as it isnt a little blocked up effort!!!
for more power you just turn up the fuelling on the injector pump and wind in your actuator rod, more boost +fuel=bhp
the intercooler will help as the denser (cooler) the air charge the more power
a diesel engine dosent run a great deal of boost because of the lower compression engine .
i havent messed with my one yet ,,maybe when it gets a bit warmer!!!!!!!!!!
marky:
Does anyone know if the standard intercooler from a late Td5 is any better than that on the 300Tdi? Just that one of works' rovers just got the full chip and intercooler upgrade (over 200BHP now :shock:) and the original is now going spare :twisted:

I'd interested in finding out about that too, and is it an easy fit?
Suvvey:
Got a chance to compare the 2 today and the Td5's is a good 50% larger but is also mounted differently so reckon the plumbing may be an issue and I'm not sure about clearance on the rad either. :roll:
Saffy:
I the so called air ram effect of a snorkel has any relevance in the real world then why did landrover have the G4 rangie's fitted with fixed rear facing snorkel necks?
