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

Purpose of the snorkel is to raise the intake as high as possible! The best snorkle, one with the less angle for air to get around, is the SOUTHDOWN one. It fits through the top of the wing, so does away with the crappy plastic wing fitting.
The standard Td5 Intercooler has very similar internal dimensions as a standard Tdi intercooler so no benefit in fitting it...buy a decent uprated intercooler, silicone hoses & plumb it in with as much solid pipe as possible.

however the intercooler has a much bigger surface area and is much thinner, so its more efficient at its job ...actually....Jamie :-$ :lol: :lol: hows goin ?
yer big intercoolers make a big difference...on road....but offroad you need make sure something is drawing as much air as possable through it or else its pointless :roll:

Oh Danny boy....you are as usual correct it is more efficient at doing it's job, however...
Fitting a std Td5 intercooler to a Tdi, after you have piped it in around the engine will make [!Expletive Deleted!] all difference....if it did you would have fitted one :twisted:
I'm good...you?

mayby its fixed backwards so when offroad the dust sand or whatever from the motor in front dont get kicked up and go straight in to the snorkel
Xtremeteam:
snorkels make no odds to the performance
tried mine with & without on dyno & lost 1 Bhp with the snorkel fitted

I used to build turbo drag bikes, the thing with turbos is the heat passed from the exhaust gasses spinning the turbo as it acts like a heat exchanger. For every 1 deg you can cool the air after the turbo you gain 1 bhp.
We used Range Rover intercoolers in the beginning and used to get the temp down by 80 deg which would show up on the dyno as a bhp increase of between 75 nad 79 as the dyno was indoors and we could not get enough cool air over it.
That's why we used to put huge intercoolers on the power increase was huge compaired to added weight they were even playing with a water cooled intercooler before funding got with drawn.
