Hi
I have a locally made (ie not very good) snorkle on my 200 tdi Defender. It uses the hole in the wing top, rather than the side, and a long section of hose.
I was thinking of connecting it back up, which got me onto looking at the whole air intake system, and how ruddy awful it is.
As standard, air gets sucked in through a tortuous mess of pipes, then:
1. The air cleaner
This rests against the top coolant hose on my car, heating up the air... and is right behind the intercooler, directly in line with the hot airflow.
2. The turbo
Again, heating up the air, but unavoidably
3. The turbo - intercooler pipe - again, touching the top hose, so heating it up again...
4. The Intercooler - finally bring the temperature down a little (and dumping a fair proportion onto the air cleaner casing), before making it's way back into the inlet manifold.
This strikes me as daft. Turbo charged engines like cold intake air, hence the intercooler.
Virtually all of the intake plumbing is right next to the coolant pipes, and must be suffering from heat soak.
There must surely be a better way?
My car has an electric radiator fan, so I have lots of space behind the rad.
There's loads of space on the other side of the engine, too, above the injector pump.
I've been thinking about full width intercoolers, chargecoolers, moving the intake and replumbing things, but someone cleverer than me must have been there before.
Any ideas?
Also, is a cold air ram intake, either off the snorkle or from behind the grille, beneficial to a turbo charged engine?
