Thread: Bundalene's Puma project

Slunnie, Erich's already stripped down a few Td5's and I don't believe he found this before. Was it something that went in late in the Td5 Defender and carried over to the Puma perhaps??

You're explanation is reasonable and may well explain why the air filter stays so clean.

I cant see how that can work very well, those blades look as tho they would be stationary, and the distance to the filter housing is not far..

I think that would be more of a restriction than anything else...

But I have been wrong before..

I will see if mine has 1 and might remove it to see if there's any noticeable difference..


Cheers Ean

You are right Simon, the TD5 Disco does have this and the V8 D2 doesn't. Also the TD5 Disco has a duck bill valve and the V8 Disco doesnt have one.


Does this mean that the V8 air filters get clogged more than the TD5?

Memory lapse on my part some D2's are the same, not the sort of thing one looks at often.

So when you take it out Erich let me know how the engine performs without it.

Diesel 4x4s often have a higher spec filter assembly than equivalent petrol models.

Given the age of Td5s/pumas, the intake should have been designed using CFD, so should be reasonably optimised.

Probably not a good idea to remove it if driving anywhere dusty.

CFD ?

Computational fluid dynamics

From Wikipedia, the free encyclopedia



Computational fluid dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the millions of calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. Even with high-speed supercomputers only approximate solutions can be achieved in many cases. Ongoing research, however, may yield software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is often performed using a wind tunnel with the final validation coming in flight tests.

im 99% sure that all deff td5s pumas have that in the air box,

also you say the starter is easy to get out, iv done about 6 starts on pumas and td5s are way way easyer,, like you say heaps of hoses and the body is very close to the stater, thank god for ratchet spanners,
