stage 2+ cone filters and maf

[Jonny81191]

It also has a ram air system which means that even though it's not a cool looking cone filter,

Couldn't care less what it looks like, All I can go on is how the engine feels to drive, and at the moment the cone feels like it flows more.


I'd say the biggest single cost to a HDi intake is the gauss on the MAF (not really needed if you are happy to run a perfectly good paper filter imo), and that weird bendy flexy pipe just after the MAF which probably causes a lot of turbulent flow too.

I assume you've ran tests on the flow effect of the gauze? How much of a restriction did it impose? I'd have thought it wasn't that much on an issue, Peugeot wouldn't have fitted it otherwise...

And the turbulence from the flexi pipe probably makes no difference, as it'll have been designed with optimum flow in mind. A 90 BHP engine only needs as much air as a 150-200 BHP engine, does it not?

Sorry mate but I feel you're making a lot of noise about the air intake system, with no proof that it's good for big flow. As we have (at the moment) nothing to go by, all we can do is fit what we KNOW will flow enough air (big cone and large diameter piping), then go and see if it makes power. I'll try the options out on a dyno at some point, and if the results show I'm wrong, I'll happily eat my words. But for the sake of a few quid, I'd rather run what I think will work for now.

Peace.
