MG MGF Technical - More pipes 4 K&N better?

I posted this on the general site but I thought you techies might be more knowledgable.

Anyway, With the K&N Induction kit would there be any benefit from adding another 1 or 2 pipes to the already existing 2 pipes to funnel more cold air the the filter?

I mention this as I noticed yesterday one of my pipes had been mangled and effectively squashed closed after too many encounters with speed bumps and those pole thingys that you put up to stop people parking in your place.

Need less to say after reshapping the mangled pipe and opening it up to let air flow towards the filter again there was a noticable difference in motorway acceleration and sound (Vrrommm, vrrommm, roooaaaarr,hooowwwl, sorry).

So, would adding another pipe make any difference?

With regards to K&N's does the position of the pipes in relation to the Filter make much difference. I could find a convenient place to fit the on the firewall (1.8i) so they are about 20cm away and not pointing directly at the filter. Are there any other 1.8i drivers who have found a better place top position the pipes ?

Paul, you are right. Basically the exposed cone filter needs as much cold air as you can throw at it. Whether this is achieved with additional pipes, or better with one bigger tube, then so be it.

Craig, yes the positioning of the cooling tubes is important as I discussed this with K&N R&D. Get the tubes too close, and you get turbulent air flow around the filter. Turbulent air flow is fast moving air that is at lower pressure than still air. Lower pressure air = lower charge density and therefore oxygen entering the engine which means less power.

The bulk head is a reasonable place to put the cooling tubes Craig. I've got a picture of the positioning of the tubes in my car's engine bay that I'll put on line some time next week hopefully.

Thks Rob, Hmmmm......more pipes and bigger (thinking)
Paul

I raised this question before with no good answers.

:)

Seems like I will be adding 2 more pipes then.

This is where Rogers idea should really come into it's own, let's just hope all that air can get out again ;-)
Tony Smith

Looks like I am off to get another pipe then.
