Need some input from a technocrat on this item. No doubt someone will have raised this previously but I can't trace.

Not now, but soon I'm going to investigate the remap options. From what I've read herein, in combination with a remap most of you fit a PD160 intake (some price, aren't they?)

My question is: If the air box end of the PD 160 pipe is the same cross section as the std 130, which I assume it must be, how is it that the volume of air available to the engine increases. Go on, patronise me, I don't mind.

Because the open end on the front panel is larger, more volume of air is induced....I think!

"........I think". You're like me, you're not too sure either.

For instance: supposing the front end was the same X section as the channel tunnel, ultimately the air has to pass through the fixed X section of the air box inlet. This analogy explains my thoughts exactly.

but the area of the air box is greater than the diameter of the pipe (both pd130 and pd160)

So if it doesn't make any difference why did Seat change it ?

Who said is doesn't make any difference?

It's been well debated on here many a time, however £75 for a plastic pipe :eek:

this consists of 2 parts.

A trumpet, and a pipe. The standard trumpet intake hole is about half the size of the PD 160s trumpet, and the bigger pipe fills the gap in the engine niceley.

To be honest, I never noticed a difference even with a Pipercross filter.:confused:

I know its two parts....?!

Im making a Carbon version, after the front splitter is made up...

definatly makes a difference my car just recorded 155bhp and 270 ft lbs on awesome's rollers today with only this mod,25bhp for £20 that works out at 80p per 1bhp;)

Really?

Are you sure thats all its had done?!

Just seems a big gain for not a massive item...if thats the case why didnt Skoda put it on in the first place, and say its a PD130 with 155 bhp?!

the whole pipe is wider, plus the trumpet end is bigger to get more air in to the airbox... helps the engine breath a little bit better, less smoke and a tiny bit more power

don't know but i have owned it from new,and i doubt skoda re mapped it , and i certainly havn't done anything else in that department,it blitzed the other standard fabia's there,but at trax this year they all said it seemed to pull out of the corners much quicker than the other furby's ,and before anyone goes on about optimistic rollers look in the north west meets section at the rolling road day results to see that they were very realistic,hearts were broken today:D

IM not doubting you mate...

Most standard cars put out over 130bhp anyhow.

The standard pipe is restrictive to a degree, so a larger pipe allows for me air even though as correctly pointed out the actual intake of the airbox is unchanged.

Doesnt it force more air into the airbox more quickly or something?

I think that it does cause a bigger (Wider) Venturi at the opening, so it would flow quicker...

The carbon version i will be making, is going to be more of a ram-air version, so in theory (famous last words!) it should get a real good flow.

that remark wasn't directed at you mate:thumbup:there will be some on here who will post that sort of thing,and before today i would have agreed but a standard vrs made about 140 at the fly and 122 at the wheels which is what i was expecting,i can't believe a pd 160 intake has made this much difference,i am well happy tho:D

So, are you saying, just on its own a PD160 air intake trumpet and pipe made that difference to a standard 130 PD vRS? That being so, I won't bother with the cost of remapping, I'll just buy a PD 160. What's the £20 you mention; is a PD 160 available at that price somewhere? Or, am I just not getting the point here?

got the pipe from a member on here second hand,and i wouldn't expect that sort of increase the ones that ran with pd160 intakes and a dragon box were similar to mine,i don't know why it ran so well but here is the dyno sheet

So if it doesn't make any difference why did Seat change it ?

I don't doubt the Seat engineers know exactly what they're about; all I was asking was, could someone herein who understands such things explain why/how it works. I was just interested, that's all.

So, you reckon it's something to do with increased air speed down the pipe. That makes sense; is it factual I wonder?

thought this had been explained,the standard pipe is a lot smaller,so restricts airflow,the pd160 pipe is a lot bigger,therefore allowing more air to enter,the more air you can get in,the more power the car will produce,for example,a turbo is just a compressor which rams more air into the engine,to conclude more air + more fuel = more power.

The pd160 pipe will produce minute results on its own,but when coupled to a few more mods,ie bigger turbo,it becomes an essential mod.

I would advise against a re map untill the brakes,suspesion and a jabba arb are added,but that is just my opinion:thumbup:

I wondered how long it would be before this came up.

I must say a pretty impressive standard power curve will make a very good project base car

:rofl:

Personally I beieve that the increased size of the pipe means that the engine has more air available to use at any time - planting your foot would surely require more air than is immediately available in the airbox, having a larger pipe is like having a larger reserve ?

Whatever the reason, it's made quite a difference to my standard PD100.

Have you got a standard filter or an aftermarket one?

Thats one hell of an increase. Suddenly £70 seems not so expensive - even if it is just a piece if plastic pipe.

BTW did u know the figures before you added the pd160 intake?
