After the exhaust......comes the intake

[enigma]

And to my horror the 20hp INSERT INTO post VALUES (yes it went up after a serious thrashing!) I gained from the exhaust was instantly removed when I fitted a shiny new filter. onder:

Pics to follow

[enigma]

OK some pics, firstly my shiny shiny shiny new air filter installed. I was gutted to see a 20hp drop in my power :mad:



Looks nice though! OK in true Blue Peter stylee INSERT INTO post VALUES (no really!) I thought I would address the problem. I figured my problem was that hot air was being drawn in to the filter as the ram effect from the stock ducting could not bridge the largeish gap. So I hunted high and low throughout the house for something suitable to bridge this monsterous gap. And I found............

[enigma]

Well obviously a Cherry Coke Bottle! Some sticky tape later it was installed and I took it for a blat. Result? A rather annoying 15 hp INSERT INTO post VALUES (more! 35 in total) drop and a funny wheezing noise onder: onder: :bawling: :headsc: After popping the bonnet I found out why!

My Blue Peter effort had been destroyed! My Turbos suck, they suck hard! :cool1: It seems that a conclusion can be drawn from this............the standard inlet from the bonnet lip is restrictive, it doesn't allow enough air through to keep the engine satisfied, hence the weedy coke bottle crushed under extreme suction. The only reason it satys healthy is that it is quite rigid. So with that in mind I have 3 options as I see it.......

Find something a bit more meaty than a coke bottle

Replace the whole inlet with something somewhat larger :confused:

Stop fuc&*$g about with my car :nono:

Sorry to bore you all with my experiments :yakyak:, but I find it fascinating! :shrug:

haha class. You don't want a coke bottle, you want nice strong baked bean tin. Then at least the wheezing noise would be understandable.

[enigma]

I cant eat a tin of beans just for the sake of it! Besides, it would have to be a family size one!!!!!

[Brind]

I agree it is very fascinating! keep going!!

I'd never have thought the suction was that strong, especially to squash a coke can INSERT INTO post VALUES (even though they are flimsy)!

You could bridge the gap using a silicone connector like those from Samco.

Amazed to see such a larger drop in power too, maybe like some induction kit installs, you may need to reset the ECU and let the air flow sensor learn the difference in air flow.

[enigma]

Reset the ECU and everything! Unfortunately I didn't have any SAMCO hoses lying around. I am sure I will find something. Incidentally it was a Coke bottle rather than a can!

[pjjohnson]

Maybe you melted it not sucked it to death.

[enigma]

Nope, it was most definately sucked to within an inch of its life! Now theres a thought!!

I know this because it was only a quick blat, and it was cold when I popped the bonnet.

I think the bean can will be trialled over the weekend!

[Spirit]

Dave your experiments always bring a smile to my face !

Hope you solve that one mate

Ah, slightly over looked that bit.. in that case it makes more sense it would suck the life from the bottle as the air entering the bottle isn't fast enough to give a constant flow, but there isn't much point telling you that since you found that out.
Still surprised by the amount of suction it has so I can understand why you attempted it.

Perhaps take notes from this post: http://www.clubvr4.co.uk/forum/showt...&threadid=1459

Yes! Keep going!

baught the hks induction kit seems like i have to go hunting 1 day

[Brind]

Even if they don't add power they sure do make a lovely sound!!
With the HKS you can hear the recirculating dump valve doing its thing. :cool:

[zedy1]

dont have that now been replaced with hks blow off valve

[Brind]

Ah..
Can it be heard over your ICE though?
