A sharp intake of fuel..

[Beej]

Help please...

My 4.5's intake tubes (the wobbly purple pipes that connect from the air box to the head) are looking really bad. The wire reinforcement is popping out, the y are really squashed and misshapen and (although I'm no gas flow engineer) this can't be good. Has anybody any experience or ideas of a sensible and robust alternative in aluminium or carbon fibre or using a plenum chamber or anything? Joolz? Danny? anyone?

The engine is out at the moment (surprise), so I can play about with measurements and stuff.

Magic. Thanks. So, I need to talk to ACT, I guess? Meanwhile, has anyone considered straight pipes up into a single central plenum with a single air inlet pipe to carry the temp sensor? Just a thought, but its how most other cars work. Are the pipes tuned for extra torque or something? If they are, then how they ever work is beyond me.

with a Ferrari 550 air intake at the front?

Oh please! Take one beautiful car and in one fell swoop of the designer's pencil destroy it with a piggy nostril mid bonnet. Why did they do that? Oh yes, they're italian.

PS Haven't actually got hold of ACT yet. I seem to recall that the factory decided against carbon air intakes? why was that?

They kept cracking.

Beej, If you end up replacing your knackered intake trumpets any cance I could have your old ones? I'm looking for an old set to butcher, in order to play around with different tuned lengths.

Danny the ACT carbon ones, are keep cracking? or the ones that the factory tried?

The factory ones I believe. They were tried very early on in the cars development but the idea was dropped. This was cited as one of the reasons that the quoted horesepower figures on the cars was not as high as the pre production examples (if I remember correctly).

Please don't mail me regarding the horsepower figures, I realise that they are all just made up anyway

Grant tuscan.. of course you can, they will be no use to me. However, before everyone gets too excited at the prospect of sexy black intake pipes, Tim has mailed me to say its a winter project, so don't hold your breath. He is being very coy about prices and cracking.

I am talking to some aluminium fabrication people about using ali as an alternative - the shape of the tube is, um.. interesting!
