front turbo induction pipe

[sean_goodman]

having recently replaced all by water hoses and induction pipes for samco i must say i dont really like the flexi induction pipe to the front turbo.

i guess i have two options...

1) replace with a hard pipe and couple it up with a couple of samco joiners
2) move the air filter for the front turbo forward to the fire wall where it used to be located.

which is more preferable?

the relocation would be easier i think as all i would need to make is a bracket.

this would give one filter forwards and one staying rear in the intercooler box

any advice or thoughts would be great

cheers

Talk to Wayne at Proalloy, they do a hard pipe, but you will need to buy the header tank as well to make space for it.

if i went hard pipe i would make one myself to suit.

`header tank i thought you mentioned to me last week you had a spare one you just needed to try and find it, or am i confusing you for someone else mate?

Out of interest, why not?

i recently, changed all my water hoses to blue samco as a few of the crappy rubber ones had perished.

that meant the engine bay was sort of half black (induction) and half blue samco(water).

been doing a few jobs lately, namely adding a set of defi oil press, temp and water temp, with defi display mounted as owen did his. also changed all the turbo oil hoses to shiney braided returns and bradied feeds in silver heat sheathing.

engine bay started to look quite nicely dressed so i opted to change the induction hoses to match the water and polish the hard pipes.

the only one left is the ribbed pipe from the intercooler box to the front turbo. firstly i dont think it fits in asthetically with the silicon plus i am not completely convinced about airflow down a ribbed pipe and the difference in tube lenghts when comparing front and rear turbos.

asthetics to one side, surely it is best if each run is the same length and down a smooth pipe. this, if true would mean surely the filter for the front turbo is better off moving forward?

i am quite surprised moving the filter hasnt been discussed more often, i did try the search button but didnt dig up much

Here's a thread I started in the U.S.

I'm very happy with the results (and the general clean-up of the engine bay that goes along with the change). But in the U.S. that filter is now just inches from the driver's left ear so you have to like those intake sounds if you do this .

As for ribbed pipe vs. smooth--I'd be very surprised if that change has any measurable effect on performance. The air in that pipe is at atmospheric pressure and is not moving all that fast--I suspect the temp of the inlet charge is more important to performance.

thats great thanks mate, i assume you have a mounting bracket which fixes to the diaganol frame section under the filter?

any other thoughts guys?

Iv'e discussed this several times as keeping the inlet lengths equall is common sense, just never got around to trying it.

With regard to the curly hose, on the dyno, in back to back test going from ribbed to smooth made 20bhp with no other changes. I dont know if it would make such a difference on lower powered engines but it must make some, it may be that i have found its flow limit.

Looks like a fairly easy job to do with fairly good benefits IF you change the ribbed pipe also then. And get some added noises..

think i will be making a bracket tomorrow lol

Sean if you want me to send you some templates let me know.

thanks mate, actually made a card template yesturday afternoon. will make the bracket out of a piese off ally sheet today.

will have to order the samco hoses to join up to the turbo but in the meantime will probably do a connection with a short piece of ribbed pipe

thanks for the offer though

Now that was a suprise! I'm having trouble getting my head around that...most complete induction kits won't give that (admittedly on low bhp cars)

True though, Trev's got the numbers somewhere, just shows how bad that black curly stuff is.

Well, in my addled brain anyway, the natural progression from this would be some sort of ram-air system...free horsepower!

Adrian I take it you will be posting your back to back results???

You already got two of them, one on each side of the engine...

Presumably the 'new' position with the filter sat right in from of the intercooler can only use up some of the air that the intercooler could do with.
