turbo pipes?

[hbkuk1]

hi all

has anyone tryed changing the turbo inlet pipes the ones from the maf to the turbos? they seem (the front one anyway) fairly restrictive has anyone played arount with them and got any results?

the rear has a short pipe going in but a longer run going to inter cooler the front a longer restrictive run but shorter run to intercooler. i was thinking of having 2 better pipes same length from maf to turbos any thoughts?

Sorry for offtopic but is that 340hp and 320lb/ft with meth cooling or without?

Without. Dyno was done 3 months before meth fitting. Since then, I did quite a few changes, and still gonna do more, then gonna dyno again. At the moment I have maps all over the place so it's not performing at his best. Upcoming holidays drain my funds now (Alps passes in Swiss in plans)

Do you have a pic of that front restrictive pipe you mentioned? I think I know the one you mean, I changed mine and my bum dyno reckoned it made a difference lol.

yep thats the one

Ah yes, thats the ugly, awkwardly shaped pipe I was thinking of. Is it shaped to fit around auto boxes and the airbox?

[scott.mohekey]

Yeah, pretty much. If you have an auto box there is almost no room around that pipe. Getting it out is almost impossible without removing a heap of other stuff first.

[wintertidenz]

It's designed to go around the ATF filter too. You have to remove the filter to get the pipe out.

Are the manual ones different ? or do they all have the squashed bit.

the same, that does explain why its like it....could have made a better one for the manual tho

[elnevio]

Are the later FL ones the same as well? As the gearboxes don't have an external filter.

[CANDEE]

Yes the pipes are the same for all the cars Nev. Having seen the PROS pipes you can see how hard it is to make a replacement.

Im considering running two pipes from the back of a relocated maf..

[wintertidenz]

When I did my hard pipe kit I was going to replace that piping as well, but it's not easy finding someone that's willing to weld a 4" to 2x 2" Y pipe.

This is how I did it. I changed that 'ugly pipe' that goes to the front turbo as the diameter and shape changes along its length and cant be that great for airflow, I didn't think it necessary to replace the Y shaped pipes as I felt they were big enough and there wouldn't be much advantage in changing them.

Here is the unpolished 'ugly pipe' replacement

Which I decided to paint to match my other pipes

And this is what it looks like installed

Ah that's fantastic. Do you have one for the rear turbo? What's the measurement of this pipe? Looks to me I can just buy the s/s piece ad have them mig welded here and join. Including the reducers. This is nice. What does it look like post MAF?
