ive also heard of issues with the buschur & ets intakes. the maf has to be scaled to work correctly and ive heard a lot of shops have trouble getting it done correctly.

 

I'm not talking about the box, just the piping.

 

Found a thread with some results on that:

+9whp/-4wtq from switching the stock rubber pipe to an aluminum pipe

 

There is 2 reason to change to had hard pipe.

1) smooth out the intake, the stock pipe is corregated...
2) stronger, the stock pipe *might* collapse in on itself at high boost pressures...

 

has any one had the stock pipe collapse on them and if so what psi

 

I'd worry more about the intake being corregated than collapsing but both are valid concerns.

 

The fact that the OEM pipe is corrugated makes it even harder for it to collapse than a straight pipe. Maybe thats part of the reason why it is corrugated stock. I like rubber better than metal since it is a better heat isolator.

 

Intake air is in the short intake pipe for a fraction of a second before it hits the turbo. Not enough time for the transmission of heat to the air.

 

The stock pipe might be convaluted to help smooth recirculation and to protect turbo by dampening. Who knows, the bottom line is that it's easy to tune aftermarket intakes at WOT for HP, drivability onthe otherhand might be and endless cause.

 

Ya I've never heard of a stock intake colapsing under high boost pressures?

 

I can confirm ETS intake drivability issues. My MAF was rescaled but simply would not idle. It caused the car to loose too much vacuum. I replaced the ETS pipe with the stock rubber pipe, kept the MAF and K&n cone. Vacuum increased from 10 in/hg to 15 in/hg at idle. Restriction...maybe, but drivibility is so much better I can't even explain. And the idle is almost stock like plus cossies.

 

No issues with my ETS intake. Minor MAF scaling and it idles perfect.

 

Anyone have issues with the samco hose? I have the amsoil filter with the vibrant adapter and it a little too long?

 

im not carzy about filter that have oil in it like peein , i like dry filters my maf is happier

i like the br pipe because it has only a mild bend and the car is smoother , ive known people
switching from one pipe to the other because of drivability issues , when there real problem is there not recirculating on the stock ecu
