Twice now when my turbo has been sent back to TD's the compressor wheel has been 'dusted' (chipped). Has anyone had this before?

I'm running a standard PD130 airbox with a Pipercross panel filter and a PD160 in-take. I really don't want it to happen again and my mechanic can't find any reason why it would be happening. :no:

Can only be caused by large particles getting past the air filter. I would check the panel filter micron size versus the OEM paper filter. Some after market filters allow more air by increasing the filters micron size, which in turn allows larger particles of road debris through the filter.

Ali uses the same one in all his cars though, I think the mappers give a free filter away for every map they do, but this is the first I've heard of it... :(

Turn the map down!! 240bhp from a piddly stage 2 is killing it

no matter what the cars running or the boost etc, the only way to damage the compressor wheel by chipping is by something getting through the air filer, itd be different if it was the bearing or the seals, has the pipercross got little metal sqaures on it holding the foam in shape hasnt it? im wondering if any of these has got dislodged, they have probably been fine on other car as the boost/mods etc arnt as much as whats on yours, Id say go back to a standard filter. Also you have the pd160intake dont you, has the flap been taken out on the end as this is meant to stop large obsitacles getting through, but then they still shouldnt go past the filter

Not having much luck are you.

I binned my pipercross one as it had foam on the bottom and it detached itself from the filter/broke up

Can only be upstream of the compressor. Possibilities would be something in the intake piping, badly fitting filter, "something" breaking up or damaged, possibly in the MAF tube. I can't recall if any of the PCV system goes near those areas... Possibly, there's one post MAF but pre-compressor.

Whip the inlet pipes off and have a damned good look.

That wouldn't explain why it's being chipped though...

...and I spoke to Joe from TD who rebuilt my turbo last week and he said it doesn't look like it's under strain at all. He said he can physically see if I'm running too much boost and it looks fine and even said I can put more through it if I want to...

ran a bmc for 40k no problems, id be ditching the piperx for sure, 2 times over especially

Stick a standard air filter in, You wont lose power but it will filter better.
