Does my car have an aftermarket lower pulley????/
 

I was told when purchasing the car that it had a eurocharged lower pulley. The car does have headers with no cats, however my boost numbers according to logs only hit about 10.8 psi

Here is a picture of the lower pulley. Does anyone have a picture of the stock pulley on their car that i might be able to compare with

Yes looks like an asp 180 to me. Someone correct me if I am wrong.

Hard to see the step from one pulley to another

ASP also makes a 175mm. They provide a smaller water pump pulley for clearance and it looks like theirs in the photo, I'd have to look at mine to be sure.

Does it have k&n filters. The edges of your rotor in the supercharger might have extra clearance from the fine grit getting in.

headers may cause your reader to show lower boost numbers

Is it not easier to just measure the pulley instead of guessing from a distance?

I have a crank pulley on my E63, but have no pictures to post for comparison.

i tried to measure but couldnt get an accurate reading. Pretty tight fit
