Compressor covers??

[Z SKI]

Hey guys, since i have been looking at new turbos recently, i noticed that PTE has a few compressor cover options. I know that i want a S cover, but i saw a ported S cover option. What benifits do the ported holes have?? This would be a PTE 6776R dbb turbo if that helps. Let me know. Thanks, Paul

i believe the ported comp cover looks like this, however the cover pictured is an H (larger w/ 3" discharge)

The porting supposedly resists surge in part-throttle boost conditions.

Thanks Mike and Dig. The one i saw had a bunch of little drill holes going around the inside of the air inlet. Resist part throttle surge, good enough for me. Paul
