928 motorsports has a billet T trim impeller and claims 15% increase across the board with their impeller and a 60k limit

does anyone have one of these or are there any other better billet upgrades out there?

I'm about to max out my t-trim and would like some extra psi if I can get a billet impeller for $500

If your running a meth kit try sticking a small nozzle right in front of the impeller ....defiantly worth a bit

I am, but what does a nozzle in front of the impeller do?

Turpid porpoise

Improves the efficiency of the compressor by cooling the air before/while it is being compressed.

I have two #7's(I think) in the charge pipe. What would you guys recommend to put in front of the compressor.

I'm assuming I could also just t this one with my main lines, correct?

Something small like a 3 ...you can t off your lines but I think u need a check valve or something ....call Julio at alkycontrol

Turpid porpoise

I have the billet impeller from 928 on my V2. I saw ~1 psi increase (I'm now at 14 psi) over my S trim at the same speed (56k). I also had the ceramic bearings (rated at 72k rpms) installed so I could pulley down if I wanted.
