Stillen supercharger - 9lb pulley
 

Hi guys,

Could use your help. Currently I run:

- Stillen SC
- Soho A2A kit
- custom supercharger filter (4 times larger then soho)
- walbro 450 + return
- stock 8lb sc pulley
- ecutek

Last measurement, before new filter, boost was 10,2psi. I’m thinking about the 9lb sc pulley with a anti-slip pulley.

What is your experience in boost gains? Is it worth it? What to expect?

Kr, Emile
