Don't forget they have a gearbox inside them, so the 10,000rpm input shaft speed gets turned into near 100,000rpm exit turbine speed similar to a turbo. ![]() ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone ![]() |

Fatlapit I think you are getting confused mate.High boosts rev to about 8 k low booost around 7.5 We are talking about changing the pulley size to get more power lower down but that means you would need to limit the rev's lower to prevent the SC from spinning at silly speeds ________________________________________ Ex- Phase 3 China GTi-6 T-Reg |
