A hard question for someone really clever!
I've just been reading the latest issue of EVO UK magazine (issue 065) and they have a full behind the scenes article at TVRs Blackpool factory, covering the development of the upcoming Sagaris and Typhon models. They have a whole section about the supercharging of the Speed Six engine for the Typhon with an interview with the guy in charge of the project, Simon Hindle. In one paragraph they (attempt to) describe the mechanicals of the custom designed Rotrax supercharger. Now I consider myself to have a fairly good grasp of technical engine type stuff, and know the basics of forced induction systems, but this went WAY over my head! :confused:
"Inside the Rotrax's casing, the epicyclic drive comprises three steel rollers surrounding the drive spindle. One has an arm connected to the spindle and the faster the crank-driven outer casing turns, the harder the rollers engage."
Can anyone please enlighten me as to what the hell they are on about??!!
