If i had money, i'd love something like this! Although, my only problem is, with supercharging, what is there to really upgrade to? I.e with turbo you can up the boost easily, put a bigger turbo on ect.. But with a supercharger, change the pulleys or whatever? But then i suppose cost comes into it too.. $3,000US for a supercharger kit, probably spend all up $5,000 max getting it all running nicely... With turbo, going from what you've been doing bill it doesn't like like its been cheap :P
