Dual Speed Supercharger?

[jersey]

Has anyone added an Antonov H3 Dual Speed Supercharger mod?

Or any supercharger mod for that matter?

What sort of cost is involved?

Does it really get you from 0-60 in less than 12 seconds?

I remember the standard superchargers being close to 6 grand. I thought the Antonov one got you close to 10 grand.
