I have only ever seen it done once (Cyrus on here, twin rotrex supercharged DBS) and have never heard what came of the project. I have discussed it at length with BBI Autosport a long time ago, and at that time decided NA was fine, but the desire has come again. I have been extensively warned about being a guinea pig for such a project, but as no one else is doing it I want to see what the possibilities are. If anyone could recommend some top tuning companies in North America that you believe would be able to undertake a project of this scale that would be greatly appreciated. Thank you in advance, I look forward to seeing your suggestions.
