I found these upgrade packages whilst I was searching the Internet for modifications! I'd never thought to look at 9ff before as I'd assumed they'd be monster expensive. Instead they make for very interesting reading and make the X-51 package look rather expensive! According to 9ff's site they are warrantied too. 395BHP for just over £6500. Or 420BHP for about £12000 for which you also get a fully remanufactured engine at 4.1 litres and a new clutch! And given 9ff's reputation, I would doubt these claimed figures are anything other than conservative. I can believe +40BHP when you are getting new cams and matching mapping as well as a full exhaust! And 420BHP doesn't sound unrealistic for a 4.1 litre engine with the mods described.
