The engine has been changed to a supercharger, exhaust and shocks changed too. Not sure how much of the engine has been retained.
I won't mind extra power but I was never a fan of aftermarket tuners too. I feel that they remove the originality and soul of the whole car. It becomes just a fast machine. And most of the time, their modifications to the appearance of the car are just distasteful. Thankfully, Novitec didn't really mess with the looks of the 430 too much.
I spoke to the Novitec Rosso guy from Germany and he said that the engine is NOT modified. The only upgrade for power is from the supercharges, exhaust, ecu.
However from my Ferrari experience, always got some warranty parts to claim. When the new workshop will be up?
