I recommend of course what I did. I did a test drive side by side with a Perf and a 720 3 years ago. Anyone can do it at Dream Racing or Las Vegas Speedway $499 for 5 laps with an instructor(very helpful). Now I am comparing both cars on a track with an instructor. There was no comparison how much better the Perf was handling for me was and of course the sound. Flash forward 1 year, and I set up an appointment with Nik the head of VF. He invited me over for a test drive of his SuperCharged Perf, and that sealed the deal. 6 months later Nik was my co-driver on 10 days of Gold Rush Rally through 10 States. First day, I drove in the morning, I drove driving my usual 5,000-6,000 rpm. After lunch Nik drove, and we were surrounded by 100 super cars, and Nik causally said my Perf was the fastest, but I did not know how to out perform a 720 or Bugatti. He shared that I that a super charger sweet spot was in the low rpm of 2,500 to 5,000. He then proceeded to out perform the 720's with easy. Seeing is believing. Go ahead and give Nik a call, and get the information from him. Share my name or not, I think it is better to surprise him and not mention my name.I'm not 100% sure I will do it yet. Will get car and put a couple thousand miles on car before I decide. Coupe will be faster than my current spyder and if I can get 0-60's at under 2.5 and 1/4 around 10 I may keep it stock. But if I decide I want more then VF will be what I go with. No downside at all from experience with supercharging, car behaves exactly like stock until you want the extra power and keeps the car feeling more NA than going turbo's. Install on my lp610 took 3 1/2 days and I'm sure you can find many component shops in your area to do install. VF will also give you names of shops they recommend.
My car is working fine, and I have added 10,000 since adding the supercharger. As to warranty, that is simple, if a major problem just unbolt it, and bring it to the dealer. In my case, no problem because I believe I am currently out of the warranty period. Lambo fortunately are bullet proof to a large extent, and a supercharger is as radical power boost as twin turbos.
I believe we are living in interesting times. I noticed that Ferrari has introduced hybrids in general production. I hope at Pebble Beach Lambo will make an announcement about some changes especially for an A which is getting way long in the tooth. I have enjoyed my Lambo with the VF mod, and see a good reason to change nothing.
