I was completely on my own after the kit finally showed up, wrong part supplied in the box was something that I had to source on my own. Cautionary tale on their poor customer support aside and just looking at the kit, install is not too difficult, this (and it's parent Vortech) is the only blower system where you don't need to remove the crank bolt. The Novi 1500SL does not make much noise, when you start the car you can hear something is there with an all-stock exhaust, but not much sound. So if you're looking for a loud whine such as a Hellcat, this unit is more of a speak softly and carry a big stick deal.
Sorry no meaningful dyno sheet from mine, check out the one on ECS site, that blue car is owned by a member here. I ran in the high-10s on the dragstrip with the base blower kit (I had added a baro breakout) and no methanol injection in summer heat, in an A8 car with the stock torque converter. Clarification on base kit, when KingLT1 mentions Reckless' car, I believe that he meant it was the base drive system and the base head unit, as that car was indeed pullied faster than the true base system is when it made 800hp with methanol injection on a built motor and long tubes. Base drive system is the jackshaft on stock serpentine system with a separate cog belt going to the blower, and base head unit is a 1500SL. There is now a 10-rib dedicated drive system available from Vortech, and a 2200R head unit (upgrades beyond the base kit).
Fuel system upgrades are a really great idea that you should STRONGLY consider for a supercharger install. Mine with a stock engine, all-stock exhaust, base pullies, and no methanol injection system, was losing high side fuel pressure and the injector pulse width was excessive with the stock LT1 hpfp and injectors. This problem is far more common in my opinion than many people realize. I was datalogging my car, whereas most customers do not, and therefore they would not know whether something was not up to snuff. Hasn't blown up yet is really not the same thing as fuel system working properly.
I would also suggest that you get a baro breakout kit for any of these centrifugal kits, because BARO coming from the MAF (after the compressor) gives bogus data when you read your logs. It's not a power-adder thing like methanol injection or headers, just for good data.
