How is a supercharger less maintenance than a turbocharger? You don't have to do anything to maintain a turbocharger, where as with a supercharger, if it has its own self-contained lubrication system, you have to change it. You maintain a turbocharged engine the same way someone that cares about their car would maintain their stock engine.
If the turbo and supercharger kits are similarly priced, the supercharger kit is going to be a complete waste of money. The EFR series turbo makes the supercharger a dead technology, especially if they keep using the same outdated superchargers. >$5k for 50 horsepower and 30lb/ft is a ******* ripoff.
I really hope this turbo kit comes out some time in the next few months, as I am already getting bored with the underpowered K24Z7. It really should've come with about another 30lb/ft and 50hp from the factory, even if they had to charge an extra $1500 or so for the car. It's frustrating when luxury sedans can leave you in the dust on the highway, and there's not enough power to pass people when you have a small window of opportunity to do so. If the supercharger kit was about half as much as it is, I'd go that route, but for they money they're asking, as long as Full Race can at least match it, i'll probably end up going with them.
