Re: Edlebrock Supercharged 416 Crate Engine
This is a pretty interesting discussion. I can;t say much about turbochargers, because I've never used them. But as for superchargers, anyone can buy a cheap one, as well as a junkyard LS engine, and slap them together. But is such a combo going to miraculously have the right fuel ratio and ignition curves? Will it idle decent, or will it sit at a traffic light with a mega idle surge that sometimes even causes the engine to cut out in traffic situations? What about how it will run in the cold weather on the way to work?
You don't get something for nothing. These small underhood Eaton/magnuson superchargers make great power, and efficient power with very little heat build-up as compared to the typical old school Weaind or BDS blowers. They have an internal bypass valve which prevents any boost pressures with less than half throttle inputs, and yet they're more efficient in their power delivery at full throttle because of the 60 degree helical twist of their internal 4 lobe rotors. They allow the end-user to have the best of both worlds, (reliability and gas economy for daily drivers, along with great performance).
And these superchargers aren't cheap either. But there's good reason why Jaguar, Mercedes, Aston martin, Ford, and Chevy have all chosen the Eaton superchargers for certain models of their production cars. IMO for a daily driven supercharged vehicle, you cannot beat these pieces. And everyone knows that brand new LS engines aren't cheap either. So when you have a new LS engine coupled with one of these expensive but great performing superchargers, it isn't going to be a cheap price tag. But IMO it's worth it for a true daily driver if you want some respectable power that you can actually drive around with 300+ days out of the year.
