I was wondering how long it would take to get a thread like this going haha.
There are so many variables the factor it to "better."
Better for feeling fast----Turbo (more change in power per RPM) whereas an SC will be linear, and a screw or egg beater type will give great benefits down low.
Better for maintenance---Toss up, depends on boost and tune.
Both solutions have bearings that will wear and need rebuilding periodically. Since the SC has a more characterized duty cycle (ties to rpm) the runaway forces will not stress the system as much. Both generate heat, (thermo PV=nRT) but since the turbo has an extra efficiency loss running off the high temp exhasut gasses, it will require more from its bearings.
Naturally my opinion for the F would be a roots or screw type blower......then a twin turbo setup
I have just never been a fan of how turbos fial and what they take out with them. You get a bad wastegate spring or boost controller or blow off valve and you can cause some damage. Also that steep change in HP when the turbo spools has never sat well with me thinking about what the piston experiences. The reliability of a system is the sum of its parts, and turbos will require more redundancy and gaurd bands than an SC, but it will always feel faster because you feel the power kick in more.
This is one of the age old arguments and I think it boils down to personal preference. With a turbo you can build you engine 700HP, drive at 400 all day long and kick it up when someone challenges you. On an SC, you just build to where you want to be. Easier to tune, not as many corner cases etc.
The V8 lend sitself to SC, due to the intake mani being in one column. You get to group all of the intakes in one shot.
