im 100% convinced that supercharging is the way to go, for this car. we'll just have to wait and see...  |
Im 100% convinced that forced induction is the way to go SC or TC. Depending on the flow characteristics of the motor I do believe a properly sized turbo is better due to:
1) less parasitic loss on the motor, SC uses a pulley, TC obviously uses exhaust gas. This allows for more WHP because the turbo uses less of the engine's energy to operate the turbo than the SC.
2) Due to the less "drag" on the engine, fuel consumption will be very close to stock
3) with the technology behind new turbos, spool lag is almost non existent (twin scroll design, ball bearings instead of journal bearings, "exotic" compounds like ceramic)
That said though, the SC is nearly instant boost... I say nearly because there is a bypass in most modern SCs. This allows for better fuel economy at cruise speed. The bypass closes almost immediately, and much faster than a turbo builds boost. Plus I love the sound of a SC when you put the hammer down (that whine/grown makes me cum in my pants). I believe we win either way. And hopefully someone does make a SC for these cars, I'm sure Eaton will come out with one... they made some for the old cobalt ss, so they are experts in making small, very efficient SCs that play to the advantage of a "smaller" displacement 4 cylinder (that said, the roots style is not very efficient in general, but it is quite reliable and makes good power). Also if you want something more efficient, I'm sure procharger will come out with something as well.
