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)
yes all true. but also irrelevant imo. the only thing to care about it the end result. if it takes hp to make hp, so be it. as long as the NET hp is good enough for you. when you go up in boost, or hp goal, then yes SC wont cut it. but for this car, for most people, i still vehemently believe SC is better suited. but who knows. lets get the car, you can slap a turbo on it and make a believer out of me. and i'll do the same with a SC kit

not AS efficient, but WAY more efficient than it used to be.







but what you give up in efficiency, you gain in flat torque curve, throttle response, proportional boost, less heat, better packaging, easy pulley swaps, etc.

PS: thanks for a civil conversation on FI
