i agree the guy is right, but you gotta also consider the TVS series of roots type blowers, much more efficient and properly sized wont give up much, if any, top end power, being nearly as thermally efficient as a centri as well. the old M62 that lotus used is 2 steps behind the current stuff.
also fuel economy between a roots that has a by-pass and a centrifugal should be very comparable. if you are worried, go the the roots and drop your axle ratio to 3.7:1 would be comparable or better than stock. instant boost gives extra torque/power that the centrifugal cant match.
Assuming about 26% drivetrain loss (MT)
i ran a basic (very basic) test having a flow map for the R1050 TVS blower and R1320 just because. and got about 240rwkw, power peaked at 6900rpm (with both) at 10 and 9psi respectively. turbos are doing that at 9-10psi. the R1100 that i've emailed eaton about is even more efficient and would produce about 250rwkw at 7000 (330whp) at 10psi (72% thermal efficiency above 4000rpm) meaning a good A/W intercooler could bring temps the within 15% of ambient (similar to a centri with good air to air)
