Consider flooring a car at 4000 rpm in 2nd gear (with sticky tires) - superchargers and their instant response could provide a much higher instant load on the stock rods than any turbo kit.

Also I'm somewhat wary of the Rotrex kits - the number of failures (regardless of kit manufacturer) of the Rotex units is not insignificant. May be due to incorrect priming or belt tension, not sure, but the failures are there. If you have warranty coverage, your car is out of commission for weeks. If you don't have warranty coverage, you're out $1500-$2000. On the other hand, take a basic SBD kit, they sell for <$3000, add $1000 in protective goodies, and if that turbo fails it's no where near as expensive to replace as a rotrex units. Maybe the Vortech units/Eaton/Sprintex units are more reliable, don't know much about their track records.

They both have their reliability issues, any FI is a risk. End of the day, I decided my car with tune & header is quick enough

SC's are friendlier to the rods; less torque at low rpm.
