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.

I don't think there's evidence to back that up as a concern, especially not with centri's that are only generating a few psi anyway at that rpm. Throttle tip in programming can control this if it's a problem.

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.

I agree on the Rotrex units. Turbos leak and fail too though. I would not expect the turbo in a $3k kit to outlast an Eaton TVS.
