I'm wondering if anyone has educated opinions about if putting a SC on a car without forged internals is a a Good/Bad/Neautral idea.

Consensus is it's fine below 450rwhp. 425 would probably be safest. Anything above that and your playing with fire. It may or may not hold. Been a couple prochargers blowing the engines in the 450+. Haven't heard a twin screw blow yet though.

Lots of folks do it without any problems. I don't know about Ford, but GM dealers have been denying warranty claims for virtually any drivetrain issues on cars that have blowers added. Seems to me like they have a right to do that, but a lot of owners seem surprised by this. (let's save the Magnuson-Moss discussion for some other time).

The LSx engines have no problems handling a blower, but the transmissions and differentials tend not to like it.
That would be my concern with any car these days.

I think some of the SC manufacturers will take over the warranty on the drivetrain.

With respect to Magnacharger and Paxton, at least, you are on your own for anything but the blower itself. Not sure about Vortech or Kenne-Bell, but these companies probably don't have the money to warrant $10,000 drivetrains when selling a $4000 part.

Dont forget that was a procharger doing mroe then 570rwhp and running nos and a miss shift!! hahaha.. yea.. good chance something blows, if anything they were suprised it would hold up as long as it did.. they dynoed the car and raced it all most every weekend at 560rwhp or more.. but I agree anything at 425+ should be good to go with a solid tune and plent of space for error... not that I would need it
