RR Racing SuperCharger / Tuning - All GSF model years now
Just spoke with Rafi @ RR Racing. They are now able to tune all GSF model years! 
For those that want the extra horsepower should definitely give them a shout! I can say with experience you won't regret the upgrade!

There is a rumor of an LCF. Hopefully it will have a the same V8 with some FI. That would tell us how good this engine is.

Even if the rumors are true, that an LCF will have an FI motor, that motor will have internals that are designed with boost in mind.
Toyota makes great engines but let’s use the Tundra as an example, several years ago they offered a TRD supercharger kit for the tundras and the kit wouldn’t void the power train warranty as long as you purchased the kit and had it installed at a Toyota dealer. Well, quite a few truck owners found that their engines blew up and eventually Toyota no longer offered the kit, the kit availability lasted only a few years. I’m guessing that they had to replace quite a few engines under warranty which negated the profit from superchargers.
It could be that you had truck guys beating on their trucks because of them thinking the trucks engine is bulletproof, which it is. Or it could’ve been that the engine wasn’t designed to handle boost long term. Speculation on my part though.
With regards to the GSF, I think only the crank being forged could handle the boost, but not sure the piston rings could handle the boost neither could the rods since it is cast. In the drag racing world, cast rods and pistons are a no go for boost applications. Again, I’m just speculating here.

Then all hell broke loose!
