Max power for factory drivetrain and engine internals
What would you guys say is the max amount of power the factory drivetrain and engine block will hold reliably on a street machine that sees track time often? I'm talking stock engine internals with upgraded cooling and fueling only, reliable pump gas fuel and ignition tune. Supercharged or turbo charged boost. And maybe a clutch, all else factory components.

Tranny is "medium" torque rated... I would think you'd start having problems around 300-350 whp. But that's just my ballpark idea from a couple threads on here.

Nobody knows any hard facts but I'll throw my opinion
A properly tuned motor could run on e85 with 500whp or so A gearbox won't last long over 300tq ( with my driving style such as flat hard ass shifting daily ) The diff with an upgraded CF shaft only would last some time if you don't launch it with stickey ass slicks Clutch would start bitching over 270~ Fuel system at 300 ? Everything I stated is just me assuming stuff.

The oil pump has a variable gear to save gas. In the torque dip its actually designed for lower pressure rate of increase than the typical 10 psi per 1k rpm. So add a bunch of torque in that rpm range with boost ? Weird things like this are just now being uncovered and dealt with. If you really drive the car (more than a few daily WOT pulls on the highway) follow Dezoris's build videos, it is a very smart approach, I think he is around 220 rwhp.

I realize that guys have gone way over 400WHP with the factory engine with boost and E85 tunes, but the reliability and longevity of this type of setup is questionable especially under the rigors of track time. For this hypothetical situation I'm only concerned with boost and pump gas. No E85, no alcohol/meth injection, no race fuel, just pump gas.
