Hayden (of WEVO) said years ago that anything over 300 ft/lbs below 3000 RPM was a crap shoot - that nothing you did would make a 915 reliably stand up to that.
930s with a half-decent (eg 30 year old) turbo tend to make 80% of peak torque around 3000 RPM. Higher revving (eg N/A) motor, especially in a lighter car, without big sticky tires and hard launches does improve the odds. 915 internals do look shockingly puny next to G50 parts though.
I ran a built 915 for some years with 370 wheel HP from a CIS 930. It involved many compromises, including an anti-social clutch to hold the torque and babying it/driving around the weak points. It broke enough parts (including eating 4-5 teeth off an aged 2nd gearset when I wasn't even trying) that you really never forget that you're pushing the envelope and your luck.

Good to know.
I only street and highway drive mine with some spirited canyon carving. I try to be "gentle" with the shifts and never abusive with launches.
