It'll feel lower geared down to the tire sizes, internally the gearboxes are the same ratios.
That is a possibility. I should have stated in the original post where the info came from as it is hearsay; although from an owner of both machines.

I use the 915 but cannot recommend it as each person has different driving habits. You absolutely cannot beat on the 915 or it WILL fail. This takes some enjoyment out of the driving experience if you are a person who likes drag race starts and speed shifting. I find that neither will help me get down the road faster so I let the engine do the work. The tires break when boost hits which is presumed to be less shock than a drag start.
Both of my 915s have the same mods, WEVO bearing retainer and late model (Carrera) side plate. Another mod that will further protect the tranny is an LSD. This will distribute the "punch in the nuts" that boost gives the side plate equally to both sides.
