It`s a blessing in disguise really. The last thing VF want is for engines with stock internals to start failing and jepordizing their reputation. Built internals is the way forward at this sort of level.
If you can get January`s Performance BMW there`s a custom ESS VT car in there built by the raceshop that did mine, with support from ESS. It`s using a maxxed out T trim with the simillar charge-cooled intake to VF and its putting out a genuine 700hp on Dyno Dynamics with pump fuel and no Junk in the Trunk.
I`d expect the VF Stage 3 to be very close to this.
