All of my fastest time trials were on a circa 2000 aluminum Tiemeyer.
Bikes weighed 21.5 lb. with disc and aero front wheel.
I even rode this bike to 5th place in an NRC level tt that was uphill.

After that I thought a faster bike would make me faster. Went through a Teschner, Cervelo P3, Trek Speed Concept, Felt (whatever their carbon tt bike was), and Specialized Transition.

Good legs and good position trumps most.

Is that a 650 front, vs 700 rear? I thought they were equal wheel size.

Looks great, but I would go TR rear...just for looks to match.

Probably 45sec/40k max.

The biggest aero issue with that frame is the exposed shift cables along the downtube. Etap would clean that up.

~40s/km is the difference between a p2 (old) vs p5 frame.

A lot of the improvement from the P2 to the P5 is in the cockpit and front brake as opposed to the frame.

The OP's already fairly optimized these.
