Default Two ST76s

Just curious if someone were to build a LSX 440 or a 454 both with a 4.185 bore and strap two ST76 T6 rated at 1200hp would that engine be capable of making 2000hp?
Basically if you have two turbos rated at 1200hp each does that mean you can double that because there is two turbos for a total approxmite of 2400hp?
If No, why?

Problem is, it would take about 50 psi boost to get there.

Default s76

Would a pair of s76 make more power than the st76's on the same type of motor? (all out race lsx427) What would the spool and power be like on both compared to a 106?

I know a certain mustang that is being built with two bullseye turbos that are essentially twin ST80's with race covers and it's only going on a ~300CI motor

S76 would make more power indeed, but spool up would be a little slower. As for power compared to a 106, it should out power a 106 due to backpressure drop alone it would be more efficient.
