PTE 76/75 power rating ?????

[chevyII]

PT 76/75 CEA H cover 4" in 3" out .96A/R with a 3 5/8 discharge rated at 1200hp.

PT 76/75 GT42 cover not sure on inlet outlet size but the A/R .98/.1.12/1.28 with a 4 5/8 discharge rated 1200HP

Can they both be 1200hp with over an inch difference in the turbine outlet and the GT42 cover?

I will give my uneducated guess at this. The HP numbers are a general guide. There are alot of turbos that go way above the rated HP. Then again there are alot of people that fall way short of these numbers too. As far as housings go, I see the compressor cover size and exhaust outlet size playing a small role in power. Probably only noticed when the turbo is being pushed to the max. There isn't a different HP rating for most smaller turbos when dealing with the E,S,H covers, or the .63, .85 exhaust either.
