T-33 engine option?

[DaveKDEN]

There is an option in the iniManager to select between the official engine flight model and the Electron Volt Allison model for the iniBuildsT-33. Can someone provide a quick explanation between the two different options? Also curious what option most people are using...
I'm now using the FS2020 version in FS2024 due to the add-on repaint compatibility issue with the FS24 version. So many EXCELLENT repaints out there!
TIA

The original/official product flight model was done to match a Canadair CT-133, so the engine performance was modeled after the Rolls-Royce Nene engine as those have fitted (although that wasn't originally stated anywhere by iniBuilds). The original Lockheed T-33, however, is/was fitted with the Allison J33 engine. The Rolls-Royce Nene engine is all around a better option - it doesn't have nearly as much spool-up lag as the Allison J33, and it also has greater top-end performance than the J33. But, if you want a truly original 1950s American-made T-33 experience, it would be with the Allison J33.
