T3-X1 Engines

Hi this is my creation for a more sensible engine duo on any SSTO or even Distant star traveler Here I have two sets of boosters called the “T3 Engines” and the “X1 Engine”

There lots of technical data but the biggest of all it is right here
X1 Engine:
- A modified Mage engine now capable of bringing 40+ tons into orbit at 50% fuel cost of normal engine
- Vacuum efficiency increased by 42% compared to atmospheric (110km+)

T3 Engines:
- A smaller version of the X1 Engine with a few size reductions and power reduction all around however two of the three engines have extended nozzles for 17% atmospheric thrust efficiency.
- has -19% fuel usage however so these are definitely the world leaving engines lol.

Will get updated but I’m trying to make these for something way bigger but d thought I’d share them and see what the community says :)

Thank you for trying!
