Engines

Engines are Components that modify a Railjack's cruising speed and boost capabilities. Stats are randomized within a range determined by the item's House and Tier.
A Railjack's base Engines stats are:
*Engine Speed: 150 meters per second
*Engine Boost: 1.3x
Avionics are applied to these base stats, and then the equipped Engine's values are added on.
Total speed can be calculated using the following formula:
Base Boost Multiplier is 1.25x, and the bonus from Engines is additive, but at least in the UI, the Boost Multiplier is rounded to the nearest .1. For example, an Engine with +0.17 Boost Speed Multiplier would show an Engine Boost value of 1.4x.
==Houses & Tiers==
Engines stats vary between Houses, but the differences follow the same pattern:
*Lavan Engines touted the best boost speeds, but struggled to compete at top speeds.
*Vidar Engines were the best in class for top speed, at the expense of Boost performance.
*Zetki Engines were solid performers in all categories but stood out in none.
