Eaton M45 Supercharged 3S-GE Setup! 👈 Tune Setup 👈 Home 👈 Follow US 👈 Lets Collaborate 👈 A 3S-GE Motor A “complete” Eaton M45-supercharged 3S-GE setup is basically an exercise in packaging a small positive-displacement blower so it feeds the engine cleanly, stays cool, and can be tuned safely. The M45 itself is a roots-type supercharger with about 45 in³ (0.74 L) swept volume per revolution, so it’s well suited to modest boost on ~2.0 L engines when spun within reason and paired with a bypass valve for drivability. Mechanically, the heart of the build is the mounting bracket + belt drive and the intake manifold/adaptor. You need a rigid bracket (no flex = stable belt tracking), correct pulley alignment, an idler/tensioner arrangement that keeps belt wrap on the blower pulley, and an inlet tract that doesn’t choke the M45. On the outlet side, you either fabricate a manifold that puts the blower discharge into the plenum evenly, or you run a short discharge into a plenum box feeding...

Eaton M62 Supercharged 3S-GE Setup! 👈 Tune Setup 👈 Home 👈 Follow US 👈 Lets Collaborate 👈 A 3S-GE Motor A complete Eaton M62–supercharged 3SGE setup begins with understanding the fundamental nature of the engine family itself. Across all five generations, the 3SGE is a high-revving, naturally aspirated 2.0-liter engine with strong cylinder head flow, relatively high compression, and a reputation for durability when kept within its design limits. The Eaton M62, being a Roots-type positive displacement supercharger, pairs well with these engines because it provides instant boost and strong midrange torque without the complexity of turbo plumbing. However, because most 3SGEs were never designed for boost from the factory, the success of an M62 build depends heavily on conservative boost pressure, excellent tuning, proper cooling, and strong fuel delivery. The goal is not maximum dyno numbers, but rather a reliable, street-friendly power increase that complements the 3SGE’s naturally r...
