PSE Mach 33 FDS Bow Review: 2026 Carbon Bow Upgrades, Speed Test and Performance Breakdown

by Zakk Plocica

The 2026 PSE Mach 33 FDS Bow represents the next evolution of PSE’s carbon platform — faster, smoother, and more stable than ever. In this PSE Mach 33 FDS Bow Review, we dive into the new FDS (Force Distribution System) Cam, test its real-world speed, and compare it to last year’s EC2 cam to see if the upgrades are worth it for bowhunters and target shooters alike.

What’s New on the 2026 PSE Mach 33 FDS

For 2026, PSE kept the legendary Mach 33 platform but introduced key changes that elevate its performance and feel. The most significant update is the FDS Cam System, which delivers a faster IBO speed of 342 FPS — up from 335 FPS on the previous EC2 cam model.

Key Specifications:

Axle-to-Axle: 33 inches
Draw Length: 25.5”–31”
Brace Height: 6 3/8”
IBO Speed: Up to 342 FPS
Let-off Options: 70%, 75%, 80%, or 85%
Weight: Lightweight carbon riser

The new FDS Cam System (Force Distribution System) enhances both speed and draw cycle smoothness. The recessed post on the cam that the cables attach to, aligning them more closely with the bow’s centerline. This distributes load more equally on the axles minimizing torque and improves shot consistency — all part of PSE’s Full Draw Stability initiative.

FDS Cam vs. EC2 Cam: The Real Difference

One of the most common questions in this PSE Mach 33 FDS Bow Review is how the new FDS cam stacks up against the proven EC2.

The EC2 cam was already known for its buttery-smooth draw cycle and forgiving valley. However, the FDS cam takes that to another level. It rolls over earlier in the draw, creating a smoother transition into the back wall without stacking or dumping off.

Zakk and Jr. from Extreme Outfitters described it as “a better feeling draw curve — smoother from start to finish, with no hand torque and a rock-solid back wall.”

Enhanced Engineering & Build Quality

PSE also refined several mechanical components for the 2026 model:

Larger Cam Bearings: Improve stability and durability.
Recessed Post on Cam: Keeps the bow balanced with minimal torque, distributes load more equally on axle.
Flush-Mounted Draw Stops: Replace the older rubber system for a firmer, more consistent back wall.
Adjustable Let-off System: Offers 70%, 75%, 80%, or 85% let-off for total control.

These updates all tie into PSE’s Full Draw Stability (FDS) design philosophy, ensuring the Mach 33 remains one of the most forgiving carbon bows on the market.

Speed Test Results: Real Numbers from the Range

During testing at Extreme Outfitters, Zakk and Jr. recorded real-world chronograph speeds using a 443-grain arrow at 70 pounds:

28.5” Draw Length: 284.1 FPS
30” Draw Length: 301.7 FPS

These results demonstrate the FDS cam’s ability to produce top-tier performance without sacrificing smoothness or accuracy. Even at longer draw lengths, the cam cycle remains consistent — no stacking, no added stiffness.

Draw Cycle, Valley, and Shootability

The PSE Mach 33 FDS draws smoothly from start to finish. Its shorter valley offers a more controlled feel, perfect for bowhunters who prefer a firmer back wall. Despite the increased speed, the bow remains dead in hand with virtually no vibration or forward jump — even when shot bare (no stabilizers or accessories).

Shooters also noted zero visible hand torque, thanks to the improved cam geometry and riser alignment. For longer draw shooters (30–31”), the string angle remains comfortable and natural, making the Mach 33 ideal for both hunting and 3D target shooting.

Dynamic vs. Static Brace Height

PSE continues to focus on dynamic brace height — how the bow behaves at full draw rather than just its static measurement. The Mach 33’s carbon riser and FDS cam maintain alignment and stability at full draw, giving shooters more forgiveness on release and tighter downrange groups.

Final Thoughts: Should You Upgrade?

If you already own the EC2 cam Mach 33, upgrading isn’t mandatory — but if you’re chasing extra speed, smoother draw, and improved shootability, the 2026 FDS version is a noticeable step forward.

The PSE Mach 33 FDS Bow is built for bowhunters who demand top-tier performance without compromise. Faster speeds, better balance, and refined mechanics make it one of the most advanced carbon bows in PSE’s lineup.

Whether you’re building a lightweight backcountry setup or a precision target rig, the PSE Mach 33 FDS offers an unbeatable combination of efficiency, stability, and forgiveness.
