Whether you’re optimizing for a sprint track or building a custom kart, the Billet Angled Engine Mount delivers unmatched strength, adjustability, and stability for peak performance.
What Is a Go-Kart Billet Angled Engine Mount?
A Go-Kart Billet Angled Engine Mount is a CNC-machined bracket that mounts the engine to the chassis at a fixed or adjustable angle, ensuring clearance from tires or seats while aligning the clutch and sprocket. Crafted from billet aluminum for lightweight durability or magnesium for racing, it includes pre-drilled holes and sometimes clamps or sliders, accommodating kart frames with tubes from 28mm to 32mm. This design enhances drivetrain geometry, making it a critical upgrade for performance karts.
Why Use a Billet Angled Engine Mount?
Angled mounts clear physical obstructions like rear tires, as noted in oval racing setups, and optimize weight distribution for better handling, a benefit you’ve explored with engine mounts before. They allow precise chain alignment without chassis mods, reduce vibrations for smoother operation, and provide DIY builders flexibility for engine swaps, making them essential for racers chasing speed and hobbyists seeking reliability.
Designed for Performance and Fit
Our Billet Angled Engine Mounts are engineered for kart chassis with 25mm to 50mm axles, offering 5°, 8°, or 15° angles and universal or Euro-style bases (e.g., 30x92mm). Available in anodized aluminum or magnesium alloy, they include M8 bolts and fit engines from 150cc to 300cc on brands like Kosmic, Birel ART, and Yerf-Dog, ensuring a robust, adaptable solution for seamless power delivery.
Key Features of the Go-Kart Billet Angled Engine Mount
The Billet Angled Engine Mount combines precision craftsmanship, versatile adjustability, and durable materials, making it a cornerstone of kart performance. Here’s what sets it apart.
CNC-Machined Billet Aluminum or Magnesium
Machined from 6061 aluminum (45,000 PSI tensile strength) or magnesium alloy (50,000 PSI), these mounts weigh 1.5-3 pounds (e.g., 8° aluminum at 2 lbs). Black or silver anodizing resists corrosion, while magnesium’s vibration-dampening properties enhance racing comfort, ensuring durability in wet or dusty conditions.
Angled Design for Clearance
With fixed angles (5°, 8°, or 15°) or adjustable plates (7°-15°), these mounts clear rear tires or seats, as seen in Briggs or clone setups, and improve center of gravity. This design ensures the clutch aligns with the axle sprocket, reducing chain wear and boosting efficiency, critical for oval or sprint tracks.
Slotted or Sliding Adjustments
Featuring slotted holes (e.g., 102mm x 80mm) or sliding top plates, these mounts allow 1/2” fore-aft adjustments for chain tension, as offered by PMI’s 8° model. Side-to-side slotted bases simplify sprocket alignment, enabling quick tweaks without disassembling the drivetrain, a feature racers value in pits.
Vibration-Dampening Stability
Magnesium alloy options absorb engine vibrations better than steel, minimizing chassis stress and driver fatigue, while optional rubberized inserts enhance damping. Precision machining ensures a rigid connection, maintaining alignment under high torque, ideal for high-RPM racing or rugged builds.
Applications of the Go-Kart Billet Angled Engine Mount
The Billet Angled Engine Mount’s versatility and strength make it suitable for a variety of karting scenarios, from competitive racing to custom projects, aligning with your interest in engine mounting solutions.
Competitive Kart Racing Optimization
In sprint, oval, or endurance racing, this mount positions engines like Rotax Max or IAME X30 on chassis like OTK or Tony Kart for optimal drivetrain geometry. The angled design clears tires on tight setups, while sliders allow chain adjustments, ensuring consistent power delivery and avoiding trackside penalties.
Recreational Kart Performance Upgrades
For club racers or casual drivers with Predator 212cc or Honda GX200 engines, the mount’s billet construction enhances stability on Manco or Yerf-Dog chassis. Its adjustable slots simplify upgrades, reducing vibrations for smoother backyard rides, perfect for hobbyists tweaking performance.
Custom Builds and Engine Swaps
DIY builders, like yourself with interest in adapters, use these mounts for bespoke karts or retrofits, fitting engines like Tillotson or Briggs LO206 into unique frames. The angled, slotted design supports non-standard setups, streamlining swaps without welding, ideal for creative projects.
Off-Road and High-Torque Environments
In off-road or dusty conditions, the mount’s corrosion-resistant aluminum or magnesium withstands debris, securing engines on rugged karts. Its vibration-dampening properties maintain alignment under high torque, ensuring reliability for trail-ready setups in challenging terrains.
Technical Specifications and Installation Guide
To ensure optimal performance, understanding the Go-Kart Billet Angled Engine Mount’s specifications and proper installation is key. Here’s a detailed breakdown.
Size and Compatibility
Our mounts fit chassis tubes of 28mm-32mm (with optional clamps) and axles from 25mm to 50mm, with bolt patterns like 3-1/8” x 6-3/8” or 102mm x 80mm. They offer 5°, 8°, or 15° angles, supporting engines from 150cc to 300cc (e.g., IAME Swift, Predator Ghost) on chassis from Tony Kart, CRG, and Hammerhead.
Material Strength and Durability
Aluminum mounts provide tensile strength up to 45,000 PSI, lasting 500-700 hours in dry conditions or 1,000 hours with anodizing in wet environments, while magnesium alloy offers 50,000 PSI and 700-1,200 hours. Both resist wear, ensuring stability under high loads.
Step-by-Step Installation Guide
-
Preparation: Measure chassis tube (e.g., 30mm) and engine bolt pattern (e.g., 102mm x 80mm). Gather mount, M8 bolts, and tools (e.g., 13mm wrench, straight-edge).
-
Positioning: Place the mount on the chassis, aligning slots forward for chain tension (e.g., 1/4” slack). If using clamps, secure to tubes at 10-15 ft-lbs; otherwise, bolt directly.
-
Securing: Attach the engine with M8 bolts, torquing to 15-20 ft-lbs in a crisscross pattern. Slide or adjust for clutch-sprocket alignment (use straight-edge to verify).
-
Final Check: Spin the clutch to confirm chain alignment and tension. Start the engine at idle to check for vibrations, retightening bolts if needed.
Maintenance Tips
Inspect mounts for cracks, corrosion, or loose bolts after wet or high-torque runs, cleaning with a soft brush and mild solvent. Re-tighten bolts after 50 hours and replace if bent or stripped, typically after 700-1,200 hours depending on material and use. Store in a dry place to prevent oxidation.
