- Aluminum & PEEK (Polyether Ether Ketone)
- Parts
- Crankshaft parts, intake systems and bearing housings
Background
Engine Mods on a Hobbyist Budget
Arco Aria has raced tether cars for a decade and modifies nitro engines part by part. Each change needs a small batch of precision parts rather than a production run, and the budget is personal.
Key challenges
Small Batches
One-off quantity usually pushes shops into prototype pricing.
Tight Tolerances
Crankshaft and intake parts sit inside a running engine.
Material Behaviour
Aluminum and PEEK behave differently under heat and load in the same assembly.
How the Engine Parts Were Machined
Quotes came back through the online platform with DFM analysis, and the parts were machined and shipped in the quantities the build needed.
CNC Machining
Aluminum and PEEK parts were machined for the crankshaft and intake systems.
Small-Batch Delivery
Parts shipped in the quantities the build needed, with order tracking through the platform.
Engine Rebuilt and Back on the Track
The modified engine went back into the car with the new crankshaft and intake parts.
After delivery
Parts That Fit the Engine First Time
The machined parts matched the drawings, so the rebuild stayed on schedule and the car returned to testing.
Small-batch parts with no minimum order
Customer perspective
The parts came out exactly as needed, and Olivia kept me updated through the whole process.
