The AKMSpeed Process

Our porting service is a comprehensive overhaul of your blower's internal geometry to reduce turbulence and increase air velocity.

1. Disassembly & Inspection: Upon arrival at our facility, your supercharger is fully stripped down, and the factory oil is drained.

2. Precision Porting: Arthur at AKMSpeed expertly re-profiles the inlet and outlet ports of the R1320 case to optimize airflow paths.

3. Decontamination: The case undergoes a thorough cleaning process to remove all metal shavings and debris from the porting stage.

4. Fluid Service: The unit is reassembled and refilled with premium-grade supercharger oil.

5. Optional Maintenance: We offer a full bearing rebuild at an additional cost for customers looking to refresh high-mileage units during the porting process.

Proven Performance Gains

The Eaton R1320 responds exceptionally well to specialized porting. On average, customers can expect:

• Boost Increase: 2–3 lbs of additional boost pressure.

• Power Gains: Approximately 15–20 whp per pound of boost.

• Result: A total potential gain of 20–40 whp, depending on your supporting modifications and tuning.

Ported Supercharger Service FAQ

Do I need a special tune for a ported supercharger?
No dedicated "ported" tune is required - your existing Stage tune should accommodate the extra airflow, but always confirm with your tuner before installing, especially if you're also running a smaller pulley.

Will this work with my current pulley?
Yes - this service is designed to raise your boost ceiling without requiring a pulley change, though it pairs well with our TruDrive crank pulley for owners chasing more.

What's the difference between the Custom and Factory options?
Factory keeps the stock housing finish; Custom is available for buyers who want a different housing appearance after porting.

Can I add throttle body or Ultracharger porting to this order?
Yes - since Shopify limits us to 3 built-in options on this listing (core, bearing rebuild, color), throttle body porting and Ultracharger/Superduper porting are offered as separate $150 add-ons below. Just add the ones you want alongside this service and we'll perform them together.

Does this fit my Audi?
If your core uses the Eaton R1320/TVS1320 supercharger from the EA837 3.0T platform, yes - check the Vehicle Fitment table above, and reach out with your VIN or part number first if you're not sure.
