AC Crankshaft Pulley, Black. Porsche 911 3.2 Carrera 1984>>  ❭  AMS9050326

Adapt Motorsport 127/133mm AC crankshaft pulley for Porsche 911 3.2 Carrera engines from 1984 onwards. CNC-machined from 7075 aluminium, it incorporates a 36-1 tooth trigger disc for crankshaft sensing in compatible EFI installations while retaining the air-conditioning drive.

Fits

• Porsche 911 3.2 Carrera engines from 1984 onwards
  Vehicles equipped with air conditioning

What This Product Does

This pulley replaces the factory steel crankshaft pulley and provides an integrated trigger pattern for a compatible crankshaft sensor. The 36-1 configuration supports the crank-position reference required when installing a suitable sequential electronic fuel-injection system.

Functions

• Provides 127 / 133mm pulley dimensions for the specified air-conditioning application
• Retains the air-conditioning drive on compatible 3.2-litre engines
• Supplies a 36-1 tooth trigger pattern for crankshaft sensing
• Supports compatible sequential EFI conversions
• Replaces the original steel pulley with a machined aluminium component

Technical Details

• Manufacturer: Adapt Motorsport
• Construction: precision CNC-machined 7075 aluminium
• Finish: black anodised for corrosion resistance and surface durability
• Pulley dimensions: 127/133mm

Why Replacement Matters

The pulley is intended for Porsche 911 3.2 Carrera EFI projects that require an accurate crankshaft trigger reference without removing the air-conditioning drive. Adapt Motorsport uses finite element analysis during the design process to balance component strength with reduced weight. Correct sensor positioning, pulley alignment and EFI calibration remain essential during installation.

FAQs

• Is this pulley intended for cars with air conditioning?
  Yes. It is specified for 3.2-litre engines from 1984 onwards that retain air conditioning.
• What trigger pattern does it use?
  The integrated trigger disc has a 36-1 tooth arrangement for use with a compatible crankshaft sensor.
• Can it be used for sequential EFI?
  It is designed to provide the crankshaft reference needed as part of a suitable sequential EFI conversion. The complete installation also requires compatible sensing, distributor-reference and engine-management components.
• Is it suitable for a car without air conditioning?
  This version is intended for air-conditioned applications. Adapt Motorsport offers alternative pulley arrangements for engines without air conditioning.
