Porsche cayman 981 S technical specifications and performance metrics
DFI 3.4-litre Flat-Six engine architecture and power delivery
The heart of the 981 S lies in its meticulously engineered 3.4-litre horizontally opposed six-cylinder engine, designated internally as the MA1.23 powerplant. This sophisticated unit generates 325 horsepower at 7,400 rpm and 273 lb-ft of torque at 5,800 rpm, representing a modest but meaningful increase over its predecessor. The direct fuel injection system operates at pressures exceeding 150 bar, enabling precise fuel delivery across the entire rev range whilst maintaining exceptional combustion efficiency.
The engine’s architecture incorporates several advanced technologies that contribute to its remarkable performance characteristics. Variable valve timing on both intake and exhaust sides optimises power delivery throughout the rev range, whilst the integrated dry-sump lubrication system ensures consistent oil supply during high g-force cornering scenarios. The compression ratio of 12.5:1 extracts maximum energy from each combustion cycle, though this high compression demands premium fuel for optimal performance and longevity.
PDK Dual-Clutch transmission vs manual gearbox characteristics
Porsche offers two transmission options for the 981 S, each providing distinctly different driving experiences. The standard six-speed manual gearbox delivers unfiltered mechanical engagement with precise shift action and a relatively short throw between gates. The clutch pedal weight remains manageable during extended driving sessions, though traffic conditions may prove tiresome for some drivers. Manual transmission variants typically command higher prices in today’s market due to their increasingly rare nature.
The optional seven-speed PDK dual-clutch system represents one of the finest automatic transmissions available in any sports car. Gear changes occur in milliseconds with virtually no interruption to power delivery, whilst the system’s ability to pre-select the next gear ratio ensures optimal performance during dynamic driving. PDK-equipped vehicles demonstrate superior acceleration figures, achieving 0-62 mph in 4.7 seconds compared to the manual’s 5.0-second benchmark. The transmission’s sophisticated electronics integrate seamlessly with other chassis systems to optimise traction and stability.
PASM adaptive suspension system and chassis dynamics
Porsche Active Suspension Management represents a cornerstone technology in the 981 S’s dynamic repertoire. This electronically controlled damping system continuously adjusts shock absorber firmness based on driving conditions, road surface quality, and selected drive mode. The system incorporates accelerometers and gyroscopic sensors that monitor vehicle movement in three dimensions, responding to inputs within milliseconds to maintain optimal wheel contact and body control.
The 981 generation benefits from a longer wheelbase and wider track compared to its predecessor, contributing to enhanced stability and reduced lift-off oversteer tendencies. The chassis employs a sophisticated blend of steel and aluminium construction, achieving a 40% increase in torsional rigidity whilst reducing overall weight. This combination of increased stiffness and reduced mass translates directly into improved steering precision, reduced chassis flex under load, and enhanced feedback transmission to the driver.
Braking performance with PCCB ceramic composite discs
Standard braking equipment on the 981 S comprises ventilated steel discs measuring 330mm front and 299mm rear, operated by four-piston and single-piston calipers respectively. However, the optional Porsche Ceramic Composite Brake system elevates stopping performance to extraordinary levels. These carbon-ceramic discs resist fade under extreme conditions whilst reducing unsprung weight by approximately 20kg compared to steel alternatives.

The distinctive yellow calipers serve as immediate visual confirmation of this premium braking package, though replacement costs can exceed £6,000 for a complete set. Many enthusiasts consider PCCB essential for track use, where the system’s resistance to thermal degradation provides consistent pedal feel throughout extended sessions.
Pre-purchase inspection protocol for porsche cayman 981 S models
IMS bearing assessment and intermediate shaft failure prevention
Unlike earlier Porsche engines, the 981 generation’s MA1.23 powerplant does not suffer from the intermediate shaft bearing failures that plagued previous models. The engine’s revised architecture eliminates the problematic IMS bearing entirely, representing a significant reliability improvement. However, thorough inspection of oil condition and engine internals remains crucial for identifying potential issues before they develop into costly repairs.
During pre-purchase inspection, particular attention should focus on oil analysis results and any evidence of metallic contamination. The sophisticated direct injection system requires specific oil specifications, and deviation from Porsche’s recommended service intervals can accelerate component wear. Engine bay inspection should reveal no signs of oil seepage around the crankcase split line or valve cover gaskets, as these areas indicate potential internal pressure issues.
RMS rear main seal leak detection and replacement cost analysis
Rear main seal leakage represents one of the most common maintenance issues affecting 981 S models, particularly those approaching 60,000 miles or seven years of age. This seal prevents oil from escaping where the crankshaft exits the engine block, and failure typically manifests as oil accumulation on the transmission bell housing or engine undertray. Detection requires careful inspection of the engine-transmission junction area, often necessitating removal of protective covers for proper assessment.
Replacement costs for rear main seal failures range from £1,200 to £2,000 depending on labour rates and additional components requiring renewal during the repair process. The procedure demands transmission removal, making it advisable to address clutch replacement simultaneously on manual transmission vehicles. Prevention through regular oil changes and avoiding extended high-temperature operation significantly extends seal lifespan and delays this inevitable maintenance requirement.
Bore scoring inspection using borescope technology
Bore scoring, characterised by vertical scratches in the cylinder walls, can affect 981 S engines despite their generally robust construction. This condition typically results from inadequate lubrication during cold starts or prolonged high-temperature operation. Professional borescope inspection through spark plug holes reveals the condition of cylinder walls, piston crowns, and valve faces without requiring engine disassembly.
Early-stage bore scoring may not significantly impact performance but indicates potential future problems requiring attention. Severe cases necessitate complete engine rebuilds costing £15,000 or more, making pre-purchase detection absolutely critical. Signs of bore scoring include metallic particles in oil analysis, elevated blow-by readings, and unusual engine noise during warm-up periods. Regular oil analysis and adherence to warm-up procedures significantly reduce the likelihood of developing this condition.
