C9
¥30,400
市场上最好的无氧竞赛燃料混合物之一。
对于任何想要从泵气切换到比赛混合燃料的赛车手来说，C9 都是完美的选择。事实证明，C9 的功率明显高于 Pump 98。与泵气不同，C9 在批次之间始终如一地混合，永远不会让您失望。它不含任何乙醇，也可用作储存燃料。
C9 是一种符合 CAMS Schedule G 规定的商用燃料。

NON-OXYGENATED FUEL
tuning info
No added oxygen content, so fuel delivery remains closer to conventional petrol.
Does not require the richer compensation typically needed with oxygenated race fuels.
Still tune to the fuel’s specific requirements and verify with proper calibration tools.
What is Oxygen Content?
Oxygen content refers to the amount of oxygen within the fuel itself. Higher oxygen content allows more complete combustion, increasing power potential while requiring additional fuel delivery to prevent lean conditions.

Fuel Delivery Remains Very Close To Standard Petrol
Tuning Info
Stoichiometric AFR is extremely close to standard petrol.
Does not require the richer compensation typical of oxygenated fuels.
Always verify calibration with proper AFR or lambda tuning methods.
What is Stoichiometric Air-Fuel Ratio?
The stoichiometric air-fuel ratio defines the ideal mixture for complete combustion. Different fuels require different ratios, meaning fuel delivery must be adjusted during tuning to maintain correct combustion and performance.

C9 is less dense than pump fuel, requiring increased fuel volume.
Tuning Info
Lower density means less fuel mass per volume.
Increase fuel delivery to maintain proper AFR.
What is Specific Gravity?
Specific gravity measures the density of the fuel relative to water. It determines how much fuel mass is delivered for a given volume. Lower density fuels deliver less fuel mass per volume, which can cause a lean condition if not corrected.
Reid Vapour Pressure
6.89 PSI
MODERATE–HIGH FUEL VOLATILITY
tuning info
Higher vapour pressure improves evaporation and throttle response.
Supports cold start and transient fuel delivery.
Monitor system temperatures to manage vapour-related behaviour.
What is Reid Vapour Pressure?
RVP Measures the volatility of a fuel and how readily it evaporates at a given temperature.
In forced induction applications, a lower RVP resists vaporisation under boost, reducing the risk of vapour lock. Naturally aspirated engines benefit from a higher RVP, where easier vapourisation improves atomisation and throttle response.
