PowerCarb4 15S-3 Sliding Carburettor<\/b><\/h2>\n

When it comes to engine performance, the carburettor defines the character.<\/p>\n

The PowerCarb4 15S-3 Sliding Carburettor is a genuine ZR.32X Competition spare part – and a serious performance upgrade for the ZR.21, ZR.28 and ZR.32 Series.<\/p>\n

\u2022 Competition-proven 3-needle slide carb design
\n\u2022 Precise adjustment of idle, mid and top-end throttle range
\n\u2022 Thermal isolation for consistent performance
\n\u2022 Increases power and tuneability
\n\u2022 Required venturi inserts are not included<\/p>\n

Matching Venturi Insert<\/b><\/h2>\n

To perfectly tune your engine performance, Venturi Inserts are available separately in:<\/p>\n

\u2022 6.5 mm – #38545<\/a> – For more information, click HERE<\/a>
\n\u2022 7.0 mm – #38546<\/a> – For more information, click HERE<\/a>
\n\u2022 7.5 mm – #38547<\/a> – For more information, click HERE<\/a>
\n\u2022 8.5 mm – #38548<\/a> – For more information, click HERE<\/a>
\n\u2022 9.0 mm – #38549<\/a> – For more information, click HERE<\/a><\/p>\n

They directly influence airflow velocity inside the carburettor – and therefore torque curve, throttle response and peak power (for more details see picture attached).<\/p>\n

Smaller diameter:
\n\u2022 Increased runtime
\n\u2022 Improved drivability on low grip tracks<\/p>\n

Larger diameters:
\n\u2022 Increased power
\n\u2022 Ideal for high-speed layouts and high grip conditions<\/p>\n

Whether you\u2019re chasing power, torque, top speed or maximum consistency – the combination of PowerCarb4 and matching venturi inserts gives you the tools!<\/p>\n
