Coolant Flow Restrictor

Circulates water slowly to keep water temperature below 50°C (122°F) with hot air induction

Negative Supercharging coolant flow restrictor has a 38mm (1.5") OD with a small tapered hole to circulate the water through the cooling system at a low flow rate of 23 L/min (5 gpm) from idle to peak rpm. This allows the radiator more time to cool the water which keeps the water temperature below 50°C (122°F) when used in conjunction with the parts of the Negative Supercharging Cooling System

The coolant flow restrictor is made from brass for longevity, should be inserted into the top radiator hose and secured with the hose clamp supplied.

DO NOT use any thermostat with the Negative Supercharging coolant flow restrictor.
