TracTuff P72 Swirl Pot

Description

The swirl pot is our customers’ top choice for P72 (B18C1) cylinder head cooling system upgrades! It offers the best solution for vehicles with tucked radiators, radiators without a fill point, or situations where you simply want a higher fill point to aid in burping the sometimes troublesome cooling system.

The swirl pot starts with a beautifully machined 6061-T6 flange that incorporates a 3D tapered exit port for a seamless transition to 1.25″ tubing. The backside of the flange has an o-ring groove for a positive seal without the hassle of Hondabond. This variant clears the VTEC spool valve assembly, and the outlet can be configured for standard hose (1.25″ OD) or -16 male flare.

NOTE: The cap bung has a 1/16″ NPT port for connection to an overflow and uses early model Honda radiator caps, such as an 88′-91′ Civic/ CRX or 90′-93′ Integra. If you are using AN lines, I recommend designing the upper radiator hose with some droop/give so the engine’s movement does not push/pull on the radiator and fatigue any parts.

The swirl pot includes two M6 socket head bolts and an o-ring. The tank is welded so that it sits level when bolted to an engine leaned forward 5.5° (exhaust side).
