TracTuff P72 Swirl Pot – V2

Description

I one-upped the V1 for the boys at Whitfield Mfg. This new offering for the P72 (B18C1) cylinder head allows the use of a scatter shield, where the simple design of the V1 did not. Great for vehicles with tucked radiators, radiators without a fill point, or situations where you simply need a higher fill point to aid in burping the cooling system.

The swirl pot starts with a CNC-machined 6061-T6 flange with an added o-ring groove, so you no longer need to use Hondabond. This variant clears the VTEC spool valve assembly, but does not work with a scatter shield. The outlet can be configured for a standard hose (1.25″ OD), -16 male flare, -16 Wiggins, or Dyme PRO/SPEC (shown).

NOTE: When chosen, the radiator 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).
