TracTuff PRB/ PRC Swirl Pot - V1SF

TracTuff PRB/ PRC Swirl Pot - V1SF


The OG! This was my very first design for the K series. The tank sits just in front of the intake camshaft sensor and now includes a brace to support the tank.

The swirl pot starts with my billet PRB/ PRC style flange that is machined from US milled 6061-T6 aluminum and incorporates the largest port possible within the OEM gaskets footprint, The neck comes standard with a a 1/2" NPT water bypass port and a machined o-ring groove for the OEM gasket. You can add a 1/8" NPT port to the neck to accommodate the OEM single prong sensor that gives all the early swaps the temp reading in the cluster as well as a number of options to suit your specific needs!  Choose from standard hose or AN hose connection, import or domestic radiator cap bung, bracket plinth (additional support) and a few different accessory bungs for things like temp, pressure, or turbo/ waste gate feed. 

The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic version uses any early model (late 70's Chevy C10 Pickup w/ 454) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at If you have questions related to the configuration options... PLEASE visit the FAQ page. If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. The billet neck has a 1/2" NPT water bypass port and the hardware kit includes a hose fitting and a plug in the event you don't plan on connecting a bypass hose. The tank is welded so that it sits level when bolted to an engine leaned back 15° (exhaust side).

1/1/19 Update: Due to the stress placed on the braces, from poorly plumbed upper radiator hoses, a plinth can be added to the bracket to help distribute the load and increase strength.
