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 email@example.com. 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.
