TracTuff RBB/ RBC Swirl Pot & Overflow


One of the most common questions I get with swirl pots is whether or not an overflow is still necessary. Once I have answered that... it's followed by a "can you make a clean combo" or "can you make something attached so I don't have to run a line elsewhere". That's how this product was born.

Essentially a modified version of my V1 RBB/RBC swirl pot, moved back a bit, so the overflow lines up with a mounting point to support the additional weight. Due to the additional weight... I strongly urge those of you that race competitively, NOT to chose this product! The product has been used in harsh environments but it has had mixed results. Also, the original heater port on this flange cannot be used. If you absolutely must have a heater core connection, send me an email. 

Like the V1, this swirl tank also starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint and a 1/2" NPT heater port. The outlet can be moved within a range of 5 o'clock to 2 o'clock but the most popular choices are listed. The outlet itself can be configured for standard hose (1.25" OD) or -16 male flare.

 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 or options... PLEASE visit the WHATS WHAT or FAQ page. 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 line, I 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 Heater port but comes pre-plugged. As of 8/1/20 now includes a Genuine Honda gasket. The tank is welded so that it sits level when bolted to an engine leaned back 15° (OEM position).
