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. The answer is yes and this is the result of a customer asking me to combine the two and utilize the unused space behind the V1 swirl pot.

I start with a V1 RBB/RBC swirl pot, add plinths between attachment points, a billet spacer to separate the swirl pot and overflow, and a support bracket at the rear to help with the additional weight. 

The swirl pot 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 swirl pot and overflow tanks base and lids are billet and each hold a billet radiator cap bung and vented filler cap. The two tanks are separated by a billet spacer and an extra layer of material is cut, shaped, and welded between each connection point (plinth). The outlet can be moved to suit your needs but the most popular choices are listed. The outlet itself can be configured for either standard hose (1.25" OD) or -16 male flare.

I do not recommend this product for any kind of racing! Due to the weight and despite my attempts to beef it up at all connection points, the product has had a few failures for those that disregarded my recommendation. If you drive hard... purchase the swirl pot and overflow separately.  

 NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. 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 hardware kit includes four M8 stainless steel socket head bolts, a heater port plug, and a Genuine Honda gasket. The swirl pot is welded so that it sits level when bolted to an engine leaned back 15° (OEM position) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option. The overflow inlet is on the bottom of the cylinder and is a 1/8" NPT thread.
