TracTuff PRB/ PRC 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 "can you make a clean combo" or "can you make something attached so I don't have to run a line elsewhere". Enter the modified version of my V1SF  swirl pot, moved back a bit, so the overflow lines up with a mounting point at the rear of the cylinder head 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 has had mixed results. 

Like the V1SF, this swirl tank also starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint, a 1/2" NPT water bypass port, and machined o-ring groove for the OEM gasket. You can choose to have a 1/8" NPT sensor port added directly to the top of the neck (near the logo) or the side (under the outlet) as well as configure the outlet 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 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 the overflow and uses early model Honda radiator caps, such as an 88'-91' Civic/ CRX or 90'-93' Integra. The overflow port is located on the bottom of the tank and is 1/8" NPTF. 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 a 1/2" NPT to 5/8" water bypass hose fitting, a stainless hose clamp, a 1/2" NPT plug, two stainless M6 socket head bolts, and a Genuine Honda gasket. The tank 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 intake cam sensor must be swapped out for the angled (points up) version found on the K24's.
