Is your Barra a bit blocked up?
High-horsepower Barra engines need massive crankcase ventilation to prevent blown seals, but welding on fittings often means hacking up your engine cover or ruining the clean OEM look of your engine bay.
The Atomic Solution
The Atomic "Stealth" System. This is the only weld-on solution designed specifically to fit perfectly under the standard plastic garnish while delivering massive -10AN flow.
Zero interference: Fits under the factory cover.
Precision Jigging System included in every kit.
2. The Jig-Locating System
We removed the guesswork. Every kit includes our proprietary positioning jigs that lock into existing rocker cover features.
- Precision Placement: The jigs bolt or clip into factory holes, holding the weld-on bung in the exact coordinate needed.
- Foolproof Welding: Simply install the jig, drop in the aluminium bung, tack weld, remove the jig, and finish welding.
- FG Dual Jig: Includes separate jigs for Front and Rear fittings.
- BA/BF Single Jig: Includes a jig for the critical rear fitting (front is positioned visually).
3. Atomic x Speedflow Engineering
This isn't an off-the-shelf adapter. We partnered with Speedflow to engineer a bespoke extension fitting specifically for this application.
- Part Number: Z-MC-920-10-L-BLK
- Custom Low-Profile Design: Shorter than a standard extension, critical for clearing the garnish. Slim enough to fit the rocker cover garnish without cutting*
- Seamless Integration: Designed to mate perfectly with our -10AN ORB weld-on bungs.
- Australian Made: Manufactured to the same high standards as your engine.
