Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Torque Converter, Nitrous Holeshot, 2,300-2,500 rpm Stall Range, TH400, TH350, TH425, TH375B, Each

Nitrous engines produce some serious horsepower and require a serious torque converter to handle it. B&M nitrous Holeshot torque converters can handle up to 650 hp and are built with the same features as the other B&M Holeshots, with the addition of anti-balloon plates that allow these converters to stand up to the instant horsepower that nitrous delivers. Converters with higher-than-stock stall speed let your ride accelerate better from a dead stop and allow the vehicle to idle better when a big cam is used. Fully furnace brazed, heavy-duty, needle-bearing thrust packages and new turbine hubs are the key features of these converters, along with the anti-balloon plates. These are serious converters for serious street performance cars.
