Details
The Pro-Series 350BD-4 is a ‘dry’ system designed specifically for 4 cylinder, fuel injected competition bikes and manufactured to the highest possible standards. The unique concept behind the Pro-Series 350BD-4 makes it the most effective direct port dry system on the market.
The distinctive features of the Pro-Series 350BD-4 are;
1) Our unique use of Y-Blocks rather than a rail or shower heads to achieve perfect distribution.
2) The unique design of the discharge tubes, which maximise nitrous flow and eliminate the drawbacks of injectors.
Tests have proven that in all cases (when adding up to 350bhp) a Pro-Series 350BD-4 can outperform any other direct port dry kit, whilst being more engine friendly.
The Pro-Series 350BD-4 offers;
1) Superior performance at a very competitive price
2) Peace of mind due to reliably and effectively delivering the exact volume of nitrous oxide required, when required.
However, being a ‘dry’ system the customer is responsible for ensuring the ‘essential’ additional fuel is added to the engine for optimum performance and reliable results.
WON designers put great thought in to the ease of fitting and performance when developing this unique system.
