Back on the dyno! After the complete rebuild of our Jetta’s BPY engine, we’re taking it to the next level with Paul. This time, we’re installing a series of upgrades dedicated to the nitrous oxide (NOS) system to push the limits and, hopefully, avoid an explosion.
The New NOS Modifications for the Jetta
Our preparation for the drag strip is intensifying with the addition of three key components. The goal is to gain power, but above all, control and safety.
A Progressive Nitrous Controller
First major upgrade: installing a progressive controller. This electronic unit allows precise dosing of nitrous oxide injection, preventing a too abrupt supply that could damage the engine. It’s the key to a controlled power increase.
An Upgrade to the Fuel Supply System
To accompany the NOS flow, an additional amount of fuel is essential. Therefore, we’re reinforcing the low-pressure system with a new pump and more efficient injectors to maintain the perfect mixture and avoid a lean mix, which is a source of detonation.
A Purge Valve for the Spectacular Effect
And for the final touch! We’re installing a purge valve. Beyond its spectacular visual effect with its white cloud, it ensures that the gas arrives pure and immediately in the engine upon engagement, for optimal responsiveness.
Final Goal: Back on the Drag Strip
All these modifications serve only one purpose: to return to the drag strip and break records. Is the rebuilt engine strong enough to handle this additional power? That’s the big test. Stay tuned to find out if the Jetta will explode this time… or if it will steal the show.
