GTurbo CT26 Bad Boy Stage 1 + 1HD-FTE HDJ79 = over 200kW (at wheels! (1 Viewer)

Just wondering, what else have you done with the 1hz? Simply added a turbo? Or have you beefed up the engines internals to handle the added heat and pressure?

The 1HZ when tuned right is strong enough for great performance.

If you have a turbo that responds to the right foot when afrs get to the lower end off acceptable and in the low rpms, you can run high boost and retard timing slightly, reducing the mechanical load potentially making the engine more reliable.

In any case, the 1HZ can be very good. Also......, tuned wrong they can be very bad.
