Boost pin for VW 1.9 TD and Opel 1.7 DTL 52 HRC engines

The only PIN on the market that has undergone actual heat treatment and been hardened to a hardness of 52 HRC.

The heat treatment process always causes a change in the steel’s color.


The part is manufactured on a modern CNC machining center using specialized tooling made of high-grade chromium-nickel steel.

PARAMETER SETTINGS. Why use the BOOST PIN?

LDA—this is a mechanism in the TD injection pump that limits the fuel dose at low RPMs and when there is no or low boost pressure. However, when the pressure increases, it automatically delivers a larger dose of fuel.
In the animation above, we see a pin—the so-called PIN reader—which moves to the right when the accelerator pedal is pressed, causing an increase in fuel delivery. However, it is clear that the movement of this pin is restricted by the PIN—this is the very essence of how the LDA works. The further the PIN reader can extend, the more fuel will be delivered

In the animation, we can see that the diaphragm’s PIN is not symmetrical; the notch on one side is larger than on the other. Thanks to this design, we can adjust the amount of fuel delivered when boost pressure is applied. By increasing the PIN’s notch on the reader side, we increase the fuel dose; conversely, by rotating the PIN so that the smaller notch faces the reader, we cause the reader to extend less, thereby limiting the fuel dose.
