could you get a more full picture of the engine bay, kinda curious what all this stuff looks like
I'll get some more pics before too long.
That is a NA pump with a LDA like feature , it turns inthe fuel screw with boost pressure.
That idea kind of frightens me. :shock:
It might be frighening if it actually increased fueling :lol:
I have only driven a few old IDIs, but this one doesn't feel any faster that the last 1.5 NA Dasher I drove here at altitude, this one also doesn't smoke at all, ever, nothing. I gave him links to smog's "make your 1.9 TD faster" thread and a few others so he can add some more fuel and see what the boost does then. I was under the car today and the EGT probe is pre-turbine

but the highest he has seen it is 800* F, how hot do these run in stock form? And the wastegate is held closed fairly firmly by the actuator so that isn't the source of the low boost issue.
It is a NA block, so no piston squirters, but it seems like such a waste to have boost only come on above 3000 RPM (no tac, just guessing on RPM), and then it SLOWLY climbs to ~5 PSI, which is enough to make it not smoke at high altitude, but it sure would be nice to have that 5 PSI at 1,700- 2,000 RPM.
Dave, do you know anything else about this wanna-be LDA?
