Volvo D24TIC Power issue
« on: February 07, 2020, 05:47:03 pm »
Hey everyone!

I have volvo 940 with a vw 2.4D R6 engine.

Recently it has a bit of a weird lack of power at full throttle in 3rd and 4th gear at 3000+ rpm ( when the boost hits 1.1bar ), but not always, and the engine is making weird noises when it happens, rattle or something, i dont know how to describe it in english, it sounds like it's it's timing goes retarded or has a lack of fuel or something.
I have new fuel filter (driven about ~1000km) and intank fuel filter is clean.
Today one time rpms dropped little a little bit at full throttle and then it was going again after like 2 seconds without any problems, seems like the problem is in 3000rpm area or something.

Any ideas what would be wrong or what to check? :(

Mod's i have done:
Straight pipe 2.5" with simons resonator
Modified boost pin and turned all the way down.
Governor mod, shimmed the spring 4-5mm
Injection timing 1.0mm
Max fuel screw turned almost all the way down.
Boost 1.1bar ( stock 0.8bar )
