    Unhappy Injector dynamic flow test results...

    So I decided to have my Bosch injectors cleaned and flow tested just to make sure they were healthy.

    Static flow looks good, within 1.2%, but dynamic flow is looking rough, I guess, to say the least.

    I would hate having to trash these since they aren't exactly pocket change items. I ran them last season without issues, 65 hours or so on them.

    Same reason I rather buy from a place that would have them flow tested prior to shipping them not all flow the same and some places have them flow matched for consistency.

    As far as cleaning (or to improve flow), how do they go about that? Just curious

    I guess but I've seen flow matched set paper work that went by static flow which in my case wouldn't be bad at 1.4%

    Interesting that these only managed to flow about 850cc but are rated 970 at 43psi.


    Does anyone know what RPM range different pulse widths would be use? I believe 2.5ms would be around idle.
