11mm bosh pump questions

[Dicky]

Just winds me up people wanking over 9mm pumps and then people fitting 9mms and then wondering why they're crap...

JPs 209HP he completely admitted was absolutely ON THE LIMIT of the pump and turbo... You wouldn't want to run it like that for any time, injection length too long, turbo getting raped, he didn't know EGTs but I wouldn't have liked to have known, guaranteed 1000*C+ though...

If you want to retain "stock" driveability, fair enough, stick with 9mm and they're good for 160-170HP ish, but the power won't be at 5k... But lets face it, "STOCK" driveability is pretty wank, you want the car to feel a bit more alive, more rash, more responsive, more eager... Hence 11mms will ALWAYS be better if you're actually pushing an engine...

Look at the 1Z TDis, they run a 10/11mm as STOCK on a 90hp engine to reduce the injection duration on an OEM engine... They go 12mm+ for high power, just to keep durations and EGTs down without slapping on loads of advance to compensate.

Ah I see, think I'll have to do some more 11mm reading and get rid of my 9mm when I finish drilling the bolts out and retiming it.
