well, the car was a Peugout 1.9TD IDI running about 210-220km/h or so on 5500rpm with his 11mm, it did broke, i thought it was OEM Bosch plunger. after 2km it did braek into pieces, also the 2sockets on the main shaft are broken. i saw the pic's also, it broke simular to named tintin his last pump failure.
the 11mm was maxes out on the quantityscrew with a gt2256v

I lost an 11mm bosch pump head..over reving it..When I took it apart I noticed the plunger springs were much stronger.

A possible solution...would be to use 10mm springs on an 11mm or 12mm pump head for high reving. It would lessen stress on the pump head and I doubt the plunger would "float"

the springs need to be toghether with the camplate, otherwise the rollers will damage the camplate or the camplate will damage the rollers, alltough sometimes when its just a little difrence there is no problem.

@SMOKEYDUB: do you do 5800 for long periods or only in low gears?

i have done 5800 for a while but due to headgasket explosions i didnt hold it for more then a minute ( actually it was dr.diesel driving) It was in 5th around 200 ish with the diesel transmission. I should be able to go faster with a gas tranny.
