Max fuel pressure for 0280 150 945

[Richard Wakeling]

Hi all,

    Finally completed a Delco conversion on a Porsche 911 (previously
K-jetronic) running 11 lbs boost supercharger.
Its running lean on the race track and I have been scratching my head.
Fuel pressure on boost from a rising rate FPR is just on 400 kPa.
    Does any body know if running 4 bar (400 kPa or 58 PSI) on the Bosch
0280 150 945 red 30 lb/hour injectors is too much fuel pressure.
    These injectors have 4 delivery holes and I would assume to be of
the rotary type injector. I have heard that too much pressure can be a
problem with rotary injectors compared with pintle types.

TIA

Cheers Richard (worried)
