Joe-

The part# (both Porsche and Bosch) and location are printed on my torque values spreadsheet (not sure why I put them there....)

Dunno exactly how long fuel pressure stays up, but the pressure gauge on the stroker bleeds off overmaybe 30-60 minutes (?). Will check next time I stare at the engine for an hour after shutdown.

OH I see what the laugh is, but my fuel pressure has been over the zero line after 6 hours past shutting the car down. Now, the other pressure I would have seen a doc after 4. At least that is what the commercials always say.

4 hours max and then it's truly a medical emergency, but you do NOT want to see how they 'cure' you at the ER....

So it's not a group of nurses giving bjs to release the pressure?

Based on what Rob said I would guess it either involves a large bore needle or shudder to think "slice".
Okay all the guys can sit back down now from the jump up at that thought.

18 gauge needle. Sometimes the sight of it cures the patient right then and there.


Headers are on, spent the morning re-tuning. Pictures at 11.

WSM states fuel pressure should remain at 3 bar after 20 mins of engine off (24-211).

Front and rear fuel dampers are different:

930 110 602 01 rear
928 110 202 01 frt

Values printed in the WSM were stated before public access to the 6 hr issue that Jeff has..............good luck with that
