I read so much DON`t touch Pressure regulator(regulating valve is OK),but I don`t have cage for govenor mode.As I see if turn off like 1/4 Pressure regulator can I made same.I am not for speed just to see 2nd half of pedal,Like flyweights will cut latter or it`s mess with pressure.If it`s need- NA, idi motor.Best

if you made more sense, someone would answer. but ive never heard of governor mode the pressure regulator just sets the internal pump pressure, and ignition advance. you dont want to mess with the pressure regulator unless you have an internal pressure gauge for your pump.
what part do you call the regulating valve? ive never heard of one before.
cage for governor mode? meaning you have an uncaged governor spring?
the only way to mess with the governor is doing the gov mod. messing with pump pressure will do absolutely nothing for your governor, besides un-calibrate your injection pump.
if you cant use the second half of your pedal, something else is wrong, or else your max fuel screw is way far out.

Hi it`s must be my english,I call Pressure regulator one with flyweights on him 2 cm from regulating valve and by spend lot of time on this Best forum I made an internal pressure gauge (35 psi),and Yes I have an ucaged governor spring and my
Bosch dealer say NO different springs for that(0 460 494 189).
I have full pedal in 1,2,3 gear but 4,5 limited by pump on it`s 2200 rpm I think,so I just want to feel full pedal when I need but don`t know how.
-
ok, the pressure regulator is the thing right next to the fuel inlet of the pump.
the thing you call the pressure regulator, is actually the governor.
the spring that goes from the throttle lever to the governor arm, is the governor spring. VW's have caged springs factory.
and you will need more than a 35 psi gauge for internal pump pressure. i think they get like 150 - 200 psi at higher rpms.
possible someone swapped an industrial engine and pump in your car?
-
Sounds like he is losing power in the mid upper range and want to do the governor mod but has an uncaged governor spring.
I can't imagine an uncaged governor spring, Got a picture?
Make sure the accelerator lever is making it all the way to it's stop,.. sometimes the cable is adjusted poorly.
-
Like Cummins?
(http://i290.photobucket.com/albums/ll276/1stGen545/HPIM1787.jpg)
But the gov operates the same regardless of gear, speed, or load. ie. a 2500 Governor would limit neutral rev to that RPM as well as 5th gear.
If there area only problems in high load, high gear conditions, I might look for fuel restriction or air suction.
35PSI internal pressure as measured at what engine speed?

you guys catch all the red over spray in that pump? lol..

Hello
I have 35 psi on idle only,accelerator lever is making it all the way to it's stop chekd also,clear line no air.
Yes Fatmobile I losing power in the mid upper range in 4 or 5 gear mostly but it`s about 12 years I think it`s normal while I read your post about govenor mode and I am jealous little,help on this please.
-
I think 5-10 more psi at idle would get you closer so spec, it's hard to know without knowing what your idle is at.
So does your governor look like the one in the picture? If so I think you can get a stronger spring for it but you can't let the dealer know what car you have, they'll try to tell you "it's not for that car" find out which pump/vehicle takes the stronger spring get one for that.

Thanks man,it`s eazy too put 10-15 psi(even I afraid little of 45 psi on idle) and yes my governor is same as pic
that is why I ask about turn off about 1/4 flyweights rod.By " Tintin" on http://www.vwdiesel.net/forum/index.php?topic=7074 (http://www.vwdiesel.net/forum/index.php?topic=7074)
"For adjust the governor shaft, that depend if your pump is equipped with the system '' load dependant ''
If your governor shaft is like that of cummins, it do not need adjustment, the internal pressure of the pump is always to the maximum in proportion of the RPM
On the other hand, if it is like that of VW, the internal pressure of the pump varies according to the position of the accelerator, to adjust it, run in 4 gear, adjust turbo for low boost, and pushes on the accelerator gradually and you will ear the noise of the engine to change at a certain point, adjust for the ¾ of the accelerator"
Mine is like cummins.Best

cummins pumps are not the best application for our cars. not even close. i would take a modified caged VW governor any day.
-
ROR, have you ever driven an un-caged governor vw?

Come on guys,anyone help about turn off little to get just little more rpm.Best
-
I've never seen a governor spring that wasn't caged.
Not sure how to mod it for better power in the midrange.

never driven a CAR with a un caged gov. driven bigger things with them tho. the biggest reason im all for the caged governor, is because it comes stock in my pumps, and it is way easy to modify.
