VN/VP Fuel Flow Rate (Stock injectors)

[needwork2-4fillhabbit]

As the title suggests, im looking to find out what the original stock injector fuel flow rates are for vn/vp commodores. Help very much appreciated.

ur best bet would be in the VN/VP Section :thumbsup:

I think the injectors are around 18lbs but i want to know the fuel pressure rate. (oh and thx for the move lol swore i posted right..)

 

[cracker]

its got a 3.0bar regulator if thats what u wanted to know

May be easier if someone has the part number or bosch equivalent so i can suss it out. Heres an example of what im after:

Static Flow Rate: 28 lb/hr (294cc) @ 43.5PSI (300kPa) These are from LS1 injectors.

I really wanna see what difference the vn/vp psi difference is.

 

[PaRaDoX]

18-19lb @40-43psi

i think they're round 186cc?

not much thats for sure.....

try and find a good set of 706's (88/89 EFI magna injectors) same as the group A but that requires a injector flow rate change in the ecu (kINJFLOW function)

pretty much they're suited to a stock motor and dont support big hp

injectors

VN series 1, 8-88 to 10-90 uses injector number 0280-150-901 which flows 146.3 GPM @ 3 BAR. Resistance 14.5 ?.

VN series 2, 11-90 to 10-91 uses injector number 028-0150-960 which flows 150.5 GPM @ 3 BAR. Resistance 14.5 ?.

These injectors are also fitted in the
VG UTE 11-90 to 10-91, VP COMMODORE 11-91 to 07-93 and the VR COMMODORE 06-93 to 04-95.

VT - VY N/A, 09-97 to 06-03, uses injector number 0280-155-777 which flows 150 GPM @ 3.5 BAR. Resistance 12 ?.

The VN - VR injectors are what is classed as an EV-1 injector pintle type which are open to problems when used at an incorrect fuel pressure, hosing is a problem if pressure is too low or too high and the pattern can also be forced too wide for the target area if pressure is too high.

VT - VY injectors are what is classed as an EV-6 injector which uses a multi orifice director plate style technology to better atomise fuel across various operating pressures. These injectors allow more flexibility in relation to operating pressures without compromising spray efficiency or fuel atomisation.

Im curious as i have 8 brand new #12561462 injectors rated as an earlier post there 28lbs. But i think for 10-12 psi there going to be a little small. So i guess ill sell em or swap em at the wreckers. PM me if you need some. Sure there the EV6 ones you mention.
