24lb injectors

[SuperV8]

My 2 peneth:
I would go for bosch design III type injectors (EV6), These are the same size and fittment but use newer multi orifice design compared to the old pintle type. This atomises they fuel better across a wider fuel pressure range.

Extract taken from Bosch data sheet:
"Effects of Fuel Pressure on Pintle Type Fuel Injectors.
Fuel velocity through a pintle type fuel injector [type code EV 1] can dramatically
affect its ability to atomise fuel. The profile of the pintle used in a
fuel injector has a direct relationship to the operating pressure it is designed
to operate under. Whilst Bosch produce various fuel injectors that may flow
the same amount of fuel at a given specification, the system operating pressure
will influence the pintle profile. Correct pressure will result in a well
atomised spray, while insufficient pressure will result in a “hosing” effect.
Excessive pressure will result in either “hosing” or a spray angle that is too
large for the targeted area dependent on the pintle profile.
The consequence of excessive fuel pressure on a pintle type injector may
well be that as the pressure is increased the mixture values of the engine
may appear to get leaner. This is of course not the case, but the fuel being
injected is no longer atomised and is entering the cylinder as a liquid mass.
This will typically cause the Hydrocarbon [HC] values to rise due to the raw
fuel exiting the cylinder, and the Carbon Monoxide [CO] to drop due to
insufficient combustion.
Later design fuel injectors [type code EV 6] use “director plate” multi-orifice
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."


They cost similar to the older design but use a narrower plastic body compared to the fat metal one.

I have just brought Bosch PN 0280155968 green used on Volvo V70R's 42lb's. $50 each from the states.

Like I say just my 2 peneth,

[Coops]

i got my green motorsport injectors from ebay,
five-0 from the states on ebay did me a cracking deal,
will have to look up what it cost me again as had them 2 yrs now,
