Discussion
can anyone give me the part number, found on the side, of the 4.5 injectors?
it will help me with setting the fueling on the emerald, I have a 4.5 map, my car is a 4.2, and I have non standard injectors, I know all the specs for the 4.2 injectors and the new ones, but if I had the 4.5 part numbers I can get the specs for these and then change the map to suit.
hope that makes sense

No worries, I can look at the others and find their numbers if that one is no good.
if you can that would be helpful, I couldn`t find that number listed, the number looks like a lucas part, but didn`t match up with anything they had, if it was a bosche injector it would start with the number 0280.fatjon said:
that part number is 310cc at 3 bar with 12 Ohm coil just in case thats of use to anyone in the future.
Which incedentally makes them very borderline in a 420BHP car using the standard formulae. In fact they have a theoretical limit of 380BHP assuming they are not going over the 80% duty cycle. Although maybe the fuel pressure is higher than 3 bar on a Cerb, never had cause to measure it.high52kojak said:
I lent them to BGB for his crimpers car so i'll get him to find the numbers when he's finished dying his hair!!
Cheeky git, im going grey gracefully....Anyway, part numbers are as follows, (they have other less meaningfull numbers too which i can provide if required)
D1720BA (Had 4 of the 8 fitted in high52kojak's AJP8)
W097103 (Had 2 of the 8 fitted in high52kojak's AJP8)
D1720CE (Had 2 of the 8 fitted in high52kojak's AJP8)
Fatjon, it would be interesting if you could check the flow rates on these to see if all eight are the same.
Slightly off topic, will these fit a speed six
I have extensive lists but I can't find W097103 anywhere. I think on the others the last 2 letters are grades to allow selection of matching injectors when allowing for manufacturing tolerances hence the tiny difference in flow rates, they are effectively the same injector but should be in matched sets ideally.
Now I think about it that number (W097103) rings a bell faintly. I suspect its actually the part number of the connector on the injector. On the opposing face there may be another number which is the true ID number.

jon, on your lists can you tell me what these ones are good for, the injectors that came with the engine which I assume are standard 4.2 injectors are, 0280-150-744, and the new ones that I purchased from a chap who got them for his cerb but never used them are blue in colour and have these numbers on them, F5DE-B5A, 0280-155-715.
Looking on here, http://users.erols.com/srweiss/tableifc.htm#BOSCH these numbers show that these injectors I have will be no use at all for decent bhp.
here is a pic, new ones in blue, what I think are standard 4.2 ones on the right

0280150744 260cc/min at 3 bar 15 Ohm these are good for about 340BHP (assuming 8 of them) a tad more with higher fuel pressure and assuming a BSFC of 0.48 or 400BHP if you assume a BSFC of 0.4. Usual BSFC figure for a NASP engine is 0.4 to 0.5. A Very efficient engine is 0.4 so 0.5 is probably nearer the mark as an AJP is not noted for efficency.
the 0280150715 is 192c/min at 3 bar 15 ohm. Thats way too small for an AJP probably in the region of 240BHP at BSFC of 0.5 or 295BHP at BSFC 0.4
All the numbers assume 80% duty cycle which is the general standard used.
