Does anyone know the flow rates and lag times of all the different cosworth injectors. Im mainly after information on the grey 403s but a chart with all the types would be useful.

Ive googled this but cant seem to come up with much
Thanks

tabetha

If you give me the FULL number of the greys, I can look them up for you.

tabetha, a while back i bought what i thought where greys, turns out they are are grey but not the ones us cossie users have, it seems to have a proper bosch number on, if i find out the number, can you find out the flow rates etc?

FEATURES of the 403 - GREY in color/colour, / Low impedance / Coil resistance 2.6 Ohms / Peak and hold type / common L-LE Jet 2 pin electrical connector / unusual ends / length dimensions as per standard EFI injector (65 mm c/c between O-Rings) / single pintle.
Flow rate - Charts show 503 cc/min (49.3 lbs/hr) @100% duty cycle, presumed at a pressure of 3 Bar (43.5 psi). USA based www.dune-buggy.com and others show a higher flow 55 lbs/hr @ 45 psi. (Feedback from P Bradley) -403 injectors - had them cleaned and flowed. At line pressure of 43.5 psi, they flow about 59 lb/hr or about 600 cc/min at 100% duty cycle, flat out. Wide open they flowed 114 cc after 11.4 seconds, and pulsed flow 102 cc after 21.2 seconds.

Cheers Rinus, thats very helpfull

Tabetha, the number on the box is 0280150403
Thanks

tabetha

The above numer 0-280-150-403., shows the following,
FLOW= LBS/HR 47.9, CC/MIN = 503.4, GRAMS/MIN 362.1
Rating 43.5 PSI/3 BAR, these are LOW impedance injectors fitted as standard kit to FORD 5.0i HO.
The listing also contains BSFC data, not really of any use.
NOTE:
THERE IS ANOTHER INJECTOR OF THE EXACT SAME NUMBER, which has different flow, but this is most likely due to a pressure increase, as the flow is higher.

lol the ones i got ripped off for on flea bay are 0-280-150-129

tabetha

Don't use them they are JAGUAR ones for 3.2/3.6, have way smaller flow as BSFC is totally different.
0-280-150-129 are,
191.3 CC/min, where as 0-28-150-403 are 503.4 CC/min.

i didnt, when i took them to Karl to be fitted, he said i dont know WTF these are but they are not greys. so bought some new ones.

i'll put them in the bin then, now that i know what they are

tabetha

Sell them on ebay for jaguar bits.
Nice to know someone does not give a shit about your engine going bang so long as he makes a few bucks out of you selling these!!
Hooray for KARL spotting that, could have been expensive otherwise!!
Were they the same colour etc as the "cossie" ones ?

yeah looked the same, but (hard to explain) but the nozzle (if thats what you call it) had the rubber o ring built in, where as proper greys, have an exposed end if you know what i mean?
