ohm rating of injectors

[alanssaab]

hej alle , i have a 1989 t16s with the cream topped injectors which are 17 ohm , i have a set of red tops from a 2.3 9000 to put in but i tested them tonight and the are rated at 13ohm
will these function ok ? or will i need to arange some sort of step down in the ohm department
undsklyde its not in dansker
my danish is still lacking

Hmm, we better learn you some more! Normally your injectors should be fine, but I have my doubts, because of the large difference in Ohm... I can redirect your question to another board, maybe you can give me the numbers on the injectors, I know a few guys who now a few tricks, that might be able to help you mate...
Let me know,
cheers,
Daniel.

Kunne det ikke løses ved hjælp af en modstand?...

[Saab-daniel]

Jo, måske, men der er også en forskel i reaktans... Altså hvor hurtigt spolen i dysen reagerer på input... Kommer herfra: http://powerpage.gjelsoe.dk/viewtopic.php?t=13058

hey alan

the injektors you have are the bosch 431 red top from an 2,3 l 9000 aero and they flow 352 ml. at 3,0 bar. an have a resistans of 12 ohm. they are okay to use in your c900 but you will need a new fuelchip because they will give too much fuel at idle.
remember that they are two beamed made for four valve heads soo they have to be directet in the right way.

Jakob, the injectors will go in, along with a fuel-chip from Mats anyway, so that should be ok... As long as they are not too different in reaktans, as it says in the thread I linked to... I seem to remember, that those injectors have been used before on other people's c900's, so I agree with the above

mange tak aller
i need to speak with mats now about a fuel chip , i might just stick with the 2 liter head just now and stick the 2.3 head in next year when i get around to porting and polishing it
