I have som injectors that suppose to be Siemens 55# , but they look totaly different from the ones I allredy got . They have the number 8305 and 17113841 .. anyone knows.. ?

blodstrupmoen

Yea they are not Siemens but Delphis And seeing that they are 2ohm I might need som resistors aswell. I was hoping they where a direct replacement for my Siemens 55# as two of them are making a bit more noise then they should and that EGT is higher on that Cyl ..

You were running Siemens w/o injectors?

blodstrupmoen

I`m guessing you mean W/o resistors .. But yes sir .. And they have worked fine for 5yrs

Darwantae951

...oops...yes, I meant resistors I know they work without them, it just seems like cheap insurance to put them in and it wasn't that hard. Siemens are what, 2.5 ohms?

blodstrupmoen

Yes it seems like the Siemens are 2,5ohm ..Always thought they where 3 ... Well anyway took my siemens to a injector service workshop today and The guy there says that most likely they where running with too high duty cycle. hmm .. According to most people here @ the list that may not be the case as they should support 350rwhp .. But then again I`m not sure about engine output since last mods.. bet it`s not near 350 yet..

Darwantae951

55lbers at too high a duty cycle? What kind of boost are you running? What are your mods?

blodstrupmoen

Well .. official 16psi, ( but it`s usually set to 18 .. sorry John ) . Vitesse stage II w/ wasted spark, SFR stage II headers, 3" LR exhasut with Borla muffler, Tial 38 WG, light headwork .. just some basic that is.

Other than that I have the Zetronisk WBO , knock sense and 4ch EGT probes..

Darwantae951

And you maxed out 55lb injectors?

blodstrupmoen

Nope I don`t think so.. But that`s what the service guy told me..

I regret not getting delphis, in case I converted to e85 later on.

Measure it. You can buy a kit or use a dwell meter.

I've used them for 3.5 years...no resistors either. I think that Vitesse recommends 72's for the OP's set-up, if I remember correctly. I just inquired a few weeks ago about the same (similiar) set-up, and I think John said 72...let me check e-mail.

EDIT: Vitesse recommended 72's if I also use a larger turbo.

blodstrupmoen

yea I know .. I allready had the 55# so I did not bother @ the time . Anyway , I might get a re-flash and upgrade to 72`s during the winter.
