Are deatschwerks bad injectors too ? Because I've only heard good things about them, and you get them with a flowtest chart and all... I thought they were brandnew injectors ?Originally Posted by Ben
if youve got 660's then theyre quite overspecced which is why they could be working fine
personally id never trust reworked std injectors...that goes for venom/deatschwerks and all the others out there. proper ones arent exactly expensive these days
run them in your car for a couple of months then get them flow tested and im sure the results would shock you.
damn
So what injectors should I go for then ? For an RB25DET S13 by the way...
get a set of nismos man!damn

there worth it in the long run
hmmmm...
I'll go check ebay then
Deatschwerks seemed nice and cheap...
These are the results from a set of brand new 800cc Venom/TLF injectors tested by Abbey
This was at only 2.5bar pressure. Any more and the results would be even worse.
Yup, Ooparts are great, nice prices and smashing service.
Impressive, car ready for JAE? Would like to see this beast!hahaha erm.....well the turbo has potential to 600hp
Nismo, SARD, Trust, HKS, Power Enterprise etc. Any of the good Japanese tuners will be good since they are extremely pedantic about everything. If you can find some german injectors or non-reworked injectors they should be fine also.
I have heard and read more bad things about them then good, however Jez has mapped on them and says that D-werks are ok.
wow didn't expect this reaction!
dont think i will go for them then.
just stick with the gtr yellaow tops i got sat around and up the pressure a slight bit if need be.
thanks for the info guys!
Can you overspec injectors? i.e. running 600s on a standard setup with the view to upgrading? Or would it cause too many issues?
You can overspec yes, but you will need a SAFC or a remap, as the bigger injectors will be flowing more fuel at the same duty cycle. If I read correctly, the CA18 batch fires injectors below 3800 RPM, after that it fires the injectors sequentially. This means that you can operate at a minimum of a 60% cycle. You sould not run injectors higher than 85% duty.
What power do you have? Stock? You can run 600's, but as above, you will need a remap unless you have a programmable ECU (and know how to program it).
Thank you for the information, very informative
No probs overspeccing if you're getting mapped, otherwise don't.
Old days, big injectors wouldn't dwell short enough to idle well, nowadays it's different.
Ouch. RC don't do 800cc injectors.do not by them beni got 800cc rc injectors from the us when i got them here guess what it sead on the box
VENOM!!!
I was bored so I created a quick spreadsheet that works out injector flow, and max power for a given injector set, I'm pretty sure its right (I am reading the Graham Bell books atm), but if it isn't, i'm sure one of the more knowledgable guys advise me on my errors!
Rememberthe static flow is based on the RPM point that makes that maximum hp figure, so its not required all the time since the engine is not making maximum hp all the time.

(HP x BSFC)/(No. injectors x max duty %) = lb/hr.
lb/hr x 10.5 = cc/min

thats depressing as i though rc was really good.........noz's post is interesting.do not by them ben
VENOM!!!
where did you get them from as it sounds like you may have been had
fwiw deatchsworks dont seem as bad and only use a small overbore unlike the venoms so they could be ok
I'm not a big ford fan but the RS500 is a legend, you cannot take away from it its Icon status and to suggest that its a chavvy car is like saying Kirsten Scott Thomas is a council estate slapper
RC does not = Venom
BSFC = 0.6-0.7 for forced induction? Cheers, i'll add the fields.
i had 4x 720-740cc Venom injectors, but they were to "good" so i had to switch to same size but Greedy ones witch runs perfect even at idle.
i would not recommend them, you get what you pay for.
