My 37# Racetronix injectors are stamped 40# on the cases. WTF

This is what I ordered from the Racetronix website:

Other than if you have already got it tuned for 37#, why complain? 
You could always go and get an AFPR then and turn them into 37#ers. I calced it quick and you'd need to run 37.5psi for 37.1#.

Have you made any effort to find out what pressure they are rated at???
Do you realize the 30lbs SVOs are almost 32lbs when used at stock LT1 pressures.
People don't bother to understand systems and that is why they have so many troubles and make such bad choices.

Maybe one day I will have your superior intellect along with the taste of AI's dick in the mouth when it comes to motors not to mention the desire to post useless BS that does nothing to advance the topic of discussion or help people to get a better understand of the systems you mentioned. Holy **** I cant believe you passed up the chance to rip on LE in my post and blame the injector ID problem on him too.
Every ******* time you reply in my posts its the same **** with you. You are so ******* full of yourself.
and stay out.I apoligize to everyone else who has to read my rant about 96capriceasshat.

Hence the comment on SVOs. They are not 30lbs in an LT1 but everyone calls them such because that is what they are marketted as. Pays to understand things.
They also test with a solvent that is NOT gasoline, gasoline tends to give higher readings than the test solvent. That information can be found right on their site, typical 3-4% higher flow if using gasoline.
Put it together and see what the BLMs are, that is far more important than the published specs on something allowed 4% variation, that is 1.5lbs variation allowed in a matched set, on top of the 3-4% lower reading cause by the solvent.
Ford stuff is rated at 39psi, LT1 at 43.5, LS stuff at 58psi and we can use injectors from any of thos applications.
To me that is critical to figuring out what injectors to use.
If the BLMs are in spec you are good to go, if not work it out with the tuner.

They have been tested and flowbenched extensively at different pressures. The result is always right about 30#s at 43.5psi.
Just because the fords they came in used 39psi rail pressure does not mean the injectors used the same when rated. Everyone just kind of assumed that, and continued to think that even after being disproved.
You of all people should recognize how hard it is to stop forum "data" from spreading even if it turns out to be less then factual

I thought that too back in 05.

Sorry to stray off topic even more, but here is some info on the SVO ratings debates.
Did a quick search and hunted down a handful of links, here ya go:
SVO 30#'s flow benched<-Guy recently flowed a set of SVOs and posts results
HUGE thread started in 05 <-This thread covers almost everything...tuning for SVO offsets(different drivers used then fbodies), scalers, pressure ratings, multipliers, etc...thoughts go back and forth as a group of people try to settle whats really going on with SVOS. TONS of good info(page 4/5 especially)...
Blog post by RedHardSupra<- He REALLY knows his stuff with injectors and fuel systems. Quick observation he made, and someone else "X2'd" his findings.
For those who like it visually:
^^^At 43.5psi the 42#s averaged a flow rate of 43#s. Well within normal tolerance range. Notice how they also show less of a flow variance between injectors then standard LT1 type injectors. Also, they hold thier spray pattern better at shorter pulsewidths then stock LT1 style injectors. Becuase of that, even if the same # injectors are used in an LT1, just those two traits make the SVOs worth it IMO.

The point that should be understood here is that the industry standard for rating injectors is 3 bar, or 43.5 psi. I hve seen a company that consistently rates their LS1 injectors at 4 bar, which is 58 psi. This is skewing the data and giving the impression that they are larger injectors than they are. For example, they are selling 36# injectors (at 3 bar) as 42# injectors for an LS1. While technically correctly, they fail to mention that the injectors are actually 36# injectors that run at 42# at LS1 pressure, which would be more ethically correct.
I don't know at what pressure SVO rates their injectors, nor do I want to be drawn into the discussion. But I don't know why they would rate it at a non-standard lower pressure, since it would actually make their injectors appear to be smaller than they are.

Puck, the problem with that first link, is that all those testings come out to be at what SVOs would run at if you assume their rated @ 39psi and then compensate for 43.5psi heh
"My least flowing injector runs 330ml/hr or 31.4lbs/Hr @ 43.5 PSI."
And the 30# @ 43.5PSI is... 31.6835#
The other thread, he mentions the Cobra owners and their 39# injectors "making them ful 42#", when they'd actually be 41.1#, which is pretty far off from 42# when you start talking the little gain from the PSI change.
Also, it appears MINE are 39.15PSI rated lol Bosch #0-280-150-947
http://users.erols.com/srweiss/tableifc.htm
This site backs up the above's claim.
http://saft7.com/?p=286
I googled and got a pic of them and they're my light-blue tops!
F1TE-D5A can be found here:
http://www.carburetion.com/Injector/injector.asp
Then again... they could be LIGHT-light blue :\ In which case they're 43.5psi rated heh Now I'll have to actually remember to check at some point in time lol F1TZ (I think they're the same as FMS/Ford Racing M-9593-A302 which you can see @ summit)
http://cgi.ebay.com/ebaymotors/_W0QQitemZ110344520050
So, bottom line? Don't listen to anyone except what you've found out yourself! (IE look up your injector's P# on both of those sites and make sure they both give the same "Rate @" PSI, then calculate from there!)
Hoh... here we go! "B-280-214-912 175.0#" lol
K Glad that's all settled haha
