Does anybody have the scaling informantion on them? I asked them and all he said was it was 43.5 psi and that gm base pressure was 50 psi so it would actually flow more.. Does that make sense to anybody?

 

No, that doesn't make sense to anybody.

 

Lol thats what i thought, he said its the same as siemen deka 55's

 

A buddy of mine just replaced his on3 injectors with Siemens deka because we couldn't get the truck to run good at all with the on3's. I would stay away and get a good set of injectors, fuel is not a place to try and save some money on a turbo motor.

 

Yea im prolly about to do the same, i just wanted to try and use the whole on3 setup to give them a full review

 

Injectors are useless without a reliable set of data.

 

Yea i understand that now, so luckily im in process if doin the turbo so i have some semein deka 60's gonna go in it

 

All he was trying to say was they flow 55 lb/hr at 43.5 psi so at GM pressure of 58 psi they will flow higher, but will vary some too depending if vacuum or boost is accounted for, especially in non manifold referenced FPR setups. That being said everyone is correct that good accurate data is very important for tuning, not just flow data but offsets, pulse width data etc..
