Hi all can anyone tell wat these injectors are this is the part number 037906031d
G60 Injectors
Hi mate do you no wat cc they should be
315cc
Hi mate that's one of my problems I'm running the stage 3 ppp chip with r1charger bigger intercooler g60 pulleys and injectors I should be running the 250cc injectors and 65mm pulleys not g60 one's
G60 injectors are 250cc
An running g60 pulleys never seen or heard that one before! Any piks?
The part number on g60 injectors come up as 315cc and the set up on a g40 you can't use g60 pully I think you mean small pulley like 65mm , if the injectors are more cc than needed it doesn't matter as long as the map in the ecu is set right so if you have 315cc and only use 250cc that's fine it's better than maxing out the injector ,
Hi gas I'm not sure how to put pics up but I'll try and get some up later I didn't think g40s ran g60 pulleys but the person I got the car from said that's way it has got my mate 65mm pulleys are bigger than mine
With all the mods my car has it should be 165bhp but it doesn't go like it my mate's standard g with 65mm pulleys whoops mine all day long
Just a thought wouldn't the g60 injectors put more fuel in than the 250cc so I'm probably over fueling
The map on the ecu tells the fuel pump how much fuel to use so if it's mapped for 250cc and you have 315cc it will only use 250cc out of the 315cc tolerance ,

Utter bollocks! If you use injectors larger than the map is intended for, it'll overfuel with the risk of bore wash and premature engine wear. If you use injectors smaller than the map is intended for, it'll run lean with the risk of melting stuff. The ECU has no idea what size injectors you're using, the only feedback on the air/fuel mixture it gets is from the basic narrowband lambda probe which it only uses at partial throttle. On full-throttle the ECU doesn't use this feedback, so opens the injector for a pre-determined amount of time determined by the map tables - it has no way of knowing at this point actually how much fuel it has injected, nor what the air/fuel ratio actually is, so it cannot correct for people putting the wrong injectors in.
037906031D is the VW part number for G60 injectors. The Bosch part number is: 0 280 150 905 - that should also be printed on them.
If you use the resource on this site with the Bosch part number it'll tell you that you have G60 injectors, at a flow rate of 250cc/min (or 255 in this table):

Theres also some blue 250cc injectors that people had in from a ford i think and they cause trouble!
But listen an take note to andy he knows his onions lol
I should stop posting sorry just going on what was in the discripsion of my last polo he said in the post witch every body can still see, :-X (better injectors fitted. (green top, blah blah, whatever...) they still inject the same amount.. just in the middle of their tolerances, rather than maxing out standard items. i think they may even still have the silencers fitted to them (surprising how much of a difference they make), I'm an idiot for going by that,

Andy you can slap me when I meet you for a remap
What Andy said
helped me out when i found out my car had g40 injectors and a chip for g60 injectors
was running mega lean causing some severe pinking!!
Also saab injectors are the 315cc ones
250cc g60
200cc g40
