Mine seem to be 1680cc each

Bosch part number- 0 280 150 846

I knew they were meant to be 1500cc ones, but didnt know the make (come in a "Ford Racing" box) till now theyve arived, or that they were grey, obv.

At least I know they Bosch ones now, so all that "I wouldnt buy them injectors from the states, they junk with very unequal flow rates, get bosch ones instead" stuff seems to be unfounded.

About 125quid for 8, new, happy days

 

eh whats this?

i've just bought some new bosch greys from the states, unequal flow rates

sent em to phil for checking, 65cc, 66cc, 66cc, & 68cc

says thats all fine tho

 

thats fine, cc out, but phil was saying a lot of non-bosch american injectors are absolutley MILES out, like dangerously so.

that might be bosch sales speak or bullshit, but thats what he said.

but these are bosch, so dont matter a toss.

just come in a flashy ford racing box

 

These look ok for a cossie potentially:

stav thats bullshit what there saying i get injectors reguair from states and i get tested at pj motorpsort and there alwys fine

 

thats phil for you then

 

thats bargain £125 for 8

what are these going in? take it there a lot bigger than 803 greys

 

no mate i get semens and delpy injectors and there are always fine and cheap aswell

 

about 3 times the size, and twice as many of them, lol


Stav has ordered enough fuel injector flow to cater for about 2500+bhp there!

 

so could i use a set of siemens instead of the bosch grey 403's

are they better, more reliable?

 

lol, what are they going in? a bus

 

Pretty much

Seriously tho, dont need that big an injector by a mile, but it means I got room to expand if I buy a Dart block in the future...

 

If you are running 400bhp or there abouts, a set of greys is a VERY reliable option.

 

My greys are about 2" tall and 1cm diameter

 

the old type grey injector is a bit of a dinosaur has a very large pintel the 83 lb semens is alot finer even thow it flows more karl got my co down to 1.26 for the mot with out closed loop wired up as karl dont agree with it as it causes excess heat on cooling down laps on track days
its cheaper to get 1000cc injectors and check them out than it is to buy a set greys

 

It's fine having such big uns but mapping becomes a nightmare.

Excess heat..... well that's a whole different topic on its own....

 

a car running on a very weak closed loop map will run hotter than a none lambda if the map is richer low down
so bring your car to low rpm after giving it large at 8000 plus for 20 mins will not do it no good well thats what i been avised
back to topic

 

Brom, leaner mixtures burn hotter yes. But the heat is NOTHING LIKE what the engine is getting on boost - it's negligable so will still cool down significantly. I understand the thinking behind it, but when it comes down to it it's going to be a negligable difference. I'd rather run lean for a nice clean engine. Carbon deposits on piston and valves from a rich mixture causing hot spots are far more dangerous!

But yea, back on topic lol.

 

i know very well what diffent mixtures do to temps and i also know what boost does to heat

 

Where's Mr-Ford when you need him
