Injectors

[skini]

What are the spec(max hp) of injectors from Clio 1.4 16v??

 

[skini]

Anybody? Can i run 140hp with these injectors?

 

[theduck]

how you getting your car to 140bhp?? dont know about the injectors but thats a big increase!

 

[clio__chris]

benR is probably the man to talk to

i would of thought it would be alright tho

 

[Fred@BTM]

get us the details of the injectors

if you look closley at them you will see some markings on the injector plug

IWP 042 for example (172 injector)

 

[skini]

car isnt at my house at the moment. maybe someone else knows details? if not i will look at ti for few days.

so i dont have to take injectors down to see this markings fred?

 

[skini]

ok, a was told that the injectors are: IWP 026. this is not confirmed info. so fred what about this 026 injector?

 

[Fred@BTM]

let me find out

 

[Fred@BTM]

ok for comparison pruposes (1.4 16V Vs 172/182)

Static Flow Dynamic Flow

IWP 026 2,10 3,85
IWP 042 2,83 5,35

spray angles are different too

i have no idea what those details mean, ask BenR

 

[Fred@BTM]

i think Static flow is at idle (g/s) and Dynamic flow referrs to "weight" of fuel injected per pulse in (mg)

great. thnx fred

Static flow is the amount flowed by the injector at 100% duty.

The stupid rating of g/s (grams/sec) you have to convert into cc/min.

The measurement is taken at 3 bar from those data sheets.

So find out the g/min, then convert to volmume from mass by multiplying it by the specific gravity of the liquid.

Simplified thats 2.1x60 = 126 x 1.46 =183cc/min

To find rough bhp rating for the engine, divide the cc/min by 5 (for a rough bsfc of 0.5) then multiply by the number of injectors/cylinders you have.

So thats 147bhp at 100% duty.....more accurately, at 80% duty you can safly run 117bhp. you can run more than that and probably hit 140bhp, but itll be maxing the injectors, so youll want to pickup some off a 172.

oh and BTW GDI and i think Angel Works have a few spare 172/182 injectors for sale
