Pico injectors - need advise...

[cliokongen]

Anyone got experince with Pico injectors?
I believe the 182 comes std. with Pico Injectors (xx cc/min)
- Quality
- Price

I would like to change my 305cc/min Bosch injectors for similar Pico injectors as they are physically smaller in size (lenght).

Online injector flow calculators indicate that i need (imo) quite large injectors (380cc/min) to reach 230 bhp.
According to these online injector flow calculators the 305ml injectors i currently use will not flow enough to to give the bhp result i have now (220bhp) - so.. i am a bit confused.

But in all honesty i must admit i have no idea of the max duty cycle used for the injectors in my current engine map. Might be more than the 80% most online injector flow calculators use...

I have been looking at these 330cc/min Pico injectors - i believe this is a good price.

Need advise regarding the size to buy, and info regarding quality and price....

I put 346cc injectors in wobbas engine, and they were running at exactly 80% duty cycle at 221bhp

I can highly recommend megane 225 injectors (480cc) for a pico fitment. They have excellent atomisation, and as long as your ecu gives you good resolution control they are not too big to be accurate at low revs. approx 55% duty cycle in snowmans car.

Excellent advise - tyskland Danny.
I bet my injectors are maxed out..... ;-/

What is the Renault part number for the Megane 225 injectors?

If you know what the megane 225 ID code on dialogys is I can look it up for you :wink:

Scrap that idea I've found it on evilbay :P 82 00 511 099

In fact that listing is by my local dealership :shock:

wankers! :evil:

[cliokongen]

thanks.... ;-)

Small world really - i found that exact listing and wanted to have the part number confirmed.

Is that dealer a Renault dealership? Hmmm.....

Michael

[cliokongen]

Hmm....
Megane injectors are definately an option (only problem is the the Ebay dealer will not ship outside UK)
Anyway 480cc/min is quite large :D
Danny - do you happen to have info regarding the spray pattern of these injectors?

Found a different size Pico fitment injector.
With 377cc/min it should deliver enough at 3bar/80%duty cycle to give 230bhp

Only thing - i am a bit worried about the spray pattern. 24deg. spray cone seems large? How will that effect the atomisation when hitting the side wall of the TB and manifold - positively?

Sort of, most dealerships over here are franchises that cover more than just 1 manufacturer. That particular listing is by co-operative motor group & the local Renault dealership is also a Fiat and a Nissan dealership owned by co-operative :wink:

Called them wankers because of my previous woeful experiences of getting parts from them leaving me stranded on a couple of occasions :evil:

[16v_paddy]

The next nearest Renault stealers to me is owned by a different franchise company :wink:

[cliokongen]

Thanks.... Good to know.... Stay clear of wankers! :D
