This week's bargain...

[M-R-P]

Finally got a set of blues for £22 :shhh: I immediately got them home and fired-up the ultrasonic bath and after 15 minutes...

Just ordered a rebuild kit for a tenner so hopefully I'll be larfin' soon :D

Happy M-R-P :pimp2:

[JamesT5]

I've got blue ones on my T5, I didn't realise until I looked at the photo I took the other day......

http://i1306.photobucket.com/albums/s562/_JamesT5/P1010807_zpsb2a83f74.jpg

Mind you, I wouldn't know the benefits of other colours to be honest. Anyone car to enlighten me? :D

[M-R-P]

Well James... Mine SHOULD have blues but plod changed them. The colour depicts flow rate.

Orange (mine) is the lowest, then white, then blue, then green, the NA models have different injectors.

[volvokid]

Nice how did you get on with the bath

Nice price,so what's the flow rate difference of these ones.

[M-R-P]

Nice how did you get on with the bath

Went in 3 bouts - 10 minutes with some hard core degreaser which pretty much cleaned the outer casing.

10 minutes with mild soapy water, on a higher frequency to loosen the crud off the inside.

Used a home made rig to pulse the injector to clean the chamber and a 5 minute buzz just to finish it off. I'll run some mineral solvents through them tomorrow to flush them out properly.

So sounds like you average MPG is going to drop a bit.

[M-R-P]

78cc more with the blues ;)

[Harvey]

78cc more with the blues ;)

Nice.

[M-R-P]

So sounds like you average MPG is going to drop a bit.

Shouldn't - once the ecu learns the new flow rate it'll adjust the duty cycle accordingly. The problem I had with the oranges was they were maxed-out causing the engine to run lean. That and the oranges had lottery miles on them lol.

[M-R-P]

Pinched from elsewhere...

Most of the 850 Turbos used orange injectors which flow at 310cc.

The 98 R and T5 had the whites which are 350cc and in 99 the blues were used on the R and possibly the T5 as well. They flow at 395cc. The greens are a 00 R thing and flow at 465cc I think.

[Kingsford G]

Niced work mate.Did u have much crap out from the inside?

[Dangerous Dave]

Just a bit of extra info.....

Blues flow the same as whites at 3 bar fuel pressure (347cc). What Volvo did was increase the fuel pressure to 3.8 bar to up the flow to 391cc. The only other difference is blues are 12ohms impedance and whites are 16ohms.

Interesting, thanks mate. I take it my car runs 3.8bar?

This would go some way to explaining the shortfall in torque in the last RR session, and probably the massive detonation I got on the first RR session :(

[Kingsford G]

U should get more power now but still less than me :hidesbehi

[V70 Graham]

U should get more power now but still less than me :hidesbehi

.....and me lol, well done on the bargain though mate.

[Dangerous Dave]

It would go some way to explaining it i'm sure. Also the oranges will be a higher impedance so that might have had an effect too (if only slight)

Not sure on your fuel pressure mate, but guessing it is 3.8bar. So they will have been flowing a bit more than 315cc but certainly not what the ecu 'thought' the flow was.

Might be worth resetting the ecu, on my M4.4 ecu I'd just unplug it (for a while) to reset the adaptions, but not sure if it can be done on the ME7, someone will know.

Well done on finding a bargain matey :D

[M-R-P]

I pull the negative on the battery every few months or so and yeah, it resets the bit of the ecu that remembers your driving style. Makes it less aggressive but more efficient in my case lol.

I'll be pulling the battery when I fit the blues :)

[Dangerous Dave]

Cool, glad it can be done without taking it for a mortgage session with the local Volvo dealer :D

[Wobbly Dave]

Well I put in the ASNU 650cc injectors. Ran like a wounded dog - but within 20 minutes the ME7 map adaption had it running fine on idle.

[M-R-P]

Say what you like about ME7 but it has it's uses, ay Dave ;)

[silverhorse]

HA! The car thinks,'thank God I have a new driver', then after a few miles realises, 'bugg3r, its still him'!!

[Dangerous Dave]

Haha :D :D Love it

[mitchyboy01]

It may adjust in closed loop (idle, part throttle) using the lambda sensors but the ECU cannot adapt when in open loop i.e WOT. In open loop (using MAF values) the fuelling runs off preset maps which can only be altered by remapping. You will get away with it as they aren't hugely bigger injectors but the fuelling will be richer at WOT unless you adjust fuel pressure accordingly.

[M-R-P]

Car is supposed to run blues but is currently running orange and runs lean.

I predict it'll run perfectly ;)

[p fandango]

you got a bargain there, but keep it quiet as JT hasn't paid for my blues yet lol


Interesting, thanks mate. I take it my car runs 3.8bar?
yes, they changed to 3.8bar when they swopped to ME7

[JT]

boll**ks, shouldn't you be working? lol

[JT]

working on the car,yes

but i'm not! lol

but i'm not! lol
oh what a surprise (yes i'm being sarcastic lol)

[JT]

but i would be interested in getting both sets of my blues in martins fancy bath!!! :)

Send 'em over mate :-)

cool!!!!

I just need to get the 2nd set off some bloke up north!! lol

[M-R-P]

So...
With the aid of a home made injector pulsing/flushing kit...

Whenever you're ready mate. (hope you're not paying too much lol)

I also have a 3.8Bar FPR from an early ME7 fuel rail if anybody wants it?

[JT]

looks like you have turned your kitchen into some sort of science lab!!
all it needs is a bunsen burner from school!! lol

[M-R-P]

Meths and naked flames don't mix dude lol

[M-R-P]

I was scratching my head, wondering how to get the filter out....

Will it fit into my rail mate?That filter removal vid is a treat.

[M-R-P]

Don't know tbh mate.

[V70 Graham]

Mad scientist, Anne kills me everytime I bring a car part indoors, let alone on the kitchen table !

[mitchyboy01]

Why would plod fit smaller injectors and cause it to run lean. Seems strange lol. Get them blues in quick =]

That's the plan dude ;) just waiting for the rebuild kit.

Post #11 ;)

[M-R-P]

Rebuild kit arrived earlier. Took 5 minutes to fit the filters, seals and pintles. 20 minutes later and my newly refurbed blues were fitted (note to self - relieve pressure from fuel rail before pulling the rail off the fuel pipe lol)
What can I say? She starts faster, runs smoother and pulls harder at the top-end :D
Happy M-R-P

I also saw a steady 42 mpg @ 35 mph in 3rd :eek: gonna do a run tomorrow that I know always makes between 32 and 35 mpg to get a better idea of what improvement there is.

[Dangerous Dave]

Nice one matey :D

[M-R-P]

Yep!

I was hoping to get the kind of improvement that I did so happy days.

[stevmo]

what you doing with the old injectors as I'm thinking they may be ideal for my 2.0 :D

[M-R-P]

They will be refurbished but after that, I'm not sure.
One way or the other, I'll have a set of oranges up for grabs at some point.

Did the 26 mile round - trip to my mum's today and even though I had a bit of a "run - in" with a c220, here's my MPG when I got home...

http://i1100.photobucket.com/albums/g413/martinrpeachey/Snapbucket/4E753417-orig_zps0fa21687.jpg

Pretty chuffed. I'll go again on Sunday and try not to race anything lol.

[smithy]

That's nice mate how's the performance of it compared to before

[M-R-P]

Much smoother mate, with notably more torque after 4k rpm.

Not only were the oranges underfueling, but their filters are pretty gunged - up, as were the nozzles. I'll be rebuilding them soon.

[Kingsford G]

32mpg for me driving like a mrss daisy

[M-R-P]

32mpg for me driving like a mrss daisy

I suppose it depends where you're driving I suppose. The drive to my mum's has 30, 40 and some 60 mph speed limits, a few sets of lights, a few 2nd gear corners and some steep hills. I briefly saw 41 mpg but a set of lights ruined that lol.

[stevmo]

Let me know when they are refurbed as if they can help my economy and drivability i'm game

[M-R-P]

These ones are spoken - for as a part - x but the resulting old injectors may be up for grabs, once rebuilt.

Im talking about steady 70mpg run.

[M-R-P]

Im talking about steady 70mpg run.

I'll give that a try and let you know mate. 70mph is about 2-2.5k rpm so should be pretty good.

[M-R-P]

Mum's and back again yesterday and I proper granny-drove it. Saw 40.8MPG!

Cruising at 70mph sees 36MPG.


Sweeeet!

I don't think even Graham sees that kind of economy lol.

I don't think even Graham sees that kind of economy lol.

So Graham is the bench mark in economy motoring? He could spoil it by driving it like a savage for a while!

Tony.

[LiamT4]

I got 34.6mpg driving down from leicester to devon last week, cruising at about 65-70mph. Over the whole week of around 600miles of driving i averaged 28.2mpg, which aint bad for a 4.4 v8 auto. Some fantastic roads around north devon too, so had some enjoyable drives.

[V70 Graham]

I don't think even Graham sees that kind of economy lol.

Over the year so far I'm on about 28mpg not too bad, had her up to 37mpg when we went to Wales :o
