anyone know how much these are new.
are they worth getting
cheers

Stoo

Think they cost about £300 fitted,not sure though.

Worthwhile if your running alot of boost

Anonymous

Think ive seen them for about £120 right up to £350!!!!

Depends on the fuel injection system you are using and how much power you are running.

WutangRS

it was the erl MF2 one that i was looking at (think thats the one)
dont want to run silly boost on a 1600cvh just want over 200bhp but with abit more reliabilty currently running 18psi.

it did have head and cam but a belt jumping a tooth saw to that. have a new P-engineering stage 3 head and kent 35 on the way so hopefully i can get some more out of it for the summer

lamar69er

I highly recommend a 5th injector, ive got a ERL MF2 driver on my Power engineering 1600cc 200bhp, deffinelty needs it, im running 18psi at the minute, im hoping to get 25psi out of it soon so might even consider a 6th injector, or possibly water injection! There a peice of piss to wire up, just get an expert to set it up properly on the rolling road!

WutangRS

where did u get it from and how much was it can i ask.
what do u reckon the second hand going rate should be

cheers dog

lamar69er

mine was on the car when i bought it, i think there around £150 new, so id say £80 second hand, i think stu does his own 5th injector driver kit, pm him for more info!

nigel b

if you get a 5th injector get a mappable one
have you got a hybrid turbo etc..?

Anonymous

Theres one on E bay at the moment for £140!!!!!! WTF????

Thats more than they are new!!!

WutangRS

lol yer i know its up to £200 it was that that made me ask the question. though that was alot.

no its not a hybrid yet. probably going to do a zetec conversion as ive been given a 2.0 black and all the escort bits needed for free so would seem abit rude not to

BODGE

the ERL kit is about 300 notes new, the driver on its own is 200

I paid 375 for the entire "kit" which was the mf2, 3bar, 803 and the fitting bits. That was a good price, farely sure it don't come cheeper new

slimwynn

can u fit these your self?

Rick

ERL MF2's are fantastic bits of kit - i higly recomend them. Better fuel economy, better driveability, and big power potential.

reality

Bit of a waste of time really.. most KE units can fuel up to about 210bhp if they're in good condition. but the metering unit chokes at about 230bhp.. so I guess it's useful if you want to force that extra 20bhp out of the compromised system! Going to efi is a considerably better route..

Rick

metering head does not choke at 210hp, ive seen well over 280... And running a 5th means u can have off boost fuelling at lambda 1, and significantly better economy.

gee1599

the metering unit chokes the fuel at about the 200bhp mark you can get more BUT thats when you start melting something

Rick

If you haven't got a clue what you're doing, maybe thats the case...

Well, I ran 250bhp on a 4-injector K-Jet set-up. NO fifth injector.

I also did 155mph on this set-up.

As Rick says, it's all fair and well to say that it WILL do bigger power, but at the expense of off-boost fuelling. Thats a fact. A car that is set to fuel big boost on K-Jet will have an AFR off-boost that is as rich as when it is on boost!

Welcome to sub 200 miles to a tank-full!!

Nice old thread, by the way!!

JamboRS

im running 214@wheels with no fifth injector and still on mfi,but i may add that im running 2 std rst fuel pumps,one feeding the other and theres still fuel there for more,if you know what your doing with the mfi you can get good power from it,take the green shed from ava,made 275@wheels still on mfi,as christian says but fuel economy is greatly reduced,well mine is anyway

Rick

where as i get 36mpg..... hmm which to choose - i wonder....

C14KEE

Hows this for a question then?

Im on MFI and im going to switch, money isnt an object and i want antilag, and 35mpg is sounding very good.

what do i choose...because from what i can see theres a few choices out there.....

Rick

You go for something like P8 or Omex

JamboRS

stay away from 5th injectors,most are botch jobs anyway,look at lucids s1,lucky he took it to get checked out by a pro

go with different management like rick says,not many people can get reliable bhp from the mfi

Rick

Jambo, the MF2 isn't a botch. just becasue people are unskilled, and don't know how to fit and map them, doesn't make them bad - it makes them crap tuners.

JamboRS

so the tuner that fitted lucids 5th injector is a crap tuner,iirc it was stu at msd that set up this car,didnt quote you so you can take that comment back and ill edit mine when you do

as i said theres more reliable ways of gettin power from mfi and 5th isnt one of them,but my tuners knows a thing or 2 about mfi so im lucky i suppose

Rick

JamboRST

I said that the MF2 was a botch, and that if a tuner could not fit or map it that they were crap - and i stand by that. What are u saying? That MSD fitted an MF2 and the engine then melted?

JamboRS

no im sayin that when lucid took his car to get checked out the fuellin was all over the place,u said and i said that it was stu at msd that set up this car

so your sayin that stu is unskilled,doesnt know how to fit and map them and that he's crap,not me,im just sayoin how the car was when it was checked out,still stand by that comment?

also you say in one post mf2 isnt a botch then another post says it is a botch,which one is it

Rick

No, i'm not saying that at all - your putting words into my mouth. If the fuel was all over the place, and it wasn;t sorted - then there is obviouslt a fault with that car. That does not make 5injectors unreliable - it means that car is...

JamboRS

how can i be puttin words into your mouth,you typed them first not me,seems your back tracking now
anyway the 5th injector is now disconnected and car is runnin sweet at this monent in time,it will be goin back into get fuellin modded proper and will be set up without 5th injector,run less boost and make more power,cant argue with that,as I said my tuner knows the mfi system inside out,knows what works and what doesnt and dont think theyve ever fitted a 5th injector to any of there cars and they make more reliable power than similar cars that have got them fitted,anyway convo over,im not arguing over this mate,we'll agree to disagree and leave it at that

Rick

AVA fitted a 5th inj to the green shed a loong way back

JamboRS

correct ava did fit a 5th inj to the green shed and then whipped it back out as it caused more trouble than it was worth,it now has the same set up as my car,2 fuel pumps,phone them up ask them to fit a 5th inj to your car or any car and theyll tell you to run and jump,not worth the hassle as they are the mfi guru's and know better ways off gettin power from it,thye dont just go what it says in the manual,all there knowledge is thru experience and tried and tested,what did the green shed make on mfi?275@wheels without 5th inj,anyone got that much power from the mfi yet?

Rick

yes, a few - don't forget that ava's wheel readings are much higher than other rr's. AVA defo know their stuff, esp mfi. But a 5th inj prop mapped will beat the shit out of any mfi only system if only for the sensible economy. Mine has never once give me any trouble.

JamboRS

ok then
1 bi9trb 290bhp@fly 195@wheels at ava
2 lucids s1 230bhp@fly 155@wheels at ava
3 mike r saff 500bhp@fly 395@wheels at ava
4 my mates rst 225bhp(lee reynolds old one) 167@wheels at ava

see the pattern here

so what car has made 275@wheels on mfi with a 5th inj then

Rick

JamboRST

I think you are confused...

AVA's rollers are of a larger diamater and will give a higher ATW reading than virtually all RR's. This is not to say they are inaccurate, it means that if u run 195 wheels at AVA, u get about 170 odd on other RR's. I've seen this many times. Tim Butchers car did 240 odd at wheels at nobles with 5th inj.

JamboRS

you say youve seen it many times,on which cars
also i may state that it may give a lower wheel power as 195@wheels would roughly be 220flywheel where as in england it would be 250bhp@fly,so a bit over exagerated and not really accurate is it,wheel power is true power not fly power unless dyno'd
so your sayin most of the 200bhp cars down your way would come up and make more bhp than it would down there,ive yet to see a car thats came to scotland and made what its claimed,also i may add i have had my car rollin roaded a 2 places up here,both similar figures and davie k has had rr at 2 different places up here and again very acurate to with 5bhp,so tbh mate your dribbling pish about ava reading more than other rr
also did 2 of ava's cars not compete in a rst thrash years ago down in england and really show up some of your claimed 250+bhp cars with 70bhp less

Rick

This is going v off topic but...

AVA only work with wheel figures. There wheel figures are always higher than any other RR. So yes, if a car does 200 at the wheels here, it will defo make more at the wheels at at AVA.

C14KEE

nice thread

JamboRS

as i said i have had my car rolling roaded at robinson tuning and it made 150@wheels and made 149@wheels at ava so it must a scottish thing then to over read
tbh mate ava are known to be very conservative with power readings and are no way known for overreading,any english car thats came up here has never made even close to what it made down your way thats even takin into account from fly to wheels
still would be good to see some of these supposedly 200@wheels cars comin to ava and actually recording 200@wheels
my example of the rst thrash proved that these ava cars that competed were makin similar if not better times than of the claimed 250+bhp cars that were there,that for me shows that these ava cars were running more bhp than what the english cars had,and they were meant to be 250+
forgot rollin road,times and top speed are a better guess at cars power than figures
so either these cars were makin more or the english cars were makin less,therefore blowin your stupid claim out the water
