Im in debate with one of my mates who reckons he can run 400 bhp on a standard fuel pump i said no way but before i start disputing it id just though i would ask for peoples views on it........

So what your views on it, whats the most you can run on a standard fuel pump???

As far as I am aware 4000bhp is fine on a std 2wd cossie pump if the pump and wiring is in good order. I certainly ran close on my old Saph! Whether or not it is adviseable is a different matter though!

...hello i found that 380bhp is the limit to a std pump before starting to lean out...so fine for stage 3...after that its 044 time..

BigErn

A lad I know went to get his set up running stage3 and they wouldnt touch it till he put a 044 on cos they said it wouldnt be fuelling enough

i'm using one on mine 420bhp............its air i can't get enough of......not fuel.........

...pete along with your second hand head bolts your car is sounding more and more like a disaster!...I know your say you drive it flat out in top gear...but i wouldnt.

Was that rewired with a good relayed supply though?

the cars mapped into the red in every gear Phil............phone Ahmed if it worrys u.............the fuel pressure and rate was tested before mapping.....its fine

phil how did you work that out? you never had the car rolling roaded so how did you know the bhp figure?

...some of the people who i supply have rolling roads so i find out exactly how my products perform

I think for safety then a 044 is ideal for anything above 400 but I know of plenty of people that do not use them with over 400hp

None of the engines I know of using original pumps have failed in any way but I would run a 044 for peace of mind.

Wiring like anything on a car is crucial though

Lloyd

i run twin standard pumps,twin fuel lines,one to each end of the fuel rail,and a fuel return from the center of the fuel rail to the regulator.i would only use a single pump up to 360 bhp,after that use a 044

rabmc

I put a 044 pump onmine as i was going stage 3 , i just had to look at my pump to know it was no good

bud-weis

from memory when i switched to greys and 2 bar on a T34.63 Karl advised me to go for an 044 (on my old car)

doesn't seem worth the risk to me, running a 20 yr old pump at double it's intended use

it's not as if 044's are dear!

did have 2 take offs on the fuel tank to lloyd?

yes jay 2 15mm fuel pipes from the tank,had it made by pro alloy.

but if u buy a new one and re-do the wirering.......anyway like everything i say on here........just going from experence or what i get advised......

bud-weis

very true!

although i'd defo say that in this case what may work for one, may not work for another..which is why i think it's a little risky IMO.

if it works fine for you and you have plenty of fuel at the top of fifth then that's spot on

Well they aint cheap to some of us, old Martin moneybags there!

..everyone else knows best..its your engine..i wish i had money to burn

rapidcossie

044 should be first mod for any cossie over stage 1

Fudgey

if the wiring has been replaced with new and done properly, and the pump is in as new condition then there is no reason why it will not be safe upto 400bhp

anything over and it would be advisble to get an 044

What do you mean by this...any drawings or ??

thanks for the replys people

Deleted by Request

..there is no reason why it is safe upto 400bhp too..even though i say they lean out at 380bhp by tuners you still say bollocks ...a std pump has a rating which is all different pump to pump..it ha a min and max flow rate..so if you aint lucky you blow ....they chose the pump for 204bhp..not for 400bhp...just so happens that some may just reach it...but others fall to stage 3 maxxing out...the only way to be SAFE is use the mighty 044 on tuned YB's..not from me though as i hear you can buy cheap used no warrantied shite off ebay..thats whats suits the ford crew ..then you all whinge when you blow up

Fudgey

iTrader: (4)

you sure them ebay adds arnt just more of your alias's and thats how you make your money?

bud-weis

i wish mate!!! trust me i do!!

but if you can afford a 400bhp cossie, £120 shouldn't be too much of a problem

Cowboi

just what i was thinking.

sounds like many std pumps are doing the job.
but i know if i was running a decent powered cossie i would want to eliminate as many risks as possible.

cant stand driving along wondering if something is going to break.

Ginge !

its one of these things though aint it

alot of cossie boys wont get to 5500kprm in 5th gear but when they DO go high revs up hill in 4th gear then the car will feel more powerfull and either melt or they get to the top

a BRAND NEW standard pump will do 400 bhp if set up,,,, for how long dont think anyone knows for sure as its like saying " i dont have to lock my door when i go on holiday as nobody breaks in"

just takes that ONE time for you to be proven wrong,,,, and considering a 044 is 50 quid more than a BRAND NEW standard pump,,,, would you not pay the extra to save 2 to 4k on a rebuild

im sure a vauxhall nova pump would be fine for some cossie owners on greys who never drive there car hard due to them nor wanting to "abuse" there car

loan it to someone like RSGus/jb fletch/benn/popeye and then see what happens to the 20 year old rusted in the cradle pump,,, prob never had a new fuel filter fitted either car

the worst thing ive learned about cars is the BEST cars are the ones you spend money on and you dont feel any difference from before,,,, thats why its called preventative maintanace i guess

Run a bit of 30map cable (with fuse at battery end) to the back of the car and install a relay so the old fuel pump wire switched it on and off and use that to the pump so it sees a better voltage than through the old wiring.

Cowboi

at a guess i'd say chip means do this.
top pic is old setup.

bottom pic, you use the old wiring to the pump to switch a new relay.
and run a fresh supply fused from the battery via the relay to the pump.

as long as the old wiring manages to get 12v to the relay u will have a good supply to the pump.

worth making sure ur earth is good while you at it too


escuse the drawing. just made it quick to help explain.

Chip, let me know if this aint what u mean and i'll take it off so it dont confuse people

..thanks

Dingy

I ran a standard pump at 400bhp with no issues....fueling wise...

My engine melted due to the map tailing off the fuel at the top end though..nothing to do with the fuel pump

Stu.H

Bud-Weis,

Do you remember what pump Karl fitted to mine in the end?

I'm guessing the proper 044 as he said fuelling for 500bhp would be possible now

it is an age related thing not a fuel flow related problem with the standard cossie pump

Porkie

iTrader: (1)

This post shows EXACTLY where cossies get a record for bad reliability from!

gingeRS

does the 044 pump have the same fittings as the standard pump then?

so its a straight swap?

it does amuse me when people will spend hundreds of £££ on shiny bits like cambelt covers and slam panel blanking plugs but when their fuel pump gets a bit noisy, they hop on ebay and pick up a second hand standard one

...........aint that the truth.........at grove mark has done flow tests on 044's..........and standard pumps have been better..........like said ^^^^^^my car has been flow tested and mapped into the red.............its fine........... edited to say" no Mark hasn't told me this.... it must have been someone else ........this is why i'm now buying a new fuel pump................
