Who runs what ? And what sort of power are you running ?
During mapping my uprated 023 intank pump started to run out of pressure higher up the revs. Unfortunatly unlike saphs and 3 doors with external pumps its harder to find a upgrade, so are use running an external pump inline to boost pressure or running a swirl pot.
Im planning intank to a swirl pot then two 044's from there to the rail, returning to the swirl pot then overflow back to tank.

 

I´m running as you have planned, works as a treat

 

What power are you running.

Mark

 

Not sure Mark its still being mapped but its looking likely for over 400 atw as its showing around 380 at 6000rpm and 1.5 bar but its starting to go lean as the fuel pressure is dropping off. Engine is built for over 2 bar and 8k rpm , running a T4, similar spec to Euans.

 

hmmm nice spec ! are you making the swirl pot yourself or buying one ? kwno a tuner who make a brill one exactly wat u want

 

dunno what exactly mine is but its a harvey one.large swirl pot and pump under the drivers side under rear seat .

 

@bullett: Do you have some pictures of it and maybe a website i can check out? Just what im looking for you see.

 

thats the one m8 they work great they can have single on twin for your feul pumps !
i think a common one for big spec is lift pump from tank to swirl pot feedin 2 044 pumps also the system is pressurised i think

 

ring harvey m8 sure he can help and email you some pics if you want ! also i think there is some pics may be on paul ripleys resto thread

there you go m8 https://passionford.com/forum/showth...=82321&page=45

 

Thanks J1mbo!!

 

The pumps and swirl pot are getting sorted through Mike so it will be one of Harvey's set ups ,just hope there isnt too long a wait for them as realy want the car finnished for next month.

 

Neil, i think 2 x 044 may be a bit over kill mate, and will quickly out pump the intank 023 lift pump.

if i were you id run 2 x standard 2wd fuel pumps from the swirl pot, these will happily cater for 550bhp (ish)

which is probably what Mike will suggest if your getting it thru him.

 

havent got any pics as yet tbh.will see if i get a chance in the next few days.mines only running the sinlge 044 pump i think plus the intank one.not 100 per cent on that.im back at harveys end of june so will know the full in's and outs then

 

Kelv that is what mike advised when i talked to him, but Alan said he prefers the 044's for maintaining pressure , im back at work now so will leave it to him and Mike to sort out this week. 2x 2wd pumps works for me as there cheaper .
Just hope the swirl pot doesnt take long to get as things were going well with the mapping so, hopefully it wont take long to sort this out and get back to it.

 

Ok. Keep us updated....

 

Would you not be better using a proper lift pump like a Holley Red Top to feed the swirl pot from the incar tank - as you want low pressure but high flow to keep the volume in the tank - then have 1 or 2 044s feeding the rail??

 

depends on what setup your run neil??? my braided fuel lines run a internal dia of about 7-8mm i will be running a cossie lift pump feeding my swirl pot and run 1, 044 pump feeding the rail.... but i am going to have the cradle made to house 2 044's so all i have to do is add a T piece to run 2 044's if needs must later ....

 

Heres mine M8 from Harvey

 

Thanks guys
Jon that is the same swirlpot and pump set up im trying to sort justnow, as i want it all under the car and out the way.

 

My friends one. Not quite finished in this picture, but you get the idea...

 

Two 044 pumps seems massively overkill to me for a T4 .

I have the same turbo as you and run just two 941 (2wd) pumps, but if that is what is recommended by Alan, then he obviously has his reasons. A single 941 is good for 400bhp and a single 044 just about 500bhp, so two of these seems completely unwarranted at your power level. I'll have to have a chat with Alan and find out his reasoning next time we speak .

 

Mike i think it was todo with testing done on Euans car they ran one 044 with good results but have now added a second one to keep the pressure up.
As you know its now in hand and i will be running the same set up as you, i wont be getting near the power where they had to add an extra pump to Euans anyway.

 

mine single 044 was just starting to struggle at over 490 ATW so woyuld imagine anything approching 450 ATW on a 4x4 would be the same.

A swirl pot is defo my next mod as with anything under half a tank it effects fuel supply even in a straight line due to the linear accel on my car.

 

i suspect alan wants two 44's as when neils goes for the big exhaust and 500 ATW he wont have to swap again!

 

Not going to happen I think 400 will do me

 

Neil, not that you really need to know but mine is consisting of...

Pro Alloy fuel cell, then Holley pump to feed the swirl pot, then the fuel rail is fed from the swirl pot by an aeromotive fuel pump.

 

if yours is 490 at the wheels what is it at the flywheel? isnt it on a t4?

 

Most my car has made is 505 ATW but usually makes between 490 and 505 depending on air temsp as we dont use and fudge(correction) factor.

I know if my air temps are below 40 deg on the road I have 500 ATW.

Fly wheel I add 50 bhp as my car is ran in 4th gear and at high roller speeds due to wheel spin in any other gear.

Yeah its on a T4 specially developed for my car and now sold thru CR turbos.

 

my pump should be ok euan? single 044

what do you think im looking at once mapped?

sorry for hijack neil

 

Hey col...

no reason you shouldnt be on 400 ATW once mapped if you compare like for like with my old spec you are very similar.
One 044 pmp should be cool as that was the only mod to my fuel system at the time.

When you getting it in for mapping?

 

shouldnt be long now mate,i know i keep saying that,but ive had a few issues,everything is well now though

only thing im needing is the -12 ggr breather hose and unions,and i really grudge the price of these bits,but need it done

hopefully now the rr day etc is out the road alan can get it in at a weeks notice

has he got a feel for the collins ecu now neil is on the go?

 

Its very expensive for the aero fittings in that size, are there no places you can get something similar in rubber as a stop gap?

The collins ECU "should" control the normal running of the car with no problems(Alan hasnt commented on it saying otherwise so it must be ok) but he does say its missing some of the features of my ECu that allows him to smooth the map espeically at idle with cams timed up.

Neils car, from what I have seen doesnt seem as easy to start as my car and does sit on 3 for a good few seconds when stone cold where as my car almost starts as a normal cossie.

 

il be retaining the standard icv for just now until i get the larger throttle fitted

i could get a rubber hose but,i still need the unions so i might aswell just get all at same time

 

Col from what Alan has said he is starting to get useto the Collins ecu and was making good progress on mine, as you say if your keeping the iscv it will make ours easyer. Alan has found a fault with the wiring for my coolant sensor which partly explains the starting problems from cold, once my car is warm it starts and idles fine. Think the plan is dial in the cams then if it still doesnt idle well from cold, i have my iscv mounted up ready in a remote housing.
Any idea when yours will be in at ava will be good to see your bay with all the new mods

 

has anyone kept the original fuel tank.. and mounted a bosch 044 pump in the boot with a swirl pot and then ran the pipes under the ar to the engine?

 

Why would you put it inside the car and take room away from inside the boot, when it all fits underneath the car?

 

ideal

not sure when yet hopefully be next week or the following

 

cus i already have a swirl pot so do i realy want to give you anymore money

il give you a call regardign that pump up swirl pot mate.

 

It would cost you more in fuel lines to do it this way and would mean a buzzing smelly pump inside the car. You will need ear plugs as well .

 

iv got the lines aswell

o well iv got the straight cut box comming so why not add more noise
