Ally Tank Part Deux

Well for those intrested, got a sytec injection pump yesterday, tis a monster capable of shifting 280l/hr @9bar:eek:

its only being used at 180l/hr @3 bar, so it is probably a little overkill! hehe couldnt resist thou.

REMOVED TANKS

NEW PUMP AND HIGH FLOW FILTER

AFTERMATH...................LOL

Still got a couple of jobs still to do, getting hold of some braided hose, and running the lines in the car.

started it up this morning, and it seems cool

MatB - My dogs dont swear!

BenR - Thanks for your help over the last couple of days!

Derv - Thanks again dude.

hahahahahahahahhahahaha!

very good!

Ben - say 150, ish! dependant on how its driven

Its not my every day car you see, so practicality isnt a major concern, speed is! LOL

Actually just come back from the petrol station!

Twas a strange feeling lifting the boot LOL

Pulled that stupid charcoal filter out today, under the front arch, then blanked the inlet manifold pipe off.

Been itching to get rid of that for ages.

Not now i aint got a petrol tank!

It controls fuel vapour emissions blah blah blah!

The things they do to stop you smelling petrol when you open the filler cap! LOL

er are you going to get proper clips instead of those daft P clips on the fuel lines?

I cant imagine them holding up for long with anything like 9 BAR of pressure.
 
BenR

BenR



its only running 3 bar........so weight says. Or are we still talking rail pressure?

what did u use to regulate the pump output.
 
C

Chris_H



from what I can see the pumps running un-regulated as normal from the pics. That means if its delivering 9 BAr @ 14 volts or whatever it is then theres 9 BAR of pressure in those lines.

Unless of course hes using a ballast resistor.

Also I may be goign blind but is the fuel filter before the pump? if so thats not very clever.
 
BenR

BenR



agreed..........i cant see any method of regulation.........for pump output that is.

9 bar.............lol...thats a fair amount, it didnt coencidentally happen to be their most expensive pump too did it! lol

in what NA engine would you want to run 9bar!???

The fuel pump is running unregulated, but the pressure in those pipes is still only going to be allowed to reach 45psi due to the regulator on the fuel rail! as i understand.

but, that said i will be checking the fuel rail pressure soon.

And because of your comments, i will check that line pressure from the pump.

Unless of course hes using a ballast resistor.

nope

The fuel filter is between the fuel tank and pump! why is this not very clever?

quote............

" A fuel filter is required between the fuel tank and the pump. For best results, pump and filter should be mounted low and near the tank."
Also the hoses are soon to be upgraded

Anything upto 1200 BHP i believe LOL

Well firstly I do not know whom told you to put a filter between the tank and pump even if it was Maclaren F1 they are very wrong. The filter is always after the pump. I can give reasons but cant be arsed.

Thats 45PSI in the rail at the actual injectors, the rest is circling about in the fuel lines matey. Lets say you have a hose, you squeeze the end the pressure builds up in the pipe although you are only letting a wee bit through. Your fingers are the regulator the tap is the pump, get the picture? Hose pops off interior of car soaked in petrol and bang.

Are you going to fit a swirl pot? Might cool some of that cycling fuel down.

If you cant be arsed to give reasons why comment?

well as i said, i will take a pressure reading at the pump. Thanks for that! and the pipes and fittings are gonna be changed for braided items!

nope, only if surge is a problem!

I cant be arsed to give a catalogue of answers but with a filter before a pump its more likely to run dry and we all know what happens when a pump runs dry.

I seriously recommend you take note of the fuel temperature my man before the engine melts.

fair enough, but its a high flow filter with next to no resistance

a little extreme me thinks, but noted i will keep a eye on it!

thanks doooooood!

well if its that high flow why bother with it?

But theres no point in me saying anything more, if it dies, well you will know next time.

Cant be that difficult to understand why i use a fuel filter surely????

But theres no point in me saying anything more, if it dies, well you will know next time.

Fair enough doooooood!:)

just put it after the pump........as per what the car originally ran...........

cool fuel..........youll be stuck in a vicious cycle of heating it through the pump/lines, rail, regulator, then the injectors add more heat.......fuel cools the charge. It is important and quite a part of getting an engine to run at its peak efficiency.

Thanks Ben

cant get hotter than it was as standard, exhaust cooking my tank and the fuel lines bloody hot to the touch in the engine bay!
