thanks.

lol nahh piss the stockos off get a merc 6cyl ( or 8 cyl depending on how big ya motor is) bet flowage and pump from a merc 99 on wards they fit suprisingly got one on mine

the computer will pump a stoichiometric 14:1 air-fuel ratio. unless you have devised a method of drawing significantly more air into the engine, trying to flow more fuel is a waste of time!

hi, as per my original question, all i wanted to know what the original vn pump flows , so that when i find some used ones i dont get one that flows less than the standard.

[jules]

no idea

why don't you just make sure to buy the right type of pump and stop worrying about flow rates?

[krawczuk]

why buy when i might be able to get ,a used one or dont want to get a new one ?

what about if i had several efi pumps that are suitable? flow more than a vn one ? why then go out an d buy one ?

[jules]

just go off the power then. the VN made about 130 flywheel kW. if the pump you are going to use is off a KE laser making 50 kW then it won't flow enough.

that would work as a rough guide.

whats that got to do with the fuel pump ...???
dont u know that u increse pressure you can get more power ????

[pathfinderus maximus]

ah theres a little thing called a fuel pressure regulator

to an extent, doesnt matter what pump you have, the regulator has the final say

i have a hi pressure pump for vl feeding my series2 vn v6.
just get a pump from a wrecker and bobs your uncle.
actually i have one, which state you in?

[krawczuk]

ah theres a little thing called an adjustable fuel pressure regulator......

[s0sage]

now now kiddies lol
your both right

you CAN fit an adjustable fuel regulator... BUT you still are left with the problem of needing to get more air down the motors throat...

OTHERWISE you should attach a bucket to the end of your exhaust to catch the unburnt fuel pouring out so you can recycle and save some money!! lol

you need wider throttlebody or twin setup OR drill some holes in your manifold or something see how that works

if you check this the actual stoichiometric ratio of any internal combustion 4stroke petrol engine is 14.7:1
