flowin fuel to keep the ve cool

[cummins king]

has anybody drilled the banjo bolts on the return line to get more fuel flowing, i would think that thats abetter way to flow fuel istead of massive injectors,

or has anybody dilled the banjo bolt on the ve pumps return

or put new and bigger return lines

Why would you want to drill the return banjo bolts at the injectors? They are only there to return whatever fuel bypasses the injector's nozzle for lube. If you have too much fuel flowing at the injector's return you have a bad nozzle.

Have you even looked at the return banjo bolt on the VE???? It has a small hole in it and a screen filter. If you enlarge it you'll have more fuel heading to the return and the stock vane pump will have even more trouble maintain case pressure with large sticks and WOT. Then you'd have to rely even more on a secondary inlet to keep case pressure up.

im not worryed about pressure the idea it to flow the fuel so the ve keeps cool,
FORD is running huge injectors to move the fuel, so instead of filling your tank every pass, because you cant burn all the fuel and its all going out the tail pipe
make the returns bigger so it will still move the fuel and not lose eficcienty and it wont blow so much black smoke

Not worried about pressure? Then how do you expect the rotor to get filled with fuel? Your analogy reminds me an engine I took apart one time, it had the pressure regulator stuck open. It had plenty of oil flow to the pump and right back to the sump, but non of the parts that needed it got enough oil, wiped the bearings out.

Ok, what does that have to do with return lines?????

because you cant burn all the fuel and its all going out the tail pipe

Huh?? He can't burn all his fuel because he doesn't have enough air to do so.

make the returns bigger so it will still move the fuel and not lose eficcienty and it wont blow so much black smoke

There was a time when some injectors didn't have a return, just a high pressure line. Black smoke is from not enough air and big injectors. Honestly there shouldn't be anymore fuel bypassing the nozzle than there is on a stock fuel system.

i dont mean no pressure but when your runing a big aeromotive, your not going to have this problem

Ok, what does that have to do with return lines?????

he said he wanted to have big injectors to make power but also to move the fuel to keep the pump cool

Huh?? He can't burn all his fuel because he doesn't have enough air to do so

you need 18 times more air then fuel to make no black smoke, im just saying the more the black smoke the more unburnt fuel (inificient)

did i clear up what i was trying to say Grrrr....

black smoke is unbernt fuel because you dont have enoughair coming to complete the combustion and a few other small veriables, but what im saying is i wrather move fuel through the ve and back into the return lines then wasting it by through the injectors, i cant push enough air
to burn it

and by opening the return lines up a bit (not talking 1/2 inch NPT hear ) a bit! then you will move fuel through the IP.

am i right or am i missing somthing

If I understand the VE pump correctly, that sized orrifice in the return line is so that with a stock lift pump you have a certain internal pressure to keep the pump primed and not cavitating.

By the same token should one increase supply pressure to the 70+ psi some are talkin here and the increase in injector sizes, one may not need to increase that orifice to increase flow as it is already happening past the injectors and thier return line

As a matter of fact I suspect if you did increase the orifice size, even with the increased pressure you would cause cavitation in the pump cuz the bigger injectors would be usin a lot more fuel, ergo more flow and the pump might not keep up with the demand if the bypass/return was passin too much fuel.

just my .03

the 6x20's are the max the 12mm v will take atleast mine anyway. with these sticks i still average 20-22mpg on the highway like i always have but go beatin on the throttle and it goes down to 12-15. i dont have enough air from the turbo to clear the smoke but i can hit the magic button and turn it into a gray haze. the return system is there to remove excess fuel if you sticks are in good shape and are large enough for the amount of fuel you tryin to push out of the pump then there is no reason for any larger lines.

[Underpsi]

Bigger injectors take the strain off the VE because its less restiction. Example if you were blowing through a small straw it would be much easier to blow the same amount of air through a bigger straw and you could actually blow even more air through it depending on the size and amount of restiction you could take

[cummins king]

i wasnt really thinking bigger line i was thinking bigger bango bolt holes, only trying to move asmuch fuel to make the most power with the least adnount of waste resulting in less smoke, if it were a perfect world

[ford69557ci]

lol better buy a common rail or really research your turbos and get the perfect match

[cummins king]

lol perfict world, i wonder how banks does it you never see any smoke any more from them not in there sidewinder or the drag truck, i know they use nitous but they also must have some other stuff we havent heard about

[seeker1056]

its called a computor and a variable venturi turbo with sensors in each exhaust port

Fuel is metered exactly per need and the trubo is regulated by computor as well, thereby not wastin fuel, ergo no black smoke

people have questioned why he makes so much power on so little fuel - its becuase the extra fuel aint contaminatin the burn and slowin it down

black smoke may make the ego happy but it aint doin nuthin for performance

[cummins king]

cool

[ford69557ci]

yes banks has the tech and money to do it but still without nitrous on the spool up he would still have some black smoke. if a pull truck can belt out black smoke and make 800+hp then i dont think it hurts the power that greatly or else the big dogs would be figurin out how to make theirs burn completely clean

[cummins king]

yes, if you could use all the fuel in a complete burn then then you would make more power, i have nothing against black smoke it more cool then anything, its just the pos sitting around a corner
lol
