a crazzy dual fuel system

[cummins king]

okay guys i will have all the numbers in a few hours, on how much case pressure there is, at idle and when driving, and with the ksb and with out, with stock injectors

pimp shizzle i have a gauge on my new pump but dont wanna waste the time to put one on my current pump so gimme the info

[cummins king]

well would you like the good news or the bad news first,
well the good news is theres no good news
theres lots of bad though
1. industrial pump tops dont work with turbo ve,s because bosh desided not to put a machanical shot off, if anybody can explain to me why feel free to.., so i machined it out and put the shot off in, weither it works or not or i it leaks is not confermed, because i cant get the truck to run witch leads me to point 2. how would you turn a truck off with out an electric silioyed or with out machanical way, does the board infront of the turbo really work or did i just risk my truck running away and blowwing up, the reason i dont know if the machanical shot off will work is because i didnt see the posision that it can off in, and im afraid that it will run away because the 3200 spring might not be in the right place.
3. i put the gauge in the return temporalerly just to see the presure, but the hydrolic fitting that seem to be a good fit leaked like a #$%&*@. JB welding is next setp, so in the end no readings, but tomorrows another day.
just one question for who evers reading this long post, if the ve pump has air in the top because theres no return the truck shouldnt start, right
and if you dont have the return line pluged what will happen, does it matter exept fuel may come out of it, will it affect starting,
thanks

Now to get it under load and see the results.

At cruise, approximately 1800 rpms 70mph.
KSB off:
120psi
KSB on:
165psi

Light acceration off from 1800 rpms.
KSB off:
100psi
KSB on:
Don't remember, I am trying to drive.

I don't have any numbers for WOT, road conditions haven't been the best for that sort of fooling around lately.

[CumminsPride]

Thank you JD!

with the new engine in the s 10 i backed outa the shop got out on the highway that was about 3 min woth of running then i did i burnout to around 150 mph i think i did that about 5 times till the sherrif showed up and thats my break in proceedure lol

LMFAO!

[DTanklage]

thanks mike

what did yours make at idle?

i think anyone that is gonna post cases pressures oughta also post the specs for their supply (everything) (lines, what lift pump, what filter, what pressure, etc)

the numbers that i am curious about are at wot under load as the r's increase

probably a 2 person job

[JD730]

what did yours make at idle?

800rpm
KSB off:
80psi
KSB on:
150psi

i think anyone that is gonna post cases pressures oughta also post the specs for their supply (everything) (lines, what lift pump, what filter, what pressure, etc)

low pressure piston lift pump, stock lines, stock filter, pretty much stock except for the pump. Was making 15psi, but I need to redo the gauge so it works right.

probably a 2 person job

Yeah, it would make things easier.

[DTanklage]

800rpm
KSB off:
80psi
KSB on:
150psi

i wonder if that means its hard on the pump to be driving around all the time with it activated?

when are you gonna rap that thing out and get some numbers???

real curious what it does

[JD730]

when are you gonna rap that thing out and get some numbers???

real curious what it does

When the roads are dry and its not raining.

[bgilbert]

Don, yeah its hard on the pump to run around all the time with the KSB activated.

Cummins King, yes the board in front of the turbo works to shut off the engine. Just watch your fingers . Air in the pump top would allow air to enter the injection lines and cause hard starting, until all air to routed to fuel return manifold (injectors) and back to tank. I would guess with the pump fuel return unplugged, the pump would have a hard time building pressure and not allow starting. It might bleed out the air though.

[DTanklage]

shoot, that thing is making 150 psi at idle

i would say the air is already gone

compressed to nowheresville maybe?

dunno

but since i know kta's system works i know you dont need a bleed at the top of the case

hey, there is an idea - if you are worried about it install a bleeder!

[cummins king]

okay guys got my truck going, but please read the hole post lots of cazzy info, kta you to,

okay
ksb off
idle - 74psi
idle in drive - 70psi
at 80kms (50miles aprox.) - 110 psi
100kms (60miles) - 120psi
romping- 150 psi

ksb on
idle - 150 psi
idle in drive - 143psi
at 80kms (50 miles aprox.) - 165 psi
at 100kms (60 miles) - 175psi
romping 185 psi

okay joels special

ksb off
idle 150psi
soon as i touch the peddle (in drive) 225psi

ksb on
idle - 200psi
touch the peddle(1500rpm( in park) - 250psi got scared and let go of peddle

okay heres what my dual feed set up looks like

http://i274.photobucket.com/albums/jj25 ... G_1112.jpg

this is what i did to get those high numbers, i dont know if i should of done that or not i was told buy a expert that it would give me a nother 20psi in the pump not 100psi or more, in this picture there is a little nut, beside the line and between that nut i took a punch and i punch it down 1/8 of an inch

http://i274.photobucket.com/albums/jj25 ... G_1113.jpg


heres the proof of the psi this a 300psi gauge, and its with the ksb off first pic is idle and second pic is 2000rpm

http://i274.photobucket.com/albums/jj25 ... G_1116.jpg
http://i274.photobucket.com/albums/jj25 ... G_1117.jpg

any info would be great

[cummins king]

sorry the dual feed isnt hooked up yet the one line is for the gauge, and the plug on top is were the second line is going, i put the ball valve in so i could blead off the air, its 1/2 inch all the way into the pump

oh i almost for got, this is the most puzzling part, i lost 10pounds off boost, before i punch that thing down, and it made no difrence after i pumched it down, need help there
