STOMP....Jeremy I apologize for not calling back during the day today...I was literally backed up bud....I also left the number you gave me on a sticky post on my desk.
I will have a chat with Piers as soon as I can about the head scratcher you and I chatted about too....

I also dug up one of my old pump test sheets when I got home and I'll post some early/basic info here for reference sake...Keep in mind that I am using some very preliminary numbers and not the latest results or methods.....at least for now...

The early VE had a "starting fuel delivery" value of roughly 160.9cc ...
The "full load delivery" came in at roughly 150cc (w/charge pressure) with some work I got that up to 214cc.
You can see that the first two values indicate a reduction in output, as you'd expect when going from the max fueling value used at the start cycle.

With some work and tuning the max supply went up a fair bit but as the pump heated up that flow rate dropped by roughly 20-25%.
We also vaired the supply pressure between 6psi and 18psi and saw no appreciable improvement in the output either....
One of the factors, I believe, is the heated fuel effect. Since some is recirulated back to the supply side that fuel is being heated up in advance of the pressurizing cycle in the pump "head".

I have a couple other ideas if you'll give me a chance to run them by a couple guys and then you and I can chat....sound good bud...???

best regards, bob.....

 

Well Stomp, how did the new pump turn out? Did it flow into the 3's?? When are you gooing to get it on the truck and on the dyno?
Cody

 

244cc's@500rpm's no air
360cc's@500rpm's with air
290cc's@850rpm's with air
266cc's@1000rpm's with air
All of these were done on a Bacharach model 10 test stand. Rpm's=x2 on the pickup. The cc's have already been changed.

This is the dilemma why did it drop so drastically? The only thing that we came up with after talking with a few people is we did not change the test injectors out. We used the Spec injectors for the VE pump. Everyone said that they probably couldn’t handle the fuel that was going to them at the upper rpm levels. The injectors that I run on the pickup should have no problem flowing the extra fuel. Does anyone have any different ideas?

It runs awesome. On diesel only it runs at least as good as when I had my old pump with the water/meth on. When you add the water/meth it really gets fun. It does try to get squirrelly even in 4th and 5th gear. The smoke pours until the turbo’s light and tt will turn daylight into darkness. Even at full boost it will still leave a haze of unburnt fuel. I love it. I still need to do some tuning, but I am going to leave everything the way it is until I dyno next week. I already have a pre dyno with the old pump on the same dyno.

I want to thank KTA for getting the parts made and Carl@ Bradley’s Diesel Injection Service for putting it all together for me.

so you are coming down on saturday?

 

Oh yeah I also had it run away on me 3 times. The fuel screw was in too far. It was kind of scary though.

Yeah Jimmy I will be down on Friday and dyno on Saturday.

Stomp

 

Jeremy, if you go up one size in test nozzle on the stand you'll find it will help the flow a fair bit.
On one run we had a pump go from roughly 150cc of per... to over 200cc per with just one size up in test nozzle or, more correctly test orifice..

Also, are the cam plate and roller ring assembly the stock units??
Perhaps you've got a lift/duration issue or wear issue...
Last thought (it's late..) are you still using the original plunger return springs?? Are they new or used (perhaps weakened)??

 

I have had this pump on for about 4 years. All we did was change out the head/rotor. So I guess there could be some wear issues. After the dyno day I will have some time to take everything back apart and look. I guess I should have done a complete rebuild.

Would you want more lift/duration with the new head and rotor? I know a nice machinest that might be able to come up with something.

Stomp

 

Stomp,

What governor lever are you running? Did you modify the stock one, or use a set up from another application without torque control? Maybe I should ask "start with"

I would guess form my arm-chair engineer's perspective that your flow will be a lot better at higher rpms through your honed injectors than it was through the test orifice -- I think that your mods will give more volume, but without a significant increase in pressure. A bigger orifice will let you flow more fuel at a lower pressure, and now you have the volume to flow . . .

I am curious about the governor lever, because I want to get rid of the negative torque control, even though I do not want to build a high (well, not super high) HP engine.

Thanks,

Alec

 

Just curious if you ever tried the non intercooled lines?? My parts should be here sometime this week. I put my 192hp ve back together last night and i'm going to see what kind of numbers i can flow on a test stand. Keep up the good work!

 

Are the non i/c lines bigger?
-Jim-
and Stomp if yer listening, i want a 4 gauge pod, but no one has them. Where would you suggest? Thanks

 

Hey Jim,

I just ordered a 4 gauge dash pod from gale Banks Engineering. I got the product numbers from Stomp, the pod itself is 63114 ($34.65), the stand/mount is 63113 ($44.10). I should get mine by the end of the week. Then I can put in the rest of my gauges.

Larry

 

Sorry Jim, I forgot the phone number.

1 800 601-8072

 

The ID on the IC lines is 1.8mm I believe and the non IC's were 2mm ID.
The delivery valves were different (longer) so the line ID was not only larger but the lines stood off more and hence had slightly different shape at the pump end.

Stomp, I am curious to see how you make out with the larger inejctor nozzles....if the pump does not suffer volume loss (unusually large) and/or pressure loss then perhaps no other change to the fill time will be needed ....it is a curiosity though...

On the other hand I sent our friend an email...I've asked for 2 kits....now all I gotta do is find someone with some good turbo combo's out there.....


pb...

 

!!!!!!!!!!!!!!!!!!!buuuuusshshshsyyyyyyy!!!!!!! what do you mean by "good turbo combo's"?

 

Well where is the sign up sheet you can put me down. It will be interesting to see what you guys can sqeeze out of the new pump. If you guys come up with some better numbers which I am sure that you will do I will have to take mine off and go back through it. I will go ahead and dyno this weekend just to see where I am at and then go from there. Thanks for the help. When you get some numbers give me a call so we can compare. It looks like our friend should have his pump back together next week. So he should have some flow numbers also.


Jim,

Those are the part numbers for the Banks four gauge pod. It is a two piece pod.

NeedMoPower,

I was going to change out the lines since I have that spare motor, but I have not yet heard that I will see an increase in power. My mechanic tried some bigger lines on his second gen and he went back to his stock ones. So maybe when I run out of things to try I will try them. I have some other projects in the works so I should be busy for a while. It would be great to see what your old pump is going to put out on the test stand. My old pump was a little sick. I am still scratching my head over that one.
