Lost Bottom End With The 6x.16's

[Richie O]

NOTE: I'm led to believe that dropping the pop-pressure a little mimics advancing the injection timing event by allowing fuel flow just that much earlier. The Scheid 6x.016" EDMs are set to 3400.

Then , unless you know your own pop pressure then timing is just guessing. I have no idea what mine are set at. I assume stock pop pressure.

This is the same problem I'am having.30lbs of boost max..Slow to spool.And I can shut 4lanes of traffic down with the smoke.So this issue has to do with overfueling and timing? Ezra

I'm not having a boost problem, pegging out a 60psi gauge with teh Silver 62

When I installed mine it boosted well past 50 on the first trip. I drove directly home and backed off 2 turns. Now 42 to 43 psi.

My KSB is not hooked up for teh advance. non-IC'ed

There is your problem. You are running full advance all the time on your pump. Therefore it won't matter what you do to the timing piston once it starts and builds case presssure it will go to full advanced and stay. Basicaly you made your pump into a p-pump. Fix your KSB to work right and you should regain dynamic timing control and it should run better. The tricky part is getting it regulated so that you get the proper advance curve with your setup for optimum driveability. To just mak power leave the KSb unplugged an don't worry about how crappy it drives.

i run both my non i/c trucks with power to ksb all the time, tried both ways,bottom end/spool-up were crappy with no power to it.

I run a skipped tooth and then past the stock mark when running properly. Right now the truck is detuned slightly so I can kinda drive it untill the twins are on. I have the KSB operating as stock. My pump has no problem keeping the 6-18's pumping fuel. I would be surprised if you guys really had the fuel to over fuel the truck so much it ran poorly. Its possible but.... Right now driving my truck with the 6-18's, 14mm, and AD150 my spool up and boost is crazy fast. I just have a little s300g on right now and itll hit 45psi at 1/3 throttle. It smokes like a freight train and the EGT's are almost uncontolable. But all im really trying t say is with all the fuel it still runs fine just vastly over powers the turbo.

Your guys issue sounds like some thing totally different. My pop pressure on the injectors is basically stock so no changes there. I would bump the timing a tooth or just push it right to the head and see if it makes a difference. I do use a ton of timing normally. Even right now I have a jumped tooth and am just under the stock timing mark.

Hmmm.... I have a hobbs switch here set to come on at 15psi, I wonder if I should set that to trigger a normaly closed relay so that the KSB is activated under 15psi (most day to day driving) but it pulls power from it when I hit 15psi. That would allow me to get a good boosted 4wd launch in (I launch around 10psi) and pretty much out of the hole the ksb would deactivate and give me the timing I need.

dont know how fast the ksb works on i/c pump, on the noni/c ksb it activates real slow, i,ve pulled it and watched it move. takes about a minute to fully move one way or the other. didnt time it , just a guess. if the your ksb is the same its too slow to do what you want.

That was my understanding also. The non i/c uses a wax that needs to heat up for it to work. Not really an on off thing.

Is the IC'ed different? Are they easy to swap? Seems to me that the underhood temps might heat it up enough to make unplugging teh non-I/C'ed useless.

[KTA]

Yes swapping pumps is easy, no swapping KSB styles is not. There are many diffrences between the two internaly.

[RSWORDS]

Hooked the KSB back up and holy crap I have spool up!

But the power is WAY down... Like BIG difference. How much timing will I gain by shoving the pump to the head? will it then run like it did with teh ksb off?

[crewcabxlt]

i always run with mine hooked up, spools better for sure. even dynoed wiyh it on,maybe i should have unhooked to dyno with it unhooked ? heard its worth 20 more hp, dont know though.
