can anybody give me an explanation of where these springs are in the pump or possible a pic/diagram-sounds like a good idea. any info helps!

look there,, pretty good explantion there, with pictures,,, but they install springs,,, not just the washers,, but its all about the samething,, just dont remove any springs at all. Hope this helps you

 

well i adjusted the bar shorter today but did nothing for the rpms, and now its getting caught up in the rpms. neutral rev the rpms get hung up around 1500 and in geare its absolutley solid, no hang ups, still only pulls to abot 2800, and free rev to 3000... what else is there to help this besides saving my pennies and buyingg that 4k gsk that i have been dieing to get along with the valve springs that is going to happen later this fall...

 

You could try tighten your springs one click! if you have em too loose, you need higher idle screw and that is waht causes hanging rpm!
to fix: tighten your springsm lower the idle!

and then,
there is a WOT stop screw, you could turn that one in! (a 10 mm nut holds it tight!)
on that nut is a plastic ring, just remove that with a flat screw driver!
its a little hard to get there!

oh, just to tell you, this washer mod is NOT like a 4k GSK! its more like a 3k or could be a little less (never had a 3k only 4!)

but still a 96 schould rev well past 3000.


is it popping at that rpm? if you, have other issues, timing and overflow valve

 

And to the top!!!!!!!

"We used a set of needle nose pliers this time" - being careful not to squeeze them together and booger up the threads. If I was gonna do a bunch of these I'd just use a pair I didn't care about and put a dab of weld on the joint.[/QUOTE]

In response to the above mentioned tool for adjusting the nut, I took a Wood borer, [flat one] that was 5/8" wide, it has a point in the middle for starting to drill the hole, and ground it off, and then continued further, about a 1/4" deeper, and a 1/4" wide, or so, [so the stud will fit] and then shaved just a little off the sides to fit the nut outside slot dia.. This works great cause it is longer, and the top has a hex on it so it will not turn in the drill. This is the size of a 5/32" socket that just bearly fits, and you can use a nut driver on it, or use one of those tiny wenches, called, Ignition wenches, to turn it. I found that it worked great. but make sure it has the HEX top on it.
Now you have a specalty tool. I don't know what else you would use it on.

i cut down an old wood chisle so that it fit around the stud, the handle gave me enough to grab to turn it easy. definate hats off to this mod. worked great on my 96

 

same here tightend the nuts and wammm... revs to 3200 pulling hard...

 

Has any one checked there mileage after doing this MOD?? I know the fun of doing the mod and to get the kick you recieve, I am courious. More go less throttle. Seems logicale.

mine has not changed unless i stay in pedal real hard for a long time... it wont change the mileage unless you consitently run at 3k rpm.... the higher ur rpms the less mileage you will get.....

 

I just put this mod in my truck. It revs to at least 3800 and to 3500 in gear. I'm not man enough to push it anymore. My EGTs are up too. Before I couldn't hit 1300 WOT, now I can hit 1450 and still climbing. I have one question though. The pedal is really touch, especially around 1500-2100 RPMs. Would loosing the springs a click clear this up without loosing too much rpms. I really don't want to loose the top end, but I don't want a touch throttle either. Any ideas?

 

mine does the same thing, i was just gong to post this question.

 

Yep. If you loosen up the springs it will get your throttle less touchy, and you will loose a few rpm's, but how much depends on how much you loosen them.

you do loose quit a bit of rpms.... i had mine a liitle loose and this did not clear up on my 96 but then i tightend them and gained 500 rpms...

 

12vram, who started this thread, would be a better source of info because he found this mod. he would be able to answere the question about this mod a little better thanany one else, IMO.

 

Gunracer1 started this thread at my prompting because his original post outlining the mod was only brief.
So it seemed like a good idea to get the word out in detail. We all owe gunracer1 a big thanks for this mod.
Is 12vram the same bloke? I don't recall seeing anything posted about this mod until gunracer1 came out with it.
