Engine/Transmission (1994 - 1998) GSK AND "0" PLATE??

[Forrest]

ok guys, ive been doing some searching and what ive came up with is a #0 plate wont work well with a 3k or 4k gsk--why?



i also have a #8 and a home ground #100--would either of these work better with the gsk?



i havent installed a gsk YET but i will be soon and just needing input.



thanks, mike

No problem with the 4k gsk & the #0 plate in my 215 pump.

I just installed a 4k gsk in my 215 pump with a 0 plate today. ... . I likey!

This is also why I stick with the stock afc spring in the 215 pump and not one of the lighter versions...



Bingo... ... I use that spring too. If you have a stock injectored 215 pump the middle spring like the one in a 180 pump works good if you set it up at about 25 psi.

Not to hijack the thread, but Matthug mentioned that the 5 plate/gsk was a bad combination. Since that's what I'm running just wondering what's wrong with it.

It doesn't happen to everybody that runs that combo, it's just the most common.

What exactly is the problem that comes up with those plates and spring kits? Do they stop fueling up top or something?

 

[Matthug]

Not necessarily stop fueling but it becomes irradical for some reason with the shape of certain plates.

 

[Forrest Nearing]

the problem is it takes so long to get off the nose of the plate and into the fueling...



I had a #6 on my 97 w/ a 4k gsk... with the wastegate plugged, you could watch the boost sit at 35psi untill about 2500rpm, and then it would go up to 42psi...



so I wasn't getting full fuel till 2500!!!



grinding the plate flat fixed that... I had 45psi from about 1900 on up



so that's the problem, the lever arm travels slower, so plates w/ a big nose don't work well w/ GSK's...



don't listen to Jim, his pump and injectors flow more down low w/ a #6 than a 215 pump w/ 370's and no plate! LOL!

I machined a couple of plates that i can bolt the cam plate and afc up to. It puts them in the same position as being on the pump. Hook regulated air to it and you can watch the afc arm move forward and make adjustments to allow the governor arm to reach the plate. I had two pumps when I built it. A 913 that I got from PDR, and a brand new 887 pump that i had bumped at II. Neither afc was allowing the arm to reach the plate. The new afc was still moving forward at 60psi with the spring loosened all the way up. I made a new spring and machined a few things and finally got it to go all the way forward. Night and day difference.
