2010 Edition of the Governor Mod

[knowtwodrugs]

So has anyone tried shimming the idle spring and then adjusting the fuel screw to get more fuel at the bottom end without causing major idle headaches?

Sorry I didn't see this till now..

Messing with the idle spring doesn't seem to make sens to me.. what would it accomplish? It only provides fueling while idling.

Doing the way that is listed in this thread will increase fueling at all off idle rpm's including the bottom end.

when i wrote this I scoured the web for all the info i could find, and none of the information i found had any gains from shimming the other springs.

What size shims does seem to fit? (OD, ID)

For us metric guys I shimmed up my governor with M4 washers (ID 4.3mm, OD 9.0mm), perfect fit and now my mk1 GTD revs like a maniac

shimming the idle, or intermediate spring, will make it very hard to drive..

the idle spring is tiny, you can almost breathe on it too hard and compress it. why would you want to shim it?

the only spring that needs to be shimmed, is the main spring. thats what takes care of the upper RPM fuel cut anyways..

those 2 other springs are fully compressed by like 3k rpms..

and as was stated, washers/nuts work good for shimming the governor.. i think i used m6 or m8 nuts to shim mine.

Just updated the bottom of the original post! CHECK IT OUT

In the new pics, that looks like the Eco pump, no?

[8v-of-fury]

Not an Eco, my engine is Non-Turbo. that is a 1991 N/a motor in my 84.

its amazing the difference even doing it to a n/a huh?

my diesel would ALMOST keep up with my GTI when i cranked up the fuel, did the gov mod, opened up the intake, and put a header on it..

Well if you think about it, taking away the fueling issues.. It is still a Fuel Injected 1.6 motor. It is producing probably about the same as a 1.6 FI gas.  Intake, Exhaust, and a port job should make some OK power out of one. A giles pump on all of that would be off the hook.

diesel has WAY more energy in it than gasoline, you should be able to build MORE power with a diesel, based on just the fuel.. but it doesnt work that way because diesel burns so slow.

Oh god, now that there's more pictures I'm feeling the pressure to do this mod.

*orders pump seal kit and mans up*

[8v-of-fury]

I kid you not, 80km/h in 2nd gear was absolutely no feat for it.. And I think that's like 5500 rpm's. At that point you could feel that the engine could still make power.. But the pump was physically topping out

[Fredrikkk]

I see you shimmed the main spring completely solid. I recon that gives fueling all the way until the rollers skip, but how does that compare to say, shimming it with a couple of washers instead. I'd like to have fuller fueling up until at least 5,000 so I can support a bigger turbo easier

The only problem with this mod is that you pretty quickly realize that you need a better clutch
