there are FAQ's but people just dont know what spring to shim most of the time.

but that pic you posted up this time, its perfect. thats the way to do it.

we really need to clear up the confusion about governor mods in the FAQ...

If you take the lever in both hands and pull it youll see how it works, at WOT the 2 smaller are fully compressed anyway, shimming them makes no gain imo, only ruins part throttle and idle control.

My bad Kevo, thanks for clearing it up  ;D

So in my pics is what NOT to do or you WILL have driveability issues with a solid shimmed INTERMEDIATE spring.

This pic (from a considerable consensus) is the proper method on how to do the "Governor Mod" correctly! Sorry for the confusion in my last post! lol This will effectively allow the pump to feel that it has a stiffer main spring and allow for more fuel at all rpm ranges under load.

p.s are there actually any definitive DIY's out there that properly outline the steps needed and the correct shims to put in the correct spots? lol

DING DING DING!  We have a winner!!

Hope you don't mind but I've copied the pic and stuck in on my own server so there's another one out there (seems people's Imageshack links always go dead by the time I want to read the articles again) - so for posterity and all you future thread searchers here's the pic again just in case:

Np Vanbcguy. MIGHT I SUGGEST copying this entire thread I have put together to your server as well.

http://www.vwdiesel.net/forum/index.php?topic=24323.0

I took all the broken threads on here and vortex.. all the pictures describing the best method.. and information from other sources as well, and compiled them in to a nice little thread in our FAQ section :)

Does anybody have experience with what will happen when shimming the main spring with something solid?

There was question raised.. and i wish to find an answer for it for my governor thread :)

TIA!

This pic any good? Theres loads more random pump part pics on my photobucket for anyone wanting to use them, 'del635'.
Shimming the governor solid, messes up the lda? ie no smoke control?

How many mm's of washers would you say you added to the Main spring on the right? How is it to drive? any irregularities on acceleration, cruising, up hills? Good power through the entire RPM range? seems, you've almost got the main srping shimmed right solid..

I am very interested to hear of your experience with it this way. :)

No problems at all at part throttle at any load, the rpms do not hang at all either between gears. There is still travel in the main spring, cant remember exactly how much tbh maybe about a 1/4 of original and there is also much more tension, I thought this was needed for the lda otherwise there would be nothing for it to hold back on off boost. The cars pulls harder above 3k rpm at full throttle much different to the non shimmed lever where power just tailed away to nothing.
I used to have the smaller spring shimmed as well there was no noticable power difference at full throttle and at part throttle it was hard work keeping the car at a constant speed, you had to constantly adjust the pedal back forward it was only after this did I really understand just what the governor is doing at all rpms/loads its not just a rev limiter.
The one thing I dont like about the gov mod is the lack of no load speed limitation, eg I was trying to pull another car which was stuck in snow and when my wheels lost grip a quick blip of the pedal saw over 6k rpm! :o I cant let anyone drive my car either as it would take a matter of seconds to blow the engine to pieces but all in with a bit of sense it is an excellent mod for free hp.

good point about having no rev limit at all - and others driving your car...

i guess it wouldnt be a huge job to wire a relay into the stop solenoid, trigerred by an electronic overspeed signal (either from tach or something else). cut fuel at specific rpm.....

im about this far shimmed up too. (~3/16") i really cant tell any difference driving the car, other than it has alot more power and turns about 7000 rpms after the mod.

it blew alot more blackness after the mod.

I just did mine today.  I'll see how it turns out once i have the engine in the car.  Except i shimmed mine at the end of the main spring.  Like in the photo above to your far right.  Hope it works out, am strongly thinking i'm going to want a tach for this thing.

to bad you didn't wait till after you had the engine in, could have saw the gains on the butt-dyno lol

How did it go? did you use a new seal for the pump top?
