Giles pump!

[Mrphish89]

Excuse my language, but where the Jesus do I get one from? I live in Worcester, england and I've looked on the Internet! What's the difference between a giles pump and a gov mod pump from www.justcaddys.com for my 1.6d! Also, just by turning the smoke screw, will I find an increase in power/performance slightly? Thanks!

A governor modded pump sort of just changes the fueling curve, and sometimes makes a nice easy driving car into a less predictable menace. And you have to change your previous driving style most times. I don't think it adds very much overall power, it just mostly brings the power in sooner, as opposed to a longer stretching stock powerband. But some people like the change initially, some keep it, and some go back to stock settings.

Tinkering with the fuel screw (turning it inwards) increases the amount of fueling. It can add some power - but its usually very minimal unless the setting was previously way too the leanest scale. The exchange of decreased economy and increased black smoking isn't worth too much on an NA diesel.

Giles SuperUber rebuilds produce as much as 50% increase in overall horsepower. Higher economy. And operate smoothly.
In one particular dyno'd experiment, it produced about 90% increase in overall horsepower on a very weak 1.6 NA.

Giles. That is Giles PERIOD.

The gov mod is alot better than what is discribed above if done correctly. 8V of fury did a new edition of it. Stick to that or get Giles to do some work you won't be disappointed.

[Mrphish89]

8 valves of fury? Is he a member or something? How do you mean he did a new edition? Of the pump or the how-to guide of adjusting it? Thanks!

just do the good old fashioned gov mod. anyone can do it. i can do it in under a half hour by smell alone. hahaha.

my diesels turn about 6200 because of it.

[Mrphish89]

How do you do the gov mod? Is there a how-to on here or something? You can come and do it for me fr some beers if ou want?

that is an awesome write up on how to shim the governor the RIGHT WAY. a single stainless nut is what i use for shims.. you can use washers, but i like how the nut fits about perfectly around the shaft, and works so great.

follow these directions.. i mean follow them too. this is the correct way to do everything. your pump will work great if you do all that it says to do.

idk how so many people do the gov mod and can never get there pump to run ever again, i just dont get it.

Gov mod is fantastic and really wakes these cars up - mine would barely spin past 3K before I did it.  Now I've been up in to the high 4's without the pump cutting off fuel - fantastic difference.  Really though that's all the governor mod does, it removes the high RPM limit that's built in to the pumps.  It doesn't really add anything more than that.  It's a GREAT starting point and will definitely improve your overall driving experience, but don't expect any real changes in fuel economy or low end power.

Giles on the other hand is giving you a pump that isn't even close to stock.  He builds his pumps to allow for far more dynamic advance than they did stock (one of the problems we have with our pumps is they don't have enough advance at higher RPMs so we're actually injecting fuel too late to be useful)... I'm fairly certain he's using a different camplate, possibly changes to the pump head, LDA, you name it.  What you get from him is a pump that's built to support fueling at high RPM and injects the fuel when it's actually needed.  The price is the only killer, but in terms of $/hp probably the only cheaper thing to do is an intercooler (which if you're planning on running a Giles pump you should do first anyhow)

[Mrphish89]

Thanks!!!! how much does a Giles pump cost? I was reading about the governor mod and it said something about there being no rev limiter and basically anyone could jump in yourcar and kill it?!

[regcheeseman]

Hello bud!

The rev limiter will be a natural thing as the pump reaches it's limit - or your ears cannot stand the pain of an over revved engine.

Giles pumps are huge amounts of money especially with import costs - it's money that may well be better spent elsewhere.

I'm sure there are people that will do gov mods for you in the UK, I've done three this week

As for that post you were linked to, it showed a very manky worn US pump with small differences to your UK spec pump*, there are better guides with better pictures

If you are running an AAZ for instance, there is NO idle spring.

[Mrphish89]

Ahhh thanks for the reply! Im running a flat ad a pancake 1.6D. So maybe I should save my pennies for an engine conversion?! I was just hopeful of getting more power from my little block without boost! :/

[R.O.R-2.0]

you can get a bit more power out of an n/a, but the easiest way to get lots more power is with boost. theres plenty of us running high-teens low-twentys of boost.. i see about 22psi on a good hard pull. and i have a stock-from-VW long block. nothing special. even a fiber head gasket still. and gasser head bolts..

[regcheeseman]

In the US they spend silly money on just buying their TD motors, we can pick them up for £150, you have to bear that in mind when gettin advice on here

A giles pump could cost as much as an engine in the US, so whacking a  Giles pump on an NA makes sense, for only a small power/driveability improvement. However when we can pick up a turbo diesel engine for peanuts and get a massive power hike - it's a no brainer.

[jack's lack]

I spent approx. 750 USD on my N/A giles pump, and within 3 years I had swapped in a 1.9L Turbo engine spending another 1,200USD on a giles rebuild of that pump. The improvement of the N/A giles pump over stock was remarkable, however it was NOTHING like going to a turbo engine. In hindsight I would have done better just putting the money in the turbo build from the start. That is what I would suggest you do, and if reg cheese man is right it, and turbo D's are that much cheaper on your side of the pond, then I would say it is a no-brainer.

I can't say enough nice things about my dealings with Giles, but if it is power that you are after go turbo first. Any of these engines with about 20psi and fueling to match will be plenty quick for most of us save a brave few who push these things to the brink of insanity.

cheers, and good luck
