G60 Pulley sizes

[trev124]

Hi guys. couple of questions. Don’t know what size of a pulley is on my charger. Theres a superchip chip fitted to the ECU so I imagine its been upgraded. Where do you measure the pulley from and would anyone have a standard chip and pulley for sale.

Hi Trev,

A recap of your questions :

1. Don’t know what size of a pulley is on my charger. -> Get a ruling caliper and measure one of the five upstanding ribs in the middle where the belt runs on, on the outer diameter of it.
2. Theres a superchip chip fitted to the ECU so I imagine its been upgraded -> Generic modchip. What number does it state on the sticker ?
3. Where do you measure the pulley from -> Pick one of the 5 ribs in the middle and measure the outside diameter of one.
4. Would anyone have a standard chip and pulley for sale -> Have a couple of them over here, if interested. Chips are also selectable. Have a huge library of original and tuned ones.

A original pulley is giving me 79.3 millimeters as of diameter on the outer-ribs where the serpentinebelt runs. Measure up yours and report back please.

A 68mm (max semi-safe pulley to use up to 7000rpm) pulley, measures at the outer ribs in the middle 68mm. Checked it over here.

Hope this helps a bit

Greetings,

Pvl

Thanks for the help. That should clear things up abit. Will measure over the weekend.[]

Measured the pulley. It approx 66mm from the top to top of the belt Vs. Also found some numbers on the Superchip. They are G60 7246.346 11054. Any ideas what these mean.

Hi Trev,

Is it possible to measure your pulley up again, as i described from top of the upstanding teeth in the middle of the pulley to the other side of the
upstanding teeth of the pulley,while the belt is off it ? Because thats the only way to get a proper diameter readout.

If you now already measure 66mm, that will clearly not get any bigger than a 65mm or even a 62mm pulley. These pulley-sizes take the
g60-charger over it’s normal limits. This is only for low revs/hi-boost applications. Lower than 6750-7000 rpm max !!!!
for standard internal stuff.

Not to mention the crap that uk-overhaulers call ‘oem’ or oem+’ put in. Let them explain with clear facts on paper, WHY their oem+
stuff is better than the specially designed volkswagen parts that arent for sale at the dealer [] They can’t.
And to be honest, their parts are worse than originally used. They wear out your charger much sooner than the original vw-parts do.

So if you want to preserve your g-charger, i HIGHLY recommend a bigger pulley. A DECENT service, and ofcourse some proper software to go
with that, dialled in to YOUR engine.

Superchips, is just a generic software-producer that only change a few bits here and there in the chip, and in combination with small pulleys,
you’ll run the risk, when the g-charger is in very good condition that you’ll run lean and burn some pistons.

According to this website (http://www.segilu.com/Summer2001/bhp2000/Vw/vwturbo.htm), your chip is made for a vw g60-computer, using the
7246 ending in the bosch-chip-number. To be more specific, it’s boschnumber : 1267357246 (the actual original chip).
Do a google-search on this one, and be amazed, that ONLY corrado’s use this base-chip. Therefore i can safely report to you, that if you don’t
have aircon, you’re missing out on performance, as this chip is for a car with a SMALL intercooler like the golf-g60-aircon or a corrado/passat.

This chip looks great, as of the name presumes, to let you believe it’s the ultimate chip for any g60. But due to multiple car-configurations, 5-10bhp
can be obtained easily, plus some extra torque, due to the fact that cars that have larger intercoolers, can run a bit more ignition pre-advance.

I would recommend a better way, of tuning cars, and use a chip which was written for the car, as a base, and then tune it for all things that
are done to the engine. Camshafts, ported charger, higher compression, bigger bore, different exhaust, all comes into play when dialing in
a car near perfection as of software.

Could you be so kind, to also let me know what mods/options your golf has? Aircon (one of the options perhaps) is very important to state,
as that intercooler (just described) plays a major role. (robs 10bhp, tuned).

Hope to help you out a bit more, and am looking forward to your reply,

Pascal

Hello again Pascal. I was measuring the pulley from the top of the groove across the pulley to the top of the same groove with the belt off. With regards to the chip, my engine is from a G60 corrado with a small intercooler under the wing. I would be quite happy to return the car to the original chip and pulley and fit a larger intercooler later for better efficiency. Can you supply me with a standard pulley and chip.

Hi,

Thats no probs,

I’ll need some extra details, to help you out properly.

First i want to know which colour of injectors the engine currently has. Look with a flashlight inbetween the intake-collector
and the rockercover to see if they are grey or green.

Is there indeed a intercooler installed? Perhaps some pictures from under the hood will be more revealing.

A performance-chip is also possible for the original pulley. This will bring it to app. 180bhp with no extra fuel-consumption
when driving normally. But it just drives a bit better.

You may email me at : pvlg60@gmail.com

Thanks,

Pascal
