My Polo Gt-g40-g60

Depends what wide belt kit you get. Some are massive and you get new bigger cogs too. Cost a fortune though.

What you sending it to jabba for?

[djtez]

It has a wide belt on the standard cog atm 11/12mm either or

Is it worth me
Paying the 200 euros for wide cog and 20mm belt.


I was sending the charger to jabba to have it overhauled. Service with new bearings and seals..

[PeteG40]

i've never heard of an 11mm belt snapping. plus a 20mm wide one will only sit 11-12,mm on the top shaft!

[djtez]

im just chasing the best,
Too many times have a wasted money on doing the cheaper option and something go wrong..

my understanding is the the 20mm belts come complete with two wider cogs to match ..

[PeteG40]

they are wider cogs.  But the top shaft that the cogs bolt on to isnt any longer if you know what i mean

[djtez]

ah yes, the belt covers the cog but the cog does not fully cover the shaft...

it is there for only bolted on and possibly making more strain on the top shaft bearing ?

[PeteG40]

plus rpm dont answer the phone or emails... so unless you can get elsewhere???

[djtez]

Gonna trust your judgement here ..

Ill just replace the 11/12mm belt on it !

[Jezza-7]

That rs outlet, if you run a fmic your best off getting the 165 degree one.

Also the inlet that that they sell, can get cheaper on ebay.

[djtez]

does the g40 inlet collar not fit ? .. meaning are the bolt distances the samE?

coz i have a 80mm+ inlet collar on my R1 ..

[Jezza-7]

The g60 inlet collars i have seen are to fit hoses that are 90mm. Mine is 76mm and i dont think it will fit.

[djtez]

aw well..

i saw the 90mm on ebay.de !

also max rpm has them!

[djtez]

Basically im looking for advise on the MAP sensor situation ..

im aware of 250 & 300kps

from this information ..
A G40 charger will produce: 566ccm³ per rotation
A G60 charger will produce: 860ccm³ per rotation

860 / 566 = 1.519  (51%) more flow ...

so say for instance my car was to make 14psi on 65mm pulley ..
would that make this 14 x 1.519 = 21.2psi ... (1.463bar) ..

ive seen on most motor-talk.de discussion that g60 chargers making 1.6 bar in the 1300cc ..

should a go up to 300kpa.. are there any downfalls ? .. .


Thank you!

[dub-disaster]

im running 22 psi with a 250kpa map sensor which is pretty much up to its limit you can run a 300kpa map sensor but you will loose the reseloution on it.Think youd probably get away with a 250kpa but the person mapping your car should have the finial say in this

[djtez]

Dub please explain loose resolution ?

im kinda Sh*tt*n out on using a 65mm pulley atm ..

the more a read the more a get scared !
