so diameters all remain the same. its just the pulley offset that changes.

sounds easy enough pending availability... which doesnt seem that plentiful.

[takai]

I would actually be inclined to increase the diameter of the water pump and alternator, and decrease the diameter of the crank pulley.
Underdrive ftw.

http://www.piesau.com.au/ - This is where i found the pulleys
Go onto their site and then click "shop online" located at the top right of the page
Click timing belts and timing pulleys on the left menu then click timing pulleys
Now click metric pulleys. In this menu they have all sizes and widths, you'd be looking at the T5 pulleys as the teeth spacing is about the same as a timing belt and under this section they have pulleys to accept 25mm belts. They run from 10 to 60 teeth.

Heres a few places round sydney that make belts to size also

Anyways heres a link to a whole bunch of belt makers

I also found this mob at kings park that make belts to size http://www.rydell.com.au/

P.s thanks for the rep - rep makes me feel good

would it be ok to use all the same style ie the enclosed pulleys not the open cogged ones?

what are the advantages of using a gilmer belt system???

and do ya get that fsssss belt whine? i love that sound!

this is all about getting the wine mate that marvellous marvellous wine,deep 2.5" mandrel burble,wining belts and blow off valve make for one very crazy sounding TA22

What is this underdrive you speek of? what are the repercussions of changing the diameter of the pulleys?


Also sorry guys forgot to mention that I had made contact with Pies before and he has quoted 300 a pulley...mmm not good farkhen...I am going to rare spares and asking them ever so nicly to let me measure up the size of the standard sets for holden etc..

thanks all this has become quite an informative thread..

i think it basically spins accessories a bit slower (that wont cause issues ie overheating etc) to save on parasitic loss from spinning off the crank sapping precious hp/kw.

i think parasitic is the right word? im sure takai knows

Actual performance characteristics are the freeing of 5-8 wheel horsepower (it was once needed to spin your heavy stock pulley – now it can be used to spin your wheels!) due to increased engine efficiency and less rotating mass.
This pulley installs using your stock belts and hardware for an easy, effective and trouble-free bolt on... Can be installed in approximately 20 minutes! Comes with fully detailed and photo illustrated step by step instructions.

Stock pulley weighs 5.6 lbs vs AutoSpeed 1.5 lbsOne owner said... "Its like when you turn OFF the A/C switch, you immediately feel the engine is much more lively and responsive, a must have mod."

Why would they be $300 a pulley? unless your talking custom pulleys made up.

I was more thinking towards buying their off the shelf pulleys in the sizes best suited for our applications and then getting them milled and have keyways put into them. However i may have come into an interesting little problem. I was speaking to Fernando from 3rds at blacktown earlier and he said it would be like $20 to get the two alternator and water pump pulleys machined and keyed (thats $20 for each one), but when i asked him about the harmonic balancer he said he wasnt sure if that could be machined for two reasons, one being it is balanced - although im sure it could be balanced again, and also the rubber inside the balancer would prob get a lil rooted from machining either from heat or whatever.
He then told me that there are places which can make you custom harmonic balancers but he said that for him it was like $600 and he knows the guy and runs his stickers and so on so for us that means like $900 and upwards. So that kinda sucks.

Could someone please clarify if the harmonic balancers on the 3t have rubber in the guts of them and also if each pulley is removable, sorry i dont know this i just havent pulled mine off.

Clarification and input appreciated

And the underdrive as spoken of above means either running a larger crank pulley or smaller alternator and/or water pump pulleys, the result being that the smaller a pulley the faster it spins so if you make the latter 2 smaller then they will produce more electricity and pump more water. Downside being that you may cavitate the water at high rpm, and you may burn out the alternator if you spin it too fast. Personally i am leaning towards running as close to stock sizes as possible

off the subject a bit


but is that a supercharger i can see?

i've just got my hands on one and will need to go through the whole process off pulleys and all that as well

could you please pm me if you have any advice, tips and hints that would be useful

thanks

[LeeRoy]

Craig, 2 problems:
1. The motor pictured is a 4a and i dont see a supercharger, i do however see a water pump, alternator, and harmonic balancer along with 2 cam pulleys
2. The engines we are talking about are 3t-gte's and in celicas

Unless your using a blown 3t???

If not i think your out of luck for possibly using our pulleys if we even get em cause theyll be different.

Back to totally horn sounding whining noises we could all just gets 2nd hand rooted belts for next to nothing, they'll howl like a scalded cat ... or not and just say we did.

Yep 300 a pulley,thats a cnc machined cad drawn up mofo from scratch...as I said if we can just get the blanks done its a piece of piss,even the aluminium to make the 200mm pulley is 60 bucks,the guy at one off performance components at Mc graths hill said he can make anything fit the harmonic balancer he said its the least of our worries,its the pulley sizes thats the prob...

[LeeRoy]

Nath, what im trying to say is can't we just buy the off the shelf pulleys and modify them? cause thats gunna cost like 1/4 as much as fully custom ones.
http://www.piesau.com.au/shop/en-us/dept_27.html
This page has their pulleys already made and they say $18 on them, we should just buy some of them and get them machined and keyed to fit the alternator and water pump, thats my 2c

I'm seriously sceptical about machining the balancer but cause that rubber will shit itself if it gets too much heat, then all hell will break loose motor wise

Its actually the reverse, an overdrive kit will do as you have suggested. An underdrive kit will actually run the ancillaries slower one to not have as much parasitic loss, but more importantly it reduces the chance of alternator bearing death and water pump cavitation.
Ill post more after i drop my girlfriend home.

[takai]

Ok, just had a look at the pies site, and i think ill do some measuring over the weekend and order some on monday to test anyway. If they dont turn out to be suitable they will make nice paperweights or doorstops (just like those smallport pistons).

With the harmonic balancer i would be inclined to machine it completely out of alloy, and get it balanced to say 10,000rpm or 12,000rpm, and there are a few places which will do that. When i go out to my machinists on Tuesday or Thursday i will have a chat to him about making up some Gilmer drive crank pulleys and see how much it would cost. May even take out a sample crank pully.
However, i would be intending to get them machined up for a 10-15% reduction in ancillaries speed, which may not be so good for those of you intending to use these pulleys on the road.
