4age/ze - Race Harmonic Balancers from $320

[maj]

GZE pulley is just a dual row 4AG pulley but the inside row diameter is different to accommodate the SC.

Harmonically dampened GZE pullies are hard to come by and only second hand, new ones like T3 are aluminum only. 175mm would be great but requires a smaller idler pulley also. T3 recommend a 4AG NA alternator pulley, flipped backwards and shimmed out a touch. Otherwise 164mm is the largest bolt on upgrade without any further modification.
Not sure if there's much market for them since 4AGTE is a common conversion these days, but if you wanna make a batch I'll definitely put my hand up for one.

Yep will look into it and get some pricings.

I got a stock GZE pully in the shed if you need measurements etc Barry.

[Billzilla]

I'm quite interested in that pulley with the trigger teeth & gear hanging off it.

yep will get pricing up as soon as everything is finalised.

A 'dual key' option would be go nicely with the 9A cranks...

[Bazda]

These are dual key, but thats up to you if you want to use it.

[Bazda]

Bump, putting together this order now guys, let me know if you want to grab a pulley.
There are no options yet for gilmour drives.

We can do 4agze pulleys just need 1 to measure the diameter again as i lost all my measurements.

[Stolic]

any indication on the GZE pully $$$ ?

Next week hopefully!

Hi very keen on a 4AGZE one. Will it be possible to select the diameter of the supercharger part?
(Or maybe come to a consensus that everybody goes for an over-sized unit?)

Nick.

What size pulley would everyone want on a 4agze?
175mm being the largest for 14psi (then you will need a smaller tensioner pulley and a longer belt.)

Most companies range from 165-175mm. I would prob go for the largest you can fit..

Pricing is up for the double row.
Lead time is 5 weeks to manufacture.

We can add 4agze ones if people want them!

I would say 170mm.

This basically spins the SC at its 10k rpm limit at engine redline ( 170/125 x 7500rpm = 10,200 supercharger rpm )

Hi barry can you please get me a price for a 2 row, 5pk x 135mm harmonic balancer with a 35.10 ID
Let me know if you need more measuments or a sample (suit 7m)

Thanks
