EOI Group Purchase of 4340 steel flywheels.

[Superscan]

I have finally talked my brother to look seriously at making some light flywheels made from billet 4340 steel.

They will be of comparable weight and price to an aluminium flywheel.

They will be drilled for the 225mm clutch but will also see if they can also be done for the 240mm as well.

They will be sold through NPC Performance Clutches, who are based in Archerfield, Brisbane.

Their front page has one of the clutches my brother designed and built.

If you are GENUINELY interested in purchasing one, please post here.

Cheers.

I would be but I don't think it will fit my gearbox :(

What flywheel/clutch/gearbox setup are you currently running?

Cheers.

Had a chat with Doug (NPC) and my brother today and the result is a flywheel drilled for both the 225mm and 240mm clutch setups, with the possibility of a 250mm friction plate version for those wanting to go wild.

The flywheel should weigh in a little heavier than 5.5kgs due to the larger reinforced area required for the extra holes and the friction area of the flywheel being around 10mm thick, to allow for several resurfacings.

BTW: these are 1 piece, ie: the ring gear is cut into the flywheel then induction hardened.

It's now all down to the number of people who need them.

hmm interesting, that would fit my gearbox if those sizes were offered then. I will discuss with my builder and see if its worth investing in and get back to you. Whats the current weight of the flywheel? The stock one? I know the fidanza ones are around 3.5kg

The standard flywheel is over 10kgs.

Can I assume the flywheel is the same if:

• I'm using a W58 box?
  I'm using an RX7 box?
  I'm using a narroblock instead of a wideblock?

[jwebb2876]

Narrowblock will be smaller, dunno about the others but I'd assume so. All you'd need to do is change the clutch friction disc to suit the W5x/RX7 spline?

Yes, if you are using a Wideblock bellhousing adaptor

Can I assume the flywheel is the same if:

• I'm using an RX7 box?

Yes, if you are using the B2600 bellhousing.

Can I assume the flywheel is the same if:

• I'm using a narroblock instead of a wideblock?

No..

Doesn't seem to be much interest.. :(

Would only need 5-10 people (I'll be getting 4 for myself) to get this off the ground. Once the flywheel is made, it's on file and can be made on demand (the benefits of CNC machining).

Doug also does standard and performance clutches (funnily enough) to suit most applications.

Its the sort of thing that I would definetely buy if they were available. Unfortunately at the moment, all my money is tied up with another project.

[thrash]

mine is a narrow block :(

also, what price are we looking at? I think people tend to assume that if price is not mentioned, it's already going to be too expensive..

Price looks to be approx $430 but may be a bit lower if there is a decent number of people buying one.

I want one, I know steve with the black widebody would want one, but neither of us have the money at the moment! Maybe when tax returns come back LOL
