The looming question in our minds becomes how much is something like this gear going to be worth to you guys, and how many of them do we really need to make?

We know how much it will cost to have it reproduced, and seriously doubt it would be worth the effort to do it, especially on an individual basis. As with everything, if we do a run of something the costs drop significantly. Regardless, it will not be cheap, and you can fully expect the costs to be appraoching $500 ea.

If enough people want one we could be interested in making them, that is why we acquired the gear, but after discussing it with our machinists, it seems we'll need a run of at least 5 units to keep the cost within reason, and figured their would be some difficulty getting 5 guys that would spend the money.

So you tell us, is this something we can get support for?

I know machining costs....but...

500 is astronomic....150 would be a price i'd go for instantly.(its a max of 10HP and a min of 0...this is not much.)

As well as 180 for that strut bar....way too much....i'd go for it for half a price.

I'm sure that if you drop your prices many people will buy and you will be more gained over time.

It is a fairly small market of 924 guys who run updated spark systems (MSD or something similar) which it seems you would need to get any benefit out of the adjustable cam gear.

Whatever you say cheif

FYI We spoke to Franco over a year ago, and got the gear a few months ago from a board member here so you can stop with the attack anytime.

Are you in the military by chance OutOfTheBox? Just curious.

Oh and more for the record, we offered to remake these gears becasue we can, and to do it at cost. I simply pointed out that it will be more involved, and thus more costly, than you think.

i think all that is needed for this job...of reproducing a cam gear would be:

1. Exact material properties: steel type and density for weights and weel....exact elasticity coeficients for the springs [this from Franco]
2. Exact drawings with exact sizing [this from Franco]
3. A pile of metal that coresponds with the ones specified [this from shop]
4. A good machinist willing to spend a day on this piece.

A friend of mine that has a Corrado G60 had a smaller supercharger pulley made out of aluminium for 35 EUR thats less than 50$

Yes that is simple to make...a cam gear has teeth and needs more work.
But machine work would NOT cost more than 150$ MAX add another 50$ for the pile of metal you use. and there it is...200$

Am i missing something ?

$500 is at cost in 2006 when Franco was selling them for $300 for profit just 3-4 years ago? Was there some period of hyperinflation in the US that I missed?

Isn't there a forsale/wanted forum on here. You know, since you're trying to sell us something, again...

Anyway, I'm not sure of what dizzy could be swapped that would retard as a function of rpm, as they're always setup to advance. Maybe you can turn something upside down?

You would have to make the full advance rpm on the franco wheel the same point as full retard on the dizzy. Although that point sounds to be just about the same anyway.

Moral of the story - I wouldn't rule out being able to fidle with the stock dizzy to work backwards so you can avoid going to a stand-alone crank trigger / coil pack ignition.

You other world guys should start a buisness.

Last time I checked it's more like 75 - 100 per hour.

So as you stated lets say its a day - hemm 8 hours - at 75 thats 600.00. Now considering everyone I know charges a minimum of 250.00 to set it up in Cad/Cam well gee whiz beaver - thats sure sounds like 850.00 to me.

Wait I know lets say its 5 hours as stated but at 100.00 an hour - well thats 500. Each - plus the setup fee. Anyway you want to do it - I dont know a single machinest that charges less than 75.00 and hour for anything this complicated - its a time and materials gig. Unless you talk large quanties - cause the shop could be making more money making a hundred of something else than farting around making 5 of something.

Now the same shops will do setup for free if you its a large quantity order. Even if you can get the digitizing done free - you still have either a minimal order or time and materials on small stuff.

Any Monkey with a Lathe can make a pulley.

Most shops send stuff off to a gear cutter - or if you are lucky and find a shop that has the multi axis machine and can set it up and do it - fantastic.

Either way most shops are busy with other work - try motivating them to tie up their machines to make the bits for 5 of these. They will rake you over the coals.

500 now is comparable to 320 then. Let alone whatever the final price befor production ceased.

Plus Franco made them in mass quantities - that is always cheaper.

Hemm and ah Nick you need to read son - you are so good at quoting people why dont you quote Sid - he didnt say its for said he said we could be persuaded - its speculative at best.

He said we discussed it with machinist - shops local to both of us - and its not cheap to do something like this.

This is the whole reason when I was talking about it I didnt mention the Franco gear specifically - cause it turns in to a cluster F--k with people saying I can have this made here or there for peanuts. Great maybe your machinst will build it for a slap on the back and a cold one - fantastic.

Then get-r-done.

Don't talk about it - go get it done. I will buy from anyone that has the best quality and the best price in that order.
