Flaw in most of my posts they are - Convoluted:

Dictionary defines:
- also convoluted - highly involved or intricate; noting:"the Byzantine tax structure"; "convoluted legal language"; "convoluted reasoning"; "intricate needlework"; "an intricate labyrinth of refined phraseology"; "the plot was too involved"; "tortuous legal procedures"; "tortuous negotiations lasting for months"

Also see:
intricate, tortuous, tangled, involved and complex - complicated in structure; consisting of interconnected parts; "a complex set of variations based on simple melody"; "a complex mass of diverse laws and customs"
---------------------------------------------------

So guess they tend to be tortuous, long, complex and involved - such is my nature - so forgive me for that. They can also be a bit scattered - as i tend to posts various thoughts - and examples of things all in the same long post.

Well,

If you guy's can firm up on a price, i would be very intersted. If this does as it's meant too, and I've seen a lot about, a 5-8% increase in HP is not a bad thing. Especially as it is free,ie no extra boost ect. This mated to my ITB'd DTA'd 300HP motor would seem to give a nice improvement in the mid range power curve. Thats what i want!!
ESC/Sid PM me if you have more info.

Thanks,

Steve

Multi-tasking is so much fun....

So - the road block to a ACG - its affect on the Distro - solve that and its a great upgrade.

Or if you have a car that can make use of it as is - as Steve does - well then it offers and interesting solution...

Steve - your car brings up another point - a power adder - that causes a percent increase - well the more base power you have - the higher the return.

Not really, you look like back peddling jackass's that are trying more to win favor from the group than standing up for what you believe. Stick to your guns like our crew and you will actually get some respect.


umm, ok, well my924gtc. .... if you look at esc944's posts .... the other day I was reading this forum, and everytime I refreshed, esc944 had edited his original post. If you think editing posts is 'bad' and that it means you havn't 'stuck to your guns' might want to have a chat with your crew. This is why I always quote the entire relevant part of a post I'm responding too.

Oh well, go back to making yourself look bad on a public forum. In my opinion, this thread has only hurt your crew's reputation. You havn't 'won' anything. There is nothing to win.

Min - I agree with you -

Back peddling is back peddling - but going from defense and turn the other cheek to offense --- big difference.

Back peddling to look good vs. getting Nastier ... yea like those are the same thing...

Anyway:
I was clear about editing my posts - I removed one part of a post that was giving Nick such heart burn - and was very clear it was to appease the Mighty Nick...

I also corrected things and tried to reduce the sheer mass of stuff when repeating myself, rushed poor grammer - still not perfect - but I was upset and I went back and cleaned it up... I am guilty of that - but I didnt do it to win favor or show grace or some such - I did it to try and make it more readable - If you read them the first time and then went back you will see that I went from turning the other cheek to not this time... here is a little of what you are throwing at me right back at you....

Turning the tables is not back peddling -

I dont mind taking flak for that - I even posted that I edited stuff - Mark jumped on me for it too - but the point stands -

If you want to attack me then fine lets go to war. I would rather discuss things that work or dont with out all the drama.

You forget one other point - I am in business - I am on this forum cause I own these cars and love them dearly. I also want to spread the idea that you can do more with them than sell you na and upgrade to a 931.

I have said over and over I dont care who you get your parts from, add some boost, or crank it up, or convert to EFI - right along with the stuff in the performance section - i contribute both sides of the arguement when I can - and state what I believe and why -

So if I am supposed to take it and not say a word back well guess business is going to suck for me if thats what you think it means - I dont.

I remain a member of this board - same as I started who is into performance - I just happen to have gotten serious about reproducing things instead of just talking about it or reading someone lament about how they want this or that - but cant get it cause no one makes it, etc...

I personally dont give a rip about a business rep - when it comes to being human - I am a human first not an business - I am part of a business - like I keep saying - find something flawed in what we make or sell.

Find the flaws in what I have made or done and point them out - that would be great - I can learn like everyone else - including my own mistakes...

But slaping the snot out of some Jack @sses who is picking a fight with me - well sorry seems like a reasonable reaction to me -

It is an open forum - so I guess some how the whole personal attack rules are ignored - if thats the case - well you only get some many free hits...

I would rather shake it off - but after a while - well I dont pick fights - but I have been known to finish a few... verbal or otherwise...

I cant wait to see who comments on my violent nature....

Anyway - I thought we where getting back on topic...

Ok at first I thought that OotB was being helpful in providing his opinions on what he has researched but now its become more of a trolling, the pictures, editing his posts so that it doesn't say anything, kind of childish.

As of late, everything has turned into a mud slinging bitch fest, its starting to become annoying. The threads have to return back to discussion and facts, something helpful instead of this crap.

If franco gets back to me, then I will be prepared to cost the unit here.

If he doesn't then its obviously ESC944's call.

But:

I am going to get a manual adjustable;

I'd like to try making a unit were 2 solenoids attached to 2 pins on, either side of the cam shaft.

One pin would be for low rpm setting.
The other for high rpm setting.

Each pin/solenoid will only be able to select its own hole in the camshaft.

The Pins would be spring loaded to always want to engage the shaft.

But it would be physically impossible for both to be engaged at the same time.

Because of the small difference in angle(10deg), then any acceleration or deacceleration would quickly move the cam gear between its limits, WITHOUT ANY SPRINGS. .....very fast.

This device will very quickly lock in either position, without any power...Fail Safe.

Using 2 microswitches you can tell which position the cam is engaged in, and instruct which solenoid to release.

You will do this only when the motor is, for one solenoid, accelerating.
and the other solenoid, deaccelerating.

The ECU can do this, so that you barely notice a blip, the smallest drop or increase in rpm would be enough to make it switch.

Instruct ECU >>> drop rpm by 100, release solenoid.
Instruct ECU >>> increase rpm by 100, release the other solenoid.

Is microswitch1 active >>>kewl >>>pile it on.
If not the dont allow any increase in rpm, repeat.

...........

This would work and be very simple, but you would have to accelerate/deaccelerate the motor to change between settings

Very easy to do if you have a programmable ECU.

LIKE I SAID FRANCO'S GEAR IS OVERLY COMPLICATED, IF ?????we????? want that extra 10HP out of boost, but dont really care about it when boost is in.

That doesn't mean I'm knocking Franco's design, but it's his right ? and if I want a way of adjusting my cam timing, then I'll go make my own stuff.

Fortunately I dont need anybodys money, and if I loose out helping others then I wont worry, because kindness repays kindness, unless your in the performance parts business.

what ECU ?

and how do you plan on powering those switches and solenoids?

i think the franco gear is a good design and would work fine on the 924NA and 924Turbo. Anyone that can explain in fewer words (then ESC944) what would be the problem with the ignition sistem being on the other end of the shaft? and what would be necesary for these two things to work togheder?

OK, HERE IT GOES
1. As the cam gear starts to retard or advance the cam in relation to the crank it is also moving the ignition timing , The distributor is connected to the same shaft and is gear driven by the cam.

Steve we have seen a much as 60 bhp by moving the cams on a DOHC setup, but this is mostly from a badly setup up cam, in this situ , the gears will allow you to dial in the cams. Best part is the gears allows you to move your peak around variable is the best of both worlds , if you can get a rpm variable advance/retard coupled with the S60 rejoice!

Thankyou sequential that was great....i read esc944's posts and dont understand a thing....sometimes i get more confused actualy...

So you need a new ignition setup...something that will distribute spark in relation with the crank and not with the cam-shaft.

Later ROW 924s still have the distributor on the other end of the shaft but they also have that electronic ignition control, the BOSCH aluminium box in the drivers side...near the headlight bucket. Can there be made some mods so the spark will be distributed in relation with the crank and not with the cam-shaft ? I guess that using the existing distributor that is impossible...so using a digital unit that gets a signal from the flyweel or the crank pulley would do the trick...corect? Can the BOSCH aluminium box do this ? or does it need replacing ?

I would say, If you are turbocharged, first get an aftermarket Ignition System, BEFORE getting the ~$500:) automatic cam gear.

The money/time you will spend adapting your distributor to the cam gear, on top of the purchase price, will be far better spent, on an Ignition Upgrade.

Also I'm not sure of the physics of one set of flyweights controlling another.
I think their could be problems under acceleration, especially at high rpm????

Anyone????

Anyone know a Danny Williams ?

Seems this adjustable cam gear was patented only last month ?

US Patent 7007652

Hello Guy's ,
That patent is interesting , as the first centrifugal timing gear for the toofah , as purchased by myself was 17 years ago and it was already patented , by rob walker!

Applications where for
VW A1, A2 ,
Porsche 924
Audi 4 , 5 ,cyl.

Cheers!
