Is anyone else keeping up with the progress on this awesome transmission?

DKOV not the other link.

Not really.  

Sounds like it'll be a beautiful transmission when complete, tested, etc., but to be honest I got tired of wading past the way-to-go's, I want's, and top-of-page bumps to the real content some time ago.   :(

Sounds nice!  For the driving I do the four speed that I have (3:65) is fine.  Anything more would be overkill.

If I get the urge, I may take it apart and mix the gears from the 4 speeds for a better overall match.

Tranny is not the problem it is those lousy axle shafts that hurt or so I have been told and told and told... Dan

It’s a whole transaxle kit not just a transmission.  Axles are good for 450+ too. ;)

But I hear that you have a driver abuse problem with your axles.  Poor things? ;D

It sounds like a dream come true!

interesting

I am not about to bad mouth anybody, but I would really rethink anything coming from DKOV, I have been hearing alot of bad things, just a heads up!

I'm waiting for testing results on DKOV before I buy anything.  But it seems that he may have been talking out of his ass, we'll see, time will tell.

I am keeping my eye on a few different transmissions in hopes that one will prove worthy, without breaking the bank.  By that I mean in the $2000 range.

is this the one that is based on the Acura NSX trans?
or something like that?  I read a few of those threads, but like Don, got tired of all the reading thru "I wants"  and  "Cool!" etc etc etc

but ONE of those threads (but which board?) did admit that they were basing it on an Acura transaxle; I THOUGHT it was an NSX.
I know a top Acura mechanic; he has helped with a racing NSX and he is a bit surprised at the hype.......... remember, he usually only sees these things in 'broken' form......
but it is interesting.  He mentioned that when they took out the 5 spd and put in the 6 spd the car's lap times (Mosport) went UP.
hmmmm.   I LIKE the idea of a 6 spd.  It just sounds so......EXOTIC. 
But........when you are separated from the next place contender by .4 seconds, then shifting time MIGHT be a consideration.  But for street, it is just fun "rowing thru the gears"!! 
should be interesting, and nice to finally have a strong trans for a manual setup.
Are you going to keep following this, Aaron?

DKOV is a dead thread.  Apparently he wasn't willing to commit what it was going to take.  He probably thought it was a good idea but can't seem to talk the manufacturer into running off a low production number.

However the Acura NSX transmission that West Coast Fiero is working on is basically just that.  An Acura NSX transmission with a custom mounting kit and new shift cables, and a bent piece of metal to weld into that spot in your frame that you have to cut to get this thing in.  Although having a kit ready made for you is nice I don’t think this one is going to be worth the price since it’s not really a custom transmission.

As for 5 speed vs 6 speed.  It would be nice for those with really powerful engines to have a larger overdrive this isn’t what the six speed does.  The gear ration on the final drive for the five speed is the same as the final drive on the six peed.  Meaning that the six speed is only good for people with really small or low powered motors.  In a comparison like this one the five speed will always out perform the six speed because of the shifting time.  Also motors with wide powerbands don’t need the extra gearing just higher gears.

The thread to watch now if you are looking for a high powered transmission is the five speed here (WCF).

But if any of you want this transmission I may be able to put in your fiero for a much better price (that’s if we can get a transmission at a decent price).

some dude that just came into my shop claim's that he bought an 88 fiero at an action in montreal and found a northstar with a saab six speed in there.
that was in 1998
and brags that the car was running 9.56 in sanair.
could he be telling the truth and anyone ever heard of this supposed car?? :-\

marc the stroker.

9.56???????????????

that is more than 'just a northstar'...........
think about how much power you need to go that fast, REGARDLESS of the trans.
Going thru that many gears on a drag strip eats up time, too.

and the super stock guys run autos to get that or else a specialty trans.
9.56???
That is 650+hp range I would guess. 

I would have to call BS on that one.  There is a Saab transmission that I’ve heard of that should work but I’ve never seen on installed.  But a six speed isn’t as fast as the five speed and that has been proven over and over again.  The best times at the track are made with a tall third and starting from zero in second gear, not first.  Expect stock northstar Fiero’s to run 12’s.

If it’s not stock anything can be done.  To get 9.5 in the ¼ mile in a fiero at about 2600 lb one would also need 700 hp at the flywheel.

Aaron; what Saab trans or car would that be, do youknow?
I am interested in checking out ANY HD transaxle in any european car.

I'm not sure, but "slammed Fiero" has looked into it.

I don't know if this will help, but how about the Pontiac Vibe? didn't it come with a 6 speed gear box??

Joe

I’m kind of done thinking about the 6 speed gear box because no one makes it with two overdrive gears.  So in the end it would be a useless gearbox for a powerful motor.  It’s probably good for those 150 hp motors though.

As far as the vibe goes, I don’t think the 6 speed was rated at much in the way of torque.  I remember guys on PFF talking about it and don’t remember it as being a good idea.

Now I’m just looking for a good five speed.  It seems like the getrag 282 is holding up okay.  All accounts of failure on that transmission seem to be saying that it’s the differential that goes first, so as long as I cut down on the spinning of tires the transmission should last fairly well.  Although it seems like I might need a transmission oil cooler.  The transmission gets a little hard to handle after track driving for a while.

I can tell you that the 282 is a good tranny. We at Race-Tech have a 93 Cavalier Z24 with a 3800 N/A Turbo. This passed season we ran the bone stock engine at 12 psi and made 430 hp to the wheels still using the untuched 282 that came with the car. The car was running 11.33 @ 127 mph.

In October we changed injectors uped the boost to 16 psi, added a LSD and a custom Racetech stage 5 clutch and made an extra 90 hp to the wheels. Since it was close to the end of the racing season we were unable to run it down the track to see how much better is would have been.

This cumming season we are still going to use the same tranny with no new changes to it, but we are going to do some mods to the engine to handel 18+ boost. Right now I'm working on giving the car a diet, its 500 lbs over weight comparied to the other cars running in the pro class.

Joe

That does make me feel better but there still is a lot less stress on that transmission just because it's on a front wheel drive car and not a rear wheel drive.  With the right tires I can lift the front end of the fiero, but I'm not about to do that because that will definitely do some damage.

Aaron

P.S. you have to do something about that sig.  It's way too big.

I forgot to mention that we have 28" x 9" slicks and still running stock drive shafts, well ok in a season we may go through two or three shafts.

Each time we are at the track we get 5 to 6 runs in may be more depending on how well we are doing, usually shafts will last 4 events so that means we get at least 20 good HARD runs in with launching the car at 6000+ RPM with a bad 60ft of 1.8

Joe

That sounds good!

This is getting a bit off topic but do you have any experiance cooling the oil in the transmission?

Aaron

Sorry Aaron, not with any manual tranny.
