again, gear boxes dont make power, only better optimize the hp that you have. the max you can utilize is what ever the max hp is, or the area under the curve dictated by gear spacing, and the range of speeds used.
so, if we agree that the top race cars in the world, like a GT3 cup car have certain ratios we could use, lets use those ratios and replace all the gears. Then, to answer the one question regarding ability to change at the track, that could be answered with the change of a ring and pinion at the track. this is REALLY shaving hairs in the club racing world. much more better time and money spent on making more hp. (much bigger payoff in performance for the $) and telemetry systems to maximize efforts of the driver.
And, finally, sometimes more shifting is not better, expecially with the 928 gear boxes being kind of fikel to work with . ever drive a 996??? now thats a gear box!! (or a bmw!)
what we really need is a 7 speed paddle shifter!!!

6 speed conversion is doable. 2-3 and 4-5 gear lines will almost definitelly change to 1-2, 3-4 and 5-6 but I would expect feel to be generally much better. Thinking it quickly, gate will be:
Code:
2 4 6 |_|_| | | | 1 3 5
- Total conversion price clearly cheaper than Motodyne pricing as less non stock parts are needed.
- No need to make any mods to body, at least not to late models. Wouldn't have it any other way. Though not 100% sure yet of early years.
- Box availability much much better than any 928 manual box ever was or will be.
- Custom gearings not readily available AFAIK but possibly easier and cheaper to make than on 928 manual box, both for individual gears and final drive.
Have it all figures out, on paper. Not ready or willing to say anything more at this time.

What kind of cooling are you using for your three-speed with that much power?
I would think that a lower stall converter might help the trans?

Hopefully that fixes my problem, and I am sure that sooner or later, especially with the following that the Shark has, someone will build a better, viable replacement for the 928.

To put in perspective.. what's the cost of building a 600HP 928?
I'm seeing a stroker with S/C, headers, xpipe and dual exhuast. Thinking that's $30K right there. Plus what the 928 cost itself. $10K for a 6-speed? Why not at that point? It's obviously not an investment car but an expensive weekend play thing.

you could spend the 10,000 on better bang for the buck, besides the 6 speed that in a best case, woud only buy you about 8% more ave hp to the wheels by better utilizing the HP curve.
might be better to build an engine with a flatter hp curve of 600hp, that way, you could shift less with the 5 speed and still have the same gains. im sure that kind of set of mods to the engine, since you already spent 30k on it, would not cost more than 10,000, and you would have a better engine too.

It would be nice to have an overdrive in the 4sp auto. I just got back from vacation and I had an Expedition for a week--and it toodled around the highway at 75 mph at around 2k rpms. The engine doesn't need to turn so fast when you're just cruising on the highway, and that would help fuel economy.

Danglerb, you know I used to think you had diarria of the mouth (given your post count), but it looks like you swing brass ***** where ever you go!

"12 customers with 4 suppliers fighting over who gets to supply them"
Hard to believe that a market of 12 units sold would be so coveted as to warrant that kind of scrambling. If I was a supplier looking to sell maybe 20 of these, I'd pay someone so I wouldn't have to do it.

Dangler, the reply to his crap is this:
You have been trying to sell this for 6 years. You have to date sold ZERO units. Everyone in the world knows you are dangling a carrot to steal yet more money from unsuspecting folks who have not had the benefit of seeing your history. Post ONE successful instal/sale here as a reference for all to see. How about the several lawsuits that have been over and over listed against you for scammiing people's money. Post those too ....

Guys, It's been fun but I have to leave you now.
I am off to trade my 928 in on a new 996. I had not realized the "Ghetto" appeal of the 928 prior to buying. Sorry guys, but I have to keep up appearances and what not. After all, I'd hate to be kicked out of the yacht club... Guess I have to sell my 32' RV as well. At $120K it's technically still just a trailer, which makes me white trash whilst I own it...And my 29' cabin cruiser as well. Maybe then once I own a 996 I can order the Motodyeing 928 transmition to mount on my wall as a trophy to how darn rich I am...
