BTW...that slider in the center is also why the carbon fiber driveshaft is only 2 lbs lighter than stock. That slider has to be made out of steel in order to not break.
Yea, I think if like 7 or 8 of us all bought them the price would be lowered and he would actually get on it and do the design since he will know there is a market for them.jeremy haakonso said:sounds very promising!!! if this guy could make a driveshaft that saves 9 lbs and still have the same strength and durability of the stock unit, i would be really interested in buying one. i'm sure many other people would be interested also, keep us posted
Kick ASS!!! Yes, please get me the number. Thanks.deavenly1 said:Tony, out here in ca, There is a little place called inland empire drive line. They are pretty well known to the high powered domestic guy's and are doing a lot of import stuff now also, I talked to them and they say they have done several for 2jz's and no breakage. They quoted me like 3xx.00 and that's in aluminum. I will look for the # if your interested.

He has tested out the strongest aluminum available and has done testing on it but it broke after about 50 cycles. The problem lies where the Supra has a direct bolt on to the transmission instead of the driveshaft sliding into the tranny. That means that the slide deal has to be built in the driveshaft and that is where all the weight comes from.
His next project is going to be trying to build a 3.25 inch aluminum driveshaft for the Supra and if he can get it done we will have a driveshaft that will only be about 11lbs compared to the stock weight of 20lbs!!! That would be very cool. Everyone needs to call them and say that they need one so it will motivate him more to do one....if not really that many people want one than he really has no reason to hurry up and design it.
What he has right now is a chromoly driveshaft that will hold all the power and is only a couple lbs lighter but also eliminates the carrier bearing in the center, which will transfer more power after eliminating this piece. He also has a replacement for the rear rubber piece that bolts to the rear end...you don't have to replace this but he says that if you are making over 1000hp that stock piece won't last very long. Also, I think this replacement piece will transfer more power because it won't be moving back all the time during load transfers.
I am still not exactly sure what I am going to do but the chromoly driveshaft is $400 and the end piece is $200. He said that the end piece is so high because of the time that is in building one of those. He said also that he can have a driveshaft made within 2 days.
Just thought that everyone might like to know that about their Supra driveshaft system.
Their will still be a slider in the driveshaft. The operation will be the same. They say the slider is supposed to be for elimination of noise, but they say going to a one piece is elimination of noise in itself. A buddy of mine eliminated his center carrier bearing in his 300zx and he doesn't notice anymore noise than before. I will have to find out a little more about this. As far as hp increase by eliminating this...don't know.Javeman said:what did he say the use of the center carrier bearing is for?
if there is no slider between the tranny and diff.... what kind of side effects will eliminating the center carrier bearing cause?
you say that this shop has done aluminum driveshafts for the supras before. what kind of weight savings do they say can be seen with this one over the stock driveshaft? i'm very interested, and if the weight savings is 7 lbs or more i would most likely buy one too.deavenly1 said:Tony, Sorry I didn't get back sooner, i haven't checked the site in a couple of day's. here is the #.909-390-3030. Let me know what you think, I will go ahead and get mine done to, I think they need one to go off anyway's, (Length, Ect.)
Just noticed that I made a mistake when writing this....when I said the slider is an elimination for noise I was actually talking about the center carrier bearing, sorry for the confusion.TT_6SPD_95 said:
