Like the title says, whats a rear end that would hold 2000 hp?

Obviously the ford 9" solid axle can be put in a vette, but then one loses the independent susupension and handling of having the flexible output shafts.

I thought it was the ford 9" rear or nothing, but then i came across this photo and it got me thinking...




This car is a +200,000 dollar car, custom ordered and built
http://cgi.ebay.com/ebaymotors/Chevr...1%7C240%3A1308

It says in the listing it is a dana 44 irs rear end i believe? Or is that the suspansion only?

So heres my point...

Why cant we (or maybe someone already has) build a rear end setup that utilizes a ford 9" rear, or something like this... but KEEP the torque tube concept where it is kept regid to the motor. In addition, make it rigid to the frame of the car as well...

And then also have the U joints and flexible rear axle with independent suspension.

Like i said, maybe something like this already exists, but it seems on this forum, with our torque tubes and all, we rarely come across rear ends like these.

This thread is to discuss all rear end options.... looking towards putting in a powerglide and an OD as well. Not sure yet if the powerglide would be front mounted, or if i would put it out back like the ECS kit allows us to do.

Or maybe there is a rear diff that will hold up under 2000hp that im not aware of? Thanks guys

 

The torque tube idea can include the "BOX" idea, or tube frame that goes around a trans, rear diff, and mounts to the motor... ive seen setups like these before.

Also interested if anyone has ever attempted to make a much heavier duty torque tube using a thicker aluminum pipe up the middle, or even going some heavier metal?

I thought about taking another, larger diameter aluminum pipe, and slicing it length wise, and adding a half a pipe to the under half of the already existant torque tube and welding it in place at the 2 housing ends. Suggestions of bracing or strengthening the torque tube are also welcome.

 

This is the TT I run on my car...

 

irun4cops i have a 9" center section with the best parts that money can buy in it for sale brand new in box from moser 950+shippin to you door.. Just thought i would throw it out there

 

I run that same setup in my 99 6-speed.

 

so does the stock torque tube fit around that beefy drive shaft? I would guess no, but thats why im asking.

As far as this kit stainless40cal is trying to sell for 950, what does it entail? Im not looking to pull the trigger on anything yet, im just doing some homework for my next build.
(I feel the economy has only begun to fail, and prices will be dropping further in the next few years)

How much power can a built up stock casing limited slip rear diff hold? Ive been told for 1500hp+, we need something different like the 9" rear end. I have heard the tradeoff will be that with the solid rear axle of a ford 9", then handling of the car in the curves will be horrible. Im trying to find something that keeps turning handling high, but still holds plenty of power.

 

perhaps ive been using the wrong lingo... when i was saying torque tube earlier, i meant the bell housing that is hollow, and runs from the motor back to the transmission. I have seen these sheered in a spiral fashion once they are put under too much torque. This is what i was talking about beefing up. What upgrades exist for it?

 

ECS makes the drive shaft and yes it fits into the stock torque tube.

 

checked out mosers site a bit ago after getting some time since stainles40cal mentioned them. They too have the 9" solid rear axle assemblies... so here again is my point, does the 9" rear end exist, in the format of the picture of the vette at the top of this thread, where there are the cv or U joints connecting flxible shafts... and is that what you already have stainless that you are trying to sell? If so, what does it bolt up to as far as a trans goes? What rear gear ratio does it have? And what do you hook to it as far as half shafts or axles go? Thanks buddy

 

wicked, how much power is that pictured shaft rated for? Where did you guys buy yours and how much do they cost? What other mods are needed, they look longer than the stock one right below it, no?

 

You aren't the sharpest knife in the drawer are you? Look at the flange to flange length and the are the exact same size.

 

I think you should just get a funny car with a vette shell.

 

How much you want to spend?

They can custom make you a IRS setup that will bolt into your car and is based off a 9" center section. There products are truly top notch!!!!!

 

 

Now thats very interesting right there for $4,295
Of course that set up won't work, but something like that may.

 

I sent them an email to see if this is up their alley.

 

Good idea.

 

Ive seen that setup installed and they are currently doing a custom one off setup for a friend of mines camaro, kind of a sponsor deal for him but would be very pricy, but as I said, top notch.

If you want to play, you got to pay... Guess it depends on how badly you really want to keep the IRS...

 

what do you guys think the purpose is to moving the brakes to the inside like that? versus, doing it as they did with the rear end in the vette i pictured in the first post?

I can see that the heidts way of doing it looks a bit more stout, but I like the setup of the first car I pictured, but would want to use heavier duty connecting rods for the suspension than they used.

I agree on giving these companies a call, they both would know all the tradeoffs probably to the different aproaches. I was going to give them a ring today, but got too tied up with the gf, lawyers and my web design guy.

 

sorry bout that... i noticed it was the same length, but the lack of the U joints threw me, so with the U joints on there, i wondered if it changed the geometry.
