problem with axle in high hp miata
what about the axles in high hp miata .
my target is 550-600 hp and i dont know if i put drag radial tire have any broke axle ??? |
the trans and diff will break first.. and the only way to get that power is with FMs stroker and a built motor..
|
i have rx7 tranny and cusco diff and FM stroker built motor .
see in my new st up ... |
CEO you are askin questions about stuff that most people haven't come close to doing, sooo if i were you i would go talk to that guy that has the 600hp drag miata. thats probably where you'll find your answers. good luck with your project.

Email Rob at Flipside. He runs a full RX7 Turbo II rear diff, axles and hubs. His email is exit5@comcast.net

Might as well as throw a ford 8inch in it. Properly setup it shouldn't matter on the track if you have a IRS or Live axle.
|
Yeah, when there are two companies out there making rear sub-frames/diff. mounting assemblies and custom cv axles specifically for mounting Ford 7.5" and 8.8" rear-ends to the Miata...I really don't see the point in mounting the 8" RX-7 Turbo II rear-end to the Miata. Unless you have more free time than free money, and someone gives you a free TII rear-end...then, maybe.

motoworx on m.net says he's cracking the 7" diff case before breaking any other Miata parts. He's running a nissan trans with the 7" rear and half shafts. The diff is modified with a pinion bushing/mount rather than using the ppf.

I wonder if it's his mount then? If it were mounted to a PPF, then the tranny, driveshaft, and diff would all move together. They kind of "twist" or rotate just a bit. But since the mounting points are isolated, the items don't move in unison, causing additional stress then failure?
|
where i can find this 7'' rear??
|
94+
|
Or you can get a 9" ThunderBird Rear end. Common for Monster Miata's. And Drag Mustangs!
|
The last vette to use a PPF was the C4; with the C5 and C6 and their rear-mounted trannies, they use torque-tubes to connect the engine to transaxle.

I installed a TII diff and starting to get ready to look into a stronger trans for my turbo miata. The TII diff install is pretty time consuming, but only cost me $200. However I machined the hubs down with help of friends at no cost. The swap to TII diff would not be that hard due to fact that can purchase hubs from miataroadster. Then you only have to get driveshaft fabbed and mount for diff. However other rearends may be better options for gearing but that depends on what you want to use your car for.

I broke over 2 Dozen axles in my old Miata drag racing it at 450hp! I eventually had Driveshaft Shop build me a custom set of Axles for the car. I sold them to some dude in Vegas and never heard from him again.
|
I was just trying to think of where I saw someone with axles from the driveshaft shop lol. Do you recall how much those ran?
