That's good news.

They should know, but I'm not sure I totally believe it. I guess we could proceed with the stock unit, knowing that it'll probably go boom sooner or later. I want us to use and enjoy this thing. :thumbs_up:

"...The RX-7's layout and structure is well suited to engine conversions. The rotary engine's eccentric shaft centerline is way up in the center of the rotary engine, dictating a much higher transmission location than that of a piston engine. The net result is that Mazda designed the RX-7 with a HUGE transmission tunnel, big enough to fit even the monster T-56 6 spd manual transmission which was used in the Viper and Corvette. The rotary engine's low torque output required Mazda to use a very heavy flywheel and a high rear gear ratio, a combination of factors that combined induce large amounts of stress on the RX-7's rear axles and hubs. Mazda planned accordingly, and designed plenty of strength into the RX-7's rear differential/axles/and hubs. Experience has shown that the stock NA RX-7 components are strong enough to withstand low 10sec 1/4mi passes, a feat that requires around 500hp. "

Well, that's interesting. . .

Kinda surprising. Well, should we test that statement?:confused:

Obviously we have no idea what the internal condition of the diff is right now. We have three options.
1 - Stay with the stock unit til it go boom
2 - Replace with T II unit (if I can determine that it's up to the task)
3 - Replace with narrowed 8.8

For now we'll go with 1, research 2, and do basic planning for 3.

Second or third pass.:pot_stir:

LOL, I love your cynasism. I say we set the over/under at 3 passes. I'll take the over :D

I say we test that statement and when/if it blows up we can say for certain it can't handle it.

I will say over, but not by much.

Under. (If I drive it first, 1 pass);)

Of course, without D/S and Axle Safety Hoops, I won't.:smack:

Ever seen what 350 HP does to a 3 1/2" Vette Halfshaft? I have. Looks like a donut/twist.:judge:
