I was wondering if you were going to have durability issues in that regard. The GM FWD axle form factor is not suited to the abuse of driving with locked diff and a lot of traction. The inner CV joint splines in the transmission are the second weak point in the axles... following the outer CV joint splines in the wheel hubs.

Yes Will, these axles are the ones that came with the car when I bought it since 2008, so you can imagine the abuse they've had over the years. I'm going to re-weld the diff and save some money. The Driveshaft Shop is near my town and they make axles for the Fiero, at only $700 pair. Is there an upgrade I can use as an less expensive alternative?

Interesting... they claim to be able to make any configuration. I wonder if they use bespoke inner CV joint tri-pots or what. The configuration pictured uses an intermediate shaft, or maybe is for a 4T65E-HD trans, but if they can make the Fiero configuration, that would work. Stock, the CV joint stub will shear before the splines strip out of the side gears, but I imagine that situation is reversed with the DSS axles.
I have a pair of the old Ecotec racing program axle flanges for 94mm bolt-on CV joints... A few sets are still available for $550ish, but you also need to run them with an intermediate shaft and custom axles, which bumps costs up a lot more than just running DSS axles.

 This is one of the runs I did that day. It only shows power to 5891rpm but at you can see the line is a straight line. I had the runs up to 6000rpm because I was concentrating on smoothing out that dip at lower rpms. This one specifically shows 245whp @ 5891.
Today I'm tuning for the upgraded pump and injector and at low to mid rpm 1/4 to 1/2 throttle the car is wicked torky! And in the 3rd low to mid take off test and it had no problem lighting off the new soft Toyos then this happens!
 All I did was laught!! The funny thing is that I picked 2 new axles earlier today because I'm going next weekend to the track!

I think that's the first time I've seen a 3.4 V6 snap an axle.
Got Torque?

No fins, they are for low to mid range improvement. This build is from mid to top. [This message has been edited by La fiera (edited 11-27-2017).]
