95 300zx TT-440 hp-Any drive line mods needed?

[garygbnj]

Car has an hd clutch. I drive it gently. Just made it 440 hp from 400 hp. Do I have any drive line concerns? Thanks

How do you know your HP numbers? Is it a guess or did you dyno? As for your question, two things
1) Your clutch should ALWAYS be the weakest point in your drivetrain, its designed to fail non-catastrophically and is a maintenance item.
2) Good condition Z32 drive-trains handle 4 digit horsepower (generally)

Some cars have CV's as fail points. Aasier to replace a CV axle than drop a transmission. Subaru I believe usually have their CV axles go before the clutch but I could be wrong. Id make sure everything is specked for the power and make sure your weak point is not your transmission itself.

No idea what you are talking about and I'd have to say in my previous experience with a number of cars, including multiple Subaru's I'd have to call BS on your claim in regards to Z32s and Subarus in particular. Going back to what I said previously "its [the clutch] designed to fail non-catastrophically". A CV failing on a Subaru (especially) a manual early model awd one has the potential to wreak havoc on the center diff if the joint fails internally. Given the possibility of the CV failing at load it has the potential to tear up the suspension/subframe/body etc. It may be that some very high HP supercars, hypercars, exotics, purposebuilt cars have the CV as a failure point but having such a designed failure point on a road car is dangerous. The bean counters at the automaker would NEVER allow something like that.

Agreed, OEM would NEVER sign off on a solution that could cause accidents or damage the vehicle further (warranty concerns) as a fail point option.
