Are there many horror stories of the diff breaking from launching the Z? On the S2000 forum there were always people worried about launching the car because the diff is pretty weak.

Is this something the Z is known for also?

 

no, but if you plan on going big hp i'd look into upgrading the diff

 

You'll get a better and, more importantly, accurate response if you post in the Drag sub-forum. One of the first things that will go is the axle or CV joints. Granted, that's if you're at a sticky track, on slicks and launching @ 5K+ rpms.

Even then with relatively "stock" hp at the wheels (240 ish) your axle and diff should be fine. You just have to remember to preload the drivetrain.

Not sure. Buy a 350z and try it.

 

Lol, davidv. Kenpo is getting a convertible z...

 

yeah if u pre load it so it doesn't slam when u launch it should be fine. .unless you beef up the TQ. .cause TQ is what makes the car take off. .peeps need to remember HP's for the long run. ..

think of it like them fools who do burn outs. .same concept. but they slam the drive train into motion and something will give sooner or later. . .

 

If you're worried about breaking differentials with a high-powered car, upgrading the whole driveline is a prerequsite anyways IMO. And that's just one of the many systems you'll have to upgrade if you're fast enough to be "breaking"diffs".

 

its not the speed thats gonna break them. .it's the force of power at one time being slammed through the drive train. .I would update the axles. .and deff change diff fluid every 15K if im going to be racing. .

 

Yeah I have a roadster on the way. I just wanted to know what to look out for. I don't plan on too much track time but its good to know the weak points.

But thanks for the great response that helped a lot lol.

 

A simple firmware flash should bring the axles up to date.

 

Members do get crazy at the dragstrip with 10 inch slicks. And yes they break stuff. But street tires on the street and a little fun at a stop light every now and then will be fine.

 

haha i realized i wrote that. . .

but you can DL the update at www.350zecuupdate.com~~burn the image to a CD and load it into your CD player. .should take 15 minutes max. .then your ready to slam through the gears at launch!!!

 

I don't plan on beefing the car up yet. I just got worried because so many people were talking about breaking diffs on the stock power of the S2000. Thats a good sign not a lot people have bad experience.

 

Site must be down for maintenance

 

s2k compared to a Z. .is like a go cart compared to an indy car... .

speaking about it they should of called the roadster a Z2k

 

preload and just be careful, feel your car and you will know what it will be able to handle and what it wont be able to

 

what does preload mean?

 

There are several explanations in the drag racing forum. For me pre-loading the drive train with a manual transmission makes little sense.
