Question NA rear end strength??

Ok. I'm confused at the moment. I've searched on the forum and found the n/a rear end can handle something like 300hp without trouble. I've heard around town that they will only hold 190-200. Which is the case?

for most n/a mods, the rear-end will hold up. doing a turbo conversion, not so much

The car's gonna be for drift. The tires won't be too sticky, but I wonder if the stress from drifting would be too much for the rear end.

Understanbdable, but if something breaks, I don't want it to be because the part was too weak. I'd be ok with it if it was because I screwed up and the car ran into something. Though drifting on the track, there is not much to hit.

the na rear end will be fine ... hp is not an issue with drifting as the tires are already broken loose once the power is being put through them ... and for drifting i hop the tires u are using in the rear are the qquivilant to a hockey puck and a sticky tire would be a waste ... but yeah think of the application the na diff has no problum with side to side .. its the sudden power input with nowhere to go that it has trouble with ,. its been proven many a time that an na drivline will hold to quite a bit of abuse t2 stuff is over rated and just heavy ... no doubt its stronger ... but its over rated imo atleast

That's what I figured. I don't predict myself using sticky tires as, like you said, that would be a waste of money. So as long as I don't build to 400hp and use it as a drag car, it'll be fine. My goal by the way is 250.. at first.

I've managed to destroy three 7" Mazda LSD's. The Miata guys swear buy 'em, but they really don't stand up to the abuse at the 300hp+ level. The last one I killed I was launching on drag radials (not slicks). If you can get a hold of an 8", I would highly recommend it.

again ... its the direct force with the rear end that kills it .... not much in its stock form can handle 300hp plus .. even on dot drag radials they are still significantly stickier than a "drift" radial like a nankang or a pos falken witch are still preaty stickey btw .. my point is drifting does not put nearly as much stress on a diff as one would anticipate regardless of hp levles the tires are already broken loose thus needeing less power to rotate them further ,,, and much less stres on all drivetrain components minus the stupid high revs that the engine will be subject to ...

Why are Falken's "Peice of ****" 's?

And it's easier to sound intelligent when you can spell good...I do it all the time, even when I have no idea what I'm talking about! Practice + 4th grade education really does wonders!

Way to generalize all of Falken's tires from experience with their low-cost, all-season offering.

In any case, it's been said that V8 guys have been able to run their drag cars just fine on the stock rear end. If it's strong enough to handle the torque from a V8, why not a freaking rotary?

Maybe they're not making as much power as they think they are?

They are making alot more power then 95% of TII's and a **** ton more torque then most 500HP HP TII's will make. So they are making plenty of power.

The NA rear is good for 10-11 1/4 miles even with the Parts Crusher T-56 transmission.

Again, I destroyed a 7" LSD just about every time I went to the track with a car that was only running low-8s/ high-7s in the 1/8th on 205-series drag radials. 7" diffs are junk; If you're not breaking them, you're not making enough power.

It's because of your drag radials.

Most V8 guys run street tires to hit 11's and 10's. With slicks they'd shred the rears.

What are you breaking the in the diff. The worst I have seen is a broken stub shaft. My friend has 5.0l miata and 350 v8 rx-7 running mid twelves on street drag tires. Both car are using NA lsd diffs. I have a half BP na/4 port turbo with T04b @ 23psi and I have not broke yet.

Wow, you may have just taken the cake for stupidest comment that can possibly have been made in this thread. Omfg.

And just so you know, the Falken Azeni is one of the best street tires...period.

I know, but most Falken's aren't the best performing tire around.

I'm poor myself so I use Hankook KT104's, $38 a peice! And since I don't track they're fine .
