curious if anyone has it

I saw a post where a guy installed one, but he is also building his engine so I don't think it is running yet.

 

hmmmmmmmmm i see

 

Yes they are a good thing. They put one in a SCC project car and the thing worked great. Why do you want one though? LSD don't do **** for performance...

 

do you seriously believe that? It may not lower a quarter mile time but will greatly improve cornering and wet road performance.

 

There was a thread a few days ago with DAVE B and all these guys talking about acceleration and stuff and that LSD didn't do much for the MAX. Do I believe it? I don't really care. Will I get a phantom LSD when I do a swap? Hell yes...

 

i guess you mean straight line performance....

cause around turns i would think it helps alot

 

i dont understand why you say that its a good thing and it worked great for them but it doesnt do anything....

 

I was talking about straight line performance. I saw quite a few MAXIMAS do peel outs and 2 times did I see one tire mark behind them. It was always 2 straight burnt rubber lines. In the corners and such LSDs are great...

 

yeah thats what i thought...what did SCC say about them?

 

I'll try to scan the page...

I emailed the company to find out if their specified '98+ Maxima manual tranny version of the product would work for '95-'97 models.

They do not have one spec'ed for '95-'97 manuals, but I see no reason why if it works in a '98, it wouldn't work in all 4th Gens, since the internals are the same. The quafieamerica LSD is one part# for '95-'99, so I'm not sure why this would be any different

Will let you all know what kind of response I get from them. . .

I'm getting mine installed in November together with my VB and torque
converter.

 

TQ Converter for an auto max? Since when?

 

Yes, that's right 5 speed manuals have fly wheels and auto's have torque converter's since they invented auto transmissions. All automatic's have torque converter's. Anyway when you start to shop around you will see for yourself if you wan't to go SC, Nitrous or Turbo you need to beef up that auto.

 

No, I don't believe my LSD does much for launching purposes at the track. I can feel it work when cornering, but the I30 VSLD is not a true 50/50 limited slip like some aftermarket ones. I have heard it was a 70/30, but that was just second hand info that I don't know to be true.

 

I'll have my Phantom Grip on once my clutch or tranny starts dying (I have 68K miles on my stock drivetrain). My 2nd tranny is at my friend's shop and the Phantom Grip is going to be installed this week. I have my Fidanza and Exedy Stage 1 clutch in my garage, but I want to do the install all at once. Can't wait, but I thought until I need to replace something. BTW, I went with the upgraded Green springs.

As for performance, it should totally improve the cornering, but also the straight-line. The tires should hook better instead of torque-steering all over the place. I don't know if it's a huge improvement, but I'll take what I can get.

 

Eh...sort of....

 

I think I have read some bad things about it somewhere. You might try posting in the Si vs. All section of clubsi.com. It puts pressure on something and can cause it to wear prematurely I believe, as well as not working all the time. I could be wrong though.

 

Right. The automatic engine has what's called a flex plate, which replaces the flywheel and bolts up to the crank and to the torque convertor. The flex plate is much thinner and lighter than a flywheel. The inertia of a heavy flywheel is used to smooth out firing pulses in order to make the engine idle and run smoothly. The inertia of the TC and also the viscous damping in the tranny fluid in the TC do the same in the auto tranny.

 

I believe the "spider" gears are what you're refering to. The Phantom Grip somehow puts loads on the spider gears which in turn makes the open differential perform like an LSD to a point. It's almost like a locker in some regards. And yes, the problems with the Phantom Grips are becoming more widespread after people have used them for a year or so. I wouldn't risk it and if I wanted a LSD, I'd invest in something like the Quafie or I30 VLSD.

The VLSD ratio is about 70/60 to 30/40 depending on conditions, clutch pack effectiveness, condition of the clutch pack fluid, etc. VLSD also takes a short time to react to the "peg-leg" spin because it takes time for the clutch pack fluid to warm up and engage the clutches. It still works okay in the turns, but in the straight line the time it takes to start working is of little benefit in the 1st 60'.

I have yet to hear of a Phantom Grip “LSD” user, that was properly installed with the upgraded green springs, to have any bad experiences. I’ve seen a few Saturn and Neon owners have the diff blown apart, but that was due to a weld problem only for those cars. The only other case I know of is a turbo H23 prelude that was putting down 350 whp. The whole tranny blew (from the diff) at the drag strip. It was stable at 350whp, but he increased his boost…actually there’s a video floating around of that night. Since then, he upgraded the tranny and shoved a Quaife in there. I think for my purposes, the Phantom Grip will be just fine.

I bought an extra 5-speed tranny from a 99 for only $160 shipped and my friend at a transmission shop is doing the install, so this is much cheaper than a Quaife.

 

I stand corrected. . .& educated. Thanks.

 

right right.

 

Phantom's had some good writeups on NPM including a test of straightline accel.

I've also heard it's a sturdy product from some autox buddies - no matter which springs they've used.

 

my 95se 5 speed leaves dual solid tire strips 2 1/2 car lents rpms permitting does that mean i have vlsd? not once have i spun only one tire at a time

 

Nope. My Maxima does the same thing. Some cars are more prone to "peg leg" launching because of torque (or lack of it), lack of weight over the tires, and unequalized axle lengths.

If you really want to test and see if you have an LSD, go around a 90 degree turn on a wet street in 1st and punch it. If the inside tire spins dramatically then you don't have a LSD.

so in this case lsd is good for you? :x

 

what the hell is NO2?

 

its number 2 my second car...

 

oh i see.
