Limited Slip? some say yes and some say no

[1Gkid]

So I have a 1G with front wheel drive. Awder has told me that Limited Slip would be in my best interest at some time in the future. I have had others tell me that i will not need it. I plan on getting about 360 hp to the wheels by the time I am done with my vehicle. I will also most likely be getting a 50 trim turbo. I think with this much power i will need limited slip. Is it a good idea to get limited slip?

Depends if you like your 1 wheel burn outs, if not i would get it.

Get it. Not only will you actually be able to get out of the hole a little faster, but you'll be able to pull in a sraighter line than without it.

It will also reduce the amount of torquesteer you have.

I have a BM tranny LSD *insert* installed in the front diff of my AWD. No where near as effective as a full on LSD, but I can tell the difference (even with the AWD) that it pulls straighter and harder out of the hole and at a roll. Then again though, I was having issues overpowering the Viscous coupler and just roasting the fronts.

Laying two even stripes is far better than laying one insanely long stripe. You don't look like an idiot either when you try to race at Bandi or somewhere and do a one-wheel-wonder in the burnout box.

Also. Get at least a set of Prothane inserts for the motor mounts. Controlling the engine roll is by far the most effective means to getting rid of wheelhop and transferring power to the ground.

I would have that as a mod later down the road.

I had a 20G in my FWD and had quite a few mods before thinking that would be a worthwhile mod due to cost.

By the time I got to the point of wanting the quaife, I decided to part the car and get an AWD.

AHH, All wheel or no wheel, at least thats what I say. But we have to make due with what we have.

[mac214]

I agree and that is why I didn't say get rid of the FWD and go AWD.

I just wouldn't make a LSD one of my first mods. However, everyone has their own ideas on mod paths so he really just needs to decide where the priorities lie depending on what he wants out of the car.

I am not saying no to the LSD only that I would wait a while before getting one.

Not to jack the thread, but.....

Marcus, you are running a Phantom Grip type lsd in the front right?

How well does it work? How about in cornering?

Nah, it's not hijacking only because it's a direct question on how it performs.

It's no where near an actual LSD on how it performs.

It's totally unnoticeable in the corners as it doesn't lock the axle up tight enough to do anything in that sense.

In the 2004 season, I was having serous issues getting out of the hole at Bandi. I couldn't do anything to get myself anything lower than a 1.8 60' time (even that was a miracle). I was just spinning far too much to make any progress.

After that, I installed the LSD insert and a factory center diff for the early part of the 2005 season. I was able to drop the 60' times to 1.8's consistently, but still nowhere near where I needed them to be. Torquesteer going down the strip was reduced a ton too. It didn't seem like it had a tendency to light up either front tire.

Mid season 2005, I swapped the center diff (and tranny) for a welded unit. With the welded center and LSD combo, I was able to pull a 1.521 60' time on the slicks (limited to the slipping 2600 clutch). On street tires (Nitto NT555), I managed a 1.639 60' as a best with consistent high 1.6's to low 1.7's. All of these were done with a 2600/street disk combo clutch that was SEVERELY slipping throughout 1st gear.

For the money and ease of installation, the LSD insert *is* worthwhile for those who want something better than an open diff, but don't want to shell out for a full on LSD. If you buy one, there are two versions available. One with normal springs and one with the heavier springs. Be sure to get the version with the heavy springs. Be cautioned though. These do wear out FAR faster than an LSD. There is nothing to protect the insert or the spider gears from wear.

We have one of these installed in the Mirage (FWD and slicked) as well.

Keep in mind that all of this has been with an AWD car. A FWD car should see greater effects of the insert though. I still have yet to try it with the Mirage.


Now I'm probably off topic...
