read that page then try and tell me LSD doesnt help at the track

LSD helps at the track, END OF STORY

 

my frind has lsd and he boggs down and looses boost so i dont know good tires on non lsd may be better safer to but i dont know. do you have lsd? if so the 14.8 should so it dont help much!

 

nope i dont have lsd wise ass

 

haha. that was a wise ass comment on his part... but worded kind of retardedly

emm... how much does the LSD weigh? that could be a factor in 1/4 times aswell. (im sorry if thats a dumb question, but i have no knowledge on lsd's)

wish i had one just for handling

 

like 2 1/2 lbs

 

You do relize the only way to settle this is to take a stock Cobalt with out LSD and run it a bunch, then install LSD and run it again a bunch in the same day.

I would imagine it does help but not enough on a 14 sec car to really matter.

 

Thats at the drag strip at least, on the autocross its completely different. The LSD car will own the other.

 

gah ... the lsd is a performance part that adds performance under certain conditions and rarely if ever makes the car lose power. end game lsd is better ... man im tired

 

If my non LSD SS can cut a 1.9X 60ft on street tires then show me an LSD'd SS cutting 1.8's and I'll bite the bullet and buy it.

 

^ ^ ^ Werd

Trust me , the G85's have EVERY BIT AS MUCH trouble hooking up at the dragstrip .

 

LSD is only helpful if one tire is getting less traction then the other... like when you're in a hard turn and the car is pushing hard on the inside wheel. This should not happen on a straight launch at the dragstrip, unless you're launching with one tire in the dirt or something.

 

It will save your front tires as well

 

It's not for drag racing, it's for auto-x...that is what lsd is best for, turns...

 

Man some of you guys dont get it. It is not impossible to get a good launch with both tires gripping with a car without LSD. but drag racing is about consistency. and you really want to be on the throttle as much as possible and maintain traction which all would agree with. latter on down the 1/4 it does not matter anymore we just mat the accelerator. real drag racers have a spool....this makes a solid axle... two steps better than a LSD. steps for a diff is OPEN (most of us have), LSD (some have the stock one is super), Locker (works like a spool but can operate as an open diff...best of both worlds), and then spool (competition only yep trailer your car to the track).

I see so many guys with open diff who post I did a 15.2 then a 14.6 and the once I got a 14.3. They think it is all driving,but it is not. It is also inconsistant traction. once you got very good traction and another time is was not so good. Drag racing is more about consistency. How good are you at getting the same very best time all day. The LSD is going to help in eliminating that traction differential and as far as I am concerned is needed in everyone of our cars and should have been.

Cant believe it. oh well. I think you have all the info here to make an informed decision.

 

Yeah but it is easier with an LSD. you have two tires consistantly working at the same time finding traction and not just one. and to boot the one tire is the tire with the least traction as power will travel out the tire with least resistance/traction.

 

Agreed..... the performance gains is super obvious in this type of racing. to say its not for drag racing..... read my other post....

 

ITs about consistancy. A well preped track and surface definitely reduce your troubles. streets are never preped so you are at a disadvantage... it takes just one dusty tire to blow your start (dusty from the street).

 

I'm cutting better 60'fters w/NO LSD then those WITH LSD. I see no greater benefit unless your pushing serious power to the wheels.

 

A car with LSD in THEORY is better than a car without it. You can't argue that point and if you do, your an idiot. All of you guys that say "I'm faster than my friend and he has LSD", that proves nothing more than driver ability.

 

I will say this, LSD was not built by the hands of god. I no doubt say that LSD is better then a car without it but too many people use it as a basis of better performance out of the box when simply it doesn't..

 

LSD is bad for you, end of story.

 

the lsd is not the end all of diff. products but not having one is in theory worse even if only messured in microscopic terms.

edit: i think people are feeling that everone is making fun of them for not having one. if you can get awesome times without an lsd, imagine had you had one!

 

Well I don't think there is any doubt that having a limited slip is beneficial...the question is spending $1000+ on the unit and another $1000+ for install worth it for us non-G85ers? Well unless I'm into Auto-X, I don't think it is. As far as I'm concerned that kind of money can be spent else where. I've had my fair share of bad 60 ft's, but I've also cut some consistant 2.0's, and 2.1's on street tires at both HRP and HMP here in Houston...so unless spending over $2k will net me better 60fts, I'll be alright w/ my open differential.

 

An lsd is certainly better than no lsd and Vivid is an awesome shop.


It may not make much of a difference while our cars are mostly stock, but once the wheel hop factor is taken out by suspension mods and a good amount more power is under the hood, it'll be noticable.

 

oh and an lsd wont increase tire life ... so far everyone I have seen that has one has their tires bald *cough* vendian
