I have searched (a little), but i can't really find out how much an LSD setup can knock off the 1/4 mile times.

Let's say you've got 2 stock H22a preludes, but one has LSD, What's the difference in time between the 2 on the 1/4??

I'm bulletproofing my H22a right now, and am hoping to make a good 400whp. I'm trying to find out if LSD is going benefit me more then it costs.

Over here in Europe it's probable going to cost around 350$ more(shipping etc etc), that's why i need to know if it;s worth it. I hardly race, but when i do i really go for it.

Can anyone give me some advice? I'd appriciate it.

 

if you really plan on putting down 400 hp to the wheels a lsd is manditory, otherwise all you will do is peg legged burnouts. make sure you go with something that will last, i cant give a brand because i havent done the research, but a lot of guys here can tell you whats up. good luck with your goal, keep us updated.

 

Go with quaife.

All that power, you'll need the traction. It's more than likely that you'll lose traction in every gear without a LSD with 400whp.

the stock transmission will put down power to the path of least resistance basically...so it'll spin one wheel if you break traction. a lsd makes sure that the wheels are spinning together...so you can put down more power sooner, without having traction be as much of an issue. this = lower 1/4 times

 

yeah i've experienced that wheelspin with my H23 turbo setup. 292 hp with 9 psi boost. Blew the rings at 13 psi while testing on the dyno.

I'm Going to do the lsd install myself, and am using the HCI import magazines as a guide hehehehe. There are no good tuners here in The Netherlands.

So basically i'm going with Quaife. Anyone ever heard of KTP LSD??I think Rage performance's civic is running that,maybe it's less expensive Any more advice always welcome.

 

The main benefit of quafie is the 100% warrenty. Blow it up on the track/strip, bring it back and get a new one

oh and the main benefit for lsd is mainly 60' times. you can easily knock off .1-.2 of an average non lsd 60'.

 

I thought LSD had a lot more benifets in handling and cornering than it did in 60 and 1/4 times...

 

depends which one you are looking for ...

a guy going down the track isnt going to notice better handling or maybe would not care for it at all ...

 

Does anyone know KTP's LSD product?? What is the price range??

How much for a Qauife unit??

Thankz

Well it does help on cornering, especially when exiting a corner. Usually the car will roll out and the inside tire will lose traction, this is where the LSD comes in and trys to eliminate the problem by distributing power equally to both drive wheels . The Prelud SH with ATTS has a similar unit but I'm not sure on the specifics.

 

But if there's eqaul power on both wheels, the car is going to have the tendancy to go forward in a corner right?? So is that really going to benefit the cornering of the car??

 

it's not always equal power. The LSD senses which wheel is slipping and applies more force to that one.

 

Last year we raced at 510whp with a stock diff and had a 1.82 60ft - this year we are at 590 whp running a Quaife. We found out that a stock diff will only run one 1/4 mile pass with this power - so the Quaife has been great for us - our 60ft is 1.79 this year. The cost last year was $895 this year the price went up.

 

I always though LSD's transfer power to the nonslipping wheels for traction, not the slipping wheel?

You are correct, but if you read carefully I said "exiting a turn."

nope my MN friend
it gives power to all drive wheels equally

atts diverts power to the outside wheel in a turn to make it spin faster to keep up with the inside wheel, so its like an lsd where it puts power to both wheels, but instead of equal power causing the wheels to want to go in a straight line, it diverts power as needed so the outside wheel can keep up with the insde which has a shorter distance to travel

in a turn an lsd disengages so that the wheels will spin like an open diff, otherwise if it were locked and both wheels getting the same power and going the same speed, the inside wheel would have to lose traction since it has to go slower than the outside wheel...

 

Yeah i know, but just to get some more info. If i can save some money i'd prefer that over all the extra costs that the LSD brings with it. If the LSD wasn't bringing down alot of 1/4 time i wouldn't buy one. But i see know it's a must for Dragrace.

Now i just need to find out what best price and options for my setup. Cause i live over here in Europe i have alot more bullshit to deal with.

Information is Ammunition.

 

quaife (torsen type) is your best bet if you want long term usage. It has a lifetime warranty and it doesn't need to have parts replaced like some LSDs (Clutch Type).
