well i was goin thru craigslist and seen a ad where a guy says he welds differentials and has been doin it for a long time on many cars and never had a problem.. has anyone heard of this b4? its suppose to make both wheels spin just as a lsd.. is it even possible to do anythin like this to a honda trans?

 

no they wont spin like an lsd cause an lsd will disengage going around corners.... it will be more like a spool but weaker... your better off buying just a spool and putting it in your trans they go for aroud $300 ... but good luck turning or lack there of cause you wont turn

 

i think it would be possible. either way if the guy charged what this kinda thing would be worth for a quality job you could just go buy an OBX LSD and be done with it. especially for a D-series

 

A welded diff will suck for turning, and is not very dependable.

 

youd probably be better off calling up Hmotors and buying one of there trans with the optional lsd in it (i dont know how much the trans is) to get lsd its like $300-350 depending on the trans... i orderd my B16a with a clutch lsd .. $300 for an lsd thats better then quife and obx... give them a call see what they say

oem lsd is NOT better than quaife haha

 

a clutch lsd? the way a quaif works is wich ever wheel (in turning) has less traction the power goes to... the way a clutch works is it basicly "clicks" or disengages, engages,disengages, engages so pretty much one wheel spins, both wheels spin, one wheel spins, one wheel spins.... yo uget it? on a launch with a clutch both wheels WILL spin with a gear type lsd both wheels MAY spin its not guarnteed

 

yah i thought it wudnt work either.. im not plannin to get that, it was sumthn that jus made me wonder if its possible.. the guy charges 60 bucks.. so that kinda explains how much the job is worth.. but i didnt think lsd is that cheap thru hmotors.. thanks for that info!

It would also suck because of tire wear. You would eat up your tires while turning!
Welding the diff is more popular in offroad vehicles. It is a lot cheaper than buying a locker.

 

true that lockers are expensive... yeah through Hmotors its 300 ontop of what they charge... just check them out.. you gotta call tho its not on there site... im not sure if they do sell them i assume so becasue they sell long blocks so i would think theyll sell just trans

 

its only good for rwd cars. beside diff are only on rwd machines. hondas are front!

 

no, diffs are in the front as well... limited slip differential...

 

my bad didnt explain my self rigth, your rigth. but either way welding its only done on rwd cars as far as i know.

Half right.

There's a differential in FWD trans's - but it's nowhere near the same, there's no pumpkin differential on a FWD trans.

@ OP:
This is a good trick for making a RWD car faster at the track. You weld the gears together in the differential and it basically gives you a solid rear axle. It's not an LSD per-se as the wheel with the greatest traction isn't powered but rather both wheels are ALWAYS powered.

When you take bends though the inner wheel will lock.

When I was 14 or 15 I used to drive this 4sp manual '87 Jeep CJ7 to the end of the road and back (dead end road) and when I pulled a U turn at the end of the road in 4WD during the winter (manual locking hubs) I thought the axle was hung up or something when I pulled that U turn and the inner wheel locked, scared the **** outta me, thought I broke something .

My friend's got a race camaro and he has a locked rear axle and when you take bends in his car the inner wheel locks every 10ft or so (depending on how sharp the bend is) and it chirps a bit.

It's a good trick for RWD drag cars, not exactly useful for a civic as you'll run into some driveability issues.

LSD = Power to the wheel w/ most traction
Welded Diff = Both wheels always powered
Regular Diff = Power to the wheel w/ least resistance (least traction)

^^^^^^^^ I'm pretty sure that's the way the story goes.

 

yeah pretty much but regular diff.... open diff... cause there is really no "regular" diff...

LSDs dont disengage going around corners. If you have a 2 way lsd (clutchpack), then it's like having full lock on decel or accel. There's only a very imcremental change in wheel speeds around corners. Usually used for drifting. BAD idea for FWD.

1.5 way (clutchpack or viscous) will disengage halfway under decel. It will have some good give around corners. Companies use this for stock setups because it's pretty smooth. If you accelerate around the corner, it goes into lock...how much it goes into lock depends on the strength (holding power) of the LSD. Not a very good idea for FWD.

Honda's 1 way torsen LSDs (used in the B series, K series, and F series, H series, ETC...everything but VTM 4WD vehicles like the CRV or MDX) are very smooth...the "disengagement" around corners is not true, though. You want an LSD to keep both tires spinning the same speed as you go around the corner. Torsen means "torque sensing" or "torque multiplying". The only way to have an open diff under accel is if you lift 1 wheel off the ground. This is because if you multiply anything by 0, you still get 0. 1 way diffs only work on acceleration. They are open under decel. This is why Miatas and S2000s are so hard to drift...err...besides torque issues.

Lockup of any LSD depends on how much you push the other wheel to go faster. LSD means "limited slip diff". So there's a LIMTED amount of slippage around corners.

A welded diff will cause unwanted tire hop around turns, and very bad understeer. Both wheels will have NO choice but to go the same speed. Look to replace a lot of broken parts.

quaifes are torsen. on a torsen (gear) diff, under accel, it's full lock guaranteed. There's no clutch slippage problems. Both wheels will spin or the diff will break.

 

Just for reference,

Obx/quaife are both superior to oem LSD's

 

well from what ive seen i like what i got.... my buddys got an obx lsd and for the most part it works they way it should but every once in a while hell launch and only one wheel will spin and then both will catch.... with a clutch pack its pretty much always engaged... im just saying for the money an oem will be better then a welded diff

 

For our cars yes. The obx/quaife type is superior to a welded type.

 

opens better then welded

 

if ur car is a drag car and you never drive it on the street weld that bitch but if u drive the car on the street u wont be able to turn for **** and your gonna snap axles and if you snap a axle going down the track you are going INTO the wall
