My EG with B16A made about 3 secs a lap @ Eastern Creek after the addition of a Mfactory LSD. Sooooooo much better to drive out of corners. Highly recommended for sure! Eastern Creek 1.52.25 - Wakefield 1.10.9 -
Open diff on the track is just hilarious. Can you say extreme power-understeer? Fishhook at Wakefield in the wet... LOL!
String, you couldnt be further from the truth man, my dc2 is running significantly more power than stock on a standard gearbox and i get no power understeer at the fish hook at wakefield. Sure i could take a couple of seconds off my time with an lsd which is soon to be installed. Just a helpful reminder that if you know how to drive your car there is no such thing as understeer :P
Bought a Kazz myself for my eg few mths back and at the same time my fren with an EK9 bought a wavetrac. We installed the LSD ourselves.
Wavetrac install into the box was a breeze, using oe speedo ring gear on lsd and stock FD bolts. No need shiming for the correct bearing preload in his case it was exactly the same as the oe lsd. In my case I had to shim mine 0.3mm.
Had a run in his car with wavetrac over a week ago at a autokhana tuning day, I was very surprised how aggressive the wavetrac was ie very effective on tight turns and no clunking like the Kaaz. Throttle modulation in corners doesnt take time to lock as per the normal torsen diff.
Being a torsen design there is no wear and tear in the long run of the clutch packs and no need for specialised LSD oil with friction modifiers built in.
I was expecting the wavetrac to be more mellow and some latency during throttle modulations but that wasnt the case. Knowing what I know now I would buy the wavetrac next time before the Kaaz for sure. I went for the Kaaz as my car is a trackcar so the noise is an non issue for me and I assumed the 1.5way clutch type lsd had to be more immediate than a torsen design though a much improved design.
They are relative new to the market and for those who are skeptical about the strengh of the unit, check out other non Honda cars apps; they are very popular fitments in BMW 135i/335i's where they dont come with LSD ex factory like the M3's. Likewise in Golf GTi's and their Audi S3 cousins. Those who install aftermarket LSDs into their cars in that sector seldom leave their turbo engines stock and plenty of them are putting out big numbers at the wheels.
Hi guys, just asking a noob question here. How much faster would you go with a LSD gearbox vs a non-LSD gearbox? Has anyone made a comparison yet? Example B16A with no LSD and B16A with a CTR/ITR gearbox? Worth getting an OEM LSD gearbox along with a transplant or save up and go aftermarket later on? And if aftermarket...1 way or 1.5 way? Those MFactory LSDs look tempting!
OE torsen LSD is 100X better than an open diff.
OE torsen diff can be very effective at the track provided you drive according within its limations ie keep the preload on the inside wheel the best you can ie keep throttle on during cornering best you can - on-off-on-off cost you time as oe torsen and quaife has a latency before locking as such. And stay away from hopping over ripple strips where the inside wheel gets up in the air. Huge front sway bar tends to pick the inside wheel up during hard cornering also.
I sourced an OE lsd out of a DC5 in hk for a friend in Perth in a stockish FN2, made a huge difference to the way the car felt at events.
With plate type LSD and wavetrac they are better again but not night and day difference as in the case of open vs oe lsd.
If you decide to you clutch type, 1.5 way. I was concerned about possible understeer on corner entry as the 1.5 way is meant to partially lock when coasting on my 1.5 way (Kaaz) but in fact I couldnt feel any ill effects on corner entries as some suggested it would do. I felt more like the diff has some preload on the clutch packs when coasting to prime the lsd to react faster, ready to pounce when throttle is applied.
