Are these worthwhile in a basher?

I heard for track, to even have a chance at winning you need a one way in the front

And how much does it improve handling over geared diff with grease for LSD action?

GYNAIKAS

It depends...I prefer one way diff at tracks with wiide corners. For tight corners I prefer blocked front diff to prevent oversteer.

Spetz

I thought the one way prevents oversteer?
ie, has good turn in as the wheels roll freely into a corner, and doesn't oversteer as the front locks on acceleration?

I expected this to be better at tight tracks (minus the no braking thing)

GYNAIKAS

Blocked diff prevents oversteer by producing some understeer!

Spetz

I know... it would understeer exiting the corner + it wouldn't turn in very well though

I remember I had a 1.5 way LSD on my 1:1 car, so on power it was fully locked
Was a ***** to drive at times

I use locked front end because i like the extra braking. i used to run a front way but ever since i switched to locked front end my lap times went down a considreble amount, but it all depends on track conditions and the size of the track, i drive on a track that is fast yet, has lots of tight corners in the infield so the extra braking effect from the locked front end makes a world diffrence

Spetz

So is it a good idea to completely lock the front diff??

slideyourride90

I would tell you yes over a one way diff becuase your car woukd brake better over all but be fore you lock your front end completely try some realy thick silcone oil to see if you like the way it handles.

Where and when are races held in Miami?

Spetz

Well I will end up putting something like 100K grease in the front

I am thinking what to do in the rear. Leave it open? Or put grease too?

GYNAIKAS

In fact it's not grease but silicon oil. use 10k at the rear just for lubrication and only.

homestead miami speedway is were im usaully at its my favorite track, but i also go out to coral springs rc way which is on ramblewood dr. and university its a nice track to but i like the homestead track the most its bigger and usualy people with electric cars go to the one on univertsity. you can usauly catch me at either or every saturday. pm me if you want links and #'s [8D]

GYNAIKAS, what does Blocked diff mean?

GYNAIKAS

Well I mean practicly no diff! Either you block the front differential so that the wheels don't move separately or you use a "one-piece" axel. I apologise for my terrible english bro!

Car-Tune

How do you block it?

GYNAIKAS

Fill it with the thickest silicon oil available.

wouldnt it slow it down?

Osirisf16

When you turning, but not so much. Is straights you will have no issues about decreased speed. In corners, you want to slow down anyway so... I repeat, the desceleration will be minimal for you

Car-Tune

is the one way diff from hpi better then doin that?

slideyourride90

no not really because the one way only locks "one way" and has a free diff affect when your on the brakes or deccelrating, thus only you'll only have rear brakes but locking the front youll have a locked affect both ways

Car-Tune

So, what is it you do.....fill the front diff with that stuff?

Spetz

You fill the front and/or rear diffs with different weights to get different LSD action
So, if you want the front tighter, you put a heavier grease into it
If you want an open diff (ie, free diff) then you just grease it a tiny bit for anti wear & tear

Osirisf16

Not grease, but oil

GYNAIKAS

I hope you'll understand what I'm trying to say (due to my bad english) because it's very important! Don't fill the differential case that hosts the final gears and sits on the chasis! When we say fill the differential we mean the small case wich is attatched to big final gear and contains the differential gear mechanism (small gears that mesh together vetrically).
