Rent A Diff, Any interest?

Bass Crazy · 22-06-2005, 08:14 AM

Hey guys.

I was just wondering if any of you guys would be interested in a 'Rent a Diff' service.

Basically, you would be able to rent an e-series diff, with a shorter ratio (3.7, 3.9, 4.11) install it into your car for a few runs down the 1/4, or to see if your car actually likes that particular ratio, before spending the big bucks on converting your own.

Details are rough at the moment, but the basics are.

The diffs would most likely be mini spooled.
There will obviously be a bond on the diff for those who decide not to return the diff, or if the diff is gutter bashed/ damaged in an accident.
The bond would not be lost if the internals of the diff are damaged from clutch dumping or burnouts, after all, that probably the whole point of trying the thing out.

Anyhow, let me know your thoughts, and if interested, what you think a fair per week rental price would be.

Thanks
Simon

Simon,

Great idea.

What costs are involved? I'm assuming you supply gears in housing and then use original axles and brakes?

Bass Crazy · 22-06-2005, 08:51 AM

I would most likely supplythe complete diif assembly, including brakes.
So all that all you had to do was bolt it up, and attatch the brake line, handbrake and tailshaft.

Still in the process of calculating costs.

EA2BA · 22-06-2005, 09:01 AM

I have swapped diffs before, and keeping existing calipers and brake discs makes the swap so much quicker easier, and no bleeding of brakes, and also some people make have after market brake packages they prefer to run with.

galapogos01 · 22-06-2005, 10:26 AM

Supplying brakes could lead to safety issues etc. better to supply w/o brakes IMO. plus you save on having to supply brake pads to people.

Also, cant the same housing be used between different e-series models if the user is just bolting on their own brakes?

Great idea I reckon, I would have tried it myself for sure.

Sounds like a good idea... I agree with not supplying brakes. It's easier to use your own anyway. I don't know what a fair price would be... maybe $50 for a week? I guess it depends what your cost is to put them together... you would want to at least make your money back.

If the appropiate trailing arms were provided then I cant see a reason why the same diff cant go between e-series, and only require a possible yoke change to get it to fit.

The yoke change can be a bit of a issue as it needs to be preloaded otherwise the pinion bearing will chew its self out.
You might have to take that into consideration as well.

Great idea I might use it myself.

Just run EB==>flange diff, and supply and Eb tail shaft with the diff, that will take care of any problems.

LUXO_8 · 22-06-2005, 06:46 PM

sounds like a great idea simon..

SWOOP · 22-06-2005, 07:02 PM

very interested

would like to try spool/4.11's in an EA 3 speed

niko · 22-06-2005, 07:07 PM

will rev ridiculously. 3speed revs at 2400rpm odd at 100k's with a 277 lol

SWOOP · 22-06-2005, 07:18 PM

thanks for your input

but dont care as long as it dont hit 6000rpm over 400m in 3rd

parawolf · 22-06-2005, 07:26 PM

i'd be interested for club race meets, as some tracks are suited to 'high speed' straights kinda like phillip island, and some like winton a 3.9 or 4.11 would be good. Sandown a 3.7 would be good.

I'd be very interested in weekend/weekend (by the day) rentals.

T_Terror · 22-06-2005, 09:08 PM

me also interested. those diff casings aint exactly exensive, neither are minispools or skyline gears.
why not just have two diffs sitting with both styles of yokes.

mcflux · 22-06-2005, 09:21 PM

Sounds great! Keep us updated with your plans mate

sphell · 22-06-2005, 09:31 PM

HAHAHAHA did u come up with this idea after I rang u the other nite lol! All that talk of diffs has made u go crazy :P I'd be puttin a big sticker on each diff, NO WARRANTY EXPRESSED OR IMPLIED. U BLOW IT, U BOUGHT IT.

Imagine the caning they're gonna get!

PS: i'll take a 4.11 locker;)

Bass Crazy · 23-06-2005, 08:19 AM

LOL.. well sort of Doug. Its actually been on the cards for a year or two, just haven’t had the time, but yeah, you got the ball rolling again.

Well judging by what you guys have said it seems like it may be worth a shot. Some good points about the brakes have been raised, and most likely I’ll be supplying them with no brakes.

As a personal preference, I use the EB/ED flange type yoke. Tail shafts are cheap these days anyhow.

However, if I supply a tail shaft, that would place further safety issues on my behalf, so im a bit reluctant to do that.

Has anyone got the control arm size differences handy? (EA-EB lower arm difference etc.)

Thanks
Simon

Gunns · 23-06-2005, 08:30 AM

Simon,
You can make up spacers to pack out the EA arms so they fit up to a EB/D diff, thats what I have done on mine. I'll get the size of the spacers for you.

EA2BA · 23-06-2005, 08:38 AM

Well just make it the are EB only flange, get your own tailshaft, not your problem at all then, sounds fair to me.

Bass Crazy · 26-06-2005, 08:02 PM

Hey guys,
Well I sorted a few things out over the weekend. I'll obviously start off small, and depending on how things go, make more diffs available.

The diffs are available for anyone here who is not running a transbrake or anything above 200rwkw.

How does this sound?
Rental charge $50 per week (7 days) + a $400 bond.
Locked diff supplied without any brake components.

Anyone interested in trying one out this week?

Thanks
Simon

parawolf · 26-06-2005, 09:38 PM

torque is more important that power...

parawolf · 26-06-2005, 09:46 PM

oh what about speedo gear cables or wathever?

LUXO_8 · 26-06-2005, 09:57 PM

speedo gear is in the transmision

460cixy · 28-06-2005, 02:01 AM

well maybe suply an asortment of spedo gears for diffrant ratios

FPVWEPN · 28-06-2005, 02:33 AM

locked???????????

460cixy · 28-06-2005, 03:06 AM

welded solid ;)

ClassicAU · 28-06-2005, 11:27 AM

this sounds like a great idea. i am deffinatly interested. i wouldnt mind putting one in for the E-Series vs R31 meet in august. the only problem is, i would not have a clue, or the space, to be able to install one myself. do you have the means to install and unistall these? i guess there would be an extra charge on labour as well?
oh, and also, does mine being a wagon make any difference?

Bass Crazy · 08-07-2005, 11:31 AM

I have a 3.9 diff sitting in the garage gathering dust if anyone is intrested

yeah suspension mounting bits are completely different. you won't fit a sedan diff in the wagon.. well not without a fair bit of modification (welding different mounts on it)
