options for differentials

[Cudarich]

Hello all, I am new here and searched the forum for differential options and was just curious in any additional ideas. My team does not have the resources to build our own differential and we are looking for built chain drive differential options. I have already looked into;
Taggart Performance
Taylor race
and I am just looking for any other options.

Thank you very much for your contributions.

Here's a UK-based option. If you look around the web, there's all kinds of info from them if you want to DIY part(s) of it:

Here's an LSD with reverse:

Don't know if this is LSD, but it's $3500:

If you have the resources to make some sort of mounts, Quaife (UK) has this:

Of course, there's the Torsen University Special, if you have the resources to package it:

I'm sure that I have overlooked several options, but these should get you started in your search.....

If you have the resourse to build your own end bells we have the 0200059.

This runs $1.180

Or the complete diff 020059C . it comes with a sprocket flang and with or without a rotor flange.
for $2.210.00

The Civic based diff

This one is $995.00

If these links do not work and you would like some pictures or some drawings please shoot me an e-mail.

If you're able to, go for the Taylor stuff. Even if you don't get one of their diffs they now make integrated stubs/c.v. housings suited specially to the university special TORSEN which cut down greatly on cost and complexity for us.

hey

the torsen differetnial is popular too, check it out at www.torsen.com (http://www.torsen.com)

Personally I think the Taylor stuff is far over priced and not worth the money. Sure it works great, but goodluck in the design competition when you have to explain that you bought your entire Drivetrain sub-assembly and let somebody else do the engineering for you. I think it's much more cost effective to buy a cheaper subassembly and customize it to the applications needed by your team, as say in some of the ATV applications. Usually the components won't fit right out of the box and new axles and differential modifications will be needed. But in doing so, your team will be far more knowledgable about the components you're using and will also be responsible for their design features. Taylor's not a bad way to go, but why spend four times the money and sell yourself short in design when you can use something else that's just as easy to put together?

The original poster said that their team didn't have the resources to build their own. Some teams apparently don't have access to full CNC-equipped machine shops, so nothing is "just as easy" as dropping the coin on a known assembly for them.

Given a choice of scoring design points on an incomplete chassis stuck at home or buying someone's completed assembly and losing some points in one area while gaining the experience from being at the competition, I can see their logic for buying an assembled unit.

Scotty should look into setting up a rental program, just like some of the major race car engine builders do... http://fsae.com/groupee_common/emoticons/icon_smile.gif

Thanks for the support...
It is very much apprieciated.

I'm not hating on Taylor, I'm sure they make a good product, but some people just can't afford it. I would have liked to go with Taylor, I even worked with Scotty on getting everything together, but bottom line, we couldn't afford it. We're using a diff that cost $130 dollars, the Qauife Taylor diff was $1000. As far as teams not being able to have the resources to go with an option such as ours, the only machine we're using to modify the entire drivetrain is a lathe. Yes, a single lathe for everything. If an engineering school doesn't have a single lathe on campus, than I'm pretty sure it's not an engineering school...

Hey Conor, The judges aren't going to dock you points in the design event just because your team didn't have the resources to build a diff from scratch. As is reiterated every year, it is the "Design and KNOWLEDGE Event." We have used Taylor products since 2004 and since have not had a single drivetrain related failure in competition. The point is, if you know how the parts were engineered, how they work, and how you WOULD (not did) manufacture them, then you will get full marks in design competition. End of story.

EDIT: And why you used them. and how efficient blah blah blah. Know your shit in other words. Sorry, had to get that in before someone chimed in with some BS on that.
