Re: Quaife differential? (R_Rated)

Had one in a 1998 Porsche Turbo, they work well with early Porsches that have a lot of hp but have no idea about any other cars

Re: Quaife differential? (R_Rated)

How would this affect the R? We already can't spin the tires in straight line acceleration which causes the dreaded bog, wouldn't this just perpetuate that issue?

Most differentials help to get the power to the ground more efficialtly. My tires do/can spin through 3rd in a straight line. On a stock R a differential is pretty pointless as there are mods that will make so much more of a difference on a stock R.<p>The R32 is haldex AWD and when you thave the "AWD tune" the car drives better... even though it is alraedy awd and "the tires don't slip".<p>I am just wnadering is any R owners ahve done this yet so they can give me a heads up on any suprises they may have found.

Re: (R_Rated)

My AWD Talon had a limited-slip diff in the rear, although it was a different type (viscous, not gleason/torson). The car had a noticiable RWD-feel in the snow, but like R, wheel spin in the dry was not an issue.

Re: Quaife differential? (JOSBRO)

This is what I thought too. However, I have very little education/experience with the technical end of AWD, so I was hoping that someone with a little more knowledge would chime in and give the pros and cons of a system like this vs. the regular old Haldex system we have.

Re: Quaife differential? (R_Rated)

Have one in a modded 2001 GTI 1.8T running 411whp. Can spin the tires up to third gear, keeps the car in a straight line. Nuff said. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: Quaife differential? (ReVolvR)

I detect a little confususion here. The Quaife differential is a Gleanson/Torson type of differential, as opposed to the common clutch-type or the less-common viscous type. Each type has different torque transfer characteristics, which can be discussed if we really want to get that geeky. <p>In an AWD car, it can be used in one, two, or all of the following locations...<p>Front axle<br>Rear axle<br>Between front and rear <p>In the R, the front/rear torque split is handled not by a "differential" in the strict sense of the word, but by an electronically-controlled clutch pack ("Haldex"). Side-to-side torque transfer (both front and rear) is accomplished by electronically applying the brake on the spinning wheel ("TRACS").<p>You could theoretically use a mechanical differential (e.g., Quaife) to replace Haldex and/or TRACS. I don't think the cost-vs-benefit equation would be favorable though.<p>How the heck do you pronounce "Quaife" anyway? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> <p>

so no one has done this on an R? or experimented with this?<p>I am not wanting to know if people think this will or wil not work in theory. I appreciate your thoughts but U am really just looking to see if I can learn from experience and hopefully not mistakes.
