Audi A4 2.8L Quattro NA - ITS car?

:023: Cool you guys hit the topic that was of concern to me which is the adjustable diffs. I was interested in Ben's insistance that All AWD cars are better in all conditions. I know that my 240hp A4TQ which I have driven hard plows like a pig due to the inability to move the torque split rearward. My buddy's 425hp STi however has the ability to adjust the center diff which has an electronically adjustable clutch type LSD in it. 65r/35f

That little gizmo buy itself makes a HUGE difference over his other std WRX which has a fixed 50/50 split. So since we don't allow adjustable sway bars, shocks and other things from the cockpit I'd like to see only fixed diff AWD cars allowed and also would like to see unmodified gears (all drivetrain gears) at first.

Being inclusive doesn't mean we have to go overboard. :D In fact it would be doing to AWD guys a favor if we slowly ALLOWED more mods overtime than if we gave them something and then took it away later $$$$. The point is to at first just let them play. And when it rains...so be it!

hmmm 4wd VWs .....

I'd prefer not to see these in IT just yet...

Bill - you got me pegged! Cat is out of the bag - one of those Haltex units is exactly what I had in mind for tuning the car for optimal performance. It would be a blast testing with that - I bet you could make the handling characteristics very different and as a driver, know just how to dial in the car depending on race conditions.

I was concerned about how the rules would address a device like the Haldex which is another reason why I sold my car. Figured I'd see how things sort out.

An AWD VW - now that's something to noodle on :D
 
Just for giggles, lets come up with a list of cars that could be included. Has to be 5 yrs old, and it's IT, so AWD Audi A8s or RS4s aren't a good idea....

But, lets look back as many years as there are AWD cars still available and desirable, and forward a few years.

Lets list curb weight, yrs covered, stock hp, as well as make and model.
 
1998-2001 Subaru Impreza 2.5 RS (coupe & sedan)

2.5L horizontally opposed (boxer) 4 cylinder engine
165 HP @ 5,600 rpm
166 TQ @ 4,000 rpm
multi-port FI
distributorless ignition

99.2" wheelbase
2,825 lb curb weight (not sure if this is the coupe or sedan - probably coupe)
16" wheels
10.7" vented front rotors dual piston floating caliper
10.5" solid rear rotors single piston floating caliper

front suspension is McPherson
rear suspension trying to find a picture - there are a few links involved

There weren't many 1998's made in the US (1,695) and there were year to year changes in cams, including single or dual. If a clear cut was wanted maybe just the 2000 & 2001 as they had the same set up throughout production and have the widest available donor population - our allow update/backdate of the whole engine as it came in any given year.

I forget which diffs are open and which are LS (think rear is definitely open though) - none have adjustable torque distribution or adjustable locking.

And AWD has higher drivetrain loss than front or rear WD.
