05GT Guru Posted December 10, 2008 Share Posted December 10, 2008 I do it all the time with our beater truck up north, its an manual late 70s early 80s bronco. Its also the truck i learned to drive stick with on the ice, it takes the strength of 2 arms to go from 3rd to 4th Link to comment Share on other sites More sharing options...
WhatV8 Posted December 10, 2008 Share Posted December 10, 2008 <snip> Even though you have AWD, you can only stop as quickly as a FWD drive car Only some folks have AWD, but everyone has all-wheel-brakes, so there is no advantage there. Those who forget that are afflicted with what I call "SUV Syndrome". Link to comment Share on other sites More sharing options...

Jacks GT Posted December 10, 2008 Share Posted December 10, 2008 I like this idea, ima quick shifter, i can handle the car, i think it could be intresting....now all i have to do is wait for snow in costa rica or florida.......hmmm Link to comment Share on other sites More sharing options...

Impulse Posted December 10, 2008 Share Posted December 10, 2008 Glad you are enjoying it, but there's enough stories on here, and other Subaru boards with the same thoughts, only to be shattered by hitting a kerb, or a post, or something else. Even though you have AWD, you can only stop as quickly as a FWD drive car dosent our center and rear diff work in reverse too? so, in theory.. all wheel engine braking? it snowed recently, so i tried bringing the car up to speed in 1st (~20 mph), clutched out, waited for the revs to drop, then clutched back in, basically engine braking. obviously the rears started sliding first, but it took alot of effort (had to put alot of load on the clutch). it also SEEMED like my front right wheel started sliding at the same time because the car was starting to rotate to the right, at that point i clutched out again and brought the car to a stop using the regular brakes. might not be as effective as brake force distribution, but it would mean that our AWD (atleast the MT) system is more stable when coasting, engine braking Link to comment Share on other sites More sharing options...

When I had my Baja T, i got a little stuck trying to back up with one of the front wheels with almsot no load on it and it just spun. I spoke with the dealier and they said that this is normal. Now if they have changed that, my comment is null and void. But I have a feeling that they haven't. Reverse is FWD only.

ehsnils Posted December 10, 2008 Share Posted December 10, 2008 That's the 4EAT, the MT has a 50/50 differential with a viscous brake, the 5EAT has yet another technique and the Impreza STi is having a fourth system. Earlier versions with manual 4WD didn't have a center diff so there you always had a full lock-up when you engaged the 4WD. Link to comment Share on other sites More sharing options...
fishbone Posted December 10, 2008 Share Posted December 10, 2008 If you engine brake, awd does have the advantage of 4 wheels holding the rest of the car vs two front wheels. Link to comment Share on other sites More sharing options...
05GT Guru Posted December 10, 2008 Share Posted December 10, 2008 5EAT has the same theory as the MT except its a 45/55 split correct? Link to comment Share on other sites More sharing options...
fishbone Posted December 10, 2008 Share Posted December 10, 2008 Technically the 5EAT's torque split is 44.3% front and 55.7% rear The 5EAT awd is different from the MT in the sense that the transmission is a lot more "in touch" with the awd drivetrain than on a manual. The center differential iirc also operates differently. In a sense it is a different awd drivetrain with similar functionality. Link to comment Share on other sites More sharing options...
fishbone Posted December 10, 2008 Share Posted December 10, 2008 Although it refers to the 4EAT, this site has great info on the different awd designs: http://www.subaruspecialists.com/mainframe/frameAllWheel.html Manual: In vehicles with the 5-speed manual transmission, the All-Wheel Drive uses a viscous coupling in a center differential inside the transaxle case. It contains a series of opposing discs attached to the front and rear output shafts, surrounded by a silicone fluid. In normal operation, power is distributed equally between the front and rear wheels (50/50 power split). Loss of traction at either the front or rear wheels causes a rotational difference between the front and rear discs in the viscous unit, which then shears the silicone fluid. Automatic: Subaru vehicles equipped with the 4-speed Electronic Automatic Transmission (4EAT) feature a different type of All-Wheel Drive than with the 5-speed manual transmission. Instead of a viscous coupling center differential, an automatic transmission-equipped Subaru features an electronically managed continuously variable multi-plate transfer clutch located in the transaxle's tailshaft. Power transfer is governed by slippage in the clutch plates, which use a special friction material that easily handles the loads generated during power transfer. I don't think, for one, that the manual has a speed sensor harness. The AT depends on this harness which tells it what speed the front and rear wheels are going and what they are doing to properly determine shifting and shifting characteristics. Should any of these sensors fail, the AWD falls back on the 4 independent ABS sensors to maintain normal operating conditions. I found that out the hard and expensive way when my rear speed sensor failed. The 5EAT is tail happy in snow when pushed. When switched to manual mode, I assure you my 5EAT is at least as fun, if not more fun than a manual. I've driven both, I like mine better still, even getting out when stuck. Upshift to 2nd and apply the brake gently. Off you go. 'tis the reason of the high-stall torque converted (3100-3400rpm). No chance to apply too much torque in those conditions.

aigochamaloh Posted December 11, 2008 Share Posted December 11, 2008 Engine compression is far more useful than rubber trying to grip a slick surface to shed speed. What? This statement makes no sense. Whether you engine brake or not, rubber is what contacts the road and provides the normal and frictional force for you to stop. What are you trying to say here?

snow05gtRI Posted December 11, 2008 Share Posted December 11, 2008 i feel like with engine braking you're using axle to tranny friction to slow the car down instead of wheel to road. i think the stress points where the force is are different. because if your tire is going to slip, your brake can lock up the wheel. the engine braking wont lock your wheels up.

That's why I'm off to bed, I'm beat... long day. I think what I was getting at is by utilizing engine braking you can avoid needing to hit the brakes.
