Default Sti version 4.11 box, vs Version 2 RA 3.9

roarf.

so the box ive been running for the last 2 years has been a sti version 1
4.11 box code is: TY752VB3CA

ratios:

1: 3.454
2: 2.062
3: 1.448
4: 1.008
5: 0.825

Final drive: 4.111

simple stupid setup -

EJ25 dohc NA motor, redline is puny 6K.

4.11 box is awesome, its gota be the more fun street box imo, 1-5 are properly spaced out - 6K shift will land u at 4K. all 5 gears are useful, compared to the USDM 6box i drove with 1-4 really short and 5/6 useless, i much prefer the 4.11 box.

the Sti-RA box (DCCD) that went in my car yesterday:
STi-RA version 2 v-limited gearbox, code: TY752vb4ca
ratios:
1: 3.454
2: 2.333
3: 1.750
4:1.354
5: 0.972

final drive: 3.900

http://www.catherineandken.co.uk/sti/wrx.html


after driving both, the RA with 3.9 is INSANE.

3rd gear at 6,000 RPM (my pos redline) is 60mph. 4th gear is normal crusing, i can accellerate around town in 5th gear.

its nuts.

dccd dum dum (brainless - still in my front clip) is fun. its defaulting to id guess 65% rear, 35% front. really fun. i like it more i think

The RA tranny is known for the crazy acceleration compared to the normal STi tranny. I just wanted something stronger and still be able to cruise in 5th at freeway speed, and 4th for something lower. DCCD works nicely without the brain under non-adverse environment

"fwd" refers to fake FWD. you can definately convert the AWD trans to FWD if you wish, theres a buncha ways to do it

i was running the 4.11 box in AWD mode, if you are interested in buying one mine is for sale-

my 3.9 is shorter than the 4.44's. i have the shortest gears subaru ever had in a gearbox. i think it would top out at 100 @8200rpm in 5th with a 4.44 final drive :P

That seems to be the case with the DCCD system. On default it's set like that via planetary gears in the center diff. The DCCD system like works the limited slip effect, so without it, there's narely any limited slip affect at all. It's like having the cusco tarac center diff.

with a 4.44 on your gearset it would be physically impossible to go over 128 mph (5th gear, 8000 rpm). In reality, it would be lower than this. Stock fat piggo (USDM wrx) gearset/diff combo can achieve a theoretical top speed of around 185 mph, but obviously the car isn't capable of anything close to this (drag, etc.).
