Re: Accepted to grad school! Summer plans

JDM Impreza WRX STi & STi RA MY01-02
TY856WB1CA
1- 3.636
2- 2.375
3- 1.761
4- 1.346
5- 1.062
6- 0.842
rev- 3.545
Drive ratio 1.000
Final drive- 3.900
Center diff type- Viscous (4kgf)
Front diff type- A.P. Suretrac
Notes- RA STi w/ 17 in. wheel

Its not a dedicated 50/50 split. I spent a lot of time researching the trans when I lived in England. I got to hang out with some really knowledgeable guys including Richard Bulmer of Tracktive Solutions UK and my fav guys at the now defunct WRC Technologies. It was explained to me that typically the Viscous center diff in that trans relies on slippage (heat) to thicken the fluid to vary TQ split. This effectively makes the trans rear biased. The amount is one of much debate but its considered close to 35/65.
