My car is mostly stock but I thought I'd make a post about my progress with the few things I've done and their purpose. - TracKey (purpose: performance) : This is pretty obvious. I have read plenty of articles about the development of the track key with numbers ranging from 200 to 400 parameters in the PCM being changed, including throttle response, torque management, intake and exhaust variable cam timing, ignition timing, among others. It also automatically sets the steering weight to heavy (adjustable with the regular key) and relaxes stability control safety nets. I feel like ABS is also less intrusive/aggressive but have never read about that so could just be in my head. The intent was to tune the engine to run like the Boss 302S race car, dialed back only for street durability requirements and emissions. - Ford Racing Torsen Diff - OEM spec (purpose: performance) : I bought my car used (with 231 miles, mind you). It's a long story but the point is, I didn
A few weeks ago, I made a post explaining mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky
