The tracker is 4x4 and the rims fits perfect. I tried some different but only these works on 4x4.
I haven't dynoed. I was on a dyno to tune it but they couldn't fit it on it. But it runs strong and safe. It used to downshift on a highway to keep the speed with cruise control activated but not anymore. Runs in 4th all the time now. I suppose the factory 127HP are now on the wheels. At least that was my calculations designing the system.
It has wide band O2 sensor, EGT sensor, Knock sensor with J&S Safeguard knock system. The engine safety was my first concern building the SC. I'm monitoring the engine under boost and it runs 12.5 AFR under 7 psi boost. And J&S doesn't retards the timing, just no need for that, no detonation.
Anyway I'm selling the tracker now and don't want to put any more money in it. I just got Mazda RX-8.
