The Silvia is currently running 10psi with a nice flat fuel curve thanks to some tuning with the SAFC2 and a wideband oxygen sensor/laptop. This made a huge difference to the power but I am going to fit a larger intercooler soon and see how it goes with 14psi. The car handles really well on the racetrack despite the extra weight up front.
The intercooler has been fitted and the car Dyno tuned putting out 290hp at the rear wheels. As the boost curve shows boost drops off to about 11psi at high revs but the turbo comes on boost at about 2800rpm so it is a good compromise. The initial power run peaked at 299whp running slightly less boost and with more boost I got over 300whp but I had to retard the timing a little as it was detonating. Some tuning of the mixtures gave a large increase in torque in the midrange.
