SR20VE-T/RWD

655hp@20psi 8500 redline, some ignition misfire above 6k. you can see on the next pull @24psi, it spun the tires on the dyno and stopped reading, but was on an average of 112hp more across the board.

New high for me. 157 whp and 128 torque

93 octane - cams, header, intake, exhaust, JWT ECU, Apexi SAFC II

There is still plenty of room for improvement:
- way too rich after 6000 rpm
- some ugly dips at 2000 rpm
- safety timing for A95 fuel (something like US 89 or maybe worse..)

Next dyno day is planned for later this summer. Hopefully it will bring better results for me, although current are not that bad as well.
