- All O2s are original, got new ones in a box ready to go in when my V1s arrive, but potentially left some power on the table because of this
- Running Shell V-Power 91 octane
285 max WHP, 234 max WTQ
As expected, the car was running rich, but made more power than I was expecting.
PCS tune:
294 max WHP, 245 max WTQ (different runs)
All runs were done back to back, so you can see the car progressively get heat soaked. I flashed the car while it was on the dyno so it had a good ten minutes to cool down then for the PCS tune, but looking at the last PCS run, I think it could have made a little bit more power if we had let it cool down some more. Torque was up significantly from the first PCS run and then it just fell off.
Not the most insane numbers, but happy to have satisfied my curiosity. I'm excited to see what the car will do with the Supersprint stuff and Paul's dyno tune. Also attached the individual runs in case anyone is curious.
