New low time today — a 4.55 sec 0-60 mph with rollout, or 4.94 sec w\/o rollout.\u00a0 This was my goal for the V — to get to a solid <5 sec without rollout.\u00a0 Car had 3\/4 tank of fuel and the run not heat soaked.\u00a0\u00a0 The STS-V has the Spectre cold air intake and a Corsa axle-back exhaust system.\u00a0 I weigh 35 lbs more than the standard 160 lbs for the buff magazine journalists who get the great times for car mag tests.\u00a0\u00a0\u00a0 Local fuel is 93 octane E10.\u00a0 The backup 0-60 run was 4.74\/5.13 sec.<\/p>\n

The 60′ time was 2.2 sec, which is an improvement from my usual 2.4 sec.\u00a0 PkAccelG was 0.77G. The 1-2 shift was recorded at 0.4 seconds.<\/p>\n

Peak Hp was calculated at 6,371 RPM: [click on the image to zoom, hit back to return]<\/p>\n

Peak calculated HP at 6,371 RPM<\/p><\/div>\n

Calculated HP has steadily run less than expected on this V, but I am not clear why.\u00a0 It uses the Delivered Torque calculated by the engine at RPM to calculate theoretical HP.\u00a0 The value is a notional figure and not considered accurate for tuning, but I use it as a relative indicator.\u00a0 I am also not able to run flat out in 4th gear as on the dyno though.<\/p>\n

Same run, peak HP at 65 mph at top of 2nd gear:<\/p>\n

Top of 2nd gear at 65 mph<\/p><\/div>\n

Interesting that boost in 2nd gear was running 10.6 psi vs 8.8 psi at the top of 1st gear.\u00a0 I do not think this is a tuning issue but may have just been a transient thing.\u00a0 The boost was trending in the 9s then dips and then peaks at 10.2 psi at the 1-2 shift in the scan.<\/p>\n

Due to the low temps, the IAT Advance was actually ADDING timing instead of retarding!<\/p>\n

Here is the cold air IAT \/ IAT2 histogram for the whole test cycle:<\/p>\n

\"\"<\/a><\/p>\n

No KR anywhere on the run.\u00a0\u00a0 PE is commanding AFRs down to 10.5, so that is something to consider.\u00a0 Safe AFR for a supercharged engine probably up at 11.5 to 11.8 where the engine should make more power.<\/p>\n
