This morning it was a fresh 91F out, so I ran some new baselines for the STS-V.\u00a0 Just tickling the 5 sec line at 91F.<\/p>\n

Weather: 91.4F; Baro 29.12 Hg. (14.3 psi); Humidity 10%.\u00a0 Fuel: half-tank.\u00a0 Altitude: 600 feet above sea level.<\/p>\n

My Cadillac is a 2008 STS-V with a Spectre Intake.\u00a0 This is a 4,233 lb sports luxury V-Series sedan with a 4.4L supercharged & intercooled V8.<\/p>\n

Today in hot weather it ran a 0-60 time of 5.42 sec (0 feet-5,280 feet), or 4.98 sec including 1 foot of rollout as at a dragstrip, (1 foot-5280 feet).<\/p>\n

The 60′ time for this run was 2.3 sec.<\/p>\n

Previous measured times for my STS-V with me driving were 5.39<\/a> sec w\/rollout and 5.29 sec<\/a> w\/rollout, so today’s time of 4.98 sec<\/strong> w\/rollout is an improvement of 0.3 sec.\u00a0 Between the runs I have changed the tires, added the Spectre intake, and changed the MAF.\u00a0 Side by side, today’s run would have been 17 feet ahead of the previous run at 60 mph.<\/p>\n\n\n\n\n\n<\/colgroup>\n\n\n\n\n\n\n\n\n\n

Here is a view from HPTuners of the peak near 60 mph for this run showing that I am getting -3.2 degrees of advance due to the ambient and IAT2 \/ MAT temps at this point; it heads as low as -4 degrees.<\/p>\n

\"\"<\/a>

IAT Advance at -3.6 degrees<\/p><\/div>\n

I believe that because the boost is calculated from Manifold pressure and barometric pressure, that it reflects boost after the pressure drop across the Laminova intercooler tubes.\u00a0 So some pressure going in, 9.4 psi getting to the engine in this snapshot.<\/p>\n

Here was a video of the HP Tuner scan of the 0-60 run:
