Had a dyno run on my bone stock 06 STS-V today. She put down 365 RWHP but that was after running hard on the track at Pocono Raceway. The oil temp was around 230 degrees on the first run and kept climbing with the other 2 pulls. Overall, I was pretty happy - what have you guys seen in stock trim? I was also impressed with the capabilities on the track for a 4k lb land yacht. Can't wait for V-Day II. Hope to meet some of you guys there.
That is dead on consistant with all the other stock STS-V's we have baselined and tested. You made mention of the heat. We have some items for your application that will reduce the amount of heatsoak and let you have a little bit more fun before the thing starts heating up too much (i.e. Larger Intercooler Reservoir, 1600CFM push fan, more efficient heat exchanger).
