Bruce Nunnally Posted April 6, 2012 Report Share Posted April 6, 2012 My Monday dyno has been pulled up to Saturday, so I ran out to set a new baseline today. New low time today — a 4.55 sec 0-60 mph with rollout, or 4.94 sec w/o rollout. This was my goal for the V — to get to a solid <5 sec without rollout. Car had 3/4 tank of fuel and the run not heat soaked. The STS-V has the Spectre cold air intake and a Corsa axle-back exhaust system. I weigh 35 lbs more than the standard 160 lbs for the buff magazine journalists who get the great times for car mag tests. Local fuel is 93 octane E10. The backup 0-60 run was 4.74/5.13 sec. The 60′ time was 2.2 sec, which is an improvement from my usual 2.4 sec. PkAccelG was 0.77G. The 1-2 shift was recorded at 0.4 seconds.

Bruce Nunnally Posted April 7, 2012 Author Report Share Posted April 7, 2012 Had fun having lunch with my Motorama friends at Uncle Julio's to celebrate Donna McClellan of the Arlington plant's birthday, then headed up to True Street Motorsports. Good info on the dyno, and putting down a solid 394 whp, or 493-505 crank hp (20-22% trans losses for 6L80 transmission. Article on the way.

Bruce Nunnally Posted April 8, 2012 Author Report Share Posted April 8, 2012 Here is the dyno graph: Adding the Corsa exhaust to the Spectre CAI freed up another 19 whp and 21 lb ft of torque. I wish there was a way to stabilize the intercooler heat load on the dyno. So close to 400 whp but needs another adder.

Bruce Nunnally Posted April 8, 2012 Author Report Share Posted April 8, 2012 Jim I think you'll approve of the changes. It moves pretty well now. Now if I can find an intercooler cooling solution that works well for this application.

Bruce Nunnally Posted April 9, 2012 Author Report Share Posted April 9, 2012 Nice work Bruce This was the result I was hoping but it was good to document how these parts work together. Conventional wisdom among STS-V owners online is that the Corsa's don't add much, but clearly they do quite well along with the CAI.
