Bruce Nunnally Posted April 16, 2016 Author Report Share Posted April 16, 2016 The Challenge was in 2009. Cooper was a student at NYIT at the time. Prior to the challenge he attended Skip Barber Racing Academy. Michael posted: "I did the skip barber 3 day course last summer and then the 2 day course at the end of the summer/fall. Other than that Ive ran 2 skip barber races and tracked my previous z06 twice, Had never been on the track in the M3."See http://www.m3post.com/forums/showpost.php?p=6127001&postcount=165 Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...

Bruce Nunnally Posted April 17, 2016 Author Report Share Posted April 17, 2016 Johnny O’Connell has been stripped of his victory in Sunday’s Pirelli World Challenge race on the streets of Long Beach due to a technical infringement determined post-race. O’Connell’s Cadillac ATS-V.R was found to have exceeded its allowed boost levels in the race, which has promoted Alvaro Parente to the race winner. http://sportscar365.com/gt/world-challenge/oconnell-penalized-for-overboost-parente-inherits-win/ Cooper charged through the grid but then went out after rising to 4th Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted April 17, 2016 Author Report Share Posted April 17, 2016 The boost tables and allowed boost per GT3 rules are complicated. This 2015 rule set shows the pressure BAR to PSI conversion limits: http://www.world-challenge.com/images/bulletins/Appendix-A-GT-Ver-92.pdf with ATS-VR limits in 2015 as follows: and this 2016 update impacts allowed boost: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=7&ved=0ahUKEwjk4q2E5ZbMAhWMSCYKHRVMCk4QFghDMAY&url=http%3A%2F%2Fwww.fia.com%2Ffile%2F38840%2Fdownload%3Ftoken%3DaBcuWQ8-&usg=AFQjCNEfn7Y9nKF_y4ZVHFVZyw4zR8d8sA&sig2=QEPujj-EjgkIhapNMLRE0w&cad=rja I think together these say the ATS-VR is allowed: 1.78 at 8000 or just over 26 PSI of boost in 2015, raised to 1.81 at 8000 rpm in 2016, or 27 PSI, with varying limits at each RPM. The teams are responsible for adjusting to local conditions. Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted April 17, 2016 Author Report Share Posted April 17, 2016 O’Connell offered this up after the race, about the penalty: “In post-race tech they found we had a few boost spikes that were not to their liking,” he said. “From what I understand these were when we were in traction control situations, so not a speed advantage at all. But rules are rules. A second place finish does not take away from the accomplishment of Cadillac Racing today. I am proud of the team.” Read more: http://motorsports.nbcsports.com/2016/04/17/redemption-for-oconnell-in-pwcs-return-to-long-beach/ Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
