Wow, lots of stuff to digest here.
Just Mike, I have a closeup picture of carbon flash metallic and a side shot of my car in the gallery.
I got one call from a friend through Bosch and confirmation from one of the powertrain engineers that the Bosch sensors are 3.0 bar sensors.
The powertrain engineer also mentioned the production sensors are 2.7 bar sensors, not 3 bar sensors as previously reported.
JeffinDFW: it takes significant time to validate and certify a new calibration for emissions in all 50 states, or so I have been told. The 2009 model year only started a few months ago. Just look how long it took to get the kit together for the 2007 and 2008 model year.
*revised* I have more info: By law for a 50 state emission certification for any after market modification, the process can not even start, which is the letter of application for certification, until the OEM package has completed certification and is in production. The process is handled by the California Air Resources Board and takes a lot of time.
Many of us in all areas of the Kappa development team have spent time on the forum in the past, and used some of the information gleaned from the forum for problem solving since the beginning. This is not the first time I have ever come to the forum and looked at and read through posts here, it is just the first time that there has been a clear policy from General Motors regarding forum participation and I have posted information in public.
I have also attended runs with the NEO/PA group early on, been to Baker's here in Milford with Flash, and attended the 1st National Meet in blazing hot K.C. and the 3rd one in Las Vegas. My wife and I were at the first Mecca Tour, and I attended the second Mecca Tour and got to meet many other people face-to-face that I had only communicated with through other means, so that was lots of fun.
High Performance Vehicle Operations, the group that is responsible for developing the Performance Upgrade, is aware that I was going to post this information, and we discussed what I can and what I cannot share. For the most part, this is more detailed than most other tuners will give you, and honestly I cannot think of anything that is a real secret. You know what the power and torque look like for the kit, I accidentally slipped and mentioned the HHR SS, and the cost has not yet been established but I am sure that you all will be among the first to know the Performance Upgrade kit cost as soon as it is established.
Regarding performance: I do not think we have run any cars on a chassis dyno. There is a reason for this. The prediction models, given the vehicle parameters and engine torque curve, are quite accurate. Our predictions of stock vehicle performance for both the 2.4l and the 2.0l t were less than 1% off of actual vehicle performance for 1/4 mile and 0-60. The change in performance for the Performance Upgrade was very accurate as well. In fact, it is very possible to get significant variation on a chassis dyno that may not translate properly to a drag strip, so one must treat dyno information with great care. I have expressed this following thought to people I have met where we have had great discussions and seen it repeated from time to time: what really matters for true performance is when the car is driven, not what a dyno says and not what it feels like. 30 dyno hp and 80 dyno ft-lbs do not do you any good if they do not shave off several tenths of a second on the drag strip.
