Ask Tadge Poll: Ending 21 February, 2016
Vote for which of these 5 you'd like to have Tadge answer. The winner will tentatively be submitted Sunday, 21 February. Please note that Tadge will be taking a business trip and vacation sometime near the end of February, so I might need to delay sending him the question until he returns. If that's the case, I'll just hold on to whichever question wins, and send it when I can.
The questions are posted in the replies below, with links to their respective threads. |
Aero Properties of the C7 Models
Original question is here.
descartesfool asked: In order to better understand the performance differences and goals of the C7 models, could you detail the values for the lift and drag coefficients and frontal areas for the base, Z51 and various Z06 versions and front to rear downforce ratios and total downforce at speeds, Lift/Drag ratios, and why they were chosen? |
Can "Performance Shift Active" Explained
Original question is here.
AllFlash asked: Under certain conditions, accelerating ones Corvette will trigger 'Performance Shift Active' on Corvettes and a number of changes are observed, least of which is a delayed changing of gears in the A8 while acceleration or deceleration is present. Can you explain exactly what changes the car experiences, whether it be engine, transmission or suspension while 'Performance Shift Activated'...is active? |
LT1 Differences Across Various GM Models
Original question is here.
Kracka asked: I am curious about simple, but possibly interesting question. The LT1 is now used in multiple models, the Corvette and Camaro. Are the actual engines identical in design and specs as they're built before getting prepared for installation (i.e. before manifolds, etc. are bolted on)? If they do differ, what differentiates the Corvette-specific LT1 from the others? While we are on the topic of the LT1, what was the reasoning behind the decision to bring back (or recycle, depending on how you want to look at it) the LT1 and LT4 engine designations. Thank you for your time and consideration! |
Different Oil Needed for Street vs Track
Original question is here.
descartesfool asked: What is the effect of changing from Dexos compliant 5W30 to Mobil1 15W50 for the track and back for road use? Some cars which are used on track a lot such as Porsches and GT-Rs recommend Mobil 1 0W40 for all uses, with no changes required when driving on track. Would this oil be fine for track and street use in the C7? What are the negative effects of leaving the 15W50 after track days and driving on the road, and at what temperatures is it an issue, hot or cold? |
C7 A8 Transmission/Torque Convertor
Original question is here.
Maxie2U asked: 1) A8 Transmission: a) what changes and/or redesigns were made to the newly released A8 transmission (new part#24274892)? b) what is the date Bowling Green began to use the new transmission in production? 2) Torque Converter: why was it necessary to release a redesigned torque converter this year (as referenced in document id: 4373638)? How does this affect owners that have the old torque converters? |
OMG we absolutely need the oil question answered. Track prep on this car is not even feasible (or affordable for most of us) for a daily driver. If it doesn't make the cut this week, remind me to expand it to include all track prep (cooling rings, alignment, what else am I missing???).

He ought to be answering this one...

If already answered, I apologize. The % of times this appears to show up, and the Ford Pinto-like potential for fatal fires in home or possibly on the road, is disturbing to say the least.... |
