As you all know the engineer Q&A session was September 19th. I managed to squeeze in many questions and found it very helpful. It seems that were many questions or myths out there answered... I managed to copy all the Q&A into a Word doc to read and here are some comments and answers I found interesting.
Keep in mind I am just abbreviating their comments and answers. I am simply the messenger here.
LETS BEGIN -
GTS Blue, Snakeskin Green and Venom Red are all in the first run of cars.
Brochures will be out soon...
Doesnt sound like there is going to be a ACR or special version.
They eluded to the fact that Mopar will be producing some sort of body kit for the Viper.
Apparantly the engineers were just as surprised as us to see the Z06 kept pace with the new Viper in some of the mags. Quote, "That comparison turned out a little different when we ran the two cars! Wait until you see some real world match-ups...."
Apprantely 3.07 were installed to maximize fuel efficiency. They do elude to the fact that the car is geared too tall.
2008 there will be a noticable reduction in heat in the cabin. The 08 hood vents were moved to help cure the heat problem.
The stock plugs are decent but you can find a better upgrade but be sure to get the proper heat range. Stock wires are decent.
They point out that ALL vehicles have wheel hop and if it is excessive, check your suspension.
Weather below freezing could pose a problem for cars with after market lower thermostats.
The Viper did set a record for C&D at VIR and beat the Z06 by more than a second with C&D driving. Fall testing will be even faster.
2008 oil pump flows 20% more that the 03-06.
Engineers feel average driveline loss on dyno is 12-15%.
Chassis dyno noise can be interpreted as knock by the ECU and it will pull out spark and add fuel so don't always believe what you see there on the dyno. Could make tuning more difficult.
Engineer Quote, "If I were doing alot of "street/light competition" i"d use a 3.55 or 3.73. Remember nvh and fuel consumption will tank!"
Inside diameter of new header is 1.5 to maximize torque.
The ECU does not need time to adapt to mods. It is constantly adapting in closed loop- part throttle and below 4000. In open loop - full throttle - it is set and does not vary. That is why a tune is important with mods.
No longer taking GTS Blue orders, because they want to make sure they get in all eight colors this year.
Every Viper has both traction control and ESP....just look straight down.......
The Comp Coupe and '06 street Viper have the same front engine mounts. However, the 2008 Viper has stiffer front mounts to handle the new powertrain. 08 mounts will fit in 03-06.
Mopar is looking into fitting the new twin disk clutch for 03-06 cars.
The only difference in the '08 seats is the addition of Occupant Classification System hardware. Seating position is the same as 2006
Finally-
Elvis works in our cal group........and we're always on the lookout for good bodies.....
Well I hope this helps. If you want details you can always go back to the engineer forum.
Enjoy.

Thank you for the report.
