What type of coating is used on the exterior of the Gen II blocks. I noticed a section beginning to bubble near the thermostat housing. When I swapped over to the JM heads, I also noticed the coating was not on the factory cylinder heads. Is there a specific reason for this?
The Gen 2 block...
Nader: When driving i get an some "creaking" from my top when it is up. It sounds like it is coming from overhead and where the top meets the windshield. If i pull on the driver side handle on the top it stops. Does it need to be adjusted or tightened? Or does it need to be lubricated and if so...
Question:
Have any of you ever ridden in a supercharged Viper? If so, what did you think?
Several in the room have ridden in both SuperCharged and Turbocharged Vipers - Verrry fast and Scary fast in that order. Make sure the engine is properly modified internally if you are so inclined to add...

The '08 engine is SAE certified at 600 CBHP. The new SAE procedure (J2723) requires a 3rd party to witness the test and inspect the engine to make sure it is correct and a production engine. The driveline losses should not be significantly different from '06 to '08. The '08's should be more...
Although it is possible to move the Gateway Module we would have to test it in that location to be able to recommend it. There are no plans at this time to test a relocated Gateway module.
Snakeeye: Can excessive wind noise in the upper rear corners of the door glass in coupes be eliminated or reduced via window adjustments or other techniques?
If you have excessive wind noise in the upper rear corner the side glass may need adjustment. This area should be good. Some minor...
For '08 we needed to use ETC (electronic throttle control) for several reasons. At that time, there were no dual ETC throttle bodies available in the size we needed. Also, as the throttle area gets bigger, the motor has to be bigger/more powerful and that could have issues. We had 72mm single...
THe '03-'06 diff doesn't have problems. The '08 differential was upgraded to handle the higher output of the new motor. We went after improving the diff while we were in there changing stuff.
The Penalty for NAV is:
For the record: Nav will set ya back about $1800. With respect to weight:
*Hard Core Package vs. NAV w/Satellite is aprx 23lbs.
*NAV w/Sat vs. Base Radio is aprx. 1lb.
The non-ACR Coupe and Convertible went 202 mph, average in both directions to cancel out wind. The '08 Convertible went 197 with the top down. We had to go to TRC to go that fast. The Chelsea and Arizona proving grounds ovals are too small.
It is "breezy" with the top down though!
Another reply for Schulmann on differentials:
There was no difference between the '03 to '06 Viper rear differentials... all were the Dana Hydra-Lok type differential. The '08 Viper differential is an all-new GKN speed sensing ViscoLok. The ViscoLok has quicker response time and significantly...
