Viper X:
Another question on the ACR. It is likely that those of us that buy this car will run 18's all around due to a better "sticky" tire selection. What will we have to do to adjust the aero features, i.e. wing and splitter, to accomodate shorter 18" rear tires?
It would be impossible...
Another reply for SnakeEye on transmission shift throw reduction:
The shift throws in the '08 Viper transmission are reduced by about 20% compared to the '06 transmission. This amounts to a 0.75 inch shorter shift throw from 1st to 2nd on the '08 measured at the shift knob compared to the '06.
I know that I am going to get flack for this one. How about an optional power adjustible driver's seat for us grey beards? Bending forward or reaching down to the side to adjust the seat manually has its pains.
The Grail Keeper's seat isn't even cold yet and you are asking for a Power seat...

The ZR1 has a rear shock that allows the car to squat on launch without abrupt rebound. This appears to have been done to facilitate traction in quarter mile and shorter races/sprints. Any chance that this type of shock could be offered as an option on the Viper or does it also require...
j-rho: I'd like to know the front and rear spring rate differences between the 2003-2006 cars and the 2008. If the 2008 rates are appreciably higher, would also like to know if these parts could be made to supercede the old in the factory parts books. Such that if my stock coilovers...

black08: If it falls within their province, I was wondering if the SRT engineers can give us any definitive information on the alleged 75 horsepower Mopar package for the '08 as shown at the 2007 NAIAS?

The MOPAR package for the 2007 NAIAS consisted of: Special lower intake, Headers...
Q: Andrew/USPWR: Why aren't 5 point harnesses standard on the new ACR or even an option?
A: There are a lot of different driver preferences on racing harnesses. In fact, many owners pulled out the harnesses from their Gen-2 ACR and put in their own. We decided to focus our efforts on...
Regarding the rear "rattle" noise when cold out of the rear. It is very difficult to diagnose these things without driving the car. That said, it sounds like a shock noise if it goes away as things warm up. It doesn't mean there is something wrong with the shock, necessarily. Some are a...
art 138: Will the 08 differential and transmission be compatible with the 03-06s without major modifications??
Mopar is working on a kit to allow 03-06 owners to use the 2008 diffential, clutch and transmission. Stay tuned for availability
Venom 1000TT: On a 2006 coupe, what is/was the purpose of the crossover pipe? Should it be eliminated? What advantages/disadvantages would there be to removing it?
The crossover pipe is for noise reduction. With the 08 we were able to tune it such that it's not needed.
If you remove the...
viperflex: Will the 08 heads and intake work/fit on a 03-06? If so what kind of numbers would we see and poss time frame?
Mopar is working on a solution to allow 03-06 owners to use the 2008 heads and intake. The numbers from preliminary testing were impressive. Stay tuned for availability.
Reply for SnakeEye:
There is not a 3.33 ratio rear gear available from Mopar for the '08 Viper. In the past, 3.55, 3.73, and 4.10 ratio gears have been available, but now only the 3.73 is in stock. Order Mopar P/N P5007526 for the 3.73 gears.
700 RPM is target idle. Did the idle issue start before, or after the work done on the vehicle? How was the EFI cleaned? The symptoms suggest possible clogging of the injectors.
Sounds like your TPS (throttle position sensor) may not be providing the proper voltage to recognize that it is at idle. It therefore does not go into idle speed feedback control. Check your idle TPS voltage if possible, it should be no more than 1.25 volts and should be around 0.6 to 0.8 volts.
