EZ,
We are using a very similar valve in our new SRT 6.4L Hemi without any issues. The valves have been bullet proof for us! As far as the LS7 issues, we can’t really comment since we are not familiar with their part.
Brent,
We are able to increase the transient exhaust gas temperature by 75°F and the steady state exhaust gas temperature by 50°F which is quite significant. This allowed a more aggressive fuel and spark calibration (see answer to post #9) for more power.
Marv,
The Pirelli tires for Viper are specific only to the Viper. The rear size, for example, are only the Viper tires.
The front tire size exists in other Pirelli tread patterns, but only Pzero and Pzero Corsa Asimmetrico 2 are the Viper front tires.
Almost every day!
As in, we drive the Nurburgring on Forza Motorsport 4 almost every day. :)
Seriously, do you really need to ask this question.
Stay tuned...
The new cooling system has improved efficiency and will provide uniform cooling throughout the engine. The normal range and fan trigger will be optimized in the coming months of development testing.
You can if you wish. Mobil 1 is great stuff! The Pennzoil is great stuff too, and we were able to be involved in the formulation specifically for SRT engines.
No certificates (talked about this one earlier). It looks like we will be able to give VCA members priority on builds, so if you put your up-to-date VCA member number on your order, then we will move it to the front of the line. Can't talk about roadsters yet.
Brent,
Only you would ask a question like this! The oil flow in the engine is unchanged from Gen IV, the filter could handle significantly more flow. The most interesting lubrication question is probably a new oil for SRT products, the new Pennzoil Ultra synthetic 0W-40. Shell/Pennzoil was a...
- We are looking at the carbon fiber rear applique to be an option on the GTS model. The body color painted rear applique will be standard on the SRT Viper and a black painted rear applique will be standard on the GTS Viper model.
- We are still calibrating the LC on the vehicle.
- The TC...
Pricing has not yet been finalized on the Vipers for any country, so we can’t answer that question yet. Since it hasn’t been finalized, I have no idea where $137K came from.
Chelsea,
We will officially rate the engine just prior to V1 with a random production engine. The rating could go up, could go down but we would expect 640 to be the number.
