It was mainly installed for the Quad Cab SRT-10 truck. This vehicle has towing capability and the sensors were installed for engine protection. They are there by default across the rest of the Viper-powered line-up.
600hp Hemi V-10 for the new SRT Coupes!

Ivan--Possible business explanation for no initial hp increase in the new coupe might be the large supply of new SRT-10s on dealer lots: They'd sit even longer if word got out of an upcoming 100hp boost just around the corner.
IMHO, Ralph's got the back end of the new coupe looking great....now if DCX would've just let him tweak the sides the same way (i.e., just bring back those perfect Gen II lines and ditch the 1/2 Viper 1/2 Vette side appearance)...

Jeff, the reason for the inventory for the SRTs is because DC wanted to increase production without and additional orders. Orders have been the norm, about 1800-2000 per year and has kept at that pace. DC comes along and said "Hey, since our QC is amazing on these cars, let's bump up production"; thus the inventory.
Oh, almost forgot the most important quote from last weekend by Dan Knot himself referring to the next Viper package. "It will make children run in fear."

Whew...with hemi heads. 20 spark plugs at a clip....WOW
Hemi is really a generic term. SOOOO many heads on the market have somewhat hemispherical heads. I'll explain my ignorance - does the 8.3 liter have and "domeing" of the heads. Is that what they are referring to? I mean for crying out loud a Camry is a "hemi".

Was he referring to its looks?
We don't know, but I think he happens to be referring to the over all car performance included.

Ivan: Thanks for the info. Very plausible explanation. Maybe it's just a temporary buyer's market??? As for the next engine, I'd imagine that in addition to a major HP boost, emissions requirements will play a major role too?

I'm not sure the Viper V10 could just have hemi heads added to it.
Pushrod engines are hard to convert to hemi if they were not designed that way to start with.
The other thing to keep in mind is that there really isn't anything magic about a hemi.
A hemi chamber will often let you have a little higher compression ratio and that's really all you get just for being a hemi.
An engine designed for high output can be a hemi but it doesn't need to be a hemi.
The valves pointing in all different directions are a nightmare for pushrods.
Most of the talk about "HEMI" these days, is coming from the DC marketing people.
They are cashing in on the reputation of the old hemi.
I don't see the new Dodge hemi V8 out-doing anything that GM is has with their V8 in the Z06.
Don't get suckered, hemi doesn't mean that much, engineering for performance does.

Hemi doesn't mean much? ? ? ?
Hhhhuuuuummm?
Not legal is NASCAR? WHY?
Banned after 70 in nascar after they dominated. WHY?
What motor is in top fuel? Funny car? yes, there are other similar versions by other brands.
Very simple. A hemi by nature is not emission friendly(2 plugs) however a very efficient motor and tends to work better at higher RPMS. The old ones would just keep winding until either the fuel or the cam maxed out. BTW, Hemis love blowers.
Today they are playing off of the old name, however this design is arguably the most efficient high output design.
Keep in mind the olden HEMI did not start off as a monster, but sure ended with TONS of respect until insurance and emissions killed it in 71'
Viper V-10 HEMI may just be the beginning.

The old Hemi was indeed a great engine. It was a great engine and it was a hemi.
As you say, the old hemi didn't start out as a monster. It was chosen by racers of the day because of its strength its size and perhaps because it was a hemi.
Much development went into that old engine over the years. It became one of the engines that was used by so many people that many manufacturers of speed equipment developed special parts for it and it became even more popular.
That sort of thing feeds on itself.
The Chevy small block is another example of an engine that followed the same path.
When I say that there is nothing special about the hemi, I mean that the hemi chamber will not get you much of anything just because it's a hemi.
There have been many very ordinary engines over the years that were hemi.
There is room for big valves in a hemi. Of course, you have to have big valves, not just have room for them.
If you design the head with great ports, you will take advantage of those big valves and make plenty of power.
NASCAR banned the hemi because it was an engine that did the things I mentioned above. It made more power than all the others. But not just because it was a hemi.
NASCAR is in the business of putting on a show. They will not let one brand run away and spoil the show.
American stock car racing is not a development class. If some brand has an advantage they will step in and make them even.
There isn't any reason that a hemi should have problems with emissions.
There isn't any reason that a hemi needs two plugs per cylinder.
So,
What I'm saying is that a hemi combustion chamber is good. But that in itself will not make an engine better than non hemi engines.
