Re: Challenger H/P rating
 

Is the 6.1 the 392 Hemi? I passed a new orange Challenger on the beltway this afternoon, and the tags said "RELIVN". LOL!!!

That seems like reasonable numbers. The 5.7L Hemi in a 2004 or 2007 Magnum or Charger is NHRA rated at 345HP, and the 6.1L Hemi in the same vehicles are listed as "ESI" - Engine Specs Incomplete.
The 5.9L Magnum Dakota / Ram engine was last used in the 1998 model year I believe and the 275 HP rating is approximately the same as those older Dakota or Ram trucks.
At 385 HP I believe the CJ500 Mustangs will have to "get out of second gear" (old Rambler song) to keep up with the Challenger 6.1L.

Mr. Warehime,
A 392 CID is approximately a 6.4L and is not what is supplied with the Challenger Drag-Pack.

Don't know about the Hemi's but the 360 is about 75 horse power below what it should.

About all the Mopars in IHRA Crate Motor Stock are below what they should be.

In reponse to the horsepower factor numbers released for the 360 Magnum motor in the new Challengers, Jeremy said, "Don't know about the Hemi's but the 360 is about 75 horse power below what it should." sic.

Wondering about what kind of engine specs could have elicited such a remark, I decided to go into the NHRA "Engine Blueprint specs" page and see just how this engine stacks up against the SBC motors and Ford Clevelands.

It's not there.

No specs are available from the NHRA website for this motor. At least, I can't seem to find them.

I have not seen any specs ANYWHERE for any of these new factory "Challenger" motors. To assume that it's just going to be an (IHRA) "crate motor" is assuming too much, I would think. Where are the specs for this engine, and how can we access them? Anyone know?

And, if they are not available yet, how can ANYONE think that the factor is wrong, if they don't have access to the mechanical specs that determine that factor?

I'm confused....

Then I think they need to hit that thing already if the cobra JET is not going to be able to keep up with it!! I mean come on the cobra JET is so horribly factored how can ANYTHING outrun it. I think the whole problem with the CJ is the badges it wears!!! R.J.

Re: Challenger H/P rating
 

Are the ratings listed in the first post for stock or S/S ??? (or both?)

Re: Challenger H/P rating
 

BTW has anyone seen this? Is that a Stocker Motor??

Re: Challenger H/P rating
 

The Challengers being "package cars" of which only 50 need to be built to be approved by NHRA DO NOT have to have the factory stock heads,intakes, etc, that a legal "stocker" is required to have.....they are required to have the parts Chrysler tells NHRA that they installed when they left the facility.....I have seen the engines in the cars and the hood scoop was required to clear the huge hi-rise intake and 4 hole throttle body on top, NHRA wants the scoop changed for the approval....The "07" 6.1 was rated 370hp by Chrysler and factored to 420hp by NHRA.....in testing the et. being run by the Challenger equates to approx. 600hp for 6.1 auto package....like the '68 package cars I think you will see a lot of attention paid to the performance of the new Dodge and Ford cars as everyone gets more time to tweak them to the max....the microscope is polished and has a big NHRA eyeball in it.....

Re: Challenger H/P rating
 

That Challenger does not appear to be a "package car" (you can see the factory engine on the floor...these cars are to leave the "factory" already modified ready to be personalized....the Indy engine is right from Indy.....probably a lot bigger than a 6.1 and has 2600 cfm of throttle bodies on it.....

Re: Challenger H/P rating
 

Do they have to build fifty of each? If so, I wonder how long it would take for each to be legal? Keep in mind that the customers got to choose which motor. I bet that most orders were for the 6.1.

Re: Challenger H/P rating
 

No one has been real clear on that yet....According to Chrysler the cars can be ordered by part # and there is supposed to be 6 part #'s......each engine with either a 4sp or auto......according to the rulebook the special run of "50" units says only on an already accepted "body" style doesn't mention drivetrain.....

Re: Challenger H/P rating
 

Tom, the horsepower ratings are for Stock class...Luke

Nobody has responded to this, yet, and I'm still wondering what the answer might be.

Jeremy (or, Jerry?)???????

Re: Challenger H/P rating
 

I think there will be a few 5.9's running .

Re: Challenger H/P rating
 

The engine specs will be posted soon by NHRA. The three engines are specific to the Challenger package car only and are not the same as the production cars.

Tom, S and S/S rating possible.

The transmissions available are a 5 speed auto or a 6 speed manual.

Re: Challenger H/P rating
 

Correct. That is Dave Duell's car and it was built from a V-6 street car. I saw it at the Indy Cylinder Head swap last weekend, it is one nice car.
