General Challenger DiscussionThis section contains general discussion about the Dodge Challenger. If it does not fit into a more specific area, it probably belongs in here. (Dodge Challenger General Discussion)
Here's the numbers I come up with per the controlled-rpm condition I cited earlier:
Code:
engine hp/L @ 2500 rpm
3.5 L 31.4
3.6 L 31.1
5.7 L 30.7
6.4 L 28.9
6.1 L 28.7
Viper 8.4 L v10 27.4
Honda vtec 2.2 L i4 25.0
Code:
engine hp/L @ 4500 rpm
3.6 L 63.9
6.4 L 62.5
3.5 L 61.4
5.7 L 61.4
6.1 L 59.0
Viper 8.4 L v10 56.0
Honda vtec 2.2 L i4 52.3
Why 2500 rpm?...well, reason suggests that is a very common area of rpm where people use these engines in day to day use. If "efficiency" is a concern, why wouldn't you be most interested in this range (where it is actually being used)?
Why 4500 rpm?...well, reason suggests that is a fairly typical area of rpm for typical engines to get a good swing at pk torque (which as a person in an earlier post cites, is a more direct quantity to indicate engine "efficiency", in the first place). At the very least, any engine will be way into the rpm's where the cam will be "on fire" (the vtec, maybe not so much, being a more extreme example).
The conclusion?...we are talking about a very narrow range of efficiency between these engines (they're all "equally efficient" within a few percentage points), but the 3.6 does come out on top, more or less. The Viper and Honda engines were added merely to introduce more context to the range extremities (big vs low displacement, highest hp vs lowest hp).
good info thanks...I was pretty sure I could count on you for some solid data

And the v8 challengers vs other v8s? Let's face it, if you're strictly buying based on performance, the Challenger is probably not going to be the car you buy

When you factor in cost, the 5.7l RT is the most bang for the buck.

As an R/T owner let me say I fully agree with this statement. If 1/4 mile times are your number one priority, buy an old fox body 5.0 for $4k, dump $10k into it, and for less than $15k you can run 9's all day long.
I consider my R/T a beautiful cruiser.
However, my R/T still has 400+ ft-lb of torque...My R/T can still rip off 5 sec 0-60 runs...and my R/T can still light up the tires at will and chirp the tires all the way through 4th gear...Can it beat a new 5.0? Nope, but I don't give a s**t

absolutely right - i didn't want to go in that direction since i was focusing on V6's.
but most people don't start with an LX V8 platform if they're looking to build a racecar.
the LX can be be fast, but the cost of making an LX V8 fast comes at a premium, just like the car itself.
