Being that the 6.4 is closer to the 5.7 than the 6.1 in the basic block casting I wouldnt think a new set of brackets may be needed. I hope all they need is a tune to release it to the public.[edelbrock]
The lack of a p/s pump also does not matter, the e-brock kit and any other superchargers I have seen uses its own pulley set up.
I have a R/T so Im thinking supercharger and an 6.4 cam/lifter/spring upgrade. That may be the best bang for the buck for an R/T.
Cast is certainly cheaper/easier to mass produce so it makes sense they'd go that route. I'd own a Edelbrock without question, but given the choice of buying new for the same price the billet KB is a no brainer. If I had to guess KB would have a hard time building the kind of quantity needed for OEM and that would drive a manufacturers decision as much as anything. I think the only thing missing from the KB kit is the nice preformed hoses, that would be a nice add.
I might be missing something but the KB 2.8 HEMI kit w/tuner is $6999, quick online search shows the E-Force w/tune is $7499. I'm sure they can be had for differing prices around the web but those show a $500 diff in KB's favor. Either way even if they're tied KB for the win. I do have a fondness for Edelbrock as they were one of the first aftermarket parts I ever bought for my first Mopar!
PS, were you looking at the upgraded liquid cooled kit? That's more expensive but the Edelbrock doesn't even offer that feature, although I'm not an expert on the E-Force kit so I could certainly be wrong...

I read all through the KB site, nice stuff!
The Following User Says Thank You to Justintime2 For This Useful Post:
If how they market the 6.1 kits is any clue, it will be available with or without the hand held. I am assuming (haven't verified this with Edelbrock) that if you buy the kit without the hand held, you can download their tune. You would want to run their tune since each one is CMR'd for the exact vehicle.
The Challenger running an e-Force pushing 700 horse was probably running the "Competition" Eaton. The Street model will make 100-150 more horse than stock, it has a three stage adjustment spring, if you are letting someone else drive the car and you want to lock out the boost, you can, because these Eaton TVS setups are internally vented and you can lock the bypass valve open (it's also vacuum operated).
To give you an idea of the quality in this "kit" here is the e-Force for 6.1 parts layout and installed.
With respect to the OP's question #1 there is no way in hell a tune is bringing the 392 even close to 525HP.
Also if everyone could see inside a billet vs cast blower system the quality and precision of the billet housing and rotors would be immediately apparent.
Hmmmm interesting because I agree with you in a sense 470hp and 525 is a difference of 55hp. What you have to keep in mind is according to the "Rumor Mill" 392's are underrated. people are putting up 415 and as high is 430 at the wheels. With a parasitic loss ranging between 11 and 20 percent that put the challenger at or over 500hp. Ask anyone and they will tell you "THE CAR IS UNDERRATED horsepower wise". Giving this equation it is not far fetched to say the tuner could put the car to its crate form because a tuner I believe can easily give you between 15-25 horsepower. I mean after all the 392 is the crate motor but detuned for us until Diablo rescued us.
