    There are a few tuners that have done work with the Gen 5 viper with impressive results. Very professional, very good fit and finish compared to what I've seen come out of a certain tuners shop.

    Can anyone explain why they didn't go to an aluminum block for Demon? Especially with how far they took the car. Was it really a cost thing or were they worried about potential strength issues with trying it first on such a high profile car?

    I'm honestly surprised they didn't go aluminum with the introduction of the Hellcat.

    I guess they don't really need it but it would be a welcome addition in my eyes. GM went to all aluminum for performance cars starting in 98 (97 for the Vette) and I believe Ford went aluminum in 2011?

    Could any insiders shed light on Dodges reason for soldiering on with iron?

    Tim said the only carry-over from the Hellcat was the heads - but then mentioned deck-honing the block. Is it just a deck-honed hellcat block or is it all new from the start?

    Aluminum blocks CAN save some weight, but they cost money to engineer and to get them to work right. And then, you have to add metal in places to make it durable, offsetting some of the weight savings of using aluminum.

    Also, don't under estimate the durability of an iron block. Iron blocks can be made very rugged, and very durable, even under lots and lots and lots of stress.

    I suspect both of these issues are at work here.

    Likely part of the reason Ford and Chevy cannot touch the MOPARs power ratings

    Why go to the extra cost for only 3300 +/- vehicles?

    Alright here is the deal about the Demon. I got good information from a really good source, that it was a program error that came up with the 1,023 number. Only 5 people on the program knew about the true target horsepower number. Demon is exactly what it is, that showed in New York. 840 horsepower with race fuel, 808 horsepower on premium fuel, 500 horsepower with black key and 300 horsepower in valet mode. Most of us have been fooled the past few months with this "1,023" information. Sad to say, but it was almost a disappointment watching the Demon reveal that it wasn't 1,023 horsepower.

    The focus now is on the Charger and Challenger SRT HELLCAT widebodys.

    CGI Blocks offer far superior strength per lb as well.

    Although Aluminum is used on the highest HP per cube motors on the planet ( Top Fuel ) that's a "cost no object and replace them 30 times a year because they broke" type of thing. AKA Race stuff.

    Also, race apps don't need the same longevity as a OEM application. High HP at long duration will require more strength. To make an aluminum block that will last at the Hellcat/Demon levels would probably be a negligible weight savings over CGI honestly.

    About 85% of the Demon motor is specific to the Demon. Even though they are the same displacement they carry different internal codes.

    Seems like it would be money well spent as they could start to let it trickle down to lessor trims. It would have to shave at least 100lbs off of the front end.

    Why do any of what they did for 3300 vehicles?

    At least 100lbs would be shed wouldn't it? Right over the front wheels? Maybe the Demon would wheelie even higher :D

    I'm not so sure about that. 662 for the last 500 and 650 out of the latest Z and V. I doubt it's the block holding them back.

    Thanks, @redriderbob for the clarification on 1023. I was not disappointed cause when it pulled the front wheels, i figured how ever much power that was was enough.

    Thanks, so much to all of the people who kept this thread in line and got to enjoy if you know you know
