I figured I would update on the build and start a new thread ('build has begun' was the original thread)...
I will post the dyno sheet Monday but figured I would get the discussion started.
Injected Engineering in Georgia did the build.
2019 Dodge challenger R/T with 2500 miles.
Car put down 760 to the wheels at 12PSI.
The tuner says the car definitely has more in just need to turn up the boost but he was confident she is virtually bullet proof at this setup. And shes a beast right now!
Heres a quick run down of parts and pics of the build sheet.
I'm very happy, just picked it up yesterday and didnt get to drive it too much but a couple 2nd and 3rd gear pulls all out was intense!!!

Outstanding build! Just sort of thinking that while the Mopar side stripe looks nice, the R/T classic stripe might add a little more "in your face" attitude...especially when you wax some unsuspecting Shelby or ZL1 pilot...lol
Those are incredible numbers! Yes, I agree about making it a sleeper. Most car guys know the stock horsepower numbers of the 5.7. A few years ago, I owned a ‘12 RT with a supercharger set at modest boost and was somewhere around 550-600 horsepower. The car had the RT Classic stripes. I was on the highway and a cocky yuppie couple pulled up next to me in a Mercedes sports car. Kept wanting to race. They finally punched it to take off and even with a headstart, I caught up and passed them like they were standing still. They hung way back for the rest of the drive on that stretch of road!

In what part of the country are you located? It would be great to compare notes with you.

Nice job! I am curious about retaining the stock bottom end internals. I know for my year engine that was a “boom in the night” waiting to happen so we forged the whole bottom end. I’m not sure if in your year the bottom ends are built more stoutly than earlier 5.7s. If they aren’t, I would echo other suggestions that you get a second or third opinion on the bottom end. Might save you some serious headache down the road.

btw - when you get a chance - post a video of you getting into it with your beast - especially if the thrill of the ride has you squealing like a 5-year old little girl!!!

Forged pistons and rods are done.
Crank stayed stock.
The build was done with discussion amongst all these tuners. Injected does know the guys at HHP, the pistons and rods are from MMX and Hellion was a close part of the build along the way. It took about 5 months to complete.
If it wasnt on E85 we wouldnt be pushing this much. A lot of this project is a test, we and Hellion wanted to see what could be done and handled on this setup because as far as they know it hadn't been done on a 5.7 M6 w built bottom end. We would have handled the bottom end slightly different if it wasnt such a low milage block.
If something goes wrong w the crank I'll keep you all posted.
