If I had to do it again then I'd leave the exhaust alone. The shorty header like exhaust is good to about 600-650awhp according to a shop that I've trusted from the start who does almost nothing but SRT(8) Jeeps. In fact, I'd go boost 6-7psi with that set up. Any more boost than that requires forged pistons and probably rods. Keep the exhaust stock!

These engines are so efficient you'll only gain 10-15 hp for the 1500.00 cost of the headers plus the typical 1000-1200.00 installation cost plus within a short period it will throw an 02 late code which will have to be edited out.
Also you're taking your chances supercharging the 392 with the fragile cast pistons.
You'll need a tuner who has some good experience tuning these engines.
Mine blew at 6 psi on the dyno.
I eventually wound up sending it to Modern Muscle who tuned the Procharged 426 to 646 awhp.
You have to have money and should have at least 20-25k on hand if you're going to SC.
Plus the transmission will only handle 600 hp.
Ask me how I know.
After the transmission blew I detuned it from 10 psi to 9 psi.
Forged Arrington 426
It took so long to get the SRT back running I bought a 2018 Trackhawk demonstrator with 10,000 miles in March 2019 for 75k.
Then it got written off Oct 2 2022 when I guy hit my passenger 1/4 panel changing lanes at the last second and spun me into a guard rail.
The insurance gave me 2k more than I paid for it.
I still have my 9 psi SC 426 SRT
but I wanted an EV and didn't want to wait for the Chevy EV Blazer and decided to buy a 2023 BMW EV iX M60 with 600 hp at the wheels and 750 ft.lb of instant torque.
I took delivery in December 2022.
It will never blow the engine.
I modded the Fugly Grille as I used to be a bodyman and painter.
I also painted the black lower parts red to match the color of the car.

I actually do have two excellent shops here in NY that primarily just deal with SRT's all day. As a matter of fact the shop that put on the Corsa for me had 2 Trackhawk's and a JGC SRT in the shop while I was in there. The SRT was getting a supercharger installed. Both shops have done it many times, and they both have such a good reputation that I'm confident in their ability to do it properly and advise me of anything else that needs to done along with it so I don't have future issues.
I have quite some time before I can consider a supercharger anyway.
I'm a 1%er and my company did 42 million in revenues and I paid myself 400k last year so gas money is not an issue for me.
I paid 75k cash for my dealer demo 10k mile Trackhawk and the 120k for the 2023 new BMW so only spending 500.00 a year for electricity is just a nice bonus for me.
I still take my SRT out for a blast every now and then because it's nice to have a second car and I like the roar of a SC big V8

Nice, congratulations on all the success. I wish I could say the same. Unfortunately and fortunately at the same time, I was in the rat race for years and now I just enjoy a humble pension. The SRT was a retirement gift to myself and truth be told, I probably could have went for something more economical. Now that I'm retired I don't drive much at all, which I don't mind, it'll keep the milage low on the SRT and hopeful retain a decent amount of value. I'll be a slow moving project even when it finally goes out of warranty. The BMW is nice I bet it's features are insane. I haven't been able to bring myself to get with the idea of having to charge my car yet but the way all the car shows been looking lately, in a few years we may not even have choice.I'm a 1%er and my company did 42 million in revenues and I paid myself 400k last year so gas money is not an issue for me.

Side bar, I'd love to pick your brain on your journey to becoming part of the 1% sometime. I bet there's a wealth of knowledge you have to pass on to someone who's willing to learn.

My story is a bit unusual to say the least.
When I was 15 I crashed my dad's car into a ditch while skipping off a High Mass in a boy scout uniform
I hated these things standing for 2 hours and had 4 boy scout buddies in the car.
It's like God was amused and gave me a career from a fortunate accident.
Serendipity is my middle name.
My brother and I were handy and put together a compressor and got a paint gun and taught ourselves how to do bodywork and paint and wound up fixing and painting about 150 cars over 3 years including the neighbours we did for cost to bribe them.
$150.00 to fix and paint a rusty car was too good for them to resist.
Our parent's garage in 1977
Then we moved on to hand laminating fiberglass parts like spoilers and flares and 442 hoods among other things
which led to RTM press molding header panels for collision replacement.
The auto parts market was very cuthroat and we ran into someone who was looking to press mold safety tiles for the subway for blind people.
We did our first big job in 1994
Then we moved to the US and did tiles in various cities
And then for sidewalk curb ramps
Now we have 18 presses and make other stuff and are putting up more presses.
There's no reason for me to retire since I'm the CFO.

I didn't like the Fugly BMW EV M60 grille and the 2 tone paint so going back to my roots I made a grille cover
And did some pinstriping on the grille and added a front spoiler.
And added side skirts
And Mudflaps
Next step is adding subs and tweeters I still have to hook up maybe next week.
Built a sub box for the weird trunk

Wow that's crazy, that looks really good. The grille looks 100% percent better and the side skirts are nice touch too. The body work looks factory also, great job.I didn't like the Fugly BMW EV M60 grille and the 2 tone paint so going back to my roots I made a grille cover

I bet that sound system sounds awesome too. Are those two 12" subs in the back?
Thanks
All my mods are completely removable without a trace should I want to trade it in in 2 years when Chevy and Chrysler come out with their performance EV SUVs.
I'll wait until the first ones get past the catching fire thing
🤪🤪
BMW had 80 cars catch fire in early 2022 when they came out but they figured it out.
The grille covers are held on with 4 screws at the license plate frame which is 2 way taped to the grille.
the other ends are also 2 way taped to the oem grille.
The skirts and flaps can be unscrewed and the red parts painted black again.
The subs are 2 12" 800 watt rms with an 800 watt amp.
Not quite the 5000 watts rms with a 3200 watt sub amp in the SRT but
I didn't want to tax the BMW too much.
You need 10x the power to double the volume with car stereos.
Should be good enough with the oem B&W 1600 watt system.
My SRT system with 1500 watt rms subs feels like your hair is jumping from the compression when it thumps.

The first few cars I ever owned I built a custom music system into the trunks also but nothing as well hidden as your set up. I made sure the set up was all neat but my amps and capacitor were mounted to the rear seat and I built a custom box for the two 12" subs. Some people don't really appreciate how much work goes into a custom setup when you want it to look neat, especially when it's all integrated into the vehicle.like yours is. I like the way you even integrated the rear cargo mat into the SRT set up lol.Thanks

I thought about a custom system for the SarT but I didn't want to loose cargo space or my spare tire. I'm putting 22's on next week so maybe the spare can go. Haven't decided yet.
For the SRT and the BMW I built a custom box piece by piece as that was the only way to go to make it fit.
Originally added bass reflex tubes but it was too much so I went with acoustic suspension
And a wall for the amps and the LC2i line convertor off the back door speaker wires before I went with an Ampro Pac Harness which is the best way to go
Schoshe level controls for tweeters, front speakers, rear speakers, under seat subs and rear subs
The sub box doesn't need hinges and gravity is enough to hold it in place.

Wow that's a really extensive custom set up. The knobs up front to control the EQ is nice. I've only seen that type of set up in cars where they pretty much gutted a good portion of the car for custom speakers. They have some crazy set ups nowadays. I was at a BBQ this past weekend where they had a bunch of cars with concert style speaker setups that folded down into the backs of their cars. I would post pictures but I don't think I have enough post on this forum to post pics yet.For the SRT and the BMW I built a custom box piece by piece as that was the only way to go to make it fit.

Well mine is not a competition setup, just for fun.
I have the time to spend 40-60 hours on this
Some of these systems are so loud at 160 db that they will make your ears bleed so you can only turn them up when outside the vehicle.

I also added baffles I got on Amazon for the Hertz premium speakers.
The front door panels are 2 piece and can buzz so I used some 5 minute epoxy to fix them up

Well your system definitely has some extensive work for something that is not competition. I saw one of the cars at the BBQ actually remove their front windshield before playing music so it would shatter under the vibration and thought that was wild.Well mine is not a competition setup, just for fun.

The stock system in the SRT is definitely lacking a little. It was horrible in the Limited X I had right before the SRT. In the SRT I can't get the audio settings to sound good either. It's nowhere near as bad as the Limited X but it still needs work. Songs either sound like they have way too much bass or not enough. The volume also seems like it should be much louder even though it's just a stock set up.
You don't install custom set ups for others?
