I had a 2018 3.5 eco boost , it towed nice but after the nightmare I endured for a factory recall on the Cam phasers , 5 trips total 2 after they lifted the cab off to do the repair, I sold it back to the dealer and bought a 98 Cummins Ram ...

They should “FORCE”, no pun intended, a Ford driver to put a ford motor in his heap. Not a hemi.

It is an excellent platform. If something happened to my Barracuda I would come back with a Mopar powered fox lol. Light, excellent suspension design, insane aftermarket. The engine compartment seems to accept anything with ease, especially stuff that isn't ford lol.

Die hard mopar fan here. No ferds for me! Kasse makes a great engine for a ferd. By the way, I hope you never hurt your hot rod. It’s a nice car.

It is, and for a long time I was a turbo guy and chasing goals.

Took me a long time to realize that while it's satisfying to reach a goal, it was much less satisfying driving that car on the street.

Sure if I met up with guys who did 2am blasts on the freeway it was fun but 99% of the time it's just frustrating because it's not usable unless you have a wide open road with no police.

I've since went backwards with much slower naturally aspirated cars and have much more fun with them.

Of course to each their own, just sharing my experience. That meaning, having cars that looked stock and trapped 150 in the 1/4, for me, were much less enjoyable overall than naturally aspirated cars with half or less the power.

That's relatable.

The Direct Connection Test car was a fun learning experience.
I don't feel it ever ran to it's potential but showed some possibilities to people
(and showed someone, back then, at Mopar was paying attention to "what was going on", to the growing segment of folks who have no interest in anything NA).

Not a single one of my own ideas or goals were used anywhere, it was all about whatever the engineering lead and my partner on the tech line wanted to do.

Knowing Fiat and Pietro, it wouldn't surprise me if they sent it to the scrapyard.

My horrible attitude aside, experience with that was plenty enough to tell me I wouldn't enjoy that setup for street use.

It ended up with a 440CI aluminum G3 with some ported prototype Apache heads that we probably weren't supposed to have, the giant turbo in the thread and so on.
Do that and you'll run way faster than we did because you'll spend way more time getting it right than we did.

I can see that point. My car runs 10.40s and is very drivable on the street. But it requires good road surface and lots of room to really beat on it on it, adding a cheater whistle for another 500HP doesn't make that any better lol. But more power, tighter converter, smaller cam, also has upsides.

If budget is a factor and you want to stay with a Mopar engine no doubt turbo G3, Eagle or Apache platform.

If budget isn’t a factor G2 Hemi with a blower.

I totally get it.

In my mind, the main attraction for the reliable, streetable 1200hp builds are if you’re using it for some drag n drive duty.
I mean, if you can’t actually “use” all 1200hp……..what’s the point?

It’s not that I don’t like what the turbo guys are doing, or that I don’t “like” them……..it’s mostly I don’t want to deal with all the stuff going on under the hood.

For something I’m going to own and have to wrench on……..I’m embracing dinosaur technology. A single carb and a basic electronic ignition.

100%. That's where I'm at w/ my cuda...I may run one or two more KOS races and then I might be going back naturally aspirated just to have fun. The KOS stuff is fun, but I'm nowhere near fast enough for most of those guys and that's fine. I have a street car...never wanted a race car.

Dont overlook the simplicity of the viper v10 with a couple mid sized turbos.

Sooner then later I will be moving forward with this unit. Plan on a couple small med turbos/cam after pro actively putting on better head gaskets.

Same here with my Challenger. Most don’t believe I drive mine all over on the street and 2 kits for at the track. To and from work, dinners cruise nights, car shows etc. Probably borderline streetable I suppose. Never have the time or money to do the drag and drive events, but it sure looks like fun. Turbo is the way to go for big power/streetability/reliability. Still gathering parts for my next twin turbo Hemi build.

Millennium heads,correct?

My buddy has a 2000 Corvette with a LS turbo set-up. Runs strong. Turbo is in the rear. Launches like a Vett, then the boost comes in and it hauls!

I'd stick a turbo on a 440 but EFI is mandatory. Carbs make u fat !

I am not 1200 HP But here is my story and challenges


Building Street Strip street car has been quite the ride for me, especially since I'm still pretty green when it comes to strip cars. Right now, I've got a F1X Procharger with the smallest pulleys, giving me about 15 lbs of boost. I have the pulley to really turn it up! and hitting higher HP sounds awesome, but I'm worried it might mess with how reliable my car is for street driving, and how likely the engine and trans are going to last... which is my main thing.

I've been trying to keep a good balance between street stuff and being fast on the strip. My ride's got a foot brake car, a tight converter, 3.54 gears, and it runs on pump gas. Plus, I've kept steel fenders/inner fender/interior and no lexan. I've hit some decent times, like 9.60 at 144 mph (very slow off the line with 3.54) and 6.15 in the 1/8 mile at 3780 lbs, but there's still room for improvement, especially with different gear ratios. (I did use race gas additive at the track)

One headache I've run into is cooling, especially on hot days or long drives. The engine gets way too hot because the Air to Air intercooler blocks the radiator. Street driving with this much power is a handful, too. Tires spinning out, even at higher speeds, keeps you on your toes. It's a blast, but I need to remind myslef to respect the power.

I've been thinking about ways to make things work better for both street cruising and strip racing. Maybe running without boost on the street and then kicking it in for the track could be an option. (relatively easy to remap the fuel injection system) Or ditching the intercooler to cool things down better with water/meth injection, even if it means topping up the reservoir now and then. I've even thought about stripping out some of the inner fenders for weight and cooling and high MPH handling, but I kinda like the look of a classic street car.

Going more race mode with 3.72 4.10 gears is tempting, and I am try9ing the 3.73 this year. Should really help 60 fts.
I am not an experienced drag racer and I'm still figuring things out, learning from each step, and keeping an eye on my buddy's setup with the twin-turbo BBC. It's a balancing act, trying to find the sweet spot between street manners and track performance. But hey, every tweak gets me a bit closer to that perfect mix.

Here are some pics

Because its a Mopar I had to make the brackets for the procharger myself. They really work well and are sturdy

If you think the car will handle more starting line ratio in low gear look at changing that ratio to a lower ratio, IE from 2.45 to 2.73 or whatever gear set you can find and like That lets the car cruise better on the streets also
I've done that in the past both ways, higher and lower, to help the traction on the starting line, test, test and tests some more
IHTHs

Never thought of this. Thanks Cab

It would depend on whether or not a power adder could or would be used. If you need to go naturally aspirated, I would get one of the new Keith Black 4.6 in bore Hemi blocks and put a 4 and 3/4-in crank in it, some millennium heads, two dominators on a tunnel ram, and a big old roller cam. That should do it.
If you're going to run a power adder, there's about a million different ways to get there.

If you're going to race in one of the drag and drive power adder classes, you are going up against some serious competition. It seems that anybody with a junkyard LS and a couple of eBay turbos can make 1,500 horsepower. The naturally aspirated classes are generally have a little bit more low hanging fruit.

I have always wanted a power adder mopar based engine. I am a bracket racer, and I like reliability as well. At the track we see a lot of power adder cars, and they are like one hit wonders. Everyone wonders when they are going to get a good hit and make a full pass. Been 9.40's with an NA Mopar and lots of 6.0's in the 1/8th in my bracket car. Been 9.89 in my NA street car, but hoping to drop into the 9.50s this year ..

Older Mopar engines seem to have a few issues when pushing them over 1k power levels. They are fine in 600-800 levels, but after that, issues arise. I think the G3 stuff would be way better at living at that level boosted. I have been using the cubic inches theory for a while, and these days, a stock V6 with a power adder is probably faster. So at this point, I feel like a dinosaur with my old Hemi.

I commend you guys for going the power adder route with a Mopar power plant. I would love to switch my cars all over to G3 stuff with power adders.

The Mustang with the Hemi is one bad unit, and I would probably do a build like that if the big Hemi ever sold.
