Naturally Aspirated vs Turbo

[Eyestinger]

Hey guys, I recently traded in a V8 375hp Dodge Challenger for my Stinger, & I love it.

But one thing I used to really like about the v8 is that instant response off the line felt really nice. Burn up the tires all day long.

Now I know turbo lag will never be the v8 naturally Aspirated instant response, but what are the most practical upgrades to get back more of that quick response?

Intake, exhaust, intercooler?

There’s no turbo lag on the Stinger. This thing is way quicker off the line than my previous 6.0L V8.

 

[Roarbomb]

there are some computer "Safety" features that may limit your ability to wheel spin, but its definitely not the turbos lagging.

SSR secondary cat deletes offer the most bang for the buck for hardware. JB4 offers the most bang for the buck in the tuning/piggy back world. There are now a bunch of good intake options and more inter coolers are coming out as well. The Stinger should be faster than your RT Challenger. Those things have some amazing sounds though!

I just had a moment to look at the JB4, and it says it adds 100 horsepower just by doing some computer modifications! How is that even possible? I didn't add an intake, I'm not adding larger pipes to let out more exhaust, how can a computer modify electronics and add a hundred horsepower?!

More boost.

More boost.

What does that even mean?

It increases the amount of boost the turbos produce.

Is there a more technical explanation on this? Like why isn't it set up from the factory like this? What's the disadvantage of more boost?

Not to be funny, but you might want to search some of the threads. Simple explanation is...

The factory balances longevity and generic tuning to fit 87-93 octane. Start adding boost and you’ll need to make sure you stay up on service intervals and you’ll likely have no problems. I’m assuming this is first turbo car? If so read some threads and articles... you’ll do better with it long term.

Not too sure but, this might help you out.

Not sure if it adds 100 horsepower but it does definitely make the car faster....Simple explanation all the BOX of wires (JB4) does is turn up the boost on you car....It does this by tricking your car ECU making it think it has the normal boost level while is giving it more boost hence you make more power....100 horse seems a bit exaggerated on a stock car but who knows....There many piggybacks out there...LAP 3, JB4, and others just do a search....

There are pros and cons to running a piggyback just search this forum there a lot of information....If you do install a piggyback make sure you put in colder spark plugs and gap them properly....

Welcome to modding factory turbocharged cars. Most car makes err on the side of safety with tuning and leave a LOT on the table that a tuner can take advantage of and pull out plenty of power while leaving the car mechanically stock. Raising boost, a bit of timing and leaning out the AFR's a little can go a long way. As far as oomph off the line..This car makes more torque at 1500 RPM than a 5.7 Hemi makes ever. More than likely you're seeing the ECU limit wheelspin or torque limits if you're just jamming the gas and not in Launch Control/Sport mode.

 

[TwinSnails]

^^^This, put it in sport and disable traction control when everything is up to temp

 

[CaliSting]

Stinger makes more torque at lower rpm than Dodge V8. Lag is related to Kia nannies trimming throttle not turbo lag.

Trimming throttle? How can you avoid?

Trimming throttle? How can you avoid?

With the car stock, slap it in Sport mode and turn of Stability/Traction Control. Thats about the limit of getting rid of any throttle control nannies you can do. The car will still step in, but only at 9/10 of the limit of driving when your getting a little 'too' sideways.

Unless you go full ECU flash, you won't remove the throttle control from the ECU at all, and honestly, unless your going full on track mode why would you? The car does a pretty dam good job for launching, but it will hold back a little. The best explanation most of us have been able to figure out is that it saves the tranny and differentials (AWD) from multiple hard launch control launches.

Once it's broken in, put it in Sport mode and disable traction/stability control. Stand on the brakes, watch for 'Launch Control Active' to pop up on the dash. Floor the gas and then let off the brake. You'll never utter the words 'lag' again for the Stinger and you'll have a perma-grin that I still have almost a year into owning mine.

sports mode and using the paddle shifters will eliminate the vast majority of the throttle delay. There is some turbo lag, there's turbo lag in every turbo car, but it's very very minimal in the Stinger. If you're in the right gear when you floor it, the response will be quite close to your last V8.

Every car manufacturer "under tunes" their cars from the factory. Kia has done this even more than most on the Stinger because of the ridiculous powertrain warranty. That's why you can mod a Stinger to have over 500 crank hp with just a couple thousand bucks and some E85.
