Is The Genesis Coupe 3.8 Fast? 

If Your Interested In Picking Up Some Mods For Your Genesis Click Here! genesiscoupehub.com/

With enough money, there isn't a car on planet earth that can't be fast.

I've had my 2013 gen 3.8 coupe for over a year now, automatic, when you hit around 3,000 rpm, let off the throttle, push into neutral and slightly break, you will be pleased to know that your stock genesis exhaust will pop and sound amazing for stock.

Damn I can hear the disappointment in your voice don’t worry tho I felt like that too u just gotta tune it and you’ll really feel the difference trust me

Quick tip. In order to fully turn off Traction Control you need to hold it down for 5 seconds it will turn off Traction Control and Stability Control.

Yeah all you need is a cold air intake and a tune the Hyundai genesis 3.8 bk2 has been my dream first car since it first came out when i was 8 years old because my dad worked at Hyundai then and i got to go on many rides in the genesis coupe i love your videos man and will use them for myself when i get the 3.8 thanks for giving us entertainment during quarantine stay safe man

Also just a FYI. Your hot air intake is messing with your timing so you’re making less power up top because Of that. I tune these cars and it’s super common to see when 3.8 owners run short rams. Stock intake is even better with a drop in K&N filter but preferably a true CAI from 3point8 performance.

My family had a 08 Hyundai Entourage with the 3.8. Not even the same application or power from it, but the 3.8 was a beast of an engine.

you need to tune your car. if not done already. The stock ECU is for a stock car, so with all the mods done to it, without a tune its not gonna run properly.

If you added mods to your car and didn’t have it tuned it will almost always be slower! The stock ECU is designed to work perfectly with all of the parts installed from the factory. Your car might “sound” faster after mods but if you don’t have it tuned it will be slower. Go to a shop with a dyno and spend the money to get it tuned. Current 2013 Gen coupe 3.8 Track owner and love the car! Also, if you really want to make her a monster spend the $5,000+ for a turbo kit and get it tuned!

This is my dream car :) hopefully one day I will be driving one

Bigger, Heavier wheels will def slow the car down. It's def a nice car.

I’m guessing part of it is it’s hotter. Temp can seriously affect it. I have a 2001 corvette in winter I get around 4.5 - 4.6 0-60. But in the summer when it’s 100 out I get like 5 - 5.2 0-60. Also with my dragy I get invalid runs all the time if the road isn’t flat. Hope that helps. My car is pretty stock btw and I live in So Cal.

So bigger tires add rotational weight making the car have to work harder which would slow down your speed. You need to tune the car to max out your torque to get the most of having larger, more gripping tires. Hope this helps

Definitely get her tuned when you have the chance, youll see more out of your mods by then, i have a 2.0t optima, im waiting to get tuned after I finish up my intercooler setup, hoping to get 330whp out of it, that a goal number for me to keep the car reliable but pretty quick for a sedan but the genny looks good for sure 👍💪

Bro that manifold riser completely threw off your air fuel mix! Gotta get a tune, you got too much air and not enough boom boom juice

I drive a 1st gen Veloster Turbo and all the Genesis guys in our KDM group get smoked off the line but generally come into the power after 60 really fast. A tune would really help but the Genny's aren't the best off the line, that I've noticed.

🔥🔥🔥 she’s looking good bro

Drag is a pretty big factor when going from 0-60 so if you added any spoilers or bumpers or anything of the sort that could effect it

My friend there are a lot of variables that can affect your time. When is temperature elevation. Also I have a dragy as well they recommend that you mount it front to back not left to right. Worst of all it isn't unusual for mods to not work or make things worse. Another question would be is your fuel tank full was it full when you got your best times. Or was it close to empty?

Get rid of the hot air intake. Get a alphaspeed tune and you’ll see a difference.

The unfortunate truth is that naturally aspirated cars gain very little from modifications, I learned that the hard way. When younger I spent $2K in upgrades for my Celica GT-S and saw almost zero gains, a year later I spent $800 on an AWD turbo eclipse (catback $600, manual boost controller $50, and upgraded fuel pump $150) and saw great gains in power.

heat soak is your biggest enemy. i recently got my 3.8 tuned with stock intake and when my iat read from 45c to 55c with miami heat, my car feels really sluggish cause ecu cuts a lot of timing with those temps. on a breezy morning that i can keep my iat at 35-40c and i feel the car way more awake

i know the problem its automatic with manual shift at a higher rpm especially on second gear maybe paddle shifting can help

I have a 2.0t bk1 and it do think you need to tune yours I have cat back exhaust k&n thypoon intake and a turbo xs bov and ngk spark plugs hope you get her faster I would hope to see it in your next vid

You need to hit up alphaspeed for a tune, it really changes everything.

I literally just raced a 2020 10spd Camaro SS, video will be up soon enough💪🏽

The transmission doesnt like to be revved up like that. Launch from 0 not 2000. Hold the traction control for 3 seconds until it beeps twice. Then try. With a manual stock i was half a car ahead of a 2014 charger rt. When i did the exhaust, true cold air, throttle body, tires, throttle controller, short shifter and a tune i was pulling low 4s

The more mods without a tune can make the car slower especially with a hot air intake, you’re asking for a rod to come out lol. Also you need a tcu tune on that auto. Revving to 6500 vs 7200 is a night and day difference!

It’s slower because you put bigger tires and wheels on it if you put smaller tires and wheels in factory you’ll probably get better times because it takes more rotation for the bigger tires then it does smaller tires which equates to slower times

Ethan dude your car is cool now I see muscle cars trying to race me in my genesis because of you😞

Don't be bumped out. More mods can affect how the car performs. Mod's don't really start making huge difference till you get the Tune. Then you'll see a big difference.

Bigger tires will probably give you a false reading on your speedometer. Granted, it's probably insignificant, but when all the mods are factored in along with no mention of having the car tuned to these new modifications, the result is inevitably going to be slower times. The car sounds great though, and the butt dyno probably says you've got a race car now.

I think subconsciously I love this car because Im looking up videos about it after seeing one this week. But then Im like..this is deja vu. Then I realize I had seen this video maybe a year ago because I looked it up previously and forgot

You should remake this video now with the mods that you currently have

Gas weight matters, temperature, wind direction and most importantly, the road you're on. You last recorded by those concrete slabs. May wanna try there again? When I got tuned thats when all of my times seemed to smoothen out and become a lot more consistent.

ik this is two years old but if you still got this car ive learned that it’s almost like you get the best traction after 3rd

The reason for the "unverified" on dragy is you must of past a 1% downward slope. Basically trying to say you were cheating.

My boy really said I’m going to spend a few Ks to make my car slower 😂

Something wrong. I want to blame the road itself because you need smooth surface but maybe it's the new tires too. But yeah even BK1s are faster than that.

My man has an auto on a genesis and wants to see improvements...

You need a tune bro, but once you get it you will be way faster

Is your wheel and tire set up more heavier than the stock?

I also have a genesis coupe 3.8 and one of the problem with mine is the temperature the ecu in the genesis goes crazy when the temperature goes up even making you car slower than stock maybe you wanna try buying a cold air intake from 3p8 performance

How fast has 3point8 performance been on responding to any questions you might have had in the past? I'm wanting to get a tune from them in the future and sent them two messages with some questions through their website a few weeks ago without a response, I'm sorry that if this is a little off topic for your channel but I see that a lot of your parts come from them so I thought I could ask someone with better experience with them. Love your videos and the progress you've made on your car, looking to get there with mine someday.

hi, i know its late, the issue is the tire and wheel package, bigger tires and bigger rins usually means more weight, and is the total diameter is more than 3.5% of the original size the car being more slower in acceleration

Warm them damn tires up boiiiii

Bigger/wider Wheels/tires equals more rotating mass, equals slower... GET YOUR ALIGNMENT DONE!!! These are temperamental about they're alignment, loose is/feels a lot quicker but your always on the edge of loosing it, but it does hook and book(Drag strip mode). And if it's dialed in and within a hundredth of the center of tolerance, it will have just a bit of tire spin on hot asphalt but the car feels completely stable at "any" speed, on a race track of course :D. Plus other mods that aren't tuned, and the hot air intake like mentioned below. I bought the K&N 69-5310TS, and never had any loss, my only measured 0-60 was 5.23 seconds. But my best quarter mile run was 13.122 @ 113.4Mph. 2013 3.8 Track 8 speed, running 245/40/19 BFGoodrich Comp 2 Plus all season on the rear, Stock Bridgestone front tires, I now have 49K miles on it and it's on its 5th set of rear tires, General G-Max AS-03 245/40/19 installed October 2016, I love these tires it's just too bad they don't make them anymore. I had parked the car in the garage November 2016 and because of life and kids it sat in there until September 2022, grabbed a battery and 5 gal of premium and pulled it out, and now it's kinda back to it's mostly summertime weekend playing, and needless to say I am harder on these tires than I was to all of the previous rears combined and they're holding up way better than I expected... Also try different gas stations, as some aren't very truthful about what the octane/ethanol content is. Then get some CRC GDI intake valve cleaner, or whatever other brand you prefer that makes a similar product and follow the directions, maybe read them all first then do what it says... I got my Genesis brand new, and other than a battery and an alignment 2 or 3 times a year, it's been a great car, Anyways I hope your still enjoying your Genesis!!!

How often are you guys having relays fail?

The folks talking about getting a tune are probably right on the money but 0 to 60 isn’t the whole picture. It may have a higher top end or midrange because of the mods. The power curve is different now I’m sure. Genesis aren’t exactly lightweights nor do they have awd either but 0 to 60 isn’t the be all, end all of performance. That said, yeah, modern cars, especially Genesis coupe need a tune to be their best.

Did you use the dragy on the last video? I can’t remember.. If not, that’s a variable that would make it not accurate

Is it better to get it in manual or automatic? I'm debating on grabbing a 3.8

The throttle controller gives you a quicker responce but makes the car loose power in the top end.Everyone i know has the same problem

I just noticed this now but you might notice a bigger difference with more gas. You were close to empty even when first starting. I would try again with a full tank of premium

needs a tune bad. all them bolt ons dont really add much until you retune for it.

It's 84 degrees out and it's pretty damn hot Me in Texas working construction in 109 degrees every day 🧐

Getting a tune really opens the car up. Got an custom tune from SFR and gained 37whp. The throttle response is so much better since the tune.

Damn bro you did like twenty 60 rolls and got the same time every time... at least you tried 🙂 😌

what kind of headlights and taillights do you have installed they’re super cool might but them

Definitely tune it bro my 2013 2.0t with stock turbo is high 4 second 0-60

That car a beautiful 👍

What are the specs on those wheels and tires?

Remnant performance sells turbo kits for $3,300. I’m getting mine In January 😈😈😈

what tires are you running? and are you turning off your abs? times are terrible lol

I thought they say new cars anytime you add mods..it useless without a tune..some say if you added 6 different mods at once then tune it'll be totally different car

You need to tune it plus bigger tires can slow it down its not slow at all

Where did u get the side skirts?

I have a 2015 3.8 ultimate and I never do this. Sometimes I get it to 4-5k rpm and its fun. Maybe ur car was faster before you killed it.

This needs an alphaspeed tune lol

Should I get this or a SI 2020?

I think the heat is your enemy here. My Geni Performs best if cooler weather. As do all naturally aspirated engines. What was the temp in your original runs

Probably not enough backpressure from the new exhaust on the stock tune

Alphaspeed tune it 👌🏽 you’ll see more gains.

It depends idk what you have done to it but I know it depends on which headers you add to your car. Some headers you’ll gain more low end power and lose more top it , with others you may gain more top end power but lose more low end. Not sure if you’ve done headers but maybe the reason it’s slower before lol . Nice car tho

Need a gear change now to a slightly lower gear ratio

How's the gas milage for a daily?

From what I can see you did a few things that slows your acceleration of wich is increasing your tire size among other thingd in the comments.

You needed to retune the car after all those mods

If it had a backup camera I’d definitely buy it but since I don’t know how to park backwards without the camera, I may have to get a g37s coupe instead.

Have you compensated for altitude, weather, etc?

Hot air will cost you power. Try it in the day and then the evening Are your new wheels the same overal size, rolling radious

Can a bk2 beat a g37 sedan stock for stock?

If you haven't had your ECU Tuned,& your launching your 3.8 like its a Funny Car..you are beating the purpose of all the Bolt Ons & destroying your ENGINE! All of your comments are telling you to get a proper TUNE & SparkPlugs.. Read & Heed their ADVICE, because they're only trying to help..& you're very welcome 😉

Man these are suppose to run 0-60 at an average of 5.2 seconds..not sure why pretty much a full second slower. Probably needs tuned. Mine has a bunch of bolt one and I need to take it to PA to have it tuned because im only running mid 14s at the track with the 3.8 and thats almost a second slower than it should be running. Somethings wrong. Lol

If you put on giant wheels.. you changed your gear ratio.. keep the stock diameter

Weight ??

What my tuner told me is that you should of tune the car before you started to mod the car might help

Bigger diameter tires = slower acceleration

What city are you in

60mph right ?

Not what I expected, my 15 sxl optima will do 6.4 😂

Whats the app you are using for your testing

Notification gang 🔥🔥🔥

It is ok to floor it on S/D but not recommend. It's sooooo wrong to let off the throttle after a pull in S/D, you're damaging the car that way. Use full manual mode at all time. Also, you cant expect a good time if you dont set the gear you want to start a rolling pull, you should hold it at 4.5 RPM or 5, then floor it. When you let off the throttle on auto modes S or D, the gearbox slams into next and next gears without compression on the torque converter and load to the gearbox, that damages the gear.

What size wheels?

Mods do nothing without a tune...

Can someone tell me what year this genesis is?

Your widows are down bro.

Make a video on the car if it is expensive

I Need Someone To help me with info on ecu tuning for 3.8 azera limited... Help I've went cold ram air and almost full straight pipe just still have my exhaust manifold cats.....
