Help lopak make his 2015 Genesis 5.0 go faster

[lopak]

What all can I do that is not ridiculously inexpensive to make it go faster? No sprint boosters please

Ready....Set.....Go!

Hey, it works! On my way to and from work there was a nice valley where you could see the spot where the police sat. If empty, it was a great place to hit triple digits. Then it was an easy slowdown on the upside.

The most aggressive thing I'll do to this car while it's in warranty is keep it in sport mode. If I wanted more responsiveness I'd have bought something else.

Now, that being said, Pedal Commanders work. I know you said no Sprint Boosters, but I've owned a Pedal Commander and while it doesn't produce more horsepower, it can certainly make you think you added a whole bunch. Lots of settings. I had one in a Jeep Wrangler and it completely changed the throttle response, making it far more fun to drive. And that was a Jeep. I can only imagine how bad my gas mileage would be if I got one for my 5.0 (because I'd keep my foot in it).

What's wrong with sprint boosters?

What's wrong with sprint boosters?

I personally would say nothing in wrong with using a Sprint Booster to reduce the throttle by wire lag for a more aggressive acceleration feel.

However,the OP must have his reasons for not wanting to use the only tuning device available for the 2015-up 5.0 engine that reduces the horrible throttle delay programmed into the 5.0 electronic throttle system which will make his Genesis respond quicker as desired.

K&N performance air filters, premium gas, Sprint Booster, synthetic 75w-90 gear oil with friction modifiers, and full synthetic oil engine. Trust me, this few simple modification will have your Genesis moving very quickly even in ECO mode.

The 5.0 engine is very quick and is actually held back by the cheap looking paper factory air filters with a very small surface area(mostly a plastic plate) and a very laggy throttle by wire system(setup for smooth linear acceleration).

K&N(bottom) vs. stock(top) air filters comparison.


My GPS 0-60 acceleration time measured by a Torque Pro app while in ECO mode with Sprint Booster turned off. My engine only has the modification listed above.

"Feel" is a good description for these devices. That's all they really do; change the perception of available power. I know the Pedal Commander has a multitude of settings ranging from much slower throttle response to much, much quicker. I'm actually quite tempted to get one for mine, knowing what it did for my jeep's response. It could be unhooked if any warranty work was needed and I don't think there's anyway to see of a device like that was previously hooked up. Not 100% positive on that one without some real data to confirm it.

Haven't looked at the ease of access to connect one to the Genesis. I know it was a bugger bear to get it hooked into my jeep. I don't bend that way.

"Feel" is probably why the stock setting is so linear for a luxury smooth acceleration sensation that is not neck breaking. Yes, many owners like myself wants that pin you down raw acceleration when you press the pedal on a 420 hp sedan, but it does not make for a smooth luxury ride.

The stock throttle setting is still quick enough to satisfy most owners even if the delay slows the car down a few 1/10ths in a quarter mile run. I personally would like to lose those few 1/10ths for the quickest run possible, so the Sprint Booster works for me. However, many owners could care less about trying to make a luxury car a few 1/10th quicker for bragging rights. I am not one of them.

The Sprint Booster is very easy to install in the Genesis. Can be done in less than 20 minutes.

 

[lopak]

Thanks all. I'm not convinced sprint boosters work but understand to each their own. I was thinking about a cold air filter. Does anyone have a good brand they'd recommend?

I have wanted this car since 2014 but had just bought a Lexus in 2013 so I had to wait a bit. It was only a Lexus ES350 but I did test drive the GS and the Genesis blows them both away.

Seriously, there is absolutely nothing out there for the V8 5.0, don't waste your money on any aftermarket parts that says "you'll gain ~10+hp". I was in the same boat, I love the V8's and I wanted to make my previous '15 quicker/faster, though. When they introduced the V6 3.3 twin turbo, I jumped on it as soon as I could. Now I'm making ~450-480HP? and way over 500TQ and my best 0-60 run is 4.42sec.

Hey, I can not argue that turbo engines like your 3.3T are able to gain more power from a tune/piggyback module that increases the stock boost limits. However, the OP is asking about any mods for the V8 that will increase power even if the gains are minuscule compared to what the 3.3T is cable of obtaining by adding boost.

Note: I am curious to how long your stock internal engine and transmission will run before issues occur while you are making the kind of power you have it modded out at. Impressive numbers, but can the stock engine/transmission run a lot of miles maxed out like that before some major internal damage occurs? Personally, I would dial it back unless you are going to dump the car after a few years.

The V8 can run a 4.6 second 0-60 without over-stressing the engine with a few simple mods.

I like Sprint Booster, but they are many other brands available that does the same thing to be honest. Devices like the Sprint Booster brand just increases the voltage signal from your accelerator pedal to manipulate the throttle body to open at a lesser voltage than stock. The Genesis throttle only opens at 86% max(design limited) when the pedal is floored at WOT in stock form, but a sprint booster unit will allow the throttle to open to the max 98%(mechanical limit) by pressing the pedal halfway before the WOT kick-down is switched hence the better acceleration feel and performance.

It's not like I'm doing WOT from every stop/light sign, so I don't think the engine or transmission is gonna blow, c'mon. I run on Map 2 on 93 octane as daily and that is only ~4 psi of boost more over factory settings, which is around 12 psi. The only reason I mixed fuel, was to see how much more power we can gain HP/TQ/0-60.
As for the V8 running 0-60 in 4.6.... I'd like to see "valid" runs. It's either from a race track or tool/gadget that will show the elevation level. ~2-4% slope makes huge difference, though!

Well, you will just have to go by my torque pro app results. I am not going to waste time using other methods just to satisfy someone else which can be just as flaky and still leave doubts for critics. The roads I used to test my 0-60 were as flat as any roads in my area, so my Genesis was real world tested on the streets that I use. Good enough for me, since I will not be road racing my Genesis professionally. I will be competing against other cars on these roads for merging so I want to know how the Genesis performs on the real roads that I use daily even if the drag track would be more level overall.

GPS acceleration tests are similar regardless of the measuring device used. The high cost GPS equipment is more accurate down to the 1/1000th of a second which I do not need. Remember, all GPS data is acquired from the same GPS satellites in orbit, therefore mobile GPS data(phones ,tablets) is very accurate for performance testing to the 1/100th second.

Plus, drag racing tracks can have traction issues especially during test and tune events due to multiple cars using the track plus water used to help the pro-cars heat up the tires which make street tires hard to hook-up. In the past it usually takes a couple passes which could be hours to really get some good data a local drag track due to the waiting. That was before GPS testing apps, which makes needing to go to the local drag strip unnecessary just to get a good 0-60 time.


My 4.6 second run is valid. However, I will do a down hill run just to see how much of different it makes.

 

[Bourbonncigars]

Drive a 2010 Tahoe for a while before buying a 5.0. That'll make anyone appreciate damn near any 0-60 time.

How much will those mods cost total?

 

[carguy75]

How much will those mods cost total?

The mods I have done for better performance on my 5.0 probably cost me about $1500 total.

My mods that increased my 5.0 performance are summer tires(better traction), throttle body coolant bypass( cooler air charge into the manifold=more power), twin performance air filters(more air=more power), slipperier rear axle gear oil(less gear friction=more power) and throttle signal booster(less lag in throttle input=quicker engine respond time).

The best time I got with a GPS 0-60 tester was 4.6 seconds on a good launch with no wheel spin at my highest horsepower setting in sport mode, however my consistent average has been 4.8 seconds with less power(ECO mode) and less wheel spin with better hook ups.

My last and final mod for my 5.0 will be an mechanical Torsen LSD rear differential from a 3.8 Genesis R-spec coup. The Rspec rear axle has the same rear axle ratio as the 5.0 Genesis at 3.37. It seems to be a bolt-on mod without needing any custom work or ecu tuning. The LSD will reduce my 0-60 times by a lot(.3-.5 seconds) if it allows my rear tires to hook up at full power(Sprint Booster maxed out) in sport mode without the traction control intervening or the tires breaking loose. A used Rspec rear axle section cost about $500.

There really arent any good power adder mods until the 5.0 ECU is cracked. As far as I know only 1 company in S. Korea has cracked it. The problem with the Tau V8s is there arent that many of them out in the wild compared to the 3.8 v6 and the 3.3 v6t.
All I managed to find is a chinese knock off Hyundai ecu scan tool
