Sprint Booster for the 2015 Genesis 5.0

[carguy75]

The sprint booster such cranked up(Race 9) provides so much immediate acceleration from a stop, it makes the car feel like the front wheels might come off the ground. Butt dyno approved

What i'm curious to know if it really does something we can't do with a heavy enough foot, and does that feeling of "immediate" acceleration really translate to "faster" acceleration.

Remember, the throttle opens to full as soon as the pedal is mash only partial way with the Sprint Booster. The stock pedal will only open to full when the pedal is mashed to the floor pass the kick down clicker. The delay of pressing the pedal to floor and waiting for the ECU to engage WOT is about a few 1/10th of a second of time wasted with the stock setup.

Like I mentioned, the rear tires lose traction in my car when I go all out in Race 9 in sport drive mode. So to be honest; the Sprint booster set to Race 9 does not give my 5.0 a faster 0-60 time in sport drive mode. Actually, much slower times like 5-6 seconds due to wheel spin. ECO drive mode and Race 9 is the fastest the car seems to go at 4.7-4.8 seconds on a good launch without losing much traction. However, my 5.0 does move like a rocket from a rolling start and at speed when the Sprint Booster is set to Race 9. I will need to use wider rear tires to achieve better traction in my car to fully utilize the Sprint Booster from a standstill going all out in sport drive mode in Race 9.

I draw the line there. I can live with a 4.8 second 0-60 car on the street without having to mess up the styling of the car by trying to make it a race car with wider tires. I love the stock styling of the car including the stock wheels.

LOL. The guy in this video pretty much sums up the Sprint Booster affects on the throttle pretty accurately so I decided to share. The way his engine responses in Race 9 mode pretty much is how it feels for me in my 5.0 Genesis.
Crappy video, but the review is spot on.

After more research, my car may have some kind of underlying CAN bus communication issue. Still, i cant ignore the fact that the issues went away when i uninstalled the Sprint Booster, so i wont be reinstalling it.

In my experience and limited testing, the Sprint Booster does not add power or even improve times. However, i cant stress enough how much it improved the day to day driving experience(set to Sport 9) when i was stock. That alone, to me, was worth the price of admission.

Since installing the sprint booster i replaced the intake tubing, installed k&n filters, and replaced the entire exhaust after the primary cats. Now that i've removed the SB, the car is still no slouch, even in Eco mode. Obviously, it take a little more pedaling, but now that i can hear the exhaust its easier to gauge what the engine is doing in real time. Driveability has improved, and when i really get on it, she sings and moves like no other. These are truly GREAT cars.

If someone with a more stock-ish vehicle would be willing to really test the validity of the Sprint Booster and post the results on here, you can have mine for free. Shamefully, There's not a lot of aftermarket support for these cars, so if i can help further the cause, i'm more than happy to do so.

0-60 tests are nice, but like Carguy75 said, due to multiple factors, the car's max 0-60 time is limited. So maybe someone can time their 40-80mph or 60-100mph, see if the passing speeds have improved at all. Just food for thought.

I can provide some 40-60mph,60-80mph,60-120mph,and 60-130mph data on my Torque app. The app does not have 40-80,60-100 specific tests.

That'd be great! Although, i have a sneaking suspicion that we wont see much, if any, improvements in full throttle tests. Seems like the Sprint Booster works its magic in partial throttle driving.

I did a couple 40-60mph and 60-120mph pulls on my way to work in ECO and Sport mode with the Sprint booster set to Race 9. The best time I got on the 60-120 pull was in Sport drive mode with a time of 12.5 seconds with me letting off the throttle a bit around a curve around 110mph before punching it again, so time should be quicker on a straight road. The best 40-60 time was 2 seconds in Sport mode as well with me running from a stand still to 60 mph in drizzling rain, so my 0-60 time was 5.7 seconds due to wheel spin.

I use my phone Torque app to log the runs so that I could not take a picture tonight like when I use my tablet. I will use my tablet for my next run.

Tonight on my way to work I decided to perform a good strong 40-60mph, 60-80mph and 60-120mph run since the highway was clear and the weather was warm.
I just used my phone app on the fly.

On a fairly straight highway with a slight curve I floored the gas pedal in Sport mode with the Sprint Booster set to Race 9 and got a 60-80mph time of 3 seconds; and a 60-120mph time of 11.6 seconds. I also got a 40-60mph time off the highway that was 2.1 seconds. So this car is very fast at speed without a doubt. Most cars that can do 60-80mph or similar tests in about 3 seconds are usually low 4 second 0-60mph cars.

Note: I also think that our cars will never be much quicker than 4.7 or 4.8 seconds from 0-60mph due to the torque management system which is controlled by the ECU that cuts power a low speeds to prevent drive-train damage; even if wheel spin is controlled since the system limits the torque.

My Cadillac has a similar torque management system that reduces power in first gear to save the transmission. My Diablo tuner adjusts the system to be less aggressive and shaved about a second off the 0-60mph time in my Caddy.

The Genesis 5.0 will never be as quick as it possibly could be from 0-60mph as long as the torque management system is active, however it does moves like rocket after about 20mph I noticed.

Here is quick snapshot of the Torque app log on my crappy laptop camera.

LOL. I have just noticed yesterday on my way home from work that my rear right tire pressure was very low compared to the left rear tire pressure when I was playing with cluster menu at the light. The left rear tire pressure was 37 psi and the right was 33 psi, while the front pressures was even at 34 psi. No tire pressure warning was displayed.

Well ,I even out my rear tire pressures and noticed on the ride to work tonight that car seem a bit quicker and handled much better on my commute.
Therefore, I will say that all the other acceleration runs are really not accurate due to the unequal rear tire pressures that probably caused the traction issues I was having, either by triggering the traction control or causing wheel spin when the traction control was off by allowing one tire to spin faster than the other.

I did not do any GPS acceleration runs tonight since I am tired on just burning my gas, however I did hand a late model Camaro SS its ass on a merge lane so the Genesis was performing well tonight with the Sprint Booster activated in Race 9 in the Genesis sport drive mode with hardly any hesitation from a stand still.

I guess having proper tire pressures can work wonders.

I am considering buying a Dragy gps perfomance tester, however I will only use it a few times to get good 0-60mph times on my Genesis. My main concern about buying the Dragy is the price for an essentially a one time use device since my 0-60 times will not change much on my Genesis 5.0 since it has the most engine mods that I will ever give it. So what 0-60 it makes now will be about it, therefore I will spend $150 just to learn that one performance number.

My second concern is that the Dragy 0-60 time will be very similar(if not the same) to the Torque app 0-60 time that uses my Nvidia tablet GPS; in which that means I would have spent $150 dollar for nothing. I really do not care if the Torque app says my best 0-60 time is 4.63 seconds and the Dragy says 4.628; the time is still essentially 4.6 seconds.

Anyone ever compare the Dragy to the Torque app?

Note: I use my Nvidia tablet since it seem to lock onto more GPS satellites(about 17 I believe) than my LG phone which only connects to about 9-11 gps satellties. So I assume that the Nvidia tablet gps is more accurate.

I've considered getting a draggy, too. I ultimately decided not to. For $150, i wouldn't get much use out of it. Intake, exhaust and wheels. Thats about as many mods are available for this car that affect performance. That and the torque limiter means my car is really about as fast as its gonna get... At least until i lose some more weight

Nothing for me to test at this point.

LOL. I will feel like a complete jackass if I pay $150 for a Dragy and still get the same(or similar) acceleration times as with the $5 Torque Pro app connected to my Tablet.

Yes, the Dragy is well regarded. However, so is the Torque app to an lesser degree.

The video feature is nice on the Dragy, but I will not be creating a video library of acceleration runs to justify the cost so that some members of a forum will believe that my 2015 5.0 Genesis can run a 4.6-4.8 second 0-60mph time with a Sprint Booster.

Um, the torque pro app takes great videos too. And with customizable layoute and gauges. Here are a couple i made in my Genesis and Avalon.

Well darn, I did not know the app could do that.

Now I really do not need to waste money on the Dragy. How does the Torque app numbers compare to a Dragy?

What was the best 0-60 time you got with the Torque app in your 5.0?

My best was time was a 4.9 sec when i first got the car... But i'm larger than the average driver, also.

A few mods later, i know it improved, but haven't tested it because of the issues i had with launching and the torque limiter at the track. However, I do want to test the 40-60, 60-80, etc since the torque limiter won't affect those times.

I forget that this car is a large luxury sedan first and sports sedan second. Therefore ,even if the Genesis 5.0 is one of the fastest large sedans on the street; it is still a modern luxury car with a boat load of electronic protection built-in to protect the drive-train from abusive driving.

I am cool with having a large car that does a easy 4.6-5.0 second(depends on traction the time) 0-60mph time by only pressing the gas pedal. The Sprint Booster just makes hitting the sub-5 second time that much easier.
