Sprint Booster

Faster Throttle Response

Sprint Booster makes your car's throttle respond faster to your foot. As a result, your gas pedal actually achieves a full throttle response 25% sooner than the stock configuration. Even if you have a 'sport' button, Sprint Booster will quicken the throttle response time. By making the throttle respond faster to your input, you will feel as though your car has more muscle than it really does!


• Sprint Booster does not increase Horsepower.

• Sprint Booster does not reduce your 0-60mph times.

• Sprint Booster DOES make your car 'FEEL' faster.

• Sprint Booster is not for everyone.

How It Works

Sprint Booster modifies the signal between the accelerator pedal module and the electronic throttle body. This modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening. This is especially evident in the low to mid rpm range where most cars spend their time on the street.

Sprint Booster simply modifies the throttle signal between the accelerator pedal and the throttle body. Big deal right? Keep in mind, this is the same concept as the 'throttle pulley' modification on cable based throttle systems - which was very popular in it's time. It doesn't add horsepower, but makes the throttle more sensitive and makes the car 'feel' faster.

It doesn't matter if you have a Sport Mode, ECU software, or 'Chip' on your car, Sprint Booster works independently of other modifications. It simply makes the throttle more sensitive, making the car 'feel' faster.

Is Sprint Booster for everyone? Of course not, no performance product ever is. If you have a track car where you spend most of your time near redline, Sprint Booster is not for you - Sprint Booster benefits are felt in the low to mid pedal travel. Some people don't like the fact that Sprint Booster reaches full throttle before full pedal travel - if you routinely mash the throttle to the floor, Sprint Booster may not be for you.

Sprint Booster is most effective in the low to mid rpm range, which is where most 'street' cars are driven on a daily basis. Yes, you may need to adjust your driving style after installing Sprint Booster - but that is a short learning curve. Sprint Booster will put the 'fun' back into your daily drive.

Sprint Booster is simple but effective - it makes the car more responsive and thus more 'fun'! This is why the product carries a 30-day money back guarantee!!!

Sprint Booster installs in minutes, and is easily removable. Plug-n-Play performance!

Just try it! Make your daily drive more 'fun'.

Everyone I know who installed one has uninstalled it. There's no performance increase, and simply behaves as though you put your foot down more than you did. What it seems to do is to change your throttle position, so at 20% TPS, it sends a signal for 40%, making it seem like the car is more responsive.

We messed about with this in Singapore around 4 years ago, and while it seemed useful in the beginning, people eventually realized you can get the same effect by flexing their right foot more than usual.

agreed agreed

You know, guys, I found this really effective mod that makes my car go faster. Didn't cost me anything, but my fuel consumption has gone up a bit, but hey, we're petrolheads, and petrol is still cheap in this part of the world.

I've learned that after shifting, applying the accelerator to the floorboards really really makes a huge difference in how fast my car accelerates. Not sure if this works for BMWs, but it's free, so there's no harm in giving it a shot :)

:rofl:

but why only after shifting??

[ghoonk]

Cos there's no point in flooring the throttle BEFORE a shift! :)

[Haissam]

but after a certain shift is also before the next shift :dunno:

:P

I've never heard of anyone ever uninstalling it tbh, but as I said, to each their own! I know E60's specifically have always gotten a lot of compliants for the sluggish throttle response. It was one of the first things I noticed when I test drove the car.

Sprint booster removes that hesitation/lag and makes me happy :).

Putting them on M cars probably doesn't make a lot of sense because their sensitivity is already a lot more on edge.

[ghoonk]

I'm not disputing the 'effect', but is there really a difference between using that and putting your foot down all the way between traffic lights?

Two snails under the hood, one bigger than the other, and I'll smile like never before :D




Damn you credit crunch!! :(

Yes, Flooring it from a stand still (again, E60 experience) and there is the same damned hesitation before the full whallop comes. Doesn't matter if I'm 20%, 40%, 100% throttle, hesitation is there. With sprint booster, there is no hesitation. It has a different /feel/. It doesn't make you go faster (like just giving it more gas), but just better responsiveness.

Make sense?

[ghoonk]

Yup. Does it by changing your throttle mapping using a capacitor and new map

[SewerSideUp]

But, there is a reason for that bit of lag on throttle respons.
The TB is operated via electric motors . BMW designed those to open slowly so the engine wont be guzzling fuel and NOT burning it properly before high RPM is reached. Old cars are an example. A blow of somke would come out when you floor it from idle.

Is this thing just a faster TB opener ? Without matching AFR numbers for correct combustion ?
In simple, does it just open the TB sooner without the needed amount of fuel from the injectors to cope ?

[ghoonk]

Good point, it is also possible that the ECU may not adapt quickly enough to the change in parameters (airflow), and this could cause knocking, which is not good for the engine. Hard to say if this is happening, so the only way to find out is when your engine goes out sooner than your friends'

hi guys..
I'm really so interested in this "Sprint booster"
do u reccommand me to install it in my 335 ??
and what about the gurantee ?? can the dealer notice that I have installed it ???
