Sprint Booster Question
I've heard both sides about how all it does it just increases the amount of throttle with less pedal, while others say it wildly changes the car's responsiveness, but I just have one simple question.
There's been a few times where I'm stopped or rolling at low speed (<10mph) and need to make a quick pass so I mash the gas, but there is a very noticeable delay before it actually gets going. Will the SB actually get rid of this delay? Thanks guys.

You won't be disappointed AT ALL. I guarantee it 100%. All tunes/JB's/MHD. Blah blah are really cool but sprint booster will give you what your looking for. ZERO throttle delay and we need it for these turbo cars. JUST DO IT & PREPARE TO SMILE.

Most people that have them, love them. Most nay-sayers don’t have one. You’ll often hear people say you can get the same effect by simply pressing the throttle down quicker/further on your own. This is not true. Most input controls in your car have a range of motion that exact a response from some vehicle system. (Throttle, brake, steering, volume knob, clutch, etc.) These controls all of one thing in common. Part of what your brain perceives as responsiveness, is simply how that input is carried out (output) by the vehicle. Imagine the volume knob on your stereo. Suppose the volume could go from mute to max with only a half turn of the volume knob. That is, very little input creates a big change in volume. Now imagine the volume knob required 10 full turns to go from mute to max volume. This would be a very cumbersome, slow, unresponsive way of adjusting the volume, because large inputs (turns of the knob) result in relatively little output (volume increase). There are advantages to both a responsive and a less responsive system... A responsive system does respond faster and will allow the system to do more work(output) with less input from the user. A less responsive system takes more input, but allows you to make finer adjustments. A light switch is super responsive, but you only have on or off settings because of that (you can’t choose dim). Think about steering wheels/racks. Most enthusiasts like a quick (responsive) rack. Sports cars are expected to turn briskly and sharply without having to turn the steering wheel an exaggerated amount. If a sprint booster could be applied to a steering wheel, you would be able to turn the car sharper with less input from the steering wheel. ( a la Infiniti Q50 DAS or BMW Active Steering) Most BMW M cars have quicker steering ratios than their more plebeian counterparts. It is accepted in the automotive community that a more responsive steering ratio imparts a sporty feel. And it does. Still, there are those who feel the throttle can’t benefit from a quicker ratio. Just like the steering, volume, clutch, etc... the response of the gas pedal can be quickened or lessened. Some people like stock. Some want less response. Some want more. The sprint booster lets you pick what you like. By adjusting the “gain” or response of the throttle pedal, it provides an effect that cannot be attained by simply pressing the throttle further/faster. That being said 100% throttle is as much as you can have with or without the sprint booster. Top speed won’t increase, ultimate acceleration won’t increase. But you will have more acceleration for a given throttle input (at part throttle). BMW engineers a certain amount of lag into the throttle response. In addition, there is a maximum speed that the throttle valve can open and close.I do not know if those things change or not. I do know that the engine becomes much more crisp and eager to respond to throttle inputs (at part throttle) with the sprint booster. |
