0-60 times sprint booster
Hello all again,
im just looking for a little bit of info if any 1 out there can help ive been looking at the sprint boosters and i know they get alot of slatting and i am a bit skeptical myself but from all the forums ive read every 1 that owns 1 loves it to peices and the only people who diss like them are people that dont have them i know they dont increase bhp or anything but what im really looking to find out is with sharpining up the throttle responce and all the other witch craft it claims to do does it actually increase your 0-60 times id be really greatful if some 1 on here that has a sprint booster fitted would come forward with some info |

Do you mean "increase" your 0-60 times or reduce?
I imagine it depends on how good you are at making flying starts, the biggest difference in 0 - 60 times in the competence of the driver & how brutal you are prepared to be with the clutch & gears etc. As far as I'm aware the Sprint Booster with make a difference to the way your accelerator pedal feels under your foot, reducing the amount of travel required from closed to open, probably about 2 inches of travel at most, I'm not sure how that is supposed to translate into faster acceleration. |

sorry increase the 0-60 my thoughts where if it was increasing throttle responce allowing you to get up the revs quicker it would improve your 0-60? could be completly wrong i really wouldnt expect it to increase by much would really like to see some 1 on here thats got 1 and has given it a try because to be honnest if the sprint booster doesnt give you any extra BHP and doesnt increase your 0-60 then it really isnt doing anything at all?
as i said im not sold on this sprint booster yet really want some 1 to come along and prove me wrong :P |

The Sprint Booster only affect the way the accelerator opperates - as a rough guide to the maximum time you could save, stamp on the accelerator pedal (engine off please) & time how long it takes to hit the stop - the car can't accelerate as quick as the pedal so the delay is with the car not the pedal or your foot!!

So you want to INCREASE the time it takes to get from 0 - 60, i.e. make the car slower? Not sure why you'd want to increase the time it takes but one on those crappy eBay devices would probably do it.

TMP thats my question just say i set a 0-60 time of 7 8 9 seconds or somthing " i havent tried it yet" and then i stuck the spint booster would this DECREASE lol or improve my time as if you read all the bumph that comes with the sprint booster its ment to increase throttle responce and i get what every 1 is saying about besically just mash the accelarator harder but if that was the case the sprint booster literally must do nothing then, as i said earlier really want to find out if some 1 has a sprint booster and if they have set any 0-60 times with the sprint booster on and off to see if there is any difference

There were some over at a Benz forum that had these. Most loved them. From what I understand they don't make the car any quicker but reduce the time for the full throttle/kick down effect on an auto.

The idea is that if you aren't quick enough on the throttle it'll improve that time for you. However, in my opinion if you aren't qucik enough on the throttle then you probably aren't quick enough with the brakes or steering either.

There is a little more to it than this.
The pedal of course is not connected to the throttle on most modern cars. The throttle plate is driven my a motor, a very fast motor. Even by pushing the pedal down as fast as you can, you still wont be able to do it faster than the motor can open the throttle plate. So, by speeding up the throttle pedal movement (by frigging it) you can open throttle faster. Much faster. In theory, it will make a small difference on a MANUAL car. My little Megane has a sport mode which does exactly this, changes the throttle pedal mapping (amongst other things). It's definately more snappy, you can feel it in the pickup and through gears.

He meant "improve" the 0-60.
I presume it works like the sport button in the E46 M3? That does a similar thing!

Is that the same thing as the pedal box? I think the guy from DTUK was selling them to forum members for around £160 IIRC.

My knowledge with the sprint booster is that it gives you better response i.e if you lighty touch the pedal a little, it would cause the car to pick up faster.
I think the whole logic is to improve pedal repsonse by constantly sending a faster signal or constantly sending a signal to the ECU ,saying that the pedal is pressed more than it is i.e when we push 1cm on the pedal then the sprint booster is telling the ECU something like 2.5cm??? As i know this box only do somehting to the signal process between the pedal and the ECU to give you a feel of the fly-by-wire throttle like the old cars. Probably works for cars that has low power and response that feels really dull, ofcourse some say that you can just mash the pedal but i think the aim is to have the car to pick up faster without mashing the FXXk out of the pedal.

I am using Sprint Booster in my E90 325 auto. The only reason I got it was because in D mode the throttle is a little 'slow'. In DS mode the throttle feels fine. However, I am not keen to drive in DS mode as it shifts at a higher RPM. Sprint Booster was a good solution for me. It only makes the throttle response more sensitive, is changes the throttle curve, nothing more. It's about feel.
