Sprint Booster
Will anyone be installing a Sprint Booster on their 1 series? I for one definitely will. I have it on my Mercedes and it's a night and day difference. I can only imagine a 135i with it.
Here is the linky for more info http://cgi.ebay.com/ebaymotors/Sprin...2em118Q2el1247 |

This thing looks like a scam. If you read their claims carefully, it appears all of the below can be accomplished by flooring the car instead of pushing the throttle half way down (which the "sprint booster" will tell the ECU is all the way down).

I'm listed as a skeptic, fwiw. If throttle response is that much better, 0-60 times would be improved, they would have test results, and there would be a lot of talk about this product already.

I have it on my Mercedes. It works trust me.... It's not the same as flooring your car because even if you floor your car the throttle response is way slower than without the sprint booster. Do a search and you will see how many M3's and AMG's are running around with this.

It never actually tells you what it does, and I always asked w/ performance mods, why doesn't it come this way from the factory? (i.e. higher boost = less durability + higher power output). |

From what I have read on other forums it seems that what the device does is tell the car that the pedal has been pushed to the floor. It simply amplifies the signal such that the car thinks it should respond by running WOT. If thats the case, you could mimic this behavior by pushing the pedal to the floor, and save yourself a couple hundred bucks in the process. Also, how often do you take off at WOT? Not that often because the car isn't nearly as smooth or efficient. So by adding this you eliminate the car's ability to take off smoothly and add nothing (since it can be mimicked by pressing the pedal harder). Not for me, thanks.

1. Delays downshifts (useful) 2. Remaps throttle input (no so useful) I think all the "sprint booster" is doing is an extreme form of #2. Control of the throttle butterfly is pretty dead simple, not sure you can accomplish anything with a "booster" that tricks the computer. Again, where are any empirical acceleration numbers with and without this thing (on or off a dyno). Given how cheap testing this thing would be if it actually made a difference, it makes me wonder why there isn't a single number or graph on their website. |

eunosracr -> have you ever tried taking the device off and stabbed the throttle then putting the device back on and stab the throttle? I'm sorry but don't you think Mercedes spent many more hrs on the FBW system than Sprint Booster? EDIT: found some info on it.. These conclusions were based off an independent test. Quote:

That's exactly how i know it works, a little logical deduction. When I take it off the car and stab the throttle the car does not jump, i install the device stab the throttle and the car rockets forward. This is a case of dont knock it till you try it. I unlike the rest of you actually have it on my car and can attest to its effects trust me. Im not here to convince anybody as I have it and know its benefits. I was simply trying to let you guys in on a little known device which provides a much better driving experience (IMO) for a small fee.
:thumbup: So I guess all the BMW guys here http://www.bmw-sg.com/forums/engine-...dy-device.html are all suffering from dementia and some type communal placebo effect. And these other BMW guys http://www.e90post.com/forums/showth...sprint+booster Oh and all these Mercedes guys too, myself included http://www.bmw-sg.com/forums/engine-...dy-device.html Its funny how both of these links start of on the same foot as this one with a bunch of non-believers. As you read on you see people actually buy the darn thing and soon start to swear by it. I was a skeptic myself till I took the plunge. To each his own I guess. Cheers! |

Read their marketing stuff on their website, they are obviously making stuff up as they go along. A quote: The delay time whilst accelerating in 3rd and 4th gear and the engine in the mid-range, is almost zero. hahaha! Really, for every car? So it must only work with a tranny hooked up to it so the pixie dust magic works. These guys are cons. Everything about their website screams scam. It amplifies throttle input, thats it. It does nothing you can't do with your foot. Also did you see who owns this company? They sell tires. |

The car is launched already into the throttle, and you're back on the even as your foot is coming back off the clutch. We're talking about minuscule gains in speed, and gains in sensitivity. Throttle sensitivity has absolutely no effect if you are running at 100% throttle. There is generally a ton of room to dial up the OEM throttle tip in settings. Not that you'd necessarily want to, as faster isn't always better, but its not like the "gains" aren't there to be had. |

Hey John why don't you post his conclusions which pretty much support everything I am saying. The Sprint Booster makes the throttle 30% more sensitive. Get back to me when you actually drive a car with one and without one back to back. Till that happens your opinion means nothing. And yes the few thousand people that have this on their cars must all be crazy. In fact let me show you an email I got from a guy which I sold a sprint booster I had on my other Benz which I parted out to. Here you go. -----Original Message----- From: Rahmatulla Aziz To: eunosracr@aol.com Sent: Tue, 22 Jan 2008 10:28 am Subject: Re: Sprint Booster Angel, Thanks a million bro. I installed the sprint booster again last night and did a throttle reset and wow what a difference I feel like I have a rocket now LOL with only 168 poneys lol. Thanks for the help. eunosracr@aol.com wrote: Read the link below. Its super easy and makes a huge difference. If you drive in a lot of stop and go traffic like I do I would do the throttle reset weekly. Its your call. Check it out. |

But if you like the feeling of part throttle/quick lump of power, well maybe the device is for you. Certainly an easy way into making people think their car is "faster". |
