I think this is more of a design choice by MB rather than something that protects the engine. Engines have, for a long time now, rather effective rev limiters that protect the engine under acceleration. I've ridden many manual transmissions to the rev limiter many, many times without any issues. I suspect MB does this for the non-AMG models because hitting a rev limiter is a rather abrupt experience -- you go to nearly full acceleration to zero acceleration in an instant -- and it would not be consistent with a "luxury" ride.
The more dangerous issue is downshifting too early, where the momentum of the car will push the engine revs over the limit (a rev limiter is ineffective here). This is an issue for full manual transmissions, but probably not for any modern automatic.

You are a sponsor here on the boards and i dont know what product you are selling nor do I know if you have an alterior motive, but I am just a board member who has had the product from when they first came out. I am not a rep of the company just a member giving another member my experiences on a product.... This product WILL eliminate this issue of throttle lag... MY E55 desprately needed it and I the throttle response should come like this from the factory....
Thanks..

When I bought mine, it didn't have the fancy buttons with various settings. You just plug it in and GO. My car did have comfort mode and sport mode, and I drove mine in comfort mode with SB installed. Sport mode was very agressive....

OK here are the results on a the Sprint Booster for a 2011 E350 4matic... It works GREAT!!!
It won't be for everyone (but if you are reading this, then you are probably interested anyway). If you just want to casually and leisurely go for a drive and aren't into speed, don't spend the money. If you want to lose the lag and get off the line faster...this is an awesome product. It has 3 modes...(Clear) inactive for when the wife drives it
,(Green) when you want a little boost and, (Red) for some serious pick up. As people have stated...it apparently does nothing to make the car faster, it just loses the accelerator pedal lag time. Whatever it does...it sure makes the car seem like it has a lot more HP and it is much more fun to drive!!!
Installation took me about 20 minutes (just because I was nervous about "F"ing it up). It was real simple and went very smoothly. I have attached some pictures with notes. I am also attaching a PDF of some installation guidelines for a C series I found on the web (it's the same steps for the E series.
Hope this helps anyone that was thinking about adding the Sprint Booster. I have become a big fan. One of the best after market additions I have done. Enjoy!!!

E550 2010
Since making the transition from a manual sports car to the E, I have noticed from day 1 that there is a huge engine that I find a bit difficult to tap into without stomping on the peddle.
So, I've ordered a sprintbooster. I'll post a review later on its affect with the 550 engine.
btw. sprintboosterusa.com doesn't take amex, and when I gave it my visa, it repeatedly rejected it. So, I went through sprintboostersales.com in NV. Sale price is the same everywhere.

True...but we are not talking about a big increase but, in my opinion it will feel faster which is more important. By using a combination of manual shifting and catching throttle pickup in the next gear just right it will really put a smile on your face.

Very true. When I turn it off now, the car seems anemic.

E550 2010
Sprintbooster is not working out for me. I received nor but it didn't fit. I sent it back and got another from a different vendor and still doesnt fit!
The problem is the connection between the sprint booster and the oem cable, not the accelerator . I am unsure if the prob is the plastic molding or the flat sprint booster leads trying to fit in the round oem female part. Anyone else run into this? At this point I am assuming sprint booster is not compatible w the 2010 e550.
Any suggestions?

E550 2010
Alas, the rep said I had the right part #, but the techs at sprintbooster did not get back to me. They said they didn't think it was a bad batch of products. So, I again returned the product and my conclusion is it doesn't fit the 2010 w212 e550.
ftb if you take the risk of trying one yourself, let me know what happens. ps i'd try to find someone who will pay for the return shipping and does not have restocking fees.

It seems to me that all this product does is reduce the travel range of the gas pedal and give you less control over gradations of acceleration. In other words, one inch of travel opens the throttle more with the sprint booster than without. Or put another way, you reach 100% throttle at 3 inches of gas pedal depression with versus 100% at five inches without. It's kind of like having a stepped volume control with 100 steps and then changing to one with only 50 steps. Each step with the 50 step volume control is twice the previous one. So the only benefit would be the time saved in the mechanical pressing down of the accelerator. That can't be much. Could you gain .25 second? Maybe. Depends on the quickness of your foot. There is no question that you would get a more responsive accelerator per unit of depression. This may come at the expense of more wear on your tranny. That feel of the throttle response is part of the signiture feel of a Mercedes. You learn to be more aggressive with the gas pedal if you need to get moving. Regards. Ned.

Having driven M-B's for nearly four decades it has always been a characteristic of the breed that they are fitted with long travel non-linear throttle pedals.
From the 1980's they were also fitted with speed sensors so that the driving characteristics changed when you pushed the pedal faster and more aggressively.
It was my understanding that this characteristic gave precise control at low speed so that Dictators could move around (through) their subjects gracefully but folks who migrated from other brands found the throttle response felt tardy.
Since the advent of fly-by-wire throttles in the 1990's lag has been an added "bonus" and this was a noticeable characteristic of my M113 ML500 when moving off from rest - nothing, nothing, vroom.
I think my E550 is pretty good and if I want more grunt I do what I have always done - push the throttle hard and quick and if I want to drive quietly I have sublime control.
Does this accesory affect the cruise control characteristics? eg make it rough and jerky.
