The manual version outputs the 100% throttle signal earlier than the automatic version. I used to have the automatic version. I now have the A2 automatic version, which is even less aggressive.

He mentioned a version designed for AMG cars, less aggressive, this must be what you have.

It's interesting that the manny version is more aggressive,
wouldn't it be hard to shift and take off smoothly?
Sounds like a recipe for early clutch wear, and considering the fact that the C Class manny tranny isn't the strongest, a recipe for problems with the tranny.

Seems like it would almost be the opposite, more aggressive on the auto, less on the manny?
It would be cool if they had some diagrams showing the response curves of the 3 versions in relation to pedal position. Obviously they put some thought into it.

I might want to go with the A2 version as I don't really want much to happen in the 1st 10% of the throttle range, already a little touchy.
I can barely touch the pedal as it is when cruising or taking off in traffic.
Don't want to barely touch the pedal and rear end the guy in front of me.
Saw that the other day, a guy taking off from a light overdid the throttle,
bam, right into the car in front of him. I thought to myself, I wonder if that would happen to me if I got the SB?

How would you describe the difference between the 2 auto versions in terms of how the 2 actually actually react in the car, and why you went to the 2nd version?

Just wondering,if I buy a SB for non-AMG models,it'll fit any non-AMG Mercs from A-Class to....??!

TIA

im sorry one question and comment sprintboost what exactly does it do how much power how mutch torque and from what i hear that is a spring so your accelerator does not get stuck does it really lower your gear?

Midnight Koop

all your answers are in this thread... please read previous posts

Why more and more people selling their SBs?.

swapping out old ones for the new AMG-specific ones

If anyone wants a Sprint Booster for an auto-transmission I have one that was on my C230K SS for about a week, it gave my car too much power and I had to baby it to get my 32mpg. I paid $300 from Hong Kong, its only a few days old, if anyone wants it for $250, or best offer? Let me know. I'll keep it in my car until someone contacts me though it is fun, but I think I might put the money towards pulleys.

Thank you for the throttle information.

I have posted some other information on a U.K. site.

Below is a schematic of my first thoughts on the subject.

It is not a reverse engineered design, but someone may want to use it as a starting point to experiment.

I just read a whole thread about the sprint booster, I'm interested. But the posts were from last year and the Ebay link I got was no good.

Anyone know where I can get an AGGRESSIVE SPRINT BOOSTER???

Thanks!

SlvrC230SS

Come on, man. STF more. I found the link from forum like couple months ago.

derrickonline

ok ok...I found a guy who lives in MD and sold one...I PMd to see if he had more I could meet him in person to buy.

But all the other posts are old as far as wear to buy. I did search.

jmza2

this is the link from one of the threads http://www.slkfans.com/. I haven't contacted the myet so i'm not sure if the offer is still valid or not.

Hope it helps

I'm skeptical about purchasing from some random site that says basically nothing but..."hey buy your sprintbooster here, send me your money via paypal"....can anyone testify that this site is legit? Has anyone ordered from it?

Why not search for testimonials, if any, good or bad, on here?

You should scroll back up this page....hint hint...$220.

I know there's been a bit of discussion/feedback about these here, but I thought I'd throw in my 2 cents ...

Just got one, used - manual (aggresive) version, from someone who had it on their automatic like mine. Once you know what you're doing, install truly is ~ 5 minutes. Once it's in and you drive, whoa nelly!!! Yes, it makes quite a difference. Power is there instantaneously. So much so (maybe becasue I have the manual version) that I find myself having to pull back after taking off from stop signs because it takes off so quickly (almost like balking, if you will). All the 'perceived' pedal travel is moved up into a shorter throw of the accelerator pedal - If you floor it, there's not much, if any, difference than flooring it without the Sprint Booster. In fact, it actually seems quicker not to floor the pedal ...

On my first test drive, just getting used to it, a new SRT4 chased me down and pulled up to me at a stop sign. He revved and looked at me with a smile, so I took ESP off and went for it when he did (left it in 'D', sport mode) ... took him easily, but we only went up to ~45 or so. He was a crappy driver, I took him from the line and then really lept out ahead when he shifted from 1st to 2nd, but the off-line response is soooo much better with the SB. I'm not sure I could have done that without the SB ...

HOWEVER, I live in a small town, lots of potholes & dips in the road. For just cruising around, I'm not sure about it yet. If you slow down for a dip, go thru it, then try to give it just a little gas (even with a very sensitive/gentle right foot), the engine will want to rev up and you will almost always be dropping down a gear lower than without the SB. Same thing with going around corners, or slowing for potholes, etc. You can definitely get used to it, but forget about trying to drive 'economically' (i.e. like a grandma). I think mpg will invariably suffer.

I'm going to fill up today, and try it for a full tank of gas, then take it off and see how much I miss it. I'm also going to keep my eyes out for an automatic version and try that too. That might be a nicer comprimise between the throttle reset and this version SB. Cheers!

Thanks for the review! I'll definitely be getting one soon.

i'm still deciding to get one or not

After reading a ton about them it sounds pretty lame if you think about it logically. It does not give the car any more power, all it does is shorten the amount of pedal travel required to increase the throttle amount.

Instead of buying a sprint booster and losing the ability to lightly accelerate when you want to, just push the damn pedal 3/4 of the way down! Same as having a sprint booster, you just have to push the pedal further. This way when you want to get some decent gas millage you can accelerate slowly. With the sprint booster it becomes harder to do that.

Nice write-up mtnman82. Thanks...

Jay9722

I have to disagree with you on that point. The difference is like night and day. Pushing the pedal 3/4 down does imitate what the SB does, not in the least bit. And it isn't always a balking, herky-jerky, drive. It can be civilized until you really push the pedal quickly. I took mine out just to see the difference and it was big. Yes, it is just tricking the potentiometer but still...that quick pedal response is so worth it. I would recommend it for everyone but definitely go with the non AMG version even if putting it into an AMG.
