"I was thinking about the purchase of this product for a long time. Finally convinced myself to spend the money to do so. It's not cheap, but it really does do what it claims. Great feeling, especially at the low end. Sure wish I'd done it sooner. "
Here are some Sprint Booster user comments posted in various forums:
"Gang, this thing really works and is worth the $ - even at near $400 that I paid... It will bring a smile to your face!!! Guaranteed! "
It def. makes a noticeable diff in the responsiveness of the throttle. For those of you that came from E46 m3's its comparable to pressing the sport button. Because of this it def helps with the laggy shifts at low rpms. For the feel that you get from this it IS worth the money. I am very satisfied with everything: the cost, the short time it took to get here, and the ease of installation!
I just installed the Sprint Booster in my R53 and I felt the difference immediately! Yes, it's expensive, but I hated the delayed response with the throttle and the Mini dealer couldn't fix it even with a flash firmware upgrade. So I was willing to pay for this booster. Anyone that hasn't tried, need not criticize it. Let me tell u that it works and the throttle response is very sensitive now. As soon as u step on the accelerator, it goes! No hesitation!
So tonight I installed the Sprint Booster. All I can say is, WOW! I am the most skeptical person when it comes to mods like this, but I have to admit that this mod is worth EVERY penny!!! For one, there is zero lag when taking off. You step on the accelerator and the car just takes off. When you drop it into 2nd, it pulls off again without any hesitation. The throttle response is just insane and it shifts very smoothly! The shifts from 3rd to 4th and beyond is fantastic as well! The car just wants to go, go go! If any of you have been considering this mod, DO IT! You will not be sorry. It's too bad BMW's don't come this way to begin with. Well, that about sums it up.
I just installed mine SB on Sunday and echo everything else said by C's Bimmer. The 2-3 minutes it takes to self-install this thing is well worth it. As far as fuel consumption goes, it might be using a touch more but I think the biggest contributing factor is the temptation to let it all hang out. Now I definetly need a V1!!! Acceleration is definetly improved, not sure what that would translate to in 0-60 but you'll notice it trust me! Don't delay... Get one today!!!
Good for you for giving it a try. We installed one in my buddy's MINI (15% + CAI only) and the difference was amazing. Pulling away from a light was much better and the top end felt the same. I understand how it works and no, moving the seat closer doesn't do the same thing. I tried that before we installed it. When you move the seat closer your foot is now at a jacked up angle and makes the car harder to drive. The SB just made the car funner to drive. It "feels" like the car has more power. I know it doesn't but you sure think it did. I agree that people shouldn't judge until they try it. It does take some getting used to but I would recommend to anyone to give it a try.
I installed it in less than 5 minutes and I have to tell the skeptics that YOU ABSOLUTELY DO NOTICE IT IMMEDIATELY. Crisp immediate throttle response from idle all the way to the red line. Those of you that have the SMG can get a feel of what the SB would do by driving your car in non-sport mode and then pushing the "sport" button and noticing how much the throttle response is improved. Well the SB improves the throttle response over the "sport" mode in a similar way. It's like having another "more aggressive" sport mode that has even faster throttle response. The only difference is that sport mode also improves shift speed and SB doesn't, but as ECF said because of the immediate throttle response it "seems" like shift speed is also improved.
Hey guys, I'm back for a bit, just visiting. Sprint Booster is great!! I can confirm that along with all the great stories already on here. When I posted about it a few months back, a lot of people were skeptical about this, but now there's so many of us using it. On the E60, it was insane, I currently have it on my CLK, it really improves the car A LOT!! What I do notice tho, and if you guys care to discuss this, if you put the car on Sports mode (DS) do you guys feel like the car shifts abruptly somtimes? Like its hard to drive smooth with this thing, but its damn fun to drive likt you stole it. If any of you guys hvae both an MB and a BMW, try to get it for both, I think the MB shifts much smoother with the SB installed than the BMW, maybe its because of my driving style, but still recommend it to ANYONE!!
I have had the sprint booster on for a few weeks now and even though I was skeptical of how much of an improvement it would make I must say I am very happy with it. I have a modded mini with a Thumper head and custom tune along with a few other bits, and it definately makes driving a whole lot more fun. Was it worth the money...yes (considering my wife spends more on shoes each month....). It does take a little while to get use to but now I wouldn't take it off. After the head it was the best mod I have added. Also it was the easiest mod I have added only took 30 seconds! A monkey could probably do it in 15...
...so had a SB installed on friday, after buying it from a local shop here in austria. my feedback: wow. everything the guys claim here is true. you do notice it, and unlike other forum members here, my g/f tried it out and she noticed immediately - considering it for her golf now
I just installed the SB, it took less than 10 minutes. I was trying to find a way to hide the wire but decided to leave it out as is. After I went for a quick test drive, all I can say is "If you don't have one, what are you waiting for?" BTW, this is my 1st mod ever to the E60. This mod is so easy and simple, you see the improvement instantly. Highly recommended.
I want to share my experience with the Sprintbooster. First, I've got to say that this is definitely a good mod if you're a performance enthusiast. As the others have mentioned, the car feels more 'alive' and also far more sporty. The sprintbooster basically reduces the lag from the ECT by multiplying a certain amount you press on the gas pedal. So say before installing SB you have to press the pedal half way down to get your RPM jumping high to around 3-4k RPM. Now you only need to press it 1/4 down to get your RPM to the same point.
Put mine on last night before the wife and I went out to dinner. All I can say is Wow! Throttle response is awesome. I was skeptical, but now am a believer.
Having done 100 miles or so since installing it this morning, I can say the biggest improvement is from around 20/30mph. You just nudge the accelerator and get pushed back - much more than previously. I like the effect and will be keeping it. As noted above, effects will be more obvious without a remap, but I would recommend that everybody gets one. It's (relatively) cheap and if you don't have one, we all do, so we are better than you, nur. I certainly don't regret getting it.
Oh man no way, I completely agree with C's experiences since I finally had a chance to taste what the SB hype was all about. All I can say is holy xxxx xxxx!, my car is seriously out of control with the SB installed. I drove around with it on for a day and became instantly addicted like a crackhead, I then removed it the next day to see what the difference would be and I hated driving it! I don't think it's about being an extra 10% more responsive, it feels like a whole new system of throttling. Besides the instantaneous throttle response, the shifting is much much quicker, feels stronger and better. My first gear pull is constantly peeling out now, the freeway pulls feel much stronger, it's like a whole new gearing took over now. You have to try it to believe it. Bottom line, WELL worth the price.
My friend just installed this on his 2005 545 and he loved it. The throttle response is greatly improved. He is about to get a software remap so he's also going to test the Sprint Booster after the remap.
I LOVE IT! The throttle is much much more responsive. You actually have to get used to it a bit and feather the throttle or the car will surge. The responsiveness in P400 mode is closer to P500 mode now. I know there's no incremental power improvement here but it just feels like I added about 50 horses. The car is noticeably quicker off the line and lunches stronger with each gear change. Now the downside....I have to give this thing back to my friend. =(
A couple of weeks go I went to xxxx Porsche, The sales rep suggested I try the boxter S that was fitted with one of these devices. While I was skeptical, I tried it anyway. Woooow, felt like another 30-50 horses strapped on.
I had them installed on my 2.7 at the spot (took them less than 5 minutes to install!). After the install, I drove back and force around the parking lot and it was a night and day difference! After the test drive, the staff asked me if I wanted to keep it or take it off. Since they were having a special pricing, I decided to keep it. Throttle response definitely improved. The car pulls harder as RPM climbs up much quicker. Passing slower cars on the highway is much easier as well.
Ok people...got it installed this afternoon. First impressions....I really like it! The car is alot more fun to drive. Can't tell you if the car would be any faster in 0 to 60 or the 1/4 mile but it feels alot more responsive especially at low speeds. It gives you the impression that would have more power. The throttle response is much quicker and i like it better than the stock way. For those worried that it would be too hard to drive in daily traffic....well it is not an issue...it's not like you're at WOT just when you touch the pedal. The install took about 2 minutes....you pop the hood...lift the plastic cover at the top.....take off one plug....put in the sprint booster in the plug and attached it back. The salesperson at the dealership had it for a while in his car and he loves it also. He told me that i would feel a difference right away but that it would be even more as the ECU adjust to it in the next few days. It's the kind of product that makes your car a little more fun to drive....sort of like the rear sway bar. So personally, i like this mod so far....i have spent $$ way worse than purchasing this device!
I always wonder why on forums people knock the Sprintbooster but have NEVER tried one. Ive never seen a second hand one for sale..
We have installed it in a 2000 MK4 Golf 1.8t manual and have notices HUGE gains. Much more responsive off the line & in every shift and great for double clutching.
I just had this put in my 07 A4 and all I can say is WOW! It took me a couple of blocks to get the sesitivity worked out but after that its awsome. First, second and third gears feel like they pull alot harder, way more repsonsive 4,5 and 6 are more responsive as well. They aren't kidding when they say this reduces response time. You go through the gears faster and the engine really responds crisply and it feels like you have more power unleashed. If you any other performance mods you have to get this. I think it compliments everything else.
Got mine today. First of all, a technical disclaimer. I know it doesn't add horse-power. That it's just removing the adaptation/non-linearity of the pedal range. Basically, it feels like a completely different car. It's hard to describe, but the basic feeling is that the power is in your foot - like you have authority. It was really easy to install, but a bit freaky the way the whole pedal assembly just kind of falls out, but it's easy to get back together. I have to check mine out again because when I turn the wheel lock to lock, something in there is taping/touching the extra cable. Have to do something with that - any tricks/suggestions, or just let it hang in there and hope it's all good? Anyways, best mod yet, took less than 10 minutes, used a 10mm socket on the nut and a screwdriver to pop off the nut-cover. The car just feels farking FAST. Like I expected it to be when I first got it. Feels like a big V8 in there. A lot more controllable. You WILL notice a difference and if you always felt like you were waiting for this car to go fast, you WILL like it. It's more like it wants to go, and you're just holding it back - it feels like a fast car. THIS is what I always wanted this car to be.
I too installed this mod yesterday at lunch. The install took about ten minutes, but I was a little concerned when the pedal assembly did not come out as easy as I thought, and getting it back in was a little tricky, but with in the ten minutes,, it was done. I like this booster very much, the car is responsive, but still controllable (you will need to feather the throttle more than before). I still have not had the opportunity to really open her up (to much traffic), but I hope to do this today. Other notes: After a 3/4 push on the accelerator, the car moves very quick, but when backing off the gas, the car is still accelerating faster than before. I also put the tranny in the "W" mode and it seemed to mellow out the sprint booster..............
Just installed my Sprint Booster, and i'm very pleased with the results. Took me a little more than 10 minutes to install it, and yeah I agree with you guys that it is a little scary that the whole accelerator just kind of falls out. My car feels A LOT more responsive when i touch the throttle now. Well worth the $$ i spent.
Y'all - I installed mine in less than 10 minutes today. Money well spent! The car really lurches forward when you touch the accelerator. It seems to me that the supercharger kicks in a little sooner also (although maybe I'm imagining this). Great product! - be careful when you first put it in though - it's pretty aggressive especially when in traffic!
the car does seem faster even if it isn't. For people who say pressing the pedal harder would give the same results, well i would have to disagree
its hard to describe but I would have to say the car just feels more willing than before the reaction time is much quicker and even small inputs on the throttle seem to gain a response where as before I would just get nothing, nothing then bam! Overall well worth the money and highly recommended.
Just put in a sprintbooster. Easy to do except for the recalcitrant clip, otherwise obvious. It's pretty hilarious, I have to say. Instant response like my 740i sport but brutal. Revs don't seem to climb on the gauge any differently but response is there. It's beyond the question of whose butt dyno is more sensitive than another's I'm sure. I dropped it off my foreign car place for an oil change and he took it around the block with me and he said "it's very responsive". It's a rewarding $$ spent. Rolling burnout with ESP off at 15-20 mph. I'll post again if things change. Update: I just picked up the car and the tech asked me "what did you do to the throttle" and I told him he just shook his head. I have to say I think this must improve 0-60 times but I have no data to support this belief
installed it last night. there is a noticeable difference in throttle response, especially from a standstill. from a stop, i almost lost my grip on the steering wheel from the quicker acceleration from being pushed back. i would recommand this product to others (easy install, cheap, noticealbe improvement in throttle response).
I installed this gadget "sprint booster" a module that is made in europe on my SLK 200 (M271) and my vehicle is behaving a monster. The throttle response is unbelievable when it comes to acceleration. It is just like having a well tune ECU in your vehicle. Some fellows have installed this module in their C32 AMG and C55 AMG and the response is amazing..
Thanks for a great product. The car should've come like this stock, or at least been like this in S and M mode, but been subdued in Comfort mode. It is very manageable to drive, it's very fun to drive, it totally fixes the car... I should've done this 3 years ago. Before the car used to feel like it had a turbo on it, with a too large A/R and too small a compressor housing... you wait and you wait , then boost comes on, but there isn't that huge surge of power that you expect after that much lag. Now the car feels properly supercharged with a centrifugal blower...
Before I would go into boost at about 70% throttle. Now It boost at about 40% throttle , which is typically as deep as most people go for a typical highway pass.... much more linear performance and I likes it...
I've had my SprintBooster on for like 2-3 months now, and I can say that I'm pretty happy with it. The response time is a lot better and the car does seem faster
