Why dont somebody just do some timed runs (standing start / rolling start) without the damn thing and then the exact same runs with the damn thing on?
Post the times here and then all will be clear.
Quit bitching FFS.

The sprint booster DOES NOT increase horsepower. Timed runs WILL NOT give you better timing.
For daily driving, it gives you better response. THATS ALL. Key word is BETTER RESPONSE.
Some like it, some dun. Some says good, some says no difference. Personal preference for each individual. No point arguing over one's preference.
This is especially more useful for those AT drivers, who are always in "D" mode. Those who play with tiptronic always, may not see much difference.

I agree with coupe07 as i have fixed one myself.
i feel that its mainly better response during gear 1 and 2 ....which can be a bit lagging at times for 4AT. Last time my right foot always felt abit sore over an hr or so of driving. But now, with the SB, i only have to deflect the pedal very lightly to get the acceleration i want. In all, my right foot feels less stressed.
BTW, one question: If i fixed up the final gear 4.777 with this SB, what will the scenario be like? even better response or....?
cheers

Guys, click these links and read on the comments from other peoples with other car models. http://forums.mbworld.org/forums/sho....php?p=1769593

Thanks to gfoo, his statment makes me check on the SB and finally find a way to solve the "lack of power" problem I have from stand still to go or overtaking instead of buying the supercharge or turbo. I shall have this installed by next week or so and i will also post my feeling about it later on. btw, im from hk and it cost appox US$320.00 w/installation from their dealer in HK.

bro.. dont get too worked up..i believe yr review becos ive heard fr various sources too. some americans (2fast 2furious types) are very cocky and have the 'know it all attitude', if u see their mods..they tend to go for the extreme approch even the japs wont go there, becos 'balance' is not in their vocab. they are the western equivilant of 'ah bengs' so let it be.. ill be getting SB soon, whats more i can try it before i buy.
guys, guys, this mod doesn't do anything to improve HP - nada, zilch, zip. What it does do is make the pedal that much more responsive - launches are quicker and it seems low end torque is better. my best 0-100 time is 9.5, i'll do another gtech run this weekend to see if anything has improved other than butt dyno.
Emperor, i dun really know how this thing works, and that's just my conjecture. i think what it does is increase the signal frequency to the ecu i.e. instead of say 1000instructions per sec, it's boosted up to 2000 ips. something like that. - i could be wrong.
My mods to date:
- RE Amemiya remapped ECU
- Autoexe catback exhaust
- Knight Sports metalit supercat
- RB Revi intake
- Knight sports 4.777 final drive
- assortment of cusco struts/towers/etc
- 8 point grounding linked to impedance stablizer and pivot
- assortment of defi gauges
- gtech
- scanman II canbus/CEL manager
- jdm autoexe front n rear bumpers; INGS sideskirts/spoiler
- Idemitsu rotary or RE Amemiya syn engine oil 30W
- Redline high-temp ATF
- Cusco LSD syn oil
I know a hack and BS when i see one, and on the surface this seems a little too good to be true, but it actually works. Whether you believe it or not, i don't really care coz i'm enjoying my improved low-end - to each his own dudes. Singapore bros (those that i know only hor, not every tomdicknharry), will let you try my ride the next meetup.
Disclaimer: i ain't selling this thing, am a customer that paid full price just like any other, neither do i own shares or have any vested interests with the retailer

I'm using TREC since day one. So may not know what is the different between original or with those electronic throttle control mod device on. I think the sprint booster is similar to trec. The theory can be found at http://www.siecle.co.jp/products/trec.html

anyone who thinks this increases power or torque in any way in any part of the power band is delusional .
All it does is bring full throttle in earlier on the pedal travel - making the car more difficult to drive ..... Maybe if you adjust your seat forward a bit so you can depress the pedal all the way down you would not need this crappy device .

gfoo,
murix' answer is about right. Drive by wire is like an electronic volume control. When you depress accelerator pedal the SB just changes the reading from say 3 into 6, 5 into 10 i.e. as though you pressed the pedal farther, faster.
I tried it couple years ago when MG brought it to the meetup. I was not impressed enough. I am quite fast and adaptive so I kind of quite quickly adjusted my pedal depression naturally and still drive the same way and speed I always did.
Mind DaveCM203's comment about the effect in the rain too. I didn't try that but I can imaging if you didn't naturally adjust your right foot strength you could buang in the wet !
So I told MG if it is much cheaper maybe I would have it to play with and when I tire of it or didn't need the effect I would take it out. Put it back if I want another temp thrill. Not worth spending $400. IMHO.

I'm sure glad you changed the title.
If you think this works try ssome pulse plugs.

I guess we hit a nerve!
You know, I was thinking about making one of these "Sprint-Boosters", but meant for the brake pedal. Instead of having to push the brake so hard to get maximum stopping power, this thing would just trigger the ABS/DSC to lock up all four wheels as soon as you tap the pedal.
That would be much better!

Bought the sprint booster but having trouble getting it installed. I unplugged the the clip coming off of the gas pedal. I had no problem connecting the SB to the end that goes to the engine but cannot get the end clip that connects to the gas pedal to click in. Maybe they send me the wrong part, but it's marked correctly, or maybe there is some trick to it.
I'm going to send it back for a refund unless any of you guys has any suggestions. Perhaps you had a similar issue?

Hi all. Just joined the forum not long ago and saw this interesting thread. I bought the sprint booster knowing its functions.
The technician emphasized on its inability to increase any horses or torque. No increased 0-100 timing. I bought it a year ago and the only difference i could feel was the responsiveness. Before installation, I needed to really depress the throttle to hit 7 1/2 rpm(Redline). After installation, I only needed to depress half.
Kindly comment if I'm wrong.
0-100 timing could be improved by the amount of time i save for depressing the second half of the accelerator.
If full throttle = 0.4seconds
half throttle = 0.2 seconds
0-100 timing improved by 0.2 seconds.(Est)

Put math aside, I can understand ur perspective of the improvements as negligible. But u have to agree with me that it will definitely take a shorter time to do a half throttle than a full throttle. Anyway my calculation is based upon reckless estimation.Pardon me on that.

Since a 'sprint' involves just changing gears and mashing the pedal-to-the-metal, I don't see where the time saving would occur. The throttle plate is electric, and I'm sure you can plant that pedal faster than it will flip open.
The biggest effect I could anticipate would be that when you ARE trying to use part throttle - to get a smooth start in first gear, you get instead immediate wheelspin off the line, losing those first valuable seconds.......
