That may be difficult this close to Race Wars. Perhaps they can be overnighted from Japan?

 

I'll throw my .02 cents in. I think even $100 for this is rape. Maybe $25-35 tops, IMO. I can see the benifit as previously mentioned, when using NOS, but that's it. I mean, even drag racing, how long does it take to make your foot travel 1/4 pedal to full throttle...assuming you launch at full throttle (some don't)?
For those who indicate some delay in throttle response stock....I've got 120k on my car, recently purchased and still doing "tune up" things....this car has never had any delay in throttle response as compared to my 3rd gen or other CABLE driven vehicle. Any lack of "instantanious power" I've felt out of my 2003 was resolved with new NGK Iriduims. I just stand by what has been posted, SO much more could be done to the Maxima with $300 that would truly add power and performance.

Still interested in hearing further experiences.

 

Well I know for drag racing on street tires, you need precise 50-90% throttle control and I think this would make that more difficult. I also have no lag at all with my throttle input. It feels like a cable driven.

 

I'm not convinced the analogy is off. Both mods are reducing the physical travel of the driver's input, which is the source of the change.

If this booster thing alters the way I connect to the car, and it does it in a positive way, I could see the value in that. Not $300 worth... maybe $100. That's my threshold for this thing.

 

From your perspective, they can be considered analogous, but then every modification would also be analogous; changing an operator's interaction with the vehicle.

To more finely differentiating products the methods of change should be accounted, and are quite different. The short throw shifter changes a physical linkage, while the sprint booster alters the pedal position sensor's correlation of position and output voltage. Since the sprint booster does not make physical alterations the pedal travel remains the same whereas the STS will change throw distance. The sprint booster manipulates control output to 'fake' greater pedal applications which also creates high and low sensitivity pedal position areas.

If I have time later I will generate a curve of what I believe the sprint booster does the pedal position sensor output.

 

No, only those mods that interact with the driver are analogous. Engine mods like intake and exhaust, they don't apply. But brakes, suspension, steering, transmission, and throttle all do.

The fact that a STS is 100% mechanical, whereas this booster thing is electronic, is irrelevant; because the effect of the booster translates into a mechanical action.

Don't get me wrong... I'm not interested enough to gamble $300. But I have to admit that this is more interesting to me than it was originally.

 

One mod that will make your N/A auto feel faster than this is to go with lower gearing (ie small wheels/tires). Get some 16" or 17" front wheels and go with 235 or 245 width with 35 sidewalls. That would be about 1" shorter than stock for 5th gens.

 

I think a lot of people have misconceptions about what the sprint booster is for. It's not going to improve your quarter mile times, it is not going to make your car go faster. All it does is eliminate throttle lag. some of us have it, some of us don't. This is for those times when you are behind an 18 wheeler cruising at 45mph and you want to pass the 18 wheeler. In most of the maxima's I have been in, if you floor the pedal there is a delay before the car recognizes you matted the pedal. So if you want to pass the truck you have a slight delay and then the car surges forward. Not so with the sprint booster.

If you want to eliminate throttle lag, the sprint booster works. If you want more horsepower or want your car to go faster, buy something else.

 

Not to be petty or argumentative, but any modification (if effective) has some interaction with the driver. In another thread you mentioned that with the NWP intake spacers you had to adjust your driving style; increase engine speed at constant vehicle speeds due to power loss. This is a modification with an affect that changes the driver's interation (behavior). Also, the accelerator pedal/throttle is part of the engine (control system).

If modifications are compared based upon the impacts to the driver-car interaction then everything is analogous. Rather, modifications should be categorized more finely before comparisons are drawn. Wether this is by function (e.g. power increase) or by method (e.g. mechanical, electrical, chemical, etc.). In this case, a STS can impact quarter mile times, but the sprint booster cannot; using different methods.

 

There is no misconception within this thread. The participants realize this device solely changes the correlation of accelerator pedal position to pedal sensor output which invokes the response of a greater pedal position; the mythical removal of 'lag'.

In your acceleration example, the sprint booster just 'floors' it (reaches position sensor full voltage) quicker.

Changing the x-axis on the chart from the sprint booster site the differences in correlation can be observed. The chart also exhibits the problems areas I mentioned in a prior post.

 

My NWP Block Plate took my hesitation away. Before I installed the plate, hesitation was really bad for some reason.

It would be nice to 'feel' faster, but for $300? No way. Ill just drive my 97 for a few days and the 03 feels way better!!

 

The hesitation was likely the result of heat soak for which the spacers can minimize. Not to put words in Rochester's mouth, but his comments seemed to indicate a power loss rather than hesitation (even though power loss can be felt as hesitation).

 

When I had the spacers installed, it did feel like the throttle became more responsive, so those words fit in my mouth just fine. I'm not sure if those are the same words you were alluding to, but there it is anyway.

No worries, man. I love reading your stuff. In fact, as I reconsider what you wrote here, I find myself agreeing now that any change in the car impacts the interaction between driver and machine. Well said, 2slow.

Still not spending 3 bills on this gadget, no matter how interesting it is.

[edit] And the graph explains things well. Maybe not in the way the booster people intend. (I see booster people...)

 

It's not bull****, as I said try one out, if you like it buy it, if not have them take it out, go home and have a beer.

A few of these got the sprint booster through me. I guess they are lucky though since I can "borrow" the tester from my parts guy and they can try it out on their car before buying. No one who has tested it on a g35 refused to buy it. All the maxima guys who have tried it want one but they agree the price is a little steep. I guess the guys who drives G's have a little more cash than maxima owners.

 

This is such a stupid mod I'm sorry. Just put the pedal down more and you get the same effect. This probably ruins your mileage as well considering this stupid thing is just applying more throttle per push.
Any sort of effect this thing can do I can do by applying more throttle pressure, thus the only people who need this are lazy or simply are bad enough drivers that they don't know their own car well enough.

Learn your car, save your cash. Never pay for something you can do yourself, and especially in this case when you can so easily. Put that $300 towards some real performance parts if thats what you are going for.

What a scam of a product.

 

I can just drive my buddy's RX8 and my '01 feels like a rocket

 

What's really stupid, is there are literally thousands of people on the forums driving all the high end cars who think this is the best invention since sliced bread, but all you guys have your head in the sand thinking it is a complete waste of time.

 

So because someone has a high end car, they know about cars? I bet if they understood cars beyond a caveman's education they'd realize how much of a rip off this is. We all know you're only defending it because you benefit from selling them, end of story. Its a scam.

 

Maybe the better analogy regarding perception and the driving experience, is the manual shift mode on the 7th gen CVT.

 

Someone with a higher end car is more likely to better afford $300 on this gadgetry, so it's all relative.

I don't for a minute think Knight's endorsement is anything other than genuine. C'mon, that doesn't connect.

 

It actually makes perfect sense, why would he bad mouth a product he pushes? If there is money involved people will endorse garbage all the time.

 

Money cannot buy intelligence or taste. It can buy parts which you were told, and believe, makes a vehicle more responsive without a real understanding. Your comment is social Darwinism at it's finest.

Just because common knowledge is 'common' does not mean it is correct.

Or just about any auto-manual's manual controls; excluding the automatic manuals: DSG, SMG, etc. It may feel different, but isn't better or faster.

 

All I know is what I've read over the last year, which leads me to think Knight is always sincere. If that were your baseline, rather than avarice, you'd probably come to a different conclusion.

However you look at it, I'm starting to get confused. Having one of those, what-are-we-talking-about moments.

 

Well this statement is not entirely true, as I benefit nothing from endorsing the product, to me and the few test runs I got to do, it simply delivers what it said it would. I also stated that at the time my dollars were tight and did not purchase one but did say I would consider a purchase of the product in the future.

You have your opinion of the product as I have mine, so I don't believe slandering another persons opinion is relevant or accusing another persons opinion is bias because you feel they are profiting from there statements as I stated my benefit from endorsement yields me nothing. The purpose of a discussion is to get all view points of the items merit, yours are valid from your prospective as are those from others that have personally tried the product. Like all products offered on the market there will be pros & cons. Offering slanderous comments towards another individual has no place in a open dialog/discussion. (shame on you)

 

Where did I bash Knight? I'm bashing the product. Saying hes endorsing it because of money isnt bashing, its expected and I never put him down for doing so.
Shame on you for not being to comprehend how useless this product is and for accusing me of something I didn't do.

 

There are three issues with these arguments; not that I know all.

First, a conflict of interest should always be noted. In this case, the main proponents have a vested interest in positive reviews. I am not stating the individuals in question are dishonest, but some are and it is worth noting for the sake of the consumer.

Second, many opinions are being stated as facts and potential consumers must then decipher fact from opinion. This is always difficult to deal with for products which solely generate anecdotal evidence; there is no experimental data to gather, only feelings.

Third, contrary opinions ("don't buy this piece of crap", "the seller will always give positive reviews") shouldn't assumed be slanderous. These comments have value telling others the writer's opinion, just as the proponent tells of his/her opinion ("smarter people than you believe in it").

*all quotes are paraphrased.

Edit: I'm a senior member, hahaha

 

When arguing a point, it's always difficult differentiating between the discussion and the people involved. Being able to do that is one measure of maturity.

So I'm done. Let's see if this ends well.

 

Well personally I've realized the folly of my testimony. I will be ordering 2 and installing them in series for a double increase in my throttle responsiveness.

 

To me when you make the statement he pushes, and then follow it up with making of money, that is slanderous as knight_yyz has already stated he makes a walloping 10 bucks, so there is no hidden agenda for making huge dollar amounts. As well as I don't see where he is pushing anything, by letting others know he can also get the item for them.

I value your opinion that to you the product is garbage enough said, but there are some of us that can see some of its benefits.

I have said my piece, so back to the topic at hand.

 

He said himself that selling them gets him discounts on other products, even if he doesn't get a direct profit. That doesn't necessarily mean he would have an agenda, but makes it more likely.

I would like to see people who have this installed on their daily driver give an honest before and after gas mileage comparison for city driving. That "increased throttle response" is just more throttle being applied and should be pretty noticeable. The problem is that the likelihood of someone who has spent ~$300 on one of these admitting that it's just a placebo effect which could just as easily be caused by putting your foot in the gas more without one installed is pretty low.

 

Couldn't have said it better myself, so I won't. And to close my thoughts on this Ghost, please list these benefits you speak of, besides Sparks Nitrous application.

 

Stay on topic dudes

 

I didn't really have a hesitation, just a sort of soggy response to initial throttle inputs. With the block plate, the throttle response is noticably sharper, especially at part throttle.

 

I knew it wasnt all in my head.

 

I don't see how this would have any effect on gas mileage.

This has nothing to do with the efficiency of the motor, just the correlation between the accelerator pedal and the throttle butterfly.

Say for example that the throttle butterfly has to be open 16% to cruise at a steady speed of 60mph;

On a Maxima without this device, we can say that the accelerator pedal would have to be pressed in 16%.

On a Maxima with the device, the throttle may only have to be pushed in 10%.

Either way, the throttle butterfly is open 16%, and this is what determines how much gas is used.

And acceleration is modulated by the human. It may take some time to get used to the new throttle "sensitivity," but after a while, the driver will adjust to the pedal feel and drive with their normal acceleration. This will only make the car feel like it accelerates faster when it is first installed because after a while, the driver will learn around it.

Sort of like when you drive a friend's car; at first it feels different but after a while you'll notice that you get used to it and you actually end up accelerating at about the same speed as you would when you drive your car (with the car's limitations permitting).

 

Go on the BMW forum and read, go on the porsche cayenne forum and read, go on the audi forum and read, go on the g35 forum and read. Go on the mercedes forum and read. Or shall I spoon feed you?

With all my mods including the sprint booster I get 8.4 litres per 100km, which translates to 28 mpg, which is pretty damn good in my opinion for a car with 250whp. My mileage did not change at all because putting a sprint booster on the car did not force me to go over the speed limit.


And anyone who thinks I am making any money or saving thousands of dollars at a high performance car parts place is fooling himself. I already have full bolt ons, so what else do you think I can buy for my maxima? Absolutely nothing. Maybe, I will save an extra 100 bucks on a set of coilovers. For selling 30 sprint boosters? It costs me 10 bucks in gas to go there and pick one up, it isn't like this place is around the corner from me. I endorse the product because I have tried it and it works. And anyone who has not tried it and thinks it is bull**** needs to take his head out of the sand and try it for themselves before bashing it.


Warning, spoon feed coming up.... this is the link to an article written by the OWNER of the porsche cayman club...

http://www.planet-9.com/reviews/show...duct=246&cat=4

Note there are hundreds of articles like this if you SEARCH.


OH, and the reason the OP couldn't find anything on the org about the sprint booster is the org search function is uckfayed and doesn't work. Google works fine for those who really are interested in the product.

 

Wow. Seriously, wow. Infomercial time!

Ok, look. We all know that it increases the TPS signal. Nobody in this thread is disputing that. OF COURSE it "works" and you can "feel a difference" when your gas pedal only needs 80% of it's current throw to go full throttle and becomes much more sensitive to input. But that is ALL that it does.

Take one of those people who has just installed a sprint booster and tell them to drive like they normally would have before, and yes they will get a reduction in gas mileage because of this device giving far more throttle input than they would expect with their "stock" gas pedal.

Sure, you can adjust to it and drive like you always have, but then what's the point of having it? You can make your car perform exactly the same as it does with the sprint booster by pressing the gas pedal further down. It's as simple as that.

That is the reason I'm calling it a joke. 300 dollars to make your gas pedal shorter and less capable of modulation so that you can (falsely) feel that your car is now more responsive and faster.

 

Here's some porche owners telling us how totally sweet the sprint booster is:

"Scary set-up for track with my experience level. Overly sensitive throttle in certain tracks I run will be nerve-racking plus the added learning curve for heel and toe during threshold braking"

"after all if that device just modifies the pedal signal, it means, in stock form, that it will have the same effect if you just push the pedal all the way"

Oh and here's some people advertising about how the sprint booster totally made their porche faster... what a joke:

“It will give you a similar experience to sport mode or a ECU tune but for less money than either a full ECU tune or ordering sport chrono from the factory.”

"My overall impression is that my car does accelerate faster, it screams louder and sounds more "raw" and it races through the revs"

Man, those Porche owners have got it right. I really need to buy a sprint booster now.

 

No it isn't. If you have throttle lag, punching the gas pedal to the floor will not get rid of throttle lag. You will still have throttle lag.

If you install a sprint booster the throttle lag will go away.

 

Dang I should have got this instead of a UTEC
