Some insight 5.5ers??

 

I saw the same thing the other day. I searched on the org, but didn't find much.

 

Its not for cable driven Vehicles like yours, Its for Electronic TB's


But its an interesting concept...

 

Is there something in the listing you don't understand?....they seem to answer just about every imaginable question, including installation.

 

Im asking for insight by Orgers, not what the Manufacturer claims bud.


Also found this, Seems to be heaven for the G35

So it's for my 5.5 gen..

 

oops

I looked at your sig MAhh Bad.

 

It happens..

Anyway, I'm just wondering if anyone else has installed this and if it actually works? It would be a nice little upgrade for us auto owners.

 

Same here.

 

Why only auto owners? It lists both:

02-03 NISSAN MAXIMA Manual All Gas Engines
02-03 NISSAN MAXIMA Automatic All Gas Engines

Also, it says "money back guarantee", so if you believe that, you're good to go.

Feels like snake oil, though.

 

I'm not saying that it won't work on both MT and AT, it's just that there's more throttle lag with autos.

 

I did a little research on these when I saw something about it a few months ago. It appears that it just increases the TPS signal... meaning if you put the pedal 20% down, this thing will make your ECU think you're putting in 25-30% throttle. It gives the false impression that your pedal is now more responsive!

Basically, gimmick junk.

 

What a shame..

 

Interesting. I'd like to test this out at some point. Maybe help with the e-throttle hesistation.

 

Good call, Sparks. I've been banging Teh Google for the last few minutes, and came away with the same assessment. It "works" in the sense that it's messing with your perception. But once that change becomes the new normal, you're still not driving any faster than you were before.

I also read where MT owners have a difficult time dealing with the change. (MT owners... we're a sensitive crowd of old school drivers anyway.)

 

Spend your money on one, you will feel a difference... just not in throttle response speed.

 

Right. The Sprint Booster serves zero purpose in actually increasing horsepower, because it jacks with your throttle signals. Thats all it was made to do, I don't really think it's a gimmick persay, just because they're not making any false claims here.


According to this all it lets you do is just get into the WOT range quicker. BFD for cable guys, but the drive by wire guys might appreciate it.

However, $300 is way, way too much for that.

 

They claim faster throttle response, which is not true. They also claim increased throttle response, which is true. It literally just increases the TPS voltage signal. Shown in that diagram, your foot at 3/4 throttle = full throttle with this installed. So basically, the signal isn't sent faster, it is just inflated. I know for sure I don't want something that decreases my ability to modulate the gas pedal.

The only way I could see this being useful is when you have a mechanical WOT switch below your gas pedal to activate nitrous. With the booster installed, you would already be at 100% throttle when your foot is 3/4 of the way down, then you could push it the rest of the way down to activate your wot switch when you want to spray nitrous.

 

I have one on my car, I was the tester for the Maxima for North America. We first tried the 350Z/G35 version but the wires were crossed and there was no throttle. I checked the FSM's and sent the data to the main distributor for Sprint Booster USA. A few weeks later they had both ready for the maxima.

I installed the Auto version on about 5 cars, and the MT version on 5 cars and got reactions from all the people who tried it. I have sold about 25 or 30 with my jobber discount in the local car clubs in the Toronto region. I have had no complaints about this product. Your car will have better throttle response. Some people with autos reported crisper shifts. The 6MT version is more aggressive than the auto version.

If you heel toe this is a great product, you don't have to move your foot as much to rev match etc...

If you disbelieve, check the porsche cayenne website, the bmw websites and the audi websites and the mercedes websites.


BTY I have a slightly used one for 215 shipped for an AUTO.

 

Wow. Endorsement and personal experience from Knight_yyz. I didn't see that one coming.

Plato said, "Science is nothing but perception."

 

Pretty funny stuff... I'm sure Knight_yyz knows that it just boosts the TPS voltage (you could probably do this for 10 bucks with a small transformer), but getting money put in your pocket goes a long way.

 

That would make sense, tricks the TCM into allow higher line pressure at part throttle.

 

i have it on my 5.5 gen all it does is give u a better throttle response i like it though in 6th gear i can hit it and it goes

 

I've used one with a Chrysler Crossfire, and it does exactly what was previously stated; increases pedal position sensor feedback to increase the throttle position.

While it 'took-up' the lag quite well, it caused other driveability issues for which it was removed and now resides on a shelf. It made small throttle applications, or variations of, very sensitive which affected ability to smoothly start the vehicle and modulate part throttle applications (greater than 50%). These experiences caused us to remove the sprint booster, which made the vehicle much easier to drive (auto-cross).

I don't think there is enough throttle lag in the VQ to warrant this, especially for the price.

More street cred:

 

Such skepticism, it does what is says it will do. I drive an automatic and those of us that do, have experienced when you apply the throttle there is that momentary lag (perhaps 1/4 to 1/2 a second) before the drive kicks in, and when cruising and one applies more throttle to pass another vehicle, again one feels that slight hesitation before the the throttle engages. I was fortunate over a year ago to get to test one for a few spins and off the line the pedal does have a faster throttle response, and while cursing and applying more throttle the lag is no longer there so is does deliver increased throttle response. All in all a nice little mod the car was quicker to react off the line and more responsive while cruising as well the automatic transmission was shifting very crisp.

So one would ask did I buy one? well the asking price was a bit rich for me at the time (unfortunately), so no I did not.

Would I consider buying one? Yes, because it delivers what it says it will.

 

I spoke to Steve at the PRI show in Florida , I belive they have to re-write the program for the 6th gen. He said he would send me one when its completed.

Seems like a good try

 

Responses from people who have shelled out 300 dollars for this just reinforce the point. It increases TPS voltage, plain and simple. There is nothing revolutionary about that, and you could have spent far less to get the same effect. Or you could spend none and just push your foot down further for the exact same effect.

In terms of the auto transmission... press the throttle down more and it downshifts faster. With the booster increasing your throttle voltage, you don't have to press the gas down as far to get that quicker downshift. I guess that gives the impression that it increased responsiveness.

"It made small throttle applications, or variations of, very sensitive which affected ability to smoothly start the vehicle and modulate part throttle applications (greater than 50%). These experiences caused us to remove the sprint booster, which made the vehicle much easier to drive (auto-cross)."

That's exactly what you would expect... I suppose to the average driver it makes you think your car is faster because you get the same throttle with less pedal movement.

 

Since many consumers have automatic transmissions the driveability differences are hidden. Consequently, they experience the faster downshifts, less 'transmission lag', due to greater torque demand (pedal feedback).

 

They could get the same effect just pressing the pedal down more, that is all it's doing. lol.

It's a great idea to make a lot of money off of a cheap gimmick, though. The "omg I can tell a difference!" feedback attests to that. I wish I'd thought of it

 

Exactly, and at $300 a piece the margins must be great.

 

I guess I could see this being beneficial if I had an auto, but for the manuals I think it's nuts. $300 for something that puts the throttle at a point roughly 25% beyond what you think it's at? Um, why not just floor it yourself and spend the $300 on a night out on the town with your girl?

 

OR parts that gain you real horsepower

 

Yes, they have the proper connector, (the 6th gen gas pedal is the same as a few other cars.) They just haven't got around to making the electronics for inside of it yet. Problem is the Company is UK based so they have been making them for cars that are over there. Bimmers, merc's and audi's

Another way of looking at the sprint booster is like having a sport mode on the car.

For those who are skeptical. You can try a sprint booster for free. Just go online to sprintboosterusa.com and find the dealer nearest you. The install takes less than 5 minutes, take your car out for a spin. When you get back ask them to take it out of your car.

 

As I've said I have sold about 30 of these in the local car clubs. I get a whopping 10 bucks profit out of them to pay for my gas to go and buy them. All it really does for me is give me better standing at the shop I buy them from so that maybe I can get an extra couple bucks off things i buy for my car. So another 100 to sell and I can afford to buy my coilovers... LOL.

I get a discount on the sprint booster which I pass along to those who have contacted me.

 

Well I'm going to need 2 of them. The big ones.

 

I will take a couple as well...

 

im gonna have to go ahead and say **** this product

 

Reading through this stuff again this morning, I'm wondering if this is analogous to having a short-throw shifter?

Because my perception is that I'm shifting much faster than otherwise. Is that perception or reality? And if it's not real, then so what, as long as it feels better.

 

I don't think they are completely analogous. A short throw shifter makes a physical change which has real and perceived benefits (shorter throw distances and feel). The sprint booster alters the pedal position signal to create a perceived benefit (change in an individual's correlation of accelerator pedal application to throttle application; aka 'lag' removal).

 

and Knight_yyz... I need them by tonight.
