Trust me. You NEED it. Youll out launch a z with out it. The response and power output comes in A LOT sooner to that of a z with out it. If you had it and I didn't. And we both hammered it. Your power would come in sooner then mine long story short.

, totally!!

This thing really does work and works well.

While going out for a night cruise last night, this blue 370Z pulled up next to me at a stoplight. We were on a four lane road and both first at the light right next to each other. We acknowledged each other then rolled down our windows. After pleasantries were exchanged, we agreed to go at it. There was no pedestrians present at the time and traffic was non existent.

I blew his doors off off the line. We got up to 70mph then slowed down. We pulled into a gas station and he immediately asked if I had FI. I laughed. We exchanged our mod list and found they were very similar. Both had CAI, CBE, with stock Cats. I said I have a Sprint Booster. He said he heard of them, but didn't really think it was worth the cost. After my performance that night, he advised he would immediately purchase one when he got home.

Okay lets keep this a secret. It for OUR own good.

Ok, I guess I don't understand how this thing works. The tables I've seen show it increasing the amount of throttle opening for a given pedal position, but WOT is still WOT, just occurring earlier than without the booster. If you were to simply floor the gas, the time spent at less than WOT is very small. I just don't see how it would make so much of a difference that someone could blow the doors off a similarly modded car.

Yes, it's snake oil. It quickens up the throttle by compressing its output.

Also, street racing posts are against the rules, so there's that.

It doesn't add power. All it does is shortens the response time and allows power output to come in SOONER then the stock OEM, similar to throttle by cable instead of our unfortunare throttle by wire. If we both would hammer it from a dead stop. My vehicle would throw out more power quicker and sooner at what ever percentage of downpress I have on my peddle then youes would even if we have the same % downpress applied to the peddle. Hence, I would out launch you through every gear.

You're correct if the gas pedal on both cars is pressed down at the same rate. From the other thread, there's a better explanation of what it does. http://peony888.com/VS/SprintBooster.pdf

I can see it having a noticeable difference in part throttle applications. My issue is when you say something like "if we both hammer it from a dead stop", implying you're just going WOT as fast as possible. How long does it take to go from 0% pedal to 100%? It's less than a second. That doesn't allow a great deal of time to out accelerate the other car. I get that the people who are using this swear by it. I'm just saying that the device is basically amplifying the signal from the pedal by about 30%. If the same hypothetical car next to you was pressing the pedal 30% more than you at the same time, response would be equal. Also, from the white paper, the throttle pedal will be sending the car a WOT signal at around 2/3 travel, so the pedal ends up feeling "dead" above that. Their words, not mine.

I think I might actually understand why sprintbooster "works".

Given that when the pedal is pressed to the floor immediately:

stock car's throttle map will not actually open the throttle 100% as soon as you floor the pedal because the factory tune gradually increase to 0-70-100% in about 1-2 second.(almost like spooling turbo) (for factory smooth power delivery, and driveability.) This is why you don't get that kick to the back of your head when you punch the throttle.

Now with sprint booster, although it does not enhance the throttle response or get rid of the lag, it does signal the throttle to open fully 100% as soon as you hit the floor to the ground. almost like on/off switch.

This is perhaps why it feels the power comes alive, because throttle opens up as much as/ or more than you depress at that instant.

Right, according to the white paper it tells the throttle to open about 30% more than it normally would given the same amount of pedal pressure.

Trust me, youd be surprised what 30% can do. I would let you drive mine if you lived near me. Acceleration, response, everything is quicker and faster. You don't get that lag response you do with the oem throttle setting. If you think there's no lag, you're in for a hell of a surprise with this on!!

You are just about correct with your understanding. The only comment I would correct you on is regarding the throttle response and lag. Sprint Booster does eliminate them both.

That is why when two comparable cars with similar mods go at it, the car with Sprint Booster will be faster off the line due to zero lag. It screams out of first gear. It really is awesome.

What he said!!

The time I purchased my Sprint Booster, it came with a 30 day money back guarantee. I too was skeptical at first, but I figured I had nothing to lose with the guarantee. Once I installed it, drove it, learned the difference with the two booster settings, I was hooked. There was no way this thing was going back.

Not sure if the 30 day money back guarantee is still valid. If it is, those without FI should give it a try.

At the end of the day, it really doesn't matter what is written. What matters is real world experience. That 30% increase feels more like 300%. Yes, it is that good.
