Have you guys heard of Sprint booster
 

Hey guys check it out, let me know if that's total B.S. or it is worth the money.

Sprint Booster For Nissan 370Z

Already being discussed, search is your friend!

group buy going on at Home, a g35 site.

:( GB ended

I've installed one in my 10 370Z it's not BS by a long shot....I love it...

It's just a different throttle pedal map, not a big deal. Just push your foot down further.

makes my cell phone work better

I had been toying with getting one for my M3 before selling it... now I'm definitely interested for the Z. Need to justify the $$ to the wife though who has been watching my car/track expenditures like a hawk lately.

I had it on my Mercedes e55 and loved it. It just makes the tps or throttle more aggressive with less pedal if you know what I mean.
For the price it's expensive since the z is a new platform. But I'd get a tuner like an AP or Osiris that can be programmed in and you can have it to monitor values and reset CELs to boot.

Interesting concept but it really needs to be something like < $49.95. For $329.00 I'll step on the gas pedal a little further.

Well I ended up picking one up through a group buy on sixspeedonline last week. Ordered it Thursday and it arrived yesterday with free shipping and at a $85 discount.

Took 10 or 15 minutes to install and I have to say it has a noticable impact. I know there are people who think the same effect can be accomplished through a tune (along with the other benefits of a tune) and they are probably right, but for the $250 I paid, this was a pretty quick and easy plug and play improvement on the delay associated with drive by wire.

Car definitely reacts more quickly to throttle application and requires some adjustment in your throttle inputs (particularly in the corners). Really looking forward to trying it out at the track tonight (Infineon Road Course). Even my wife, who is pretty oblivious to changes in the car, immediately noticed the pickup in response.

When you say "pickup in response", does it remove the delay between pressing the throttle and the engine actually revving? I've found that with manual rev-matching downshifts, I have to be deliberate with the throttle blip. If you push the throttle too quickly, the revs won't even register to the throttle input. Does the Sprint Booster help with that?

By manual rev-matching are you referring to heal-toe downshifts? If so I'll have to let you know after I get the car on the track tonight. I know the delay you are talking about... it was a huge pain in the *** to me in my M3. Haven't had this car on the track yet and typically leave it with S-mode turned on when I'm on the street.

Well, yes-and-no. If you are heel-toeing, you are still blipping the throttle so you'd notice the throttle lag. But it happens if you simply stop at idle, car in neutral and quickly press and release the throttle. With the sprint booster, does the engine rev as soon as you press the throttle? Without it, there is a noticeable delay and you can literally push and release the throttle fast enough that the revs never budge.

In for results.

^^^ +1

Just my F U C K I N G luck! They are sold out and not due for months!

Never mind I found it! lol!

Well I wasn't able to do the indepth test that I had hoped as I spent most of my time focusing on short shifting to avoid the drop in power everytime I hit 6k RPM because I'm not running an oil cooler yet!

That being said, the car really performed well with the unit installed. Very easy to modulate throttle mid corner / at apex although I would suspect that if you aren't smooth with your pedal inputs you could definitely get yourself into some exciting (sideways) situations.

With respect to the question on blipping the throttle while in neutral, I think the delay is definitely improved although it seems like the improvements are most noticable when you're rolling along. Throttle response still isn't perfect, but I'm pretty sure I'm not going to be driving the car in any mode but 'race' from here on out. Really is nice when you're crusing along and want to punch it to pass...

Sprint Booster
 

Yes it is worth the money...but that's perception

If anyone wants a technical explanation of the Sprint Booster follow this link:

I ordered mine

I think I follow the white paper but think I may be missing something. If the throttle plate opens sooner and stays open longer during the course of the pedal's travel to the floor, than there is no way that there can't be an improvement in acceleration (even if its only slight). I did notice the 'dead' zone at the end of the pedal travel but it wasn't significant. I guess you just need to adjust your pedal work to account for the sensitivity on the front end versus the lacking response at the back end. It becomes a driving style preference. Which end would you prefer the pedal to be more responsive. That's the nice thing about the newer version which includes the ability to swith between modes.

I just received mine. Lets see what the hype is all about.

They state in their own information that there is no improvement in acceleration, this is all about making the car "feel" more responsive by amplifying your inputs. It's like changing out your steering rack with one that has twice the ratio, you'll turn in faster with less input but the turning radius is still the same as is the limit of grip. It's personal preference.

Totally agree that it is all about personal preference, out of curiosity where did you find that statement?

From this page.

Basically WOT is WOT as it doesn't change any engine parameters, you can't make the car's accelerator go to 11 (Spinal Tap reference).

This was worth the read. After understanding is happening under the covers, the last line of the 'whitepaper' explains it perfectly.

i wouldnt waste my money on this, for the price you could get a tune that would do this, afr, and produce gains...this is worthless..all it does is open the throttle more than normal at what ever pedal position your at

Yes, I highly recommend anyone considering purchasing read the whitepaper for a full understanding of what it does and doesn't do. Well written.

Bumping a very old thread - Does the sprint booster help the god awful throttle lag that occurs once the car is at operating temp? I'm one of the people experiencing bogging from a dead stop and terrible throttle input at lower RPMs - if I put my foot to the floor at 2500 RPM there is ZERO pick up.

Will this take care of it or do I need to go to a dealer to have them take a look?

The dealer won't be able to do jack squat for you - the stock throttle lag is terrible. A tune is the proper correction for throttle lag :twocents:

Sprintbooster simply increases voltage and tricks the car into thinking you pressed the gas pedal further down than you actually have. Overpriced for what it is IMO. But there are plenty of people who have been happy with their results using it.

It helped out my throttle lag noticeably, it made driving the Z a lot of fun. There will always be mixed feelings about the Sprint Booster but all in all I really enjoyed it.

I'm actually selling mine for $190 shipped anywhere in the U.S, I have ECUtek now so there's no use for it now, lmk.

I had a SprintBooster a couple of months back, but I have since taken it off and sold it. It does help the throttle lag a bit, the problem is that you run out of pedal travel really early and it feels weird to push the accelerator half way and have no more input after that.

I'm back to stock (awaiting a tune to address throttle response) and I much prefer it that way than with the Sprintbooster. However, don't take my word for it, try it out first and see how you like it.

:twocents:

I still have mine in my Z. It's good, not great but good. Improves the throttle lag.

so it is same as if you pushed the gas pedal more..... thanks for the clarification.

not really cause it multiplies the voltage vs otherwise a linear input from ur foot. it's like using positive expo on your RC car.
da last time i checked speed of electricity was faster dan my foot.

i see... i imagine that might make the manual cars harder to drive smoothly in between shifts especially from the 1st to 2nd gear.

not if u get use to it. i can drive fine. smooth shifts and all.

It actually smooths out your shifts because the rpm spikes quicker than without. Ive had mine on red almost a year and no way it's coming off unless I finally decide to get tuned or selling my the car.
