Sprint Booster review for 370z 7 speed AT

Alfamale · 12-30-2010, 03:20 AM

i was a sceptic at first.. thinking meh, just another snake oil application alongside those sh*tty fuel-saving magnets bullsh*t but after sat in my fren's civic type R with sprint booster installed...boy was i blown away!! really eliminates any delay, response is spot-on immediate!! I'm totally sold.

To those who are still a sceptic, go sit in one and see for yourself.

there are many reasons the sprint boosters seem to work well, most of those reasons are stuff people don't think about really, first off there is the placebo effect just putting the thing in will make you think it is improved, then there is human lag time, between you thinking about putting the pedal down and your foot actually doing it there is over a half second of lag in your own brain, also most people don't just slam the pedal down, so there is lag there. people with better reflexes, a stronger ankle, and a better feel for modulating a gas pedal will have less lag.

The only real reason to buy a sprint booster is if you desire a shorter gas pedal travel, because that's all it does, it shortens the pedal up electronically. pushing the pedal down 75% with the sprint booster on is the same as full throttle, the last 25% of the pedal stroke means nothing so all it does is shorten the time it takes you to actually push the pedal in all the way. Some of these pedal tuners actually increase the throttle percentage while depressing the pedal but once you stop pushing it in farther will ramp back down to the real percentage so say you push the pedal from 25% to 80% it will tell the car you pushed it in 100% while your foot is moving and then drop back down to 80% once your foot reaches it.

To actually increase the cars responsiveness(instead of your foots) you need to do things like tuning the acceleration enrichment, the ETB logic, the spark maps, the rotating inertia, the torque band, and things of that nature all of which cost a hell of a lot more than $300.

Anyone know of any group buys for this thing?

don't buy it, just floor the damn thing, our cars have over 280rwhp!!!!

This device addresses and improves one of the weakest links in the chain of driver to car to road: the right foot.

If you want no lag, downshift into whatever gear will put you at 5500 RPM in anticipation and then floor it. Use SRM if you need to and try to tell me there's a delay trying to push it through that yellow light. There's only as much lag as time it takes you to downshift. AT folks - maybe this is a good alternative to having to use manual mode all the time.

A very experienced driver can essentially do what this device does by varying his driving methods. But the fun factor of a device like this makes is perfect for some people. I would akin it to SRM for someone with limited or no heel-toe ability who wants to track. I would definitely like to test drive a car with SB to see the difference.

So it does not increase throttle response, just pedal response? Then I guess you could get the same result by driving harder, or fitting a spacer into your pedal.

I just don't get the "slow" or "lag" throttle issue. Never had it with mine.
