Review & Install Video
Hey, guys, it's Joe from AmericanMuscle. And today, we're gonna be taking a closer look at the Sprint Booster V3 power converter, fitting all '08 and newer Challengers. Now, this is gonna be the perfect mod for any Challenger owner out there that is just unhappy with the way the throttle pedal feels in their Dodge, and they're looking for an easy-to-install and quick mod that's gonna help fix that problem.
So, in order to understand what the Sprint Booster does, we need to go back in time, talk about how throttle pedals used to work and how they work now in the modern day. Back in the old days, it was a simple mechanical connection, whether it be with a linkage or a throttle cable right to that butterfly valve in the throttle body, so when you press the throttle pedal down there is no lag whatsoever as it's a hard connection. Nowadays though, car manufacturers, they take the easier way out, and that is to do it with computers. So, what happens when you press the throttle pedal down in any modern Challenger, it sends a signal to a computer, which then sends a signal to your throttle body telling it to open to a degree according to how far you press the throttle pedal. Now, that is all well and good, it makes cars a little bit easier to design for the manufacturers. It doesn't exactly lead to throttle response, because even though computers are fast, it does lead to a little bit of what we call input lag, and this is where something like the Sprint Booster V3 power converter can help you out.
Now that we have that out of the way, we can talk about what this does, and all it's gonna do really is up the voltage from the throttle pedal to the computer, which is going to trick the computer into thinking that the throttle pedal is pressed further down. That's gonna give you a snappier response, and it's gonna open that butterfly valve in the throttle body a little bit further. Now, the Sprint Booster does have three modes to it, so you don't have to go in all out race mode all the time. There's "Off," which is basically just gonna be stock, and then there's the green mode, that's gonna be your sport mode, and then there's the red mode, that's gonna be the full out race for the most throttle response. Each of those modes, sport and race, they each have nine levels of individual adjustment so you can really dial in the response of your throttle pedal.
This one does have two features about it that I do really like, one of them is the pedal lock, which means once this is in that setting, it's not going to allow the car to come off of idle. And then there's also a valet mode, which isn't gonna let it rev all the way out to the red line just in case any valets wanna Ferris Bueller your Challenger. Another great feature about this one in particular, no computer tuning required, completely plug and play. This is just gonna drop right in right before our throttle pedal, which means if you don't like this, take it out, and you're completely back stock.
Now, one thing I do wanna be clear on, and this is gonna go to all throttle controllers out there, not just the Sprint Booster V3, is they are not going to add any horsepower. Once the throttle body is open, it's open, it opens 90 degrees, doesn't need to open any further than that. So, this is not going to make any horsepower, this is gonna be for the guy that's just unhappy with the way their Challenger feels when they press down on that throttle pedal, they're looking to up the response, and get that throttle body open a little bit faster, a little bit more responsive under the right foot. If you fall into that situation, this is gonna be the perfect mod for you.
Pricing gonna drop in right around that $300 mark, and again, you're gonna know if you need something like this. If you're just unhappy with the way that throttle pedal feels, this is pretty much gonna be your end-all, be-all solution. Install for this is gonna be a simple one out of three wrenches. Like I said, completely plug and play, no retuning, no wiring knowledge necessary to get this installed, should take you about 15 minutes with no tools whatsoever in the driveway. One thing I do wanna mention is, it's a little bit tough for our camera guy to see in the footwell of any Challenger, it's just really cramped, we're gonna show you how it's done outside of the car first, and then we're gonna do our best to show you the inside of the car. So, without any further ado, let's head over to our Challenger, bring this with us, and I'll show you how it's done.
So, over by the Challenger, and like I said earlier, things in that footwell are pretty tight. So, I'm gonna try to tell you how this works outside of the car first, and then we're gonna do our best to show you what it will actually look like. But it's really really simple, you guys probably won't even need me to tell you how to do this. This cable, it's going to install right before our throttle pedal, so we're gonna take the factory harness off just by pressing in a release tab, then we're going to install this end to the factory cable. One thing to note is, before we do anything, we're actually going to install our switch with that white connector right there. And then on the other end, this is gonna go to our throttle pedal, that's gonna click in, and then we can lock it down with that red tab right there.
So, down here, what we're gonna do is push up on this felt, and then grab that release tab, and that guy should pull right out of there. And then we're just gonna grab this end of our throttle controller, [inaudible 00:04:59] right in there. You can hear that clicking, like so, and then this end is gonna plug right back into our pedal, then you push that red tab down. So, now we just have to mount up our switch, control box, whatever you wanna call this thing. The kit does include a little bit of adhesive. So, all we're gonna do, peel off one side, stick that to the back, and we can peel off the other side. I have to admit, it's easier said than done. Boom. Now, you can put this box wherever you want, there is plenty of wire here. Speaking of which, the kit does include a zip tie for you to wire manage that, however, you do wanna make sure this doesn't get tangled in your pedals, especially the brake, that would be the last thing you'd want.
Guys, that is gonna do it for me, it's also gonna do it for the Sprint Booster V3 power converter, fitting all '08 and newer Challengers. Thank you, guys, for watching.
