I have some exciting updates for you as we continue our world record ET and horsepower chase. While we haven’t made it to the track, yet, I am excited to announce that we have beat and currently hold the world record for the highest horsepower 10th gen 1.5t powered Honda Civic. Our car holds this record on the stock bottom end, tuned on the stock ECU and is running fuel available at our local gas station. Stay tuned for a demonstration and the final numbers… but before we give away all the secrets, let’s get you caught up on how we got where we are right now.
When we left you, last time, we were putting the finishing touches of the turbo kit together, installing and setting up the suspension and brakes and making accommodations for the Belak wheels and tires.
Over the last couple of weeks, we have been hustling hard, to put the finishing touches on our prototype turbo kit. Currently, our car is set up with a Garrett Gen2 GTX3071R which we intend to use to really push the power expectations of the platform as high as we can with the amount of room this engine bay has to offer and as you can probably tell, we have everything really show horned under the hood, utilizing every available amount of space we can as efficiently as we can. As we mentioned in our last video, we want to be able to offer a wide variety of turbo sizing options to suit our customer’s needs… this turbo is probably a bit on the large side, in terms of lagginess, but development for this size allows us to easily work back towards the smaller size Garrett turbos to present our customers with a powerful combination of performance and minimal lag.
Once we felt we had enough turbo to aim for records, we decided that we needed to wrap up the install of the Fortune Auto 510 series coilovers. We got the height dialed in where we wanted it, and took the time to align and corner balance the car. Obviously, to make records, we want to take advantage of every adjustment we can that will give us an edge, and these are the kinds of suspension adjustments available to help us control weight transfer… in the hopes of getting us off the line and out of the hole quicker.
With that in mind, we also put together a handbrake to help us stage the car. This will help us reduce the shock to the driveline during launches and staging. This kit is easy to use, easy to engage and is plumbed into the stock brake system in a simple way that allows for the easiest install and bleeding possible.
So now that you know what we have been working on over the last couple of weeks, I bet I can guess the question that is on everyone’s mind, namely “How do we plan on making more power when everyone knows that the fuel system is the biggest roadblock to making serious power”?
To anyone that asks that question… make sure to give yourself a gold star. Since day one, this platform’s small 1.5 turbo charged engine has been proven as a surprisingly power hungry engine that has been full of surprises, but when it comes to making anything over 400HP to the wheels, the fuel system has proven, even in the most capable of hands, to have been the biggest obstacle to overcome. I’m proud to say, the days of being held back are over and I would like to talk about how we were able to overcome our fueling issues.
Step one… add more lift pump. We went to the drawing board to develop a simple to install low pressure fuel pump solution intended to be easy to install for casual enthusiasts with minimal tools. Using a high pressure, high flow Walbro 450 LPH pump, we were able to substantially increase the fuel flow through the fuel system to allow for additional injectors without worry about the direct injectors starving for fuel.
Step two, add more injectors… to do this, we developed an easy to install billet spacer designed to optimize the fuel injector nozzle position in relation to the intake track. With only hour or two of time, and some basic hand tools, you can install this spacer and injectors and plumb the fuel rail into the fuel system with our supplied lines.
Step three, add a means to control the fuel… this is where the magic happens and since this a prototype kit we are using for testing, I will just say that our intent, with this kit, will be to be able to supply an affordable, but user friendly method for tuning these additional injectors. Over the coming weeks, we will be working hard to finalize the details of how this will plug into the existing car and be mounted… but rest assured, we will be doing everything in our power to keep everyone informed as developments occur.
So now that you know a little bit about the car, let’s take a look at what it can do on the dyno...and for everyone that might want to ask… our Dyno is an industry standard Dynojet 424x which is basically two state of the art 224x’s paired together and are capable of measuring 1500 plus all wheel horsepower. The outdoor temperature is 87 degrees with 33% humidity. Let’s see what we are able to get out of this little screamer.
There you have it. 513 peak HP to the wheels with 379 ft lbs of torque! WOW… let’s hope that is enough! Once again… this is a stock bottom end vehicle(Meaning stock pistons, stock rods, stock block, stock crank, an unopened stock shortblock), running fuel available from the local gas station(Roughly E60 at the time of this video), running a stock ECU making that power. Now there is a supplemental controller that is required to operate the injectors, to be completely fair, but the stock ECU is really running the majority of the show.
As you can probably tell, excitement is really ramping up, here as we get this car loaded up and ready to go down the track. Make sure to like and subscribe to stay tuned for our next big
