It’s true some people believe that there is no replacement for displacement, but that’s honestly a mindset that is becoming more and more obsolete with how good and easily tune-able turbocharged cars are. The latest is the with the turbocharged 2.0-liter engine.
The good folks over at Honda tuner Hondata with the 2.0-liter turbocharged engine, which is detuned from the ’s 306-HP output down to a factory-claimed 252 HP. Their readings found that it actually produced 266 HP to the wheels, according to .
(Keep in mind, though, that and that they’re best used to determine changes in output due to tuning.)
Of course, all of that effort was to showcase Hondata’s new toy: a FlashPro device with two stages. They claim that the Stage 1 tune increases the engine output up by 10 horsepower and 40 lb-ft of torque.
However, the Stage 2 tune adds an additional 40 to 45 lb-ft of torque, to make a total of about 80 extra lb-ft of torque over the stock motor’s peak output. And with a torque increase across the entire rev range, there’s a significant horsepower increase as well.
You can see Hondata’s findings below; the Stage 2 tune looks like it increases peak horsepower to about 285 at the wheels. And now for some Jalopnik math.
Let’s say the drivetrain loss for a front-wheel drive car is around 15 percent. If the Accord is now making 285 at the wheels, our equation would be: crank horsepower = wheel horsepower /85 percent, which gives us around 335 HP at the crank—higher than the Type R’s claimed power output.
that the tune increases mid-range (3,000 and 4,000 RPM) horsepower over stock by about 50 to 55 HP, corresponding to a torque increase in that rev range of approximately between 60 and 100 lb-ft.
Bear in mind that Hondata’s FlashPro only works on 2018 or newer Honda Accords with the 2.0-liter engine, as Motor Trend points out. It connects to the ODBII port and you don’t need any ECU modifications, but you will require a computer with a USB 2.0 connection.
I’m utterly charmed by this idea: Tuning a Honda Accord to have 335 HP? It’d be the ultimate sleeper car!
