I would like to start this blog by saying thank you to The Dyno Shop. They were punctual with my appointment, getting me on the dyno right away. They were careful with strapping the car down and I was provided a dyno printout with A/F ratio readings from the tailpipe.
Now lets talk numbers. Below you can see a dyno graph from a 2010 AT Corolla, also equipped with a 2ZRFE it puts down 119hp, 113ftlbs using an intake and full exhaust. You can view the video here:
Now going into this dyno day I had expected mid to high 120's from my 2ZRFE mainly because of the highly coveted RPM long tube header. And on top of that, when my buddy Arnel raced the 2zrVios last month with me...he mentioned it seemed low on power. I connected a SnapOn scan tool to the car and went on a test drive to verify the car was in closed loop and that the dual vvti system was fully functional...All was well. So lets see what the internet has to say:
132-138hp and about 126ftlbs at the crankshaft. So with these numbers if we assume this particular corollas engine made 138hp, then drivetrain loss is 13%.
Now lets analyze the 2zrVios graph:
While I do understand this isn't a lot of horsepower, but any time you're able to put down to the wheels more than an engine is rated at the crank.....N/A......now thats quite impressive! And now if we add the assumed 13% drivetrain loss as stated earlier, we end up at....157hp, 147ftlbs at the crank!
There are a few things we could do to squeeze a bit more power out of this 2013 Corolla swap, like an intake, a lightweight flywheel, and lightweight pulleys...but what's most important going forward is a tunable ECM. Next year we are planning to convert over to some form of tuning capable hardware, that way we can find the true limits of this engine before we start a real engine build. Thank you for your support as always and enjoy the video below.
