The Mix & Match technique is how i named the company Frankenstein Motorworks. I love repurposing stuff in unintended ways :)

To answer your question about the 2AR-FXE’s “increased” compression ratio, Toyota counts the intake manifold area towards the total cylinder volume at BDC and dividing that by the volume at TDC when both valves are closed. When you adjust the Atkinson cams to behave like Otto cams you cancel out this affect. Your build is blowing the K series swap out of the water IMO, keep up the great work.

@roman3s

Жыл бұрын

Why does everyone keep saying this? The static compression ratio IS high, then they reduce dynamic compression ratio by keeping the intake cam open. Dynamic compression to more like 8:1 or whatever for less pumping losses. FXE motors have different pistons to the regular motors, and the compression IS higher.

Not only was the increase in torque impressive...the flat delivery is even more impressive !

No i have not but i have a 2ar-fxe piston on the way so i can compare the piston dimensions and measure the exact compression difference. I'll probably have a follow up video in a week or two about this.

@@FrankensteinMotorworks 12.5 is correct, compression ratio always refers to geometric since "Atkinson cycle" is just a different cam. I think you didn't get the increase in power you hoped for possibly because 12.5 is a very high compression ratio for pump gas on a port injected, low tumble motor. E.g. the Lexus LFA had bigger cams and 12.0 compression. Did you tune it by adding timing until it knocked, or until the torque was maximized on the dyno?

I will have to dig up some Toyota data sheets. I could have sworn I remembered they used Atkinson magic for that compression. I'll try digging up those diagrams to make sure I'm not spitting garbage

Kyle, Due to the trigger pattern on the cams there's no way this would work on the stock ECU. You would have to modify the trigger part of the camshafts to make the stock ECU happy.

very little difference actually. but yes i did get a bit of knock but nothing that was hard to manage. E85 would make a tiny bit more power in a few spots but this motor is not very knock limited even at 12.5:1 CR

your answer is too much duration in the cam, so thats where your losses are

It's possible but the longer cams had higher volumetric efficiency at high RPM so this is unlikely to be the issue. But sometimes resonances can be a bit weird.

@@FrankensteinMotorworks oh ok I really dont understand this because I thought the FXE motors were given a longer duration to keep the valve open during the piston compression stroke, pushing out fuel and air and effectively LOWERING the compression ratio... but maybe I am wrong, I thought you had to change the cams to get it out of atkinson cycle

@FrankensteinMotorworks

@@PseudoKirby you're 100% right that the way Toyota implements the atkinson cycle is by leaving the intake cam open for a long time. I took advantage of this fact to get a very low cost long duration cam. When i build this motor i advanced the cam by 20 degrees to turn it from an atkinson cam to a performance cam (note that the vvt-i is still there so the ECU can advance it a further 50 degrees or so). I also use a 2nd atkinson intake cam in as an exhaust cam to get a motor with two long duration cams. You can see the build in this video: kzread.info/dash/bejne/o2yowdKYp8S1ddY.html
