This is more like 21-22psi or it has E85 or something. Even with E85 i don't see an extra 70 ft*lbs happening though. lol at spark blowout at 17psi btw. I've had it happen with a .028" gap on a copper plug at... yep 23psi of boost.
again, I have no idea what cam/tune you have. But you can clearly investigate for yourself every legitimate 2.0L in history pretty much produces the same amount of torque at the same air pressure because the cylinder total volume can only be the same size each time it fills. Air density plays a role obviously the larger the turbo the more dense the air will be at the time, which is why we use compressor map before purchasing turbo. Also remember E85 changes things a bit. FP turbo EVOS make 550ft*lbs but also AWD and run 32-36psi of boost E85 on 2.0L try a cross examination of theirs at 17psi to see what I am saying, you want double the torque you double the density with the same cylinder volume. |
That is my dynograph and it was between 19-20psi on 93oct. Timing was not extreme.
