On my dyno print out when my car is hitting 330 WHP it's producing 401 WTQ. That's at 3200 RPM. That's with the IS38 so your theory is incorrect.He's not correct but he is not wrong. I think what he was trying to get at is how the is20 delivers hp and tq is comparison to the is38. The is20 delivers more torque than it does power while the is38 delivers more power than torque. If you have an is20, if you want to get to 330 whp you'll be at almost 400 wtq. If you have an is38 and want 330 whp, you'll be pushing right around 320 wtq. With that in mind, you do in fact push the car harder with an is38 but you're pushing a lower amount of torque.
