272. Gender: Male. We know the 2016 2.7l 2tr-fe engine in the 3rd generation tacoma has been changed. We know the compression ratio has been increased from 9.6 to 10.2 and the engine now has variable valve timing on the exhaust side giving it DUAL vvti status. Toyota leads us to belive that the new engine has (been detuned?) to the exact
The peak torque rating for the dual VVTi engine is slightly less than the single VVTi engine, and the torque peak occurs at 600 RPM higher, but the torque curve is much flatter, and there is slightly more usable torque at lower-to-midrange revs.
In terms of performance, this type of engine also has maximum performance because the Dual VVT-i can adjust the opening and closing times of the intake and exhaust valves. In addition, the power and torque are better. Not to mention the presence of a resonator in the air intake system which provides more intake.
In case one cannot find a 2010+ model for Dual VVTi , for 7000dhs you can get original Toyota Racing Development superchargers that are available for Single VVTi then the Single VVTi will beat both HP and Torque of the Dual VVTi 😄. I've seen it reaches 580hp for 1GR-FE Single VVTi on Supercharger 🔥 Food for thought for the Prado owners
Push the VVT onto the cam. Install the center screw, and tighten slightly. turn the VVT unit counter-clockwise as far as it will go. Remove the center screw. Put the upper timing cover. Turn the timing gear pulley clockwise until the screws on the holes are at the limit position.
Jawabannya adalah cukup sederhana. Untuk menghitung waktu pembukaan dan penutupan (valve timing) yang optimal, ECU menyesuaikan kecepatan mesin, volume udara masuk, dan posisi throttle (akselerator). Perhitungan ini disesuaikan dari pedal gas dan beban mesin. Sementara itu, teknologi Dual VVT-i adalah pembaruan dari VVT-i.
