06 Tacoma hp ? and hood option ?

[Dutch]

I just noticed that the horse power rating on the '06 Tacoma V6 model is 236hp, compared to the '05 model, which was 245hp. Anyone know why the loss of power for the '06?

Also, does anyone know if the scoop hood is going to be an option for the 2006 model Tacoma?

The engine will have the exact same power as the 05. The difference is that they just changed the standards by how they measure the HP.

"Under the new SAE standards, new power ratings are as follows:

1GR-FE, 4.0L V6:
236hp @ 5200rpm
266lb-ft @ 4000rpm

2UZ-FE, 4.7L V8:
271hp @ 5400rpm
313lb-ft @ 3400rpm

245hp to 236hp is a 3.67% decrease, but is probably more accurate. The 1GR also takes a 5.67% drop in torque.

The 2UZ keeps the losses under 4%.

Keep in mind, the engines didn't actually lose power, but the way that the power is measured has changed. Also keep in mind that if the tests were run using regular unleaded, the knock sensor was retarding the timing, thus exaggerating the power "loss."

Also for reference, the 1GR-FE puts out 207rwhp, stock. Multiply 245hp by 84.5% (0.845) for drivetrain loss/efficiency or 236hp by 88% (0.88). Both yield around the 207rwhp mark. In other words, rating the 1GR at 236hp actually increases its efficiency. Only about 12% of power is lost through the drivetrain. At least, that's what I've extrapolated from the dyno."
