about 300.

Open the hood and there should be a sticker on the engine.

Not to the wheels. More like about 234 hp, or more importantly, 330 ft. lb. of torque at the crank. Depends on conditon, which dynamometer, fuel, tires and barometric pressure.

Real engineers NEVER use the horsepower word because it varies so much with rpm.

Notice how adverts push flat torque curves.

If acceleration is to be measured one uses torque as the calculations are simple and straight forward.

Since everyone's being vague and all over the board here are my numbers taken within the last 4 months.

Dyno 222.2 HP0-60 7.2 sec.

Major mods in progress since then and had a bad knock sensor for the Dyno test but those are my "mostly stock" baseline numbers. Had NICO stage 1 ECU and custom made CAI.
