Instantiating a GameObject relative to another object's position and rotation

Heres a vid of whats happening: - YouTube

The Green bullets spawn with the correct off set relative to the object at the starting rotation but not the rotation after turning the object.

This is the code that spawns the bullet

	public void bullet(){
		Debug.Log (this.gameObject.transform.localPosition.z+2);
		Vector3 spawnPoint = new Vector3(this.gameObject.transform.localPosition.x + 1.1f, this.gameObject.transform.localPosition.y,this.gameObject.transform.localPosition.z+1.1f);
		GameObject fire = Instantiate(projectile, spawnPoint,Quaternion.identity);
		fire.GetComponent<Rigidbody>().AddForce(this.gameObject.transform.up * firespeed);
	}

You can actually save yourself a lot of typing here.

public void SpawnBullet () {
    // multiplying a rotation by a vector applies that rotation to the vector
    Vector3 spawnPoint = transform.position + (transform.rotation * new Vector3 (1.1f, 0, 1.1f));
    // ...
}
