|4.4L vs 3.8L AMS Alpha 10|
Some guys like to do it with a 3.8 some like to do it with a 4.3. AMS shows us what they can do with 4.4 liters.Going from a 3.8 to a 4.4 on this setup HP and TQ just shot up everywhere. Peak torque went up by 140 ft lbs but as illustrated by the blue area it carries a ton more tq all the way throughout the power band.HP got a healthy bump too with over 100hp more in almost all areas in the midrange and tapering off to about 50 more HP near redline.
