Did not read all reply's, yea lazy. I would say just water grains alone would be big difference. Have seen quite a few engine pickup some when worn in. Rings seated. little more clearance hence less friction. Even little extra bearing clearance more oilf flow but less pressure which means less resistance for pump. There is reason those stocker guys pull a quart if need hundredth. Something very minor could be 16 hp.

I would be willing to bet $20 that after 30 or 40 runs and same weather as old numbers you will be close to tenth better or more. Yea that means broke but fee like you will see gains'

Am I seeing that right?

My car slows considerably from 20s water grains to 120s.



You can't burn water.

The swing from 20 GOW to 120 GOW is a major loss in HP. Water is the enemy of HP. Dyno testing in Texas is a absolute nightmare due to GOW.

You are running essentially the exact same ET and speed, only now you're 30lbs heavier and the air is much worse. Forget all the calculators, you're clearly making more power with the new motor.
