145@3000lbs shows 705hp on the Moroso chart.
Still pretty far off being within 10% of the dyno numbers(“supposedly” 880hp).

A motor that was dyno tested here a few weeks ago, making 728hp STP...... yesterday went 9.03@147, at 2875lbs.
147@2875lbs also shows 705hp....... which is within about 3% of the dyno numbers.

Edit- just got of the phone with the owner of the car with the 728hp motor.
Said he added an anti-roll bar to the car this past week...... adding 50lbs to it.
So, 147@2925lbs shows 715hp....... which is within 2% of the dyno numbers.
