convert rear wheel hp to flywheel hp

[383taman]

I dont know but if someone figures it out let me know cause my motor made 502/523 on the engine dyno. After it was in the car i put it on a mustang dyno for some touch up tuning and it only made 268/288 on it know i didnt lose that much. HAHAHA car ran mid 11s. All i could figure is the loose converter and spun on the mustang dyno. IDK didnt care was there for tuning.

The 15% & 20% methodology is just a generalization. Not intended to be exact - just ballpark.

Exactly every car is different there is no way to tell for sure. I dont think every car is gonna lose the same 40-50 HP
