BenzForce Performance Calculator
HP to Fuel & Boost Calculator
Welcome to the BenzForce Power Calculator. This will help estimate boost pressure and how many CCs you will need to achieve your power goal. Please keep in mind that real world results will vary. After this calculator was made, adjustments were made to closely match Dieselmeken's om606 testing with a 140cc pump and BorgWarner s257 that made 427 horsepower.
Inputs
Outputs
Required Boost
0 PSI
Gauge boost required to support target HP.
Pressure Ratio
0.00
Corrected pressure ratio after temperature correction.
Airflow
0 lb/min
Estimated airflow needed for the horsepower target.
Fuel Delivery
0 cc
Estimated pump delivery in cc per 1000 injection strokes.
Calculator Assumptions
- Designed for a 3.0L 6-cylinder engine
- Volumetric efficiency default is 85%
- Atmospheric pressure default is 14.7 PSI
- Airflow estimate assumes a 4-stroke engine
- Diesel fuel density assumed to be 0.85 g/cc
- BSFC default value is based on a performance diesel engine
- Horsepower values represent crankshaft horsepower unless otherwise noted
- Turbocharger efficiency is not modeled
- Exhaust backpressure is not modeled
- Cylinder head flow restrictions are not modeled
- Camshaft effects are not modeled
- Results are estimates and should not replace dyno testing
This calculator is intended as a planning estimator, not a final tuning or engine safety tool.
