Gearhead Offroad calculates or estimates:
Speed/Gearing
- Engine RPM from vehicle speed, gearing, tire size
- Vehicle Speed from engine RPM, gearing, tire size
- Axle Gear needed for a specific RPM at a certain speed with a given tire size
- Tire Diameter and Cross section width from sidewall size
- Simple gear ratios based on drive and driven tooth count
Engine
- Displacement from cylinders, bore, and stroke
- Bore/Stroke ratio
- Static Compression Ratio
- Average Piston Speed
- Airflow
- Connecting Rod Ratio
- Maximum connecting rod angle from cylinder axis
- Compression Height (piston wrist pin height)
- Dynamic Compression Ratio from the point the intake valve closes
- Head gasket volume (from bore and compressed thickness if round)
- Valve opening and closing events from the cam duration, IC, and LSA
- Cam specs from the valve opening and closing events
- Valve overlap
- Valve lift based on new rocker ratio or lobe lift and rocker ratio
- Valve spring forces from valve spring specs to actual installed height and lift
- Mark dimension on your balancer to set a desired timing advance
Engine Externals
- Minimum air filter size for your engine
- Recommended header primary tube size for your engine
- Recommended exhaust size for your engine
- Cross-sectional flow area of a pipe, or the pipe size from a desired flow area
Suspension
- Instant center, Roll Center and Axis, and Anti-Squat of a 4-link rear suspension
- Cg height of your vehicle using the raise one end method
- Combined and secondary spring rates of a dual spring coil-over setup
Power
- Power from Torque and RPM, or vice versa
Fasteners and Threading
- Lookup cutting tap drill size
Fuel System
- Total Fuel system flow for fuel pump selection
- Fuel injector flow for injector selection
- Convert an injector flow rating to a new pressure or flow
