Engine Builder Pro
Workshop Calculators & Tools
Free · Designed for iPad. Not verified for macOS.
Engine Builder Pro brings engine build records and practical workshop calculators together in one place.
Create detailed customer build sheets, store measurements and component specifications, attach build photos, generate PDF reports and keep portable backups. Calculators can use values from the current job, reducing repeated entry and helping keep calculations connected to the build being assembled.
Workshop tools include:
• Static and dynamic compression calculations
• Target compression and engine stack-up solving
• Piston-to-valve clearance visualisation
• Cam degree and valve-train setup tools
• Carburettor sizing with camshaft inputs
• Ring-gap, rod-ratio, head-porting and measurement calculators
• Job-linked build checks and missing-input guidance
• PDF build sheets, photos and portable backups
Cam-card details are entered manually, keeping the recorded figures under the builder's direct control.
Engine Builder Pro is intended as a recordkeeping and calculation aid for knowledgeable engine builders. Users remain responsible for checking measurements, inputs, component instructions and final assembly decisions.
