ENGINEjr is the perfect companion to QUARTERjr for high performance engine design, and engine HP and torque prediction. ENGINEjr allows you to easily determine how much HP and torque your engine is making today, and how to modify it to make more HP and torque tomorrow! Now you can use your PC to estimate the performance of any engine you are thinking about building - V8, 4 or 6 cylinder, 2 valve or 4 valve, overhead cam, carbs, EFI, etc. . . before you even pick up a wrench, or pull out your wallet! In the past, the approach to engine building has been to copy what the next guy has and hope you get the same results. High performance engines are the result of careful parts matching, and the correct combination of parts is critical! What cam works best with my stroke, rod length and intake valve diameter? What size carb will I need? What if I increase the compression ratio or run methanol? ENGINEjr answers all these questions - quickly and accurately! ENGINEjr is based on real world, high performance engine dyno results! It uses a comprehensive parametric model that has been calibrated against an extensive database of known high performance engine dyno data. Combined with published internal combustion engine theory and textbook fundamentals this approach results in quick, accurate estimates of what any engine's HP and torque potential are.

Sample ENGINEjr screens for a typical 355 Sportsman engine are included on this page. Inputs include the bore, stroke and connecting rod length, compression ratio, fuel type, camshaft specifications, intake valve diameter and cylinder head flow data, etc. There are four powerful worksheets built-in for calculating compression ratio, estimating carb and throttle body flow ratings, predicting cylinder head flow, and calculating the critical minimum cross-section area at the intake valve throat. Any of the inputs may easily be changed using the editing features described in the ENGINEjr User's Manual.

.

The ENGINEjr estimated engine performance is located at the bottom of the input screen. It includes details on the peak HP and torque of your engine. ENGINEjr also includes the complete engine dyno curve, in both graphical and tabular format. Now it's easy to test new parts and ideas on your PC before you ever buy the parts and bolt them on!
