Honda CR-Z Projekt HYCAEI – Part 5 – The Conclusion. Having completed Projekt HYCAEI, it’s now time to run the engine and deal with any teething problems.

The first issue we encountered was excessive movement of the engine in a fore/aft axis due to the increased amount of engine torque.  The standard Honda engine brace is quite a flimsy component having soft void bushes which allows the engine to move quite a lot. We designed a more robust replacement, but whilst it was being manufacturered we filled the standard void bushes with a special compount to reduce the amount of engine movement in the meantime.

The brace at the top of the picture below is the standard Honda brace with filled void bushes, and the brace at the bottom is the new design with solid bushes. Problem solved!

After running the engine in and changing the engine oil and filter, we proceded to calibrate the HONDATA Flashpro

Using our Rototest hub dyno we were able to very accurately and consistently gather and analyse the engine parameter datalogs in order to tune the engine properly.

Considering that the initial objectives were to achieve 250hp at the hubs with 50 mpg, the resulting 280hp at the hubs with 50mpg is well and truly mission accomplished!
