Engine Block Design - Cast vs Billet
Show Notes

What considerations go into taking a 150HP engine and making it produce 600HP with huge cylinder pressures, reliably? 

When you want to double, triple or even octuple an engines output, at some stage you’re going to find the limitations of your factory block and head castings either in dramatic fashion or via constant repairs and rebuilds for ‘minor’ issues. In professional motorsport, either outcome is unacceptable.

David Mountain of MounTune runs Andre though some of the block failures they have seen during their engine development programs where very high cylinder pressures are seen to produce large amounts of low-end torque for World RX competition engines where they are running 4 times the power the engine would produce in factory trim.
