Build Journal
Better value than a stroker? I believe so.
Beyond the traditional upgrades, making more power on the V10 has most often been answered with "Stroker!".
In 2023, I set out to challenge the hypothesis that camshaft upgrades were ineffective on the S85 in an attempt to rival strokers.
The end result will surprise you.
In this Series, I document the development of the S85-EVO high duration camshaft package as part of the Sxx-EVO programs.

SXX-EVO: High duration camshaft programs.
In 2023, I set out to empirically prove, or disprove an hypothesis: could we reach 125hp/liters on naturally aspirated S54B32, S65B40 and S85B50 engines?
As of 2024, I'm happy to report the hypothesis has been proven right.
