SXX-EVO: High duration camshaft solutions.
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.

More, always more.
When I bought the S54 powered E46 M3, I told myself I'd Stay Melo. If I needed my fix for NA power, I'd grab the keys to the V10.
And then I got to drive the E46 M3 with the CSL airbox and Supersprint complete 63.5mm exhaust.
It was this close to having enough power, but it just wasn't enough.
In this Series, I document my quest for optimizing the S54.
Cheers,
