The Papi Express

Let's get to work.
In this entry, we finally get the S85-002 on a stand and get to work. The last accessories are removed, the V10 is drained and we turn it over to start with the obvious: connecting rod bearings - with a new twist.
Shifting market dynamics.

In this entry, I document the current market dynamics of sourcing a quality S85 engine. I set my minimum requirements and I get my hands on my S85-002. We briefly inspect and undress common accessories.
S85s were not created equal.

In this entry, I document the changes made by BMW M to the S85 in attempts to improve its reliability. I cover which changes are worth it based on historical reliability and my experiences.
The F1 heritage is real.

In this entry, I go in-depth on the history of the V10 F1 era, the BMW Motorsport F1 program and what remained of its influence on the S85 V10 development.
Same same but different.

On this entry, I finally received the Schrick cams from Germany along with auxiliary hardware. I chat S85 differences, the theory and specs.
I gave you everything.

I earn a badge of honour: I blew up my V10. I discuss my year long use, the previous owner's maintenance records and my own service regime. We set hypotheses and probable causes of failure.

My M5 V10 Programs

Named "The Papi Express", this is ironically the teenage dream car. I'm attempting the impossible: creating the unreleased E60 M5 CSL.

I sourced and develop products for likeminded M5/6 V10 owners to achieve their build goals.
