Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Anyone considered trying this to improve airflow? Alaniz Tech is the leader for S2000s but is there another race shop for Caymans that does something similar? It is very sensitive/magic/art so am curious if any of the racing teams have done this. Jesse

That mod was standard fair back in the 70's. Bearing in mind most engines were far from high performance then. Now? Good question.

This is a source reference. Confirm exact model applicability in the original material.
