Supercharger and turbo efficiency

The last two seasons I have been pushing harder than ever on the track resulting in lower lap times with basically the same engine power.  More optimal driving results in...

January 2018 the user whalesac on miata.net posted a very detailed post on using the Chrysler 74mm drive by wire throttle body as a replacement for the stock 60mm unit:...

Jet Stream ram intake install

As I outlined in this post I want to optimize the intake for better flow and hopefully lower initial IAT measured at the air box.  The stock setup is actually...

Measuring exhaust backpressure on stock exhaust and FMSC.
