Notes From a Recent Planning Session

Last week we sat down to map out the next batch of content for the workshop library. The goal was simple: figure out which diagnostic procedures deserve full teardown articles and which ones only need a quick reference card. What came out of that session is worth sharing because it changed how we think about the order of operations in a typical turbo build.

The main discussion revolved around boost leak testing. It sounds basic, but every tuner we spoke to has a story about chasing a misfire or a slow spool that turned out to be a cracked intercooler end tank or a loose coupler. We decided that the next full guide should cover building a leak tester from PVC pipe and a pressure gauge, then walk through the common failure points on a stock-to-midrange setup. That means checking the throttle body gasket, the BOV flange, and the welds on the intercooler core itself.

We also spent time on wastegate adjustment. The question was not how to turn the rod, but how to explain preload in a way that makes sense when you are under the car with a hand pump and a set of feeler gauges. The answer we landed on: show the relationship between actuator pressure and boost curve, then let the reader measure their own baseline before touching anything. That way the adjustment is a correction, not a guess.

The session ended with a decision about intercooler flow efficiency. We are planning a comparison of core designs, measuring pressure drop across a bar-and-plate versus a tube-and-fin unit at the same flow rate. It will not be a dyno test, but a bench test with a manometer and a shop vac, which is something any garage can replicate. That article should give readers a clear method for deciding whether an upgrade is worth the money or just extra weight.

If you have a topic you want us to break down next, the contact page is open. We read every message and the planning list for the next session is already growing.
