Rotary Tuning, Sim Racing Data and More | Today at HPA [UPDATE 256]

Why do people think rotary engines are unreliable?

In this weeks update that came before members only webinar '256 | Do You Need a Blow Off Valve?' with the impending release of the Data Analysis Fundamentals course via RaceCraft we're going to dive into some of the uses for track data in the real and sim world via which can be gathered with the likes of the AiM MXP dash logger, Solo2 or more options than ever on the market.

We also touch on one of the reasons why rotary engines have a bad reputation for reliability and how they do take some specific knowledge when it comes to the tuning side of things due to their unforgiving nature when it comes to detonation.

How racing seat technology has come along is also discussed in passing with a nod to Racetech's RT4100HR giveaway which features head restraints and also rear mounts on the seats so that we no longer just rely on what can be thin flooring to help save us from injury or death when things get a little too exciting behind the wheel.

The ability to 'affordably' (comparatively to 10-20 years ago) fit individual cylinder Lambda sensors is also touched on via a recent IG post along with how they do require a little more consideration when fitting comparing to your main sensor after the collector, and in our case on the SR86 we've used AEM weld-on bungs to help space the sensor out of the main exhaust flow to be less restrictive.

WEBINAR INFO: Blow off valves and turbochargers have gone hand in hand for almost as long as the turbocharger has been in existence. There are various theories about the requirements for the blow-off valve, including the ability to reduce the thrust load on the turbocharger and prevent expensive failures, and releasing the pressurised inlet charge air when the throttle is closed to help reduce lag or improve spool when the driver opens the throttle. In this webinar, we’ll do some investigation of our own and analyse what the data shows us using our Mazda RX-7 fitted with a Borg Warner EFR8474.
