Preignition can be BRUTAL

Описание: Preignition is sudden, often devastating and is not to be confused with detonation or knock.

Building and racing the world's fastest FJ20 with Dr Ben Diggles.

This is a short clip from HPAs Tuned In #podcast episode 089 https://hpcdmy.co/0891

Ben is somewhat unique as a Tuned In guest due to the fact he doesn’t work in the motorsport industry — as an accomplished marine biologist with a couple of doctorates under his belt, he’s quite far from it.

That career choice hasn’t stopped him from being one of the smartest people in the engine-building world, though, as Ben has spent his weekends for most of his adult life tinkering with cars — more specifically extremely high-output four-cylinder engines.

Down in our part of the world, Ben is well known for his work pushing Nissan’s mostly-forgotten FJ20 two-litre four-cylinder to its absolute maximum, first by building a 9.1-second Nissan S12 Gazelle street car years back that still holds the S12 world record, before moving his FJ expertise to a rear-engined dragster that has so far run a best of 6.7 down the quarter mile.

In this episode, Ben and Andre go way deep on ultra-high performance engine building, discussing different types of abnormal combustion and their causes, compression ratio considerations, mixture preparations, included valve angles, and much more.

There’s also a whole lot of FJ20 talk, including a comparison with a more modern gold-standard four-cylinder Honda K-series, as well as some surprising chats about the future of motorsport and the ever-advancing world of EVs.

There’s so much to chew on in this episode that it might require a couple of listens just to digest all the golden tech nuggets found within, this 60-sceond clip is like a grain of sand on a beach by comparison!
