In this episode, we sit down with Mitch Pullen of Pullen Spec Engines, who specialises in putting together ultra-durable LS builds to discuss the ins and outs of these motors and much more.Use “PULLEN50” to get $50 OFF our HPA Engine Building Starter Package: https://hpcdmy.co/enginepackagebThanks to his father’s involvement in motorsport, Mitch Pullen started young, assisting in the pits and moving into the karting world at 10 years old. By 14, he was building engines, creating his own wiring harnesses, and figuring out fabrication. It’s probably no surprise, then, that he left school fairly early to learn everything he could about nearly all aspects of motorsport engineering.Although Mitch is a jack of all trades, he decided to focus on performance engine building, and this now sees him running the well-respected and very busy Pullen Spec Engines based out of the Gold Coast in Queensland, Australia.In this conversation, Mitch goes into detail about how he builds LSs, discussing their inherent weaknesses and strengths and the work that’s needed to create a motor that can sustain high horsepower and high RPMs for more than just a pull or two on the motorway or a run down the strip. Mitch is also well known for his unique S13 Silvia competition drift car, which runs a massive Roots-style blower sitting atop a Dart iron-block LS. There are a few obvious questions when it comes to this setup — why bother with this type of supercharger, how does it behave in a drift car, and can you even see anything when you’re driving? Mitch answers all these questions and more.The conversation finishes with some great discussions around car setup, forged vs cast engine parts, performance aircraft engine builds, and more.Watts linkage illustration: https://hpcdmy.co/wattsFollow Mitch here:IG: @pullenspecengines, @mitchellpullenFB: Pullen Spec Engines WWW: pullenspec.comDon’t forget, you can use“PULLEN50” to get $50 OFF our HPA Engine Building Starter Package: https://hpcdmy.co/enginepackagebTimestamps:4:08 How did you form an interest in cars?11:31 Did you do any formal engine-building training?15:09 Where did you go from rebuilding 2 stroke karts?20:07 Watts link vs Pan hard rod overview.24:53 Getting more power in the KE70.31:43 How did you learn all these skills at such a young age?32:52 What happened after the Khanacross?35:03 Learning about LS engines and circuit cars.45:40 Load on an engine for a sustained amount of time.48:52 What do you do in your LS to make it live?59:08 LS engine package.1:07:27 Forged vs cast pistons.1:16:52 Does the LS have enough factory clearance for boosted applications.1:27:16 Why the roots blower?1:35:57 Overview of Pullen Spec Engines.1:45:50 Focusing on the LS.1:48:47 Final three questions."},"annotations":[{"startTime":52.054,"endTime":57.333,"type":"car","title":"Nissan Silvia","url":"/cars/nissan/silvia","image":"https://upload.wikimedia.org/wikipedia/commons/8/86/1999_Nissan_Silvia_%2814372820470%29.jpg","quote":"...s to engine combinations for drifting.
