Field Report: What do 2-stoke Detroit diesels and this LS V8 have in common?

Let's be honest, power is easy to make these days. Anyone with a modest budget can build a 1000hp dyno queen, but what about high-output engines that are expected to last for more than just a few full-power dyno pulls?Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-inMixing a unique roots style blower (aka supercharger) with 8-into-1 headers for wow factor, Mitch Pullen of Pullen Spec Engines hasn't glossed over the essential parts to ensure this LS-based build will last. Improving rod angle, slowing piston speed, and choosing a stout valvetrain option over pure peak HP figures are all part of this, along with running a dual DBW throttle fuel-injected setup with 16 injectors over the carburettors you'd typically see on a setup like this.Why roots-type blowers are considered so inefficient compared to other supercharging and turbocharging options is discussed, along with individual cylinder trimming and running rich 0.80 lambda of E85 fuel to help cool combustion charges for 8 PSI of boost, making an easy 800hp during the Garrett International Drifting Cup at World Time Attack Challenge.TIME STAMPS:0:00 - Blown S130:30 - Why The LS0:54 - Roots Blower1:38 - Haltech NEXUS R51:55 - PDM & Can2:26 - 16 Injectors2:58 - Primary Injectors3:05 - Fuel Cooling & Lubrication3:12 - Trimming Injectors3:20 - Liquid Intercooling3:55 - Why A Roots Blower Is Considered Inefficient4:24 - Boost Pressure4:58 - Pre Supercharger Fuelling5:28 - Ethanol Fuelled5:35 - Fuel Mixture & Cylinder Trims6:12 - EGT-Based Fuel Trims7:45 - EGT Temperatureres8:03 - Transient Throttle Tuning8:32 - Acceleration Enrichment9:23 - Short-Term Fuel Trims10:47 - LS Engine Specs11:14 - Why Short Stroke?11:49 - LS Rod To Stroke Ratio12:43 - Dart Block13:30 - Power Level & 8,800 RPM13:55 - Cylinder Head14:30 - Rectangle Vs Cathedral Port
