  There&apos;s been some questions about direct injection and carbon build-up on engines with this technology. I have asked about this with various engineers over the years and they have responded that the higher PSI of the spray nozzles, it atomizes the fuel better and removes this concerns. Here&apos;s an example of this explanation at the 3.28 mark of this video with a Chevy engineer. He is talking about the 6.6L gas engine, but this same information applies to most other gas engines. If you check out the spec charts online, you&apos;ll find the gas pressure spray PSI level for most is well above 2,000 with some being higher. The Hurricane engine has a &quot;single high pressure pump providing up to 5,075 psi (350 bar) to a single fuel rail.&quot;<br><br><a href="https://www.youtube.com/watch?v=A_VaFCpQ9nY">https://www.youtube.com/watch?v=A_VaFCpQ9nY</a>

  Nobody will ever be able to convince me that start/stop technology is a good thing or actually saves a material amount of fuel or emissions.

  I notice whenever engineers are discussing new vehicle/engine designs, they rarely talk about longevity in terms of 5-10 years down the road.

  I&apos;m pretty proud of myself for often knowing what the engineer was going to say next. Especially since I was fired as a mechanic.. best thing that ever happened to me. That job was replaced with a career.😊

  I don&apos;t care what anybody says, removing a physical dipstick to check the lifeblood of the engine is a stupid move. &nbsp;And honestly it&apos;s a slap in the face to the consumer.

  Tim, I understand that most people outside of your forum and similar forums are likely not as meticulous about their vehicle maintenance so the engine not having a dipstick is not something they would even miss, but there is no way I would ever buy an ICE vehicle without one. <br>Given what you experienced with the LZ0, I cannot imagine owning a diesel powered vehicle without an oil dipstick.

  So glad I bought a 5th gen Ram when they first came out. 5.7 hemi, no etorque, anti slip, 3.92 rear axle, 4x4. Everything I wanted in a truck.

  There is one thing that is positively true. You won&apos;t have turbo troubles on a normally aspirated engine.

  My first turbo car was an 86 Dodge Lancer ES turbo and it was one of the most reliable vehicles I have ever owned. I have been driving turbos ever since. In fact, I still have an 86 Dodge Daytona Turbo Z that I drive hard the first 5 years I had it and it had a 145K miles on it with the original turbo when the transmission lost second gear drag racing it. I also have a 2022 Jeep Grand Cherokee 4xe with the Hurricane 4 and love it. So I completely trust their durability.

  Great interview. I&apos;ll have to give it a second listen, got a bit distracted in the live chat. Cheers to Alan for taking the time to do this.

  Once again some very good information regarding the 3.0 L Hurricane Engines, directly from one of the Engineers who designed the engines. &nbsp;Thanks again Tim, for your ability to get this kind of information directly from the source!

  There’s a reason why BMW has had so many inline 6 engines on Ward’s top 10 engines list - they really are inherently smooth. Also, they’ve been turbocharging them for a LONG time now (granted, it’s a much more convoluted system.)
