You know what. I'll share with everyone my list of questions and you can chime in if there is something I'm missing. Another big benefit to being a forum member!!
Just to be clear, I don't normally put together a list of questions beforehand. However, the software I use, let's people add their own slides and videos. This means it is actually a better video overall if they, the engineers, can see the question and gather the relevant charts or video/s before the interview. Like the durability video I reference below. Wait until you see that one!
Questions:
History - I'd like to start with going back in time first.
- when you knew the Hemi was going away and you had a blank slate for a new engine to be developed, why go with an inline 6? Why not say an inline 4 or a V-series?
- why couldn't the Hemi V8 be updated to meet emissions?
- How long was the development process for the Hurricane?
Durability - let's see that video again he showed at the presentation!
- I know automakers don't like to talk about durability in terms of miles and I won't be asking that question. Instead, I'm wondering what can be shared about the durability process without giving away corporate secrets. For example, I know you run the engines at red hot temperatures to see how they perform. Can he speak more in-depth into that process? Also, I'm keenly interested in the turbos since their durability continues to be a big concern.
Cooling
- speaking of turbos, I know cooling is a key part of turbo longevity. And I know there has been a lot of engineering put into cooling. Frankly, I'd like to just ask the question and let Alan go with whatever charts, images and what not to share. I know I missed part of a discussion he was having with another journalist about cooling and I'd like to get that on camera. IIRC there was something about a cooling setup on the passenger side of the engine using water. Hopefully that sounds familiar.
- I'd also want to discuss cooling with regards to towing and the J2807 standard. My understanding is cooling is the really limiting factor for most engines and not HP or torque to meet the towing standard. Is that correct?
Oil type, intervals
- It never ceases to amaze me how people are ok spending tens of thousands of dollars on a new truck and then want to argue about what oil to use. Let's discuss that.
- What oil type do you recommend? I've heard the lighter weight oil is for fuel economy and I've also talked with mechanics who state the lighter oil is also due to advancements in engine design. I'm going to assume both are right and I'm wondering where Alan is with this thought. Also, maybe share what oil type was recommended when he started and discuss why the change over the years.
I'm also curious how much interaction there is between oil companies and engine engineers. Without naming names, do they come to you and try to pitch you new oil types?
- What oil interval do you recommend? Frankly, I can't believe the arguments over this item as well online. Can he shed any light on why we are doing longer intervals?
- Is there such a thing as break-in oil? What is the engine break-in process and what is the goal of the engine break-in process? For example, can I damage the engine if I tow immediately?
Starter
The concern is the starter reliability with start/stop systems.
- is start/stop bad on the engine? Will it cause the starter to die faster?
I've been led to believe the starter is a lot different than it used to be. I wonder if there's a photo of say a 2010 starter versus a 2024 starter.
Final question
This is a fun one. What is one thing Alan has seen online about old school engine thinking that just doesn't apply anymore?
Examples I came up off the top of my head:
- Carbon buildup is a massive issue and you MUST have direct and port injection to clean it.
- cylinder deactivation uses oil and is bad for the engine.
- turbochargers are a ticking time bomb
- new turbo engines don't need that much cooling
- light-weight oil will damage the engine due to not being thick enough
