Is is warmer outside than when you ran the faster times? More humidity? Gas or ethanol ratios from different places or not checked? You probably need a few more runs under similar circumstances to get a real average.

Just curious, where do the readings come from? Logging via the HP Tuners App? I wouldn't think elevation or ambient temp would affect actual octane ratings, so is this number an "effective" octane number? Second, due to seasonal variations in ethanol, wouldn't this also affect the readings?

Although it looks like I answered my own question, the site: https://www.liaviator2.com/lincoln_aviator_assembly_engine-2613.html has a lot of info on the 3.0 engine as well as pics.

Finally came across this from aviator service manual- shows hydraulic finger followers: https://www.liaviator2.com/lincoln_aviator_assembly_engine-2613.html Here was the Ford site: https://www.ford.com/suvs/explorer/models/explorer-timberline/ Scroll down to Engine Specs- lists mechanical...

I've been doing research, and recently posted that the 3.0 engine had a hydraulic finger-follower valve "rocker" based on info from an internet site. Then, I was looking at the Ford site which listed mechanical buckets. Now, not that this is a big deal, but does anyone here know for sure?

Hey, he corrected "lumber" to "lumbar" in his thread! Now it makes much more sense!

Fair enough.

I posted some information which may not have reflected the actual strategy of the ecu, but it certainly wasn't information that was patently wrong. I even posted the disclaimer: I remember a post ZFG made on this very subject a while back, try searching his posts to find it- as I remember he...

I do not have experience with the ECU on this model, so you're right, I'm probably out of date! So, just for grins, I could actually run say an e30 tune with no tuning on the factory ECU and see performance improvements? It would actually add boost and timing and enrichment? Seems to be what...

Think about an 87 vs 93 tune. At WOT, both are using approx the same amount of injector, but the timing and boost amounts would be different. So, if you have an 87 tune (for example), the 93 wouldn't add anything, but if you're running a 93 tune and use 87, then hopefully the knock sensors...

Do a search on FENG (fake engine noise generator) on this site. IIRC, there are forscan settings that can turn it off.

I'm curious about that too. Return from the chain tensioners? I'm sure zfg will let us know.

So, are are saying the pan is far enough below the webbing that the baffling provided is insufficient? I certainly get that due to the front end lift and g force, there would be much more effect on oil flowing away from the pickup. As a follow up, do I understand that the oil pump is pretty...

After giving it some thought, I'm thinking the next possible culprit would be a volume issue. Hear me out, in the area directly around the pickup between the webs and assuming the oil level is below the crank, it certainly seems that there isn't room for more than (maybe) a quart or less of oil...

Interesting. It would certainly appear that the cross webbing would do an adequate job of baffling the oil movement while the "tray" would allow adequate clearance to drain back to the pump. So much for the injection molding casting being the source of the baffling. But seeing this, I don't...

Thanks for sharing those pics with us, I'm looking forward to seeing more! In relation to your post on oil starvation at launch. Could you please post pics of the pan, pump, and pickup? From what I have read, the variable oil pump is driven off the front of the crank. Which would suggest the...

You can bet there's some engineering leeway built into the torque spec. And it's a static measure, so if you locked the output shaft in a vise (for example), and started twisting the input shaft with a really, really long torque wrench, theoretically something would go "pop". But that's not a...

I don't know, but direct me to the pics and I'll look. In a v6, because of the shortness of the crank, you just don't see them break unless there was catastrophic failure elsewhere. The last think I'd do is run out to Callies to have them build me a billet version just because I saw something...

@UpinBst Probably at this stage, no one can truly answer your questions. But, by the time it's been out a few years, like every other enthusiast site, you'll get 100 different opinions for every failure! In my mind, the engine is definitely if not state of the art, at least close, and Ford has...

I think if you look at 3 row suvs in the same category, you won't see much different in terms of engine development or drivetrains. Land Rover, Audi SQ7, BMW X7, MB GLS, Durango Hellcat. Most of these start (or need to optioned enginewise) to beat the ST and are $25k to $75k more (and yes...
