Just 87. There’s no recommendation for 91 either. Try one out - I have a feeling you’ll like it!

It’s not irrational, it’s common sense. I realize you are severely lacking in that department, but try to mull on it a bit. If 10 cars are going 80 in the same direction it is a smooth flow. If 9 cars are going 80 and 1 jackass is going 55, 9 other cars have to take maneuvers to avoid the jackass. It doesn’t take an engineering degree (although I have 2...) to understand this concept.

It will pull about mid 18s to 19 flat... it definitely drinks when it is working. It’s quiet aside from some turbo whistle and a bit of exhaust growl when it pops out of 8 on steep inclines.

People who don’t go with the flow of traffic create a larger hazard. I see it every day. I’m not sure where you live, but I presume it isn’t a major metropolitan area, let alone one of the most challenging areas to drive in in the US, as I do. Im glad you’re proud of your 97 cubic inches that you have over me. There is a replacement for displacement - It’s called forced induction. Why don’t you go start a 4.3 liter fan club thread?

I’m in the DC metro area. The speed limit on most of I-270 and the beltway is 55, average speeds are in the 70-75 range. My cruise was set on 83 this morning going with traffic on the toll road (speed limit 60). Obviously I was driving to get to work and not to save wear and tear on the fuel gauge. I see people in the left lane get passed on the left shoulder at least once a month. Trying to drive like Grumpy does around here will get you killed.

Praise Jesus... someone else saying it besides me.

It’s also horribly unrealistic advice. Driving like that where I live will incite rage at best and get you run off the road at worst. My time is worth more than money. The funny thing is that fuel economy was about #5 in my reasons for ordering the 2.7... not really a consideration, more of a fringe benefit.

Only it's not really applicable in this case. People need to know the subject they are discussing. We're not talking a small 2.0L engine being pushed to its limits here (looking at you, Volvo XC90...). It's a large bore, long stroke truck engine that is putting out a relatively low amount of HP for its displacement (in terms of boosted 4 cylinders). It is overbuilt for what it is, and it's set up to work like a diesel - pulling from low revs, and it doesn't need/like to be wound out (it redlines at 5,700 RPM - I've personally never had mine pass 5,000 before shifting). It would be a terrible flop in something like a Camaro or a car based SUV. It's a purpose built truck engine with a character that suits a truck -

23.1 this morning when I got to work. Best I have seen over 400 was 23.4 but that was on a road trip with a combination of flat and mountain driving and I was pushing low 70s much of the way. Like any turbo - if you get heavy handed with it, it guzzles gas - but it does seem to be very responsive to a light foot returning good numbers. I tend to be a bit of a hypermiler - coasting down to lights and using the pulse glade technique on flat highways when I am not in cruise. I live in the DC Metro - so my driving consists of a lot of stop and go in heavy traffic, and a lot of rather aggressive highway. My 2.5 liter Colorado with a tune, manual transmission and 4.10 rear struggled to get out of the upper teens overall and regularly would get 12-13 around town, so this is a much more relaxed and welcome improvement.

I'll believe a 4.3 getting 27+ MPG when I see it.

2,800 miles in so far. Averaging 23.1MPG, best of 25.9 over 25 miles. Tows my 4,100lb boat like it isn't back there at all - particularly through the Blue Ridge mountains in Western MD. I couldn't be happier so far. After about 800 miles, the engine note changed a bit and is more of a low grumble most of the time. I find it pleasant to hear when you do (when it is cold it is loud, however), but it doesn't enjoy being pushed past 4,500 RPM, and really does not need to be often at all. It needs the 10 speed behind it though... whoever let the 8 speed out the door with the shift logic that it has needs taken out and shot.

And your purpose posting in a section for 1/2 tons is?

I’m completely fine in my choices. This thread is quite obviously titled to be a positive discussion about the 2.7. Your posts have added no value to the thread.

Great! I’m glad you know what you like. I need to find that 5.3 or 6.2 fan club thread so I can go post in it now about how they are thirsty and outdated. Wait, I’ll have the respect of not doing that...

Ah ok. So you haven’t driven one. Point made. I’ve got 2 other turbos sitting in my garage - one of which is known for its lag. Twin turbo is not the only solution to lag - dual volute is working quite well with this engine. Again, I’ve driven it, I’m not going on outdated ideas here. Had the boat behind it earlier actually, bringing it home for some fun tomorrow. Not a bit different than going down the road unloaded. The boys at TFL didn’t have any noticeable lag when running fully loaded either. It’s a pretty legit tool considering it pulled the Ike at its limit in the same time that the 6.2 did at its limit. Sounds pretty well matched to the truck to me. The 3.6 sounds like garbage and pulls like garbage. It’s nowhere near the same class as this... I’ve owned one of them as well.
