jon_the_limey Posted April 8, 2009 Share Posted April 8, 2009 400 lbft on a naturally aspirated 5 litre gives a BMEP of 13.6 Bar. Not a chance! Especially on a truck V8 with a cross-plane crankshaft and just port injection running on regular! Not even the BMW V10 M5 engine gets much more than 13 Bar BMEP and that runs on premium and doesn't have the charge robbing that crossplane V8s have. 12.5 Bar BMEP for such an engine would be exceptional and that gives a torque of very nearly 370 lbft. Hurricane with 2 Valves and 6.2 litres natually aspirated would be doing very well with 12 Bar BMEP and therefore 437 lbft. Boosted is a whole different story.

I reported this some time ago on a boosted 6.2 as a Diesel alternative. Surley you must have recalled that. Quote Link to comment Share on other sites More sharing options...

Understanding a mechanical concept is one thing, but applying that knowledge to solve complex mechanical problems is something entirely different.

Shit, most people in here can't provide an idea unless they've read it somewhere first. Take a breather. Most people in here, actually purchase vehicles, Something within their budget.. That may sound foreign to you, but it seemed to work for a lot of people. The ones that Rent/Lease are always wanting something to be just a little more than they could actually afford comfortably. A concept people seemed to have lost in the last 20 years. This overseas bullshit of kids right out of H.S. talking about the next BMW they are going to get is so far out of reality. it's amazing..

Good post Jon, I know you speak from experience with J/LR and others. Quite impressive the money J/LR spent developing their 5.0 and they still couldn't get to 400 lbft.

silvrsvt Posted April 8, 2009 Share Posted April 8, 2009 (edited) The 400 lb/ft 5.0 Coyote is boosted. Perhaps you missed that. I'm lost, I though Coyote was the code name for a special direct injection 5L V8 engine with turbocharging that was similar to a diesel engine that used menthol injection? I've also heard it called the code name for the naturally aspirated 5L V8 thats going into the the 2011 Mustang, and the new Mustang was supposed to put out 400HP and the same amount of Torque?

old_fairmont_wagon Posted April 8, 2009 Share Posted April 8, 2009 Well, as long as the 5.0L in the F-150 has more torque on regular gas than the existing 5.4L, and also produces HP numbers that are more competitive with its competitors (assuming that any survive) then it will be a success. Since the 5.4L produces 365ish lbs of torque, I am hoping that the coyote is in the 370-375 range. I know that that's likely wishful thinking and that it'll be pushing it to make it to 365. Still, if can achieve that and be more efficient and lighter than the 5.4L, at least progress was made somewhere. Now, looking at a boosted 5.0L V8, in this day and age, I'm not quite as impressed with 400 lbs of torque. However, and here's the rub, given what we've seen of the torque curves on the other EB engines that have been released, if they are getting that 400 lbs at 1600 rpm and carrying it all the way through 6000 rpm, then that's an entirely different ballgame.

blksn8k2 Posted April 8, 2009 Share Posted April 8, 2009 This is the first I have seen any mention of the coyote 5.0 being boosted. Is this a larger application of Ecoboost with DI and turbos or is it supercharged a la GT500? Either way, 400 ft lb sounds pretty anemic in this day and age when even the 1.5L smaller 3.5L EB is putting out what appears to be an electronically limited 350 ft lb. Maybe I missed something here but are we talking about 4V heads or is this a smaller displacement version of the 6.2L with 2V heads? Something sounds a bit fishy to me... :shades: Quote Link to comment Share on other sites More sharing options...

I said months ago 400hp, and 365 lb ft in NA form. My source is very reliable, so I'm sticking with that prediction. :yup: I have no idea what Blue II is referring to.

jpd80 Posted April 8, 2009 Share Posted April 8, 2009 A 5.0 Mustang with 400hp and 365 lb ft will indeed be an impressive car and I suspect many a V8 Camaro owner will be sorry they ever laid eyes on it. Quote Link to comment Share on other sites More sharing options...
