Latest 6.4 info

[mschn99]

Alright...between training and talking with an enganeer....ill share everything i know about the 6.4 to date. Please take into account in responce to this that all of this info is strait from either Ford training, Ford enganeers, or Ford publications that ive been given.

The first thing i wanted to point out is that according to a fact sheet given to me today.....the f-450/550 chassis trucks will actually have LESS horsepower and torque than the 250/350 chassis trucks. I dont exactly understand this and the enganeer i talked to had no answers for me. The heavier truck has 25 less HP and 50 less foot pounds of torque according to the published numbers on the sheet i was given.

Your coolant flushes have gone up in price...LOL. Total coolant capacity in the 6.4 is just a touch under 33 qts...YES...over 8 gallons. All but two quarts is for the main cooling system with those two quarts going in the fuel cooler.

DONT touch any wiring harnesses wrapped in orange conduate. These wires carry 200 volts or so to the injectors. There isnt enough amperage to kill you so you will just be wishing it had.

One of the most interesting things will be the fact that installing aftermarket exhaust on this truck will be a no no. There is basically a collection chamber on it that periodically has fuel injected into it (by injecting it during the exhaust stroke) to burn the carbon and particles collected in the canister. That whole process is all based on backpressure readings. There are also two exhaust monitors (basically O2 sensors) in the system. Messing with the exhaust WILL cause a check engine light according to everything ive been told of this system. Backpressure needs to be exactly in the stock configuration for any of this to work. This collection canister needs to be cleaned every 120k on average they figure....more so under certain conditions. Even if you live with the check engine light....there is a chance of ruining this "self cleaning oven" type canister as they call it. This canister when i asked about was refferred to as being extremely expensive. When i said "why is it really expensive"..the enganeer told me that it just is..and it is not really expensive..its EXTREMELY expensive. Also...im being told that smog is coming on these trucks and this motor WILL NOT be exempt from it. It will have to conform to current standards when smog hits in most states. It will never pass smog if you do an exhaust. This is just a warning going on info i have been told....

Ford claims it has 10 million on test trucks....they claim this motor will be solid....

the water in fuel sensor will be very sensitive and the actual seperator housing will need to be drained once a month.

Non ford fuel additives supposidly WILL cause injector failures

Standard diesel oil will not work in this motor...ford has a new oil that MUSt be used in it. That oil is compatable with any ford diesel..but the older oils can not be used....

Under conditions that MOST people on this forum use thier truck....oil change intervals will be 5k... (10k if it never sees idle time...city driving...dusty conditions or towing) and fuel filter will be 10k (20k for above conditions as well)

If i may add one thing. From what I have been told on the 450/550 lower hp ratings is the same method Ford has been using on the 650/750 to an extent. They have had lower hp ratings due to using some of IH's parameters that focus more on reliability and longevity then hp and performance.

I was told the only differencs in HP is a program, so it may be possible to load the F350 program into the F450. I have seen the order form and if you get the 4.30 gears instead of 4.88 it will have the higher HP from the factory. The COOLEST spec I have seen is that the 6.4 is a 390 cu. in. Ford has sent some of these to fleets for test and some already have over 300k on them and still going strong.

i think ill stick with the 6.0 after hearing that

With all these beepbeepbeepbeep govt regulations being put on the manufacturers we will all be riding our pedal bikes or walking someday

Hey..i could have let you find out yourself.... ....just reporting what i know

[sldghamr]

after hearing that, sounds like to much BS. an engine that is that sensitive to what people do is not worth having. i'll stick with my 7.3.

I remember picking up an old hot rod mag, I don't remember the title, but it was a 1982 issue, kinda like me an 82 issue . The article was about the end of making horsepower. The reasoning for the statement was because of this new electrical device called(wait for it) a ecu . I think anything new just needs a little time to be figured out by shadetree mechanics and aftermarket vendors to pull the kind of performance you want out of these trucks. Afterall it's because of the ecu you can plug a chip or downloader in and add around 100 HP in about 5 mins. Just give the vendors a chance and I'm sure there will still be an aftermarket for these new trucks. JMO

hmm, This truck was designed and built by people, it can be broken down and hot rodded by people too. Just give it some time.
