aye... though, at low-mid lift they flowed a lot less than PI heads; so for any cams close to stock the PIs would have still been ahead... the major problem with the non-pi's was the exhaust port/valves; if i'm not mistaking the PIs exhaust valves are 1mm bigger. some of the HP gain from the PI heads also came from shorter intake runners and cams though; which seem to be quite popular with non-pi guys nowadays.

long gone are the days for cheap mods for my mustang though...

It is under the rangers capacity. 2 jet skis are probably below the rating of the escape...

There was a 5100 lb Lincoln inside this 3800 lb trailer. This is what a SuperDuty does best...and yes, that is a 2V 6.8L V-10 with the 4R100 tranny.

Comparing toyos 1/2 tons vs 3/4 and 1 ton domestics. OMG toyo doing better than our gas and diesels. We have to admited DOHC marauder is right. When toyo comes with their heavy duty diesel, everybody hide because nothing will be left of our domestics. On october I was on my way home pulling my 35 ft 5th trailer. Next to me there was a tundra pulling a real big TT. We were doing around 70 mph and seems the tundra to be powerful. I couldn't left her behind. To be a 1/2 ton and a gas engine I was was amaized how she keep the speed flat land and some hills. I think our domestics 1/2 tons will never compete in power with these dawm trucks.

I read this in the dental chair yesterday.

Ridiculous comparison. In fact with all trucks not towing the same load, its NOT a comparison. Obviously, the diesel would do better with 7K vs 10K but I would like to see HOW MUCH better, then Id know whether to get a diesel next time or not..

Furthermore, saying they couldn't test 1 truck because it had no hitch is very unprofessional. Take it back and get one with a hitch, dumb@ss! Or put one on, its not brain surgery.

Why do they even bother including both chevy and gm? Aren't they identical in all meaningful ways?

Good to see another 6.8l.

The 4R100 is a little sloppy in stock form but with a tuner or a valve body mod it firms up nicley.



Of course a heavier SD with a beefier drivetrain, 2 less gears and 70 less hp will be out accelerated by a lighter more powerful half ton like the Tundra.

The SD is made to tow and be safer doing so with the SD over the tundra or F-150 for that matter. I get tired of guys comparing a Toy to the SD, sort of like comparing an F-250 SD to F-650.

Ok, i am not trying to fan the horsepower flames. A respected member at the mach1 registry made a comment about the new numbers on the f150. he is saying that he made some great numbers during the testing of this truck. He also came back on later saying that the new truck was making better numbers than a lightning and that it was doing it without f.i. http://mach1registry.org/forums/showthread.php?t=75862

Have you? These cars need to be shifted well above the HP peak. I suggest you take a look at this calculator. I see you hav winPEP, take your data exports and input the values into the calculator. That calculator has been very useful for many racers. You can argue it all you want, but it's mathematically correct.

http://www.camaroz28.com/calcs/shifter.html

mid range is 3000-4000 or 2500-4500, since rev range is 1000-6000, take the middle 1000-2000 rpm. Again, the car makes no useable power after 6200 rpm

Here's one of my earlier dynos, stock intake'd mach:

The rev range is 1000 - 7000 rpm, not 6000.

My own dyno sheet: stock runner length intake, stock cams, stock heads, stock longblock.



RWTQ peak at ~4950 rpm, RWHP peak at ~6150, plenty of useable power after 6200 rpm. What was that about a 3,300 rpm torque peak Fosters? Your graph is showing a ~4300 rpm TQ peak.

You might want to rethink your stance on the 13" runner length being the root of your high rpm power problems. Like I've already said, with the correct cams the stock 13" runner length intake will support a 6300-6400 rpm HP peak. A set of camshafts with duration in the 220 degree (@ .050") range on the intake side with a 114 LC will provide that. Once again, fact, not theory.

I don't have notes written on all of em about shift points, but I can guarantee you that if I took my car out and shifted where you think it shifts best, i probably wouldn't even hit 12s. I've tried pretty much every shifting point there is out there... 6700 ain't it, trust me.

See the calculator.

I thought you said the navigator heads are some of the worst? at low lift they flow the most of any head, save for FR500 heads; at higher lift they don't, true, but a truck head doesn't need that anyway. sounds to me like what they were meant for, trucks, they do a good job.

They are the worst by far. Less flow with a larger intake port (184cc vs 177cc for Cobras vs 160cc for FR500s). Have you ever seen a Navigator intake port? Ever notice the shelf that exists around the divider?

and I know what a flow sheet looks like, have you actually read one?

here's an example:

Wow, you have a subscription to MM&FF. I'm impressed. BTW, that is not what a flow chart looks like.

Funny, why is the long runner in the aviator intake just 13" long then?

They aren't. Aviator short runners are 9.25" long, long runners are well longer than 13". I just fed 15" of tape into the Aviator long runners (yes, I have one on hand) and there was still more to go.

yep, just what trucks need, less torque below 3000rpm and hp increase over 5000 rpm. you sir win the Darwin award.

Like most of my information, it appears to have gone totally over your head. The 99-01 cams will act like a smaller profile on a 5.4, displacement tends to have that effect. 184 degrees (@.050") is hardly enough duration for a 4.6, much less a 5.4. 4Vs respond very favorably to duration increases, .400"+ lift isn't as paramount. Being the 4V guru you seem to think you are, you should know that... right?

[4x4boss]

The guy on mach1 said it made more HP than a lightning....Well the last lightning made 380HP so I think they were testing the 6.2 because I dont think ford could get 380HP out of the 5.4 we have now. And it sure is funny that all the magazines are saying 310HP..........

About 10% of what you payed for your toyo goes back into our economy. The rest goes to the japs. Nobody wants to buy american anymore, but then noone can understand why are dollar is sliding, and our economy sucks. The big three pays union wages toyo doesn't. The union is the difference between $31 or $15 for me. If we as a country don't start buying are own products than we are going to be in alot more trouble than we are now. If we keep letting foreign economys come in and out sell us, then more and more of us are going to be out of a job, and with the mexicans take up the rest of the jobs we are all going to be up the creek. Were is that going to leave you probably dont care, because you as an individual don't make a difference. Well, everyone can make a diiference. Sorry about your transmission they can't all be winners. Also let us not forget this is a ford forum. The bigging brand is having alot of problems. It is still the ugliest truck on the road and will continue to be as long as the japs are designing them. I am ford fan for life, but i would rather see someone buy a dodge over a toyo, because it is american.

and where is this HD Tundra?

they only released a hideous concept

First; I have heard a leyend of a 6.2 Boss or hurricane. We don't even know the name. Onestly I havent read that FORD confirms when will start to offer this new engine. In the event some day we could really see it in one of our trucks. Only magazine rumors.
Second; HD Tundra! January/February 2008 vol. 11 no 1 page26 says on sale.......Don't hold your breath. Maybe by special order ,or soon start production. I dont know. Any way I think toyo wont delay a long time when we will see a HD tundra.

Well since this thread is already so far off topic I'll bite. Toyota pays a very fair wage for the job done. 31 dollars an hour is 65k a year. The same salary that an experience engineer gets. Someone with either a bachelors degree or a masters. Is that a fair wage?

Again in my opinion, 15 dollars an hour is very fair for unskilled labor. Part of the problem is the numbers are artificially high because of the unions. Now everyone thinks that is a fair wage. But once put into perspective its easy to see how inflated it has become

The dollar is in the toilet for many many reasons. I'm not sure that imported vehicles are the reason.

Its not our patriotic duty to buy american. It is our job as workers to build, design, sell etc the best product in the world. The reason that ford, dodge and GM are struggeling is because they chose to make and sell a lower quality vehicle.

I am in the same industry as you. I work very hard to design and test so we make the best product in the world. That way anyone would have to be stupid to buy another product. If everyone in the industry worked like that, we would not be having this discussion.

I will buy the best vehicle that is made today. Last year that led me to decide on the F150. Next time it could be a toyota, Honda, Ford, GM, hyundai, ANYONE. These american companies do not show loyalty to me, it is certainly not my duty to show loyalty to them.

it says that it is a "one-off to fantasize about"

the 6.2L Boss is a lot more real than this...

plus their engine does not even match the competitions'

oh and it is called the Boss, pictures of it in hotrod magazine

How can you be so mis-informed????

There is around 10% of profit in the sticker
That the U.S. Dealer made.....that leaves the 90%.

So basically Toyota makes the truck for free?

None of that 90% went to the U.S. workers?

None went to the American built Motor?

None went to the American built transmission.

Of the 75% American content, there is no profit???

And why are you so concerned over the profits of a publicly
traded company??

Isn't where the profits go more important?

If Toy takes the profits and builds a factory here while Ford takes
their profits(??) to build in China.....that doesn't bother you???

Fairly certain GM and Toy were neck and neck with Ford not too far behind.
It's not the volume of cars being sold, it's the mismanagement that hurts the domestics.

[on a purely personal note, it bugs me when someone plays the "American" card but doesn't have the respect to capitalize America]

And how much do Mexicans that assemble GM's and Fords make??

First off, when Toy, Nissan, Hyundai, BMW etc....come to a town, they are
creating jobs in that town. Jobs that otherwise would not have been there.

When GM/Ford move assembly to Mexico or import foreign cars to sell as
a Chevy or Ford, how many American workers does that help?

When Ford takes all that leveraged money to build factories in India and
China, how does that help the American worker?

Nope, they can't....but it sure would have been nice if Ford treated one of
their most loyal customers(over 25 Fords since '81) with some respect.
Instead, they made me jump through hoops on a 2nd trans that was a
couple days out of warranty.

Be advised, mis-info was written concerning the Toy.....if you want to live
with your head in the sand, more power to you.

You are 100% correct. Except for the flimsy tailgate, Toy has handled
the problems in a way Ford could only dream of. (BTW, my truck has had
0 defects)

100% your opinion....I personally think the '08 Super Duty is the ugliest
truck ever with the Chevy a close 2nd. Ironically, I thing the GMC is the
best looking truck, mostly because it looks like the old Super Duty.
Bottom line, subjective feelings cannot be argued.....

BTW, as per your usual mis-info, the Tundra was designed in California
by CALTY...a design studio employing AMERICAN workers. (not by "japs"
.....which is a derogatory term in case you didn't know)

I still like Fords.....just thought the Tundra was a better 1/2 ton in '07.

Actually like the Denali a LOT.....just a few more features on the Tundra tipped the scales.......Long road trip with sister's Mark LT took the Ford
out of the running early for ME.

Interesting comment concering Dodge....Not only are they built in Mexico,
up until Daimler sold them a few months ago, they were a German company.

I wonder if he'll get that???

[B's FX4]

yeah i agree with the guy above when time to come buy a new vechile ill buy whatever is the best product, like were looking at the escape/crv/rav 4 right now and ill tell ya now the escape is so far behind honda and toyota we crossed it off the list for a small suv choice, so i guess im the problem of why the american dollar in the ceramic! the big 3 is in serious doo doo

[fruth04]

hey B's you have over looked a few things, for the record my mother owned an 04 escape 3.0 4x4 and just traded for a new rav4 v6 4x4, the escape has a way more comfortable interior, 50times better stereo and 4wheel drive that works ( the toyota darts all over the road on icy conditions, and wont lock in when u push lock, and toyota says thats what it is spose to do) needless to say she is going to keep the rav4 but does admitt it is lacking on alot of qualities. alright...(back to the topic)
