Its a 4x4 F150 2V 4.6... Those heads are going to hold you back big time, The mustang guys are about 420-440whp @8-10psi and that is tapped out on a 2V motor... Your a truck with 4x4 so 375whp is about right, a 5.4 2V or 4.6 4V is what is going to make power...

And your right you cant win when your doing it through a stock intake and stock truck cam. You are losing alot of flow and power right there.

 

damn shame

 

its going to be a little while till i find that much money to get the truck back but i will put more specifics on here when i get them..... but yes a 1998 f150 4.6 built to a 5.0 with a cam 1 level above stock, 5.4 natural gas heads and stock intake it would not make power above 5250 rpms and 12.75#s boost and he said like 18 degrees timing with meth. i will get a pick of the graph when i get it. it is a nice arc but not as high as i expected. i test drove it today and seemed to pull not bad but not 7k worth
oh and 4r70w tranny, stock tire 235/70/16, stock rear end gears 3.55s

 

what kind of dyno?

 

I don't know much about Ford motors so I'm in here to learn!
Silver-mado might be helpful since he's a ford mechanic.

 

it is a dyno jet i beleive the guy said that these are real world numbers and that numbers arnt everything. the curves do look good and smooth and arched nice and said that it "cleared the dyno in 6 secounds in 3rd gear" lol now that is nice but i no the truck sure as hell wount do that kind of pull on the street.

 

Did the dyno jet have the eddy current brake on it? If not, that could be the low numbers.

 

there is some kind of brake on it but i dont no if he used it during the pulls.. he did use the brake while he was getting it to learn or getting the sencers to do there thing.

 

Note to self: stay thell HELL away from 2v 4.6s

 

shoot twin turbo v6 makes more power LOL
