I am running very, very close to my buddies Hemi right now, with intake, exhaust, and superchips 87 tune but he also has 33's. I wanted to get to the track this year but couldn't make it because it is 2.5hours away.
18 flat , my 2004 with 300 horse and 3 73 stock tires went 17.30 @79
Really?? That seems a bit slow to me. My 97 4.2L "bone stock" with 3.08 gears ran best ET of 18.02 @ 78 mph on 255/70r16 AT tires and that was with the spare tire in the bed along with about 25lbs of other junk. I know my truck has nowhere near 300 HP so I would imagine your truck should be a lot faster. I'm not knocking you or anything it just that the numbers seem odd to me compared to my truck.
I raced my 2007 F-150 XLT Supercab 4X4 5.4 3.55 Gears
down the 1/4 mile 5 times.The truck is all stock from the factory air filter to factory exhaust.The worst Et was a 16.858 at 81.769 mph and the best was a 16.653 at 83.231 mph.The Dodge's with the Hemi aren't much faster Car&Driver April 2007 Dodge 1500 4X4 Quad Cab with Hemi and 3.90 gears 16.2at 86 mph,Ford F-150 4X4 Supercrew with 5.4 and 3.73 gears 16.7 at 83 mph.
the famed HEMI's lose power now as dodgee in an effort to get cheaper only put the HEMI Heads on with out the HEMI pistons and they loose compression!!! dodge and there short cuts for money. also this has been stated alot fords numbers in the book=Flywheel. im hoping to get my truck dynoed soon. 97 f-150 4x2 book says 210 added K&N 77 pacesetter shortys no cat true duel dynomax super turbos and E-fans. any one wanna stab at what i should be making close to? *for HP i dont know the loss in power and all that kind of stuff* also what would i run? i have dunlap radial rovers 265/70/R16 the back tires are a lil low on air and they grip right away on the street. but if they have the right amount of air my truck churps the tires. Also does preloading really help that much?
kinda sad but oh well i dont have the time or money to do anything that cannot be done in a weekend. all those mods stacked up gave me some good gas mileage thoe. started at 10 MPG with stock everything and im around about 16MPG in the city. so they've paid for them selfs...cant wait till next weekend when me and Jbrew go at it.
