Weight??

[BlueWaffle]

Anyone with a similar set up (2005 FX4 CC SB) know what the curb weight of this truck is? I can guesstimate the adds for wheels, tires, etc but need factory curb weight. thanks...

I would guess that the factory curb weight of your truck was 7700-7900lbs.

Now, I bet its over 8,000 pretty easy. At least I know my 2000 ccsb lariat is and its a similar size.

ok...trying to calc my horsepower from some 1/8 runs last night.

Honestly using 7850 7950 is pretty realistic.

 

[BlueWaffle]

i just used 7800 and it calc'd out to 558 at the wheels...sounds like it might be a tad high but who knows.

 

[SIX_OHH]

Whats done to it injector and turbo size?

 

[Mpoage]

Mine with no spare and hardly anything in the truck with my bumper and me (210) weighs right at 7950.

190/100's and a powermax

Don't use ET to calculate. Use trap speed. Its usually more accurate.

 

[SIX_OHH]

558 is a modest number for that. My opinion.

 

[BlueWaffle]

Don't use ET to calculate. Use trap speed. Its usually more accurate.

Jap the calculator I used takes both et and mph. Not sure how an 1/8 mi calc stacks up to a 1/4 one but who knows. I'd like to make a 1/4 pass to compare the two

Wanna post the times?

I'm guessing 8.3

I'm guessing 8.3

nope...that's the weird part.

8.6 with a 1.9 60' @ only 78 mph. I could only launch at around 10 psi...any more and I pushed through the brakes. it was only my 4th pass with this setup but it was 105 degrees and I hot lapped 3 passes so I let it rest for a while...then started drinking so didn't race again. I know with a few more passes it'll get to the low 8's but I need better tires so I can cut a faster 60.

here's the hp calc I used...not sure how it came up with 558 but that's what it spit out. I think that number would be alot more realistic with a 8.3 like you said.
