Cool...good info. Anyone know weight of a 2000 SCAB 4.2? Or where I can find it?

 

I dunno if im dumb or what but a 4.2 will not beat a 5.4 given the 5.4 is the exact same model as teh 4.2 ie same cab,box,and if its 2wd or 4wd it doesn't add up to say a 4.2 spanked a 5.4. Why would anyone pay more for the 5.4 if its slower?

 

You just contridicted yourself. What the hell are you talkin about Willis?

 

Ok guys, 2 things.

first to answer Husky's question, my truck weighed in at 4600 pounds at the track. That's my 2003 supercab XLT fully loaded sport model. Your's is probably slightly lighter.

second, to answer inlines statement, when I was younger my 440 hemi roadrunner used to get beat by small block Chevy's, even though my big block had much much more horsepower. The weight of the engine slowed me down.

It also depends on whether or not your driving an automatic or a stick. Now, not on all occassions, but I have beaten 5.4's in a race before. They'll sit at the light and spin the heck out of their tires and I'll just take off ahead of them. remember, it's not how much horsepower your engine makes that's important, it's how much horsepower you lay down on the pavement that counts.

I would bet, if you put my auto truck on a dyno next to a stock auto 5.4 on a dyno, my rear wheel horsepower would actually be more. Perhaps the torque would not be more, but the horsepower would be.

Under certain conditions, my truck could beat a truck that had 4,000,000,000,000,000 horsepower at the crank. If he was running on p175/70/14's with an open diff.

Oh and to answer your question "why would anyone pay more if it's slower?". It's NOT slower, stock to stock comparison. But once you start modifying your motor, all bets are off.

I've seen 4 cylinder Chevy Chevettes pull 10's in the quarter mile....freakin sick. They tear out all the seats and put plastic window's in and huge tires in the back. And the thing is so freakin sick sounding (in a bad way) it almost makes you throw up when he takes off, but he beats corvettes, porches and vipers.

Ever seen a 10 second bug with wheelie bars? Hehe...pretty funny when he beats a 70 Charger with over 450HP I just didnt understand his question.

As for my own, I am wondering where I can find the exact weight of my truck. Then I can add my weight, and other BS like...stereo equip. I never got an owners manual, or I would have looked there first.

There is an easier way... Most DOT weighstations will let you drive across the scale and weigh your truck.

 

Base Curb Weight for 2000 model year
F-150 SuperCab SuperCrew
3,923 4,204 4,581

I know...i'm the man.

 

Oh, by the way, what else is "Inflatable Debbie" used for?????????

 

You can get all the specs on your truck by clicking the "Specs" icon in the upper right hand corner of this site.

p.s. Inflatable Debbie

 

Hehehe...I thought youd like her :*-(

 

So basically, if my base curb weight is 4,204, and my lard butt weighs 215, and I have 63 pounds of stereo equip. come race day, my truck, in theory, should weigh roughly 4482. Not counting the weight of my valence or tonn. cover. BUT, I could subtract some weight from the changed exhaust. That sound about right? So if I weigh....4450 even, just for math reasons, and I have roughly...235 HP, just for math reasons, I should anticipate a 1/4mi time of 15.57 at 87 MPH.

So then in theory, if I were bone stock, threw on that SC, that would give me about 285 HP. with the same weight, that would put me at 14.55.....

So If I can hit 300 HP, that would rock my socks!

I am going for longest post, trying to beat out Tom without a tangent!

 

damn, came up short ;-P

 

15.57...no offense but keep dreamin'

Not necessarily, but hopefully...you also have to take into account to torque balance as well as your tires...like spinning them because of all the power your just attained. With all that bs said, I think you are well on your way with the SC man! I commend you!

 

Commander Husky, with all do respect sir, nobody can beat my long posts : )

I don't know where your coming up with those numbers but you can't calculate your quarter times that way. It's not an exact science. There are too many variables in play.

First off, your not fat, your just big boned! I way 200 also and am 6'2". You can catch a picture of my ugly butt in my gallery.

Sencond, there is no way you can calculate the exact weight of your vehicle that way. There is, or should be, a scale at every track. Put it on the scale and see. Also, many speed shops have scales also. They'll prob charge you 10 bucks for a weigh in.

Third, what did you do with your Valance that your adding weight to your truck for. Don't those come stock?? The flat black plastic thing under your front bumper? Probably weighs 10 pounds.

Tonno cover weighs about 50. I have the Extang on mine. But that helps with aerodynamics alot. You can always take off your tailgate before you run, there's a hundred pounds right there.

Plus, you'll need practice at the starting grid. Taking your foot off the brake and applying gas just as your releasing the clutch is alot to do in the .499 seconds between the last yellow light and the green. The trick is to do it smoothly enough that you don't spin out, but slip the clutch just enough that your on the verge of spinning, but not quite. That takes practice. Ask Joseph.

That's why most Pro Stock racers are automatics. You get a much quicker and more accurate launch. That's where my torque converter will come into play. It will give me that "stick shift, popping the clutch" type response on the start. That's why they're 1,000 bucks.

Also, you cannot race with a passenger. So you'll have to stuff Debbie in the truck bed.

Again, a much longer post...he he he
