First, if you are going to build a truck for racing, why would you not start with the lightest weight chassis you can get? Most of these talked about are loaded up king ranch crew cab trucks, why push that extra thousand pounds around? These kind of trucks are why a strippie cost 25k. Some one has to subsidise those people haulers. If a 5k# truck will run 12's, a 4k# hopped up the same way should run low to mid 10's. Now ya got a real truck. Same thing with that diesel at Bonneville, those crew cabs are not light, take all of that weight out and watch it go...

 

It totally depends on what type of racing you would do....

 

Racing to the bottom of a lake maybe..

 

OK 1K of concrete

 

My 'normal' go fast mods with cars/trucks is to strip them out.
I've pulled stock carpet out of cars that had enough dirt and crud embedded that I needed help to throw it in a dumpster.

My old mustang weighed 3200 lbs when I bought it, after stripping it, swapping engine/transmission and installing a 6 point cage, it tipped the scales at 2880.
Other mustangs of the same year,with the same general build that had the original interiors simply couldn't touch it on the strip or street. (but then I also modified the firewall so I could move the engine back 6 inches for better weight balance....)

So yes, lightweight is the way to go!

The old saying is that losing 100lbs is the same as adding 10 horses, don't know how accurate that ratio is, but less weight does require less horsepower to get moving.

 

Just get a bull mastiff and and leave it alone in the car while you go shopping for a couple of hours... Come back; kick the dog out; shovel out the carnage; problem solved...

 

And that has WHAT to do with the TOPIC?

 

2014 Ram 1500 5.7 hemi, single cab. Very fast truck, 400hp stock.

 

I remove my tailgate when I wanna go fast, that's what 150 pounds?

Whooweeee!
