well good for you and your slow k5, i will be using this as an all around daily truck for towing and driving to work and having fun on the weekends so power is something i would like to have. My slow k5 will be there when i need to go through mud, snow, water and up hills where those "fast trucks" cant go.
dont blame trucks for people driving like ****, i see mini vans and preluds do the same thing. going "quicker" as you put it is due to the fact that maybe some people cant afford a corvette and a truck so i would like to have the truck that can get as close to both as possible for my needs.
Same could be said for why do you need all that power in a sports car? no roads out there have a high enough speed limit to let you enjoy every ounch of power coming from that motor, but there is a lot you can do between 0-75 that can always put a smile on your face.
Driving slow and taking it easy is fine when i have had a rough day or just feel like being a sunday driver but 90% of the time i like to feel the truck launch and look over at the mustang next to me falling behind because in the end it just makes me feel good.
but all that aside if we are going to get into debate of "well why do you need a quicker truck"
Quicker means more power to weight ratio depending on the vehicle.
Quicker means that more power if not 100% of it is being transmitted to the real wheels on my command.
why is that important?
Quicker means that when im coming down the off ramp, i actually am getting up to speed like i should be and not holding up traffic
Quicker means that when towing i can get my load moving faster due to the fact that all things working together (engine power,transimission and gearing) are allowing me to.
Quicker means that if i feel like taking it to the local drag strip and entering it in the stock compedition i can maybe get down the strip "QUICKER" than the truck next to me. (yes they do have truck drags even though its not a sports car)
In the end being quicker has a lot more to do with just being stupid and cutting in and out of traffic like all the PU truck drivers in texas do
its more of the question of why is a stock ford quicker than a stock chevy for the same price and which one should i go with because being quicker than the competion's brand plays a big part in who im gonna give my money to, along with the other parts of the truck.
Lastly you can never have to much horsepower. even if its not a sports car
