What if we had two cars set up like this...
Car A:
- 875 lbs total weight, with fuel
- 600 hp
- decent suspension with decent tires
Car B:
- 2700 lbs total weight, with fuel
- 1000 hp
- decent suspension with decent tires
How do you suppose the two vehicles would compare, performance wise?
Assuming whatever vehicle you had could get proper traction, power to weight ratio kind of favors the vehicle that is less than 1/3 the weight, with almost 2/3's the horsepower.
875 lbs with 600 rear wheel horsepower calculates to 6.6056 ET, 206.34 MPH
2700lbs with 1000 rear wheel horsepower calculates to 8.1111 ET, 168.04 MPH.
I guess you are comparing a bike against a race car?
**** your results may vary, don't try this at home
What if the two vehicles in question here are boats. Boat A could be 600 hp outboard and boat B could be a 1000 hp stern drive.
How would the performance compare then?

One boat would likely outperform the other.

Based on the composites of both hulls & the given density of the air quality at appox 3' from the water, I am going to have to say the Blown injected jet would kick ass!!!!!!!!!!!!! :crossx:

Maybe you can help me with this question, Maxi.
If I have two boats:
Boat A - can do 8 second 1/4 mile runs
Boat B - can do 10 second 1/4 mile runs
... if boat B has a better induction system and more power, which boat would be able to do the quarter mile in less time?

While not a BGJ I will attempt to answer your question.
first you must have a plan.
I've run the numbers Tom and it appears the Plan A boat will always beat the Plan B boat. However in my calculating I also determined that if the B boat could do 8 seconds in 1/4 mile runs, the 2 boats would be equal in time. But given the A boat would be cheaper to build because of a lesser induction system it is also likely lighter, such a boat would be more desireable than the plan B type boat. This would be especially true in rural areas where basic substanance wheat farming was the main livelihood of boat buyers and Maximas are the tow vehicle of choice.

If a constipated bear can run 35 mph and a constipated deer can run 40 mph which will be the first to eat two nine inch bran muffuins? :rolleyes: :p

DUHHH!!! Come on Tom... these are preschool questions dude! Everybody knows that Plan B would kick ass... :rolleyes:

How come it just occurred to me that nobody in here gives a shit about power to weight or performance theory of any kind. :idea:
It seems to me, a 2700 lb boat is going to have one hell of a time keeping up with a 900 lb boat in linear acceleration or turning. It might be competitive at sheer speed as that's more of an aero and hydrodynamic issue but the extra weight is a significant detriment to speed too.
It's not a slam on stern drive boats to say they are at a performance disadvantage when compared to outboards. It's just the physics of power and weight.
... but I think I'll just pipe down and let big gay Jesus throw some more commandments onto the fire.

That would depend completely on the size of each animal. I do believe the bear would like have an edge though because he'd probably kill the deer before it could finish the 2 nine inchers thus winning by eating the deer and the remaining muffin portions.

You know... as the moderator shouldn't you be a little more educational??? This line of posting should be left to the professionals! The bear would obviously munch the shit out of the dears muffins & then possible finish off the deer! Given! Now why is tom so interested in trying to make sense??? Is there a 24hr flu running around the Canatards arena??? I don't see kImmy posting a bunch of scientific shit??? :rolleyes:

Kim is busy doing top secret research for the Labatt people.

lets not forget powerband..
if the 600hp boat has to spin 9000rpm ,makes almost nopower below 5000 rpm and only makes 300ftlbs of torque and the 1000hp boat spins 5000rpm,makes power almost from idle and makes 1500ftlbs of torque it would be one hell of a race ,,that is if the 600hp boat could get on plane.
As important as torque and powerband is to a boat especially when
you talk about drag racing or heavier boats I am amazed noone ever
talks about anything except hp.

Sorry jesus I'll back off and let you animal pros take over.
I haven't seen Kimmy posting too much on the scientific side. I think the Labatts may have damaged that side of his brain or something.

It works because you set the prop to slip a bit to work similar to a stall converter.
The heavy boat has to have all that torque to pick it up out of that big hole in the water.

Do you suppose it's the 'all that matters is torque' guys who hate outboards so much? :D
It must be upsetting to be proven wrong on a minute by minute basis.
If all that mattered really was torque, I would put a 50000:1 gear reduction in my pedal boat, create 100000 ft*lbs of torque with my legs, and kick the ass of every big block jet on the water. Of course... since the load is dynamic, torque is only relevant to an engine's ability to do work when also taking RPM into consideration. Torque with respect to RPM would be... horsepower.
Hey... where's steelcomp when I'm spewing some good shit? He needs to learn this stuff.

But since you apparently sit down to pee, it's something that you are not familiar with. :220v:
