I was just thinking about this with regards to weight and horsepower. If you race a car that is 1000 pounds heavier than yours but they have twice the horsepower would they still blow you away? Or just by a few car lengths?

 

What horsepowers and what weights?

 

Car 1:
3600 lbs
300 hp

Car 2:
2600 lbs
150 hp

 

Car 1 probably.

 

Just go on the highway...

 

You'll lose.

 

Don't quote me but I believe I read that 10 lbs. was equal to roughly 1 horsepower. As in, dropping 10 lbs. was like gaining 1 HP. Of course I could be smoking crack. I am in no way an expert.

Try to find the other part to this. They are doing a 1/4 race and you can see that the heavier Ford wins.

 

The power to weight ratio is better on car 1,

here this will help

Car 1 wins hands down.

I've seen 200-220hp 1700lb car beat a 3800lb 400hp car

All motor K20 CRX vs GTO from a 20 roll

A 1500-1800lb car with 215 hp can run 11's all night with good tires.



Excuse my rambling but power to weight ratio has entrigued me for years.

Drop 700+ lbs and car B might keep up.

 

Car 1 would win.

 

This is no brainer I,ve seen 1000hp supra get spank by 200hp bike. Now dothe math.

 

Car 1, 12 lbs per hp,
car 2, 17 lbs per hp...

This doesnt take in considerations the gearing, trans, hp and trq curves--nothing, so while car 1 certainly has the advantage it could be car 2 is much more fun to drive..

Need to consider more then what your looking at.

 

Good way to mask the typical: Will my Lancer beat a ____ thread

 

Horsepower will take over once you hit about 100-110ish mph in a roll race. Gearing is big too, but its a big variable, so forget it lol.

I had my buds 777whp supra up to 140mph by 1 car, once we both shifted to 5th he was starting to come back pretty hard on me. He would have been back even with me by 150.

I know thats an extreme example and much higher than I stated MPH wise, but I made 710whp and he made 777. His car is 600lbs heavier than me. If he had been shifting as quickly as I was he would have been able to pull me in a little faster. I had an instant car jump on him and we stayed a car apart til 135-140.

Long gears and more HP up top will win a roll race.
