What is the magical ibs/hp number?
 
What is the magical lbs/hp number?

For simplicity reasons...lets say that spending a $100 can get you either 100 lbs off your car OR add 100hp to it.

This gives us the equation: $ = H = I or numerically: $1 = 1hp = 1lb.

I think most of us would choose the 100 hp in that scenario.

My question is at what starting value of L would it be make more sense to choose the weight saving instead of the hp?

For example, if the equation instead was the following: $ = H = 100*L
then most of us would opt for the weight savings instead of the power.

So, starting at what value of L would that start happening?

Thanks:D

Uh... 100hp for $100, compared to just losing 100 lbs?

I'm going to be in the long line...

Um...I just wanted to mention that the abbreviation for "pounds" is spelled with an "L" and not an "I".

$1/hp?! Sign me up? Seriously though, expect to spend $75-$100/hp. A lot of weight shedding is free, if you're hardcore and/or bold enough. Stuff like rear seats and spare tire removal are free.

The rule is to 10lbs/1hp..not 1:1 So a 290hp 2900lb car was just as fast as a 300hp 3000lb car.

But that is in a straight line..the lighter car will (usually) handle and brake better.

And only up to a certain speed. Typically, the 2900 lb car would get off the line quicker but be slower than the 3000 lb car as speeds increase. It becomes more of an hp / drag issue than hp / weight.

I used the "made-up" 1:1:1 ratio to simplify things. Since I am hoping someone would enlighten me and give me answers along the lines of what you answered.

I have slightly confused myself at this point...so I removed the rest of what I was initially commenting...

:clap:

I had forgotten about drag and how it came in play.
Thanks. Any other insight on this subject?
