Figured one of you horsepower junkies in here could answer this question.

What is the weight savings to horsepower gains calculation?

 

this might answer your questions.

I believe each 100 lbs in weight reduction is equal to adding 10 hp and can reduce your et's about 1 tenth. Loose 500 lb's and you should be able to drop 1/2 second from your time.

 

What are some of the easy ways to reduce weight to a stock vehicle? Are there any?

 

I think replacing the stock seats with GT3's are the easiest way to start...

 

The GT3 seats and light wheels.

 

Anyone know if my SSR's are lighter than the stock wheels? They came on the car when I bought it so I didn't see any original specs. If it matters they are the 18's.

 

It depends on what HP and weight you're running stock.

On a 3000 lb car with 100hp, you're at 30 lbs per hp. That means you need to save 30 lbs to equal 1 hp.

On a 3400 lb car with 415 hp, you're at 8.2 lbs per hp.

 

And note that the real effects of lightening is more palpable
than a horsepower figure. If you say you have a '415 hp' car,
the fact is that even at the drag strip, your car is developing
415 hp at about half a second of the run at best. 95% of the
time your car is at a different RPM, producing significantly
less power. Your car is, however, the same weight at all times,
so the real effect of weight loss is as if your torque curve was
raised across the board. Weight loss is *better* than a power
adder because power adders can add lag, or lower the torque
in some places to get more in others etc.
Lightening moving parts is doubly beneficial. The wheels should
be the first step.

PS: Just for interest, mathematically, if a 3000 lb. car can put
down a constant 200hp to the ground for an entire quarter-mile
run, it's a 9-second car.

 

Kevin,

go through the weight loss thread and pick what you like. there is an "easy" 150 pounds to shed.

 

We could all probably reduce our body fat % and = 5lb-15lb or more.
Just an idea...only in the name of health and speed

 

That actually is very real and a great idea for all it may apply to.

I would rather (as an MD of course) see someone loose 10 pounds of unneeded weight rather than buy a lighter battery!!

I weight 160 compared to racing someone who weights 220, think about it me and my car are 60 pounds lighter!!!!

 

How about 2400 pounds and 220 hp? I think I can drop off another 200 pounds no problem. Guess that puts me at 10.9 pounds per hp.

So if I lost another 200 pounds, It would feel like I gained another 30 hp?

 

At that point, it's a rough 10.9 lbs per hp. Drop 200 lbs and it's like increasing 18 hp. It'll always be off a bit, especially as you make bigger weight or hp changes.

Again, as Joe Weinstein pointed out, these are only approximate numbers. There's more to the story.

 

I tell this to KPG all the time!!! Lay off those burgers!!
