I was reading and look at some interesting facts i found:


here are some good information i gathered from various magazines on making power and dropping weight in your car...this is only a rule of thumb, and is to not be mistaken for exact numbers, because all cars are different

1. A 10% drop in the temperature going into your motor will result in a 1% horsepower gain

2. For every 1000 lb. drop in a car will result in 1 second off your quarter mile (I don't know if this is true in imports, because i got this info. out of a hot rod magazine)

3. For every 10 lb. drop in a car will result in a 1 horsepower gain (This doesn't exactly mean 1 horsepower gain to your motor but you will feel a 1 horsepower gain on your 1320 dash, or 10 horsepower faster with 100 lb. drop)

1. I can believe this.

2. I think it's less than 1000lbs in my opinion...something closer to 600 give or take.

3. I think this is just restating 2. since motors don't gain hp when the car drops weight it's just that they pull that weight more efficiently.

good info

i also agree with the info... and re: the 1000lb weight reduction equalling 1 sec faster 1/4 mile. prob less then 1k lbs due to the fact that most imports are already lighter than most domestics (the info is from a domestic magazine)

thanks for sharing the info....

very interesting information... something to think about

deftones0817

will 100lbs is 1/10 of a sec so that kinda makes since...
10 lbs = 1 hp well just figure this and you'll be doing good.

weight / hp = how many pounds you are pulling per hp (did i say that right) so basically you lower that and you will have a better power to weight ratio i think a civic is around 20lbs or per hp and a 1999 mustang saleen is like 6 per hp...atleast that is what i got from a site. hope that helps.

I think that is a little off. A mustang at 3300lbs would put out 550 hp. Does the saleen make that much HP?

deftones0817

a 99 mustang saleen the super charger one not the na one makes 490 hp. So roughly that is correct...maybe be off by a pound. That **** is hella fast my friend has one and the specs i looked up say 490.

yea..that's why it's critical that you watch what you put in your car if your concerned with keeping the weight of ur car to a minimal

all makes sense to me.

A rod unbalanced 4oz puts force of over 400lbs on the crank at 7500 rpm.

1 lbs of unsprung weight = 10 lbs off sprung weight. (1lbs lighter flywheel is like takin 10 lbs off your car.)

AzntaggeR

that is also useful information

Imagine if all 4 rods were unbalanced 4 oz.

I'm gunna go on a diet, lose 20 lbs, and I will get as much horsepower gain as intake. W00T!

redcxhatch

Major problem with V8's, you can gain like 30-40hp buy balancing bottom end. I wish i could get the same results from my 1.5!

joe_bocc

It's sad that the V8's come that unbalanced!
