i know what the engine HP is.. but when it gets to the wheels it is less. duh

ok but seriously have you guys noticed speed from stripping the seats.. trunk.. passanger seat.. etc.

so many talk about it. but on our cars does it really do squat?

its just changes the power to weight ratio of the car so ur engine has less work to do not as much wieght to pull.

think of your engine as muscles.... would you have an easier time lifting a 100lb box or 10 lb box?

Nice way of putting
But come on does this really need to be discussed, it is common sense

I cant wait to pull out my subs.trunk floor/spare/and a bunch of other stuff. I always like having subs though, so i dont care about weight. Only when I hit up the track hopefully in about a week. Gonna see what times I get and how noticeable 2-300 lbs is, probably pretty noticeable. Like when you have 2 people in the car, your car will lag a lot more, and if its a fat person, damn our car is slow. I hate boosting with way fat people in the car, lol. They also make me bottom out, haha, for reals though.

i think he was asking more like this:

'if i go to the trouble to reduce weight, will the performance gains be noticable/worth it?'

of course it has an effect, but how much? i mean, can you feel the speed/acceleration difference, for instance, if you remove the back seat/door panels/whatever?

edit: after rereading the top, his thread title is totally different from what he eventually gets around to asking, so i can see why y'all be explainin' and ****.

I would say, if the race track is where your car will spend the majority of its time then yes it's worth it, but if the car is driven for daily driver keep your carpet ,back seat, stereo, etc. IMO its getto too if you don't have a fast car to start off with.

Agreed, unless I was running 11s, I would keep my full interior. Than I would only rip it out to get the times down. Its better off to be comfortable, and not damage any parts lyeing around the house and not be able to reuse it to sell it. Unless its a 400whp civic, and you dont drive it daily, go for it. Otherwise, leave that ish in.

Its really not hard to pull out everything for a track run. Just do it the day you plan to run.

unless you are going to take out EVERYTHING unnecessary, as in door panels, metal door frame, dash, interior carpets, panels, seats, metal console frame, rear deck, spare tire, etc. then you probably wont notice the difference. If you get the car down to a layer of sheet metal on a frame then yeah the like 500+ pounds should make a pretty decent difference.

U can really notice when u take out interior, i took out 200 lbs from my crx and noticed alot better acceleration and a lot better freeway passing power. the rule of thumb is for every 100 lbs u take out of a car, u gain .1 second in the 1/4 mile. and .1 is quiet a bit if u know about track times.
