Google... your best friend.

There are tons of 1/4mi estimators on the www. a few allow you to put in other variables to make it more accurate: altitude, reaction time, etc.

Your car runs the quarter mile likely slower than stock since you put those downdraft Webers on there. Go back to the SU carbs or swap on fuel injection. You can't quickly make up 2 seconds of time with weight reduction or a tune-up. You might be able to swap in a lower geared differential and hope his car isn't tuned up well.
Borrow someone's 240Z that has a Chevy 350 in it. Done deal.

Unless you start cutting metal, it's about as light as it's going to get. ~2400lbs is already freaking light. Take out the passenger seat, and all accessories, and you might save 40lbs, which won't make your car 3 seconds faster.
There is no McDonalds cheap way to make a lot of hp.

yeh i kinda figured it would be near impossible to loss much weight. i dont no if this is probably a bad idea but i was thinking of making a custom hood for it to where the is a small scoopwhere it feeds right to the carbs. and get a k and n filter. i figured people say it adds like 15 hp for a filter some it would more likely be 10-8 hp and with a forced induction thats cool air it add 30-40 hp a grand total of 40 to 50 hp bolt on. later maybe once i have enough money up grade the exhaust to even out the induction and exhuast.

Let me say this the nice way:
Apparently you have no concept of how an engine works, nor how hp is calculated / created. If everyone could get 50hp+ by mickey-mousing engines, we'd all be flying time machines right now.

240 diet meal plan
as some might know im going to drag racing a buddy in the begining of summer and in need to make my 240z about 200 to 300 lighter. i know it is near impossible with the z's but how can i cut the car's weight while keeping it functional as an everyday driver. i dont care about sound proofing i like the noise.... some any and all advice is welcome.

Merged threads... no need for two threads talking about the same thing. And I swear you saw this:
If you want a 2100lb 240z, cut the roof off, remove headlights, tail lights, seats (yep... you can sit on a milk crate), carpet, fenders, cowl, all glass, all non-important nuts and bolts, and might as well cut out the floor boards while you are at it. Then get some light weight aluminum wheels...
Oh... and put yourself on a diet (fat driver = slow). No more McDonalds.

dude ur every where. do you know how much the sound proofing weighs that the one thing i know im going to do. ill tell u when i do it. i was also thinking about taki g out the extra wheel well if it was possible, just cut it out and weld it flat. he cant be right bout that 2 horse power thing though. because you are freeing up the air and forcing it in the chamber creating a denser air and fuel mixer. and that would be the reason for the exestance of turbo chargers.
but this would be a much small scale. because instead of get its air for underneath the hood its get nice cold being pushed in by the areodynamics of the car. it would be the begining of a total engine build up. but i live in illinois and there aren't very many 240's here like in cali. where there are a ton of junkers to pick at. ill also have to upgrade the spark plug and ignition system too, with the exhuast.

What the? Seriously? You act like 2400lbs is the heaviest car ever... WHAT FAT? THERE IS NO FAT ON A 240Z.
If I offered you one million dollars, would you say "pft... I want two million or nothing!" ???
Some people are never satisfied.

no i meant its either have it where it like 2200 and it be only a racer or keep it like it is because it already is light. but i just need to add more horse power. because buying some extra tires that would increase grip and stuff

a 90 gt stock running 14.6? are you sure about that? if he actually pulled those times at the track and that's not just an estimate then his car isn't stock. it should be a good half a second or more slower than that...
and you'll never be faster than your car already is unless you up the compression. or do what i did, stick a turbo motor in the car and up the boost to a little bit closer to 10lbs and then your car will be in the 13's for around 600 dollars. easy.
