Cost per HP gained? 0-60 reduction per HP?
 

Has anyone compiled the cost per HP (Total Cost $$$ divided by HP gained)?

How about reduction in 0-60 mph? Say you gained 20HP, how many fraction of a second did we gain/lose?

Good idea

Just something you might want to consider... Say that you have an intake and it adds 18whp, and then you have an exhaust that adds another 8whp on top of the 18whp. But say if you did the exhaust first, the dyno would register 20whp and downplays the intake to 6whp. So you might want to consider that when you calculate the whole cost per HP gained. So doing a total price divided by total whp might make more sense than doing individual piece calculation. Hopefully this makes sense... Unless im talking complete B.S., just ignore my post.

Yep

That's what I am pursuing. Total as opposed to individual

at the end of the day, what is important to me would be the 0-60 reduction.

wgaf about 0-60 times....:wtf2:

100lbs loss for every 0.5sec improvement... typically.

There are plenty of calculators on the web to determine performance Vs HP or weight. Do a search. You'll find that lots of $$ rarely makes a big difference (unless the dollars are in a bushel basket)...:tup:

And a better diet would probably get people the most gains in this respect...

:ughdance:

yes, and it would be free too. :rofl2:

Are you kidding? Have you seen the cost of eating healthy these days?! :roflpuke2:

Who said "healthy" just dont eat and only drink. And Im not talking watter either. Or you could always go on a drug diet and stay skinny that way but the the cost per hp would go sky high.

touche :tup:

i think 0-60 times are meant more for magazine entertainment than anything else. i can think of a hundred different, better ways to calculate value per dollar, and sinking $$ into a car is not one of them, hehe!

to each his own. I have friends that spend money in ways I never would and they wouldnt spend money on things I do.

totally right, to each his own.

Actually a lot closer to .1 sec per 100 lbs in the power weight range.

Online calculator:

I think he was talking about quarter mile performance... which is certainly more relevant lol

Not according to the title of the thread. :D Plus, the quarter mile number diff is also far closer to .1 than .5 sec. Here, try it for yourself.

This thread is asinine and retarded. /thread

:) :happydance:

For some of us, we would like to know what other benefits we get IN ADDITION TO additional horsepower.

i give this thread a one and her asinine!

Yes, and that's reasonable, except it's not exactly a deterministic outcome.

It's so unpredictable, that it's not even funny.

Point in case. My 550 WHP FWD piece of junk could only pull a 4.3 sec 0-60 in its prime, even with impeccable driving. It's hard to predict 0-60 performance.

Besides, if you actually line up two cars that run relatively disparate 0-60 times (let's say 5 sec 0-60 vs. 6 sec 0-60), the distance that separates them really isn't that great or even noticeable until you hit higher speeds.

absolutely. the difference, visually, between a civic and a civic si is minimal, just like the difference between a 370z and a gtr is minimal. only after a distance greater than that covered up to 60 mph will there be a distinct difference.

With all due respect, and I didn't mean to be funny:

Say I buy a bone stock Z, I put a twin turbo, raising the HP to say 500hp, with all $8000+ upgrades, what tangible and measurable benefits do I tell to justify my expenditures?

tangible, well, if you get a thrill out of racing/speed/acceleration/noise/etc than that is the "tangible" gain. There is little more than that really. Many do it for respect, many do it for pleasure or as a hobby. Only you can answer why you do it, or want to do it.

x2

Personally, since I insist on working on and tuning my own cars exclusively, it is the sense of accomplishment after going from power level A to power level B on my own effort and skill alone. That's the only reason dyno numbers even matter to me (well, unless I happen to be setting a record :bowrofl:).

Track times are nice to track your progress as well. Definitely a good before and after, and they can definitely net you some bragging rights.

But the biggest component for me is the adrenaline-pumping experience that ensues when you press the loud pedal on your project car. And the noise... ah yes.

the sound of my car amazes me every time i drive it, and i dont expect that to change anytime soon! thats one of the biggest reasons i mod my cars.

yah, i posted wrong. i meant to type 0.1sec per 100lbs... not 0.5sec.

200lbs is not going to net you 1full sec of improvement. lol that would be too easy for them. :icon17:

If it did, I'd finally have enough real motivation to shrink down my big fat ***!

you and me both.

LETS just get down to the QUESTION!!!
 

Ok, The Million $$ question SIMPLY stated!!! Lets name the BEST bang for your buck in order!!!!!! 1-10. What are the CHEAPEST things we can do to our Z to gain HP!!!

diet

sell it and buy a camaro ss...:confused:

Some guesses:

1. K&N Drop-ins $80/5HP = $16 / HP
2. Berk HFC $550/15HP = $36.66 / HP

might as well get the base vette and get way more power for the same engine

or this!
