air densitity which I think humidity plays a small role in that. I don't really know, but I think so.

 

Ok well i've only had my Stang for about a month now but i have a perfect feel for the car, i drive it everyday. Today was about 78 degrees, 0% humidity, sunny... the works. And i SWEAR my car was faster it pulled real hard in 1st all the way up to 5400 or so then i shifted into 2nd and wham! she really jetted off... am i just imagining this or does humidity really contribute to performance... i kno temp does but its usually no less than 50% humidity in Indy during the summer.

yea i live up in MA and the summers here are usually pretty humid, but on those crisp, cool summer days the car seems to run better. could be in my head but im pretty sure weather can make a differnce

Air density plays a large part in how an internal combustion engine performs. I'm far too out of practice to properly explain it, but you can google it and find out the proper explanation. Basically, the more volume of air/fuel you can get in a cylinder, the better the possibility of a more powerful flame front. Which is why we supercharge/turbocharge engines. Humidity affects **** as well. A nice, cool charge of air vaporizes better & thus burns more completely. Which is why we intercool stuff.

 

Yeah that is the exact reason I run 16s when I should be low 14s!

ahhh good man... be upkeepin your research lol. That does make sense though. So let me get this straight. Whenever you add forced induction, should u always add a better fuel pump and injectors, i look at everyone's mods and thats usually the case... and an intercooler is like a radiator for the forced air.. (i mean i already knew that just makin sure).

 

Yes exactly. You nailed it manic.

better fuel pump and injectors helps you not starve your engine of fuel so you can get that perfect mix of air and fuel. Or as close to it as possible. Think of it this way.

More boost means more air.
More air means you need more fuel.

Most everything that is stock is restrictive.

Thats how I think of it.

 

Word.

 

thats very true... well right now intake wise i'm running a 75mm TB and Plenum but with the stock Intake (i know i'm stupid). I'm planning on buying a K&N CAI, u kno the one thats black plastic and the heat shield facing the engine block... What kind of hp gains will i see with this? and with the gains will i actually feel it?

BTW later on and i mean LATER, like 2 yrs or so... i'm planning on a KB 1.6L... how much do those run for for a complete kit w/o install... also would 9psi be alright, like under the 400rwhp limit.
