The intercooler is a restriction: plane and simple, just like a valve guide is to an overhead valve cylinder head, it's there, and it impedes flow.
If all you want is mass in your combustion chambers why not use H20 ![[Wink]](wink.gif)
given that pressure drops across an intercooler, and you are attempting to increase airmass the most, I will have to refer you to an important theory:
the 2nd law of thermodynamics.
It tells me that in this closed system, you will not get 'work' for free--- read increased air mass/charge etc. by passing your airstream through some convoluted tubing under pressure.
In fact I guarantee you the highest air mass possible is by letting PV=nRT do it's thing and heat the air.
The gain you get is driveability under high temp situations and low octane gas. It's a no-brainer mod, but don't try to tell me you've defeated the 2nd law of thermodynamics.
An intercooler is a passive device--- it will take away energy (read airflow) period.

Alright....You're over my head now.
I think I'll stick with my low boost/cool air power adder setup for now. ![[Big Grin]](biggrin.gif)

This post whoring shit happened the last time I posted and I missed out. I get all of your points and they all make sense but the the end of this thread which is what I just reached I have one person saying intercooler means more power and one person saying intercooler means less power. Instead of power increases or decreases, how about this- Its over 100 degrees outside, will an intercooler help shit out or not? I dont care about power at this point. I got more than I expected when I built the motor. Now I just dont want it to break after spending 15k. Thanks

Definately.
A GOOD air to air, Bar/fin intercooler can lower the compressor temps to 15 degrees above ambient at peak compressor efficiency.

before i ran my cobra at the track, i would have said someone was full of crap if they claimed a 79 HP increase with a power pipe!
seems to me that if you look closely at the answers, you will notice the folks with superchargers/turbochargers seem to agree.

Aww shucks, I missed the fun ![[Frown]](frown.gif) ![[Razz]](tongue.gif)
Last302- A wise man suggested you drop your base timing 1-3 degrees "for safety" and enjoy your 5.O ![[Smile]](smile.gif)
Oh yeah, not going WOT on hot days or after long drives (heat soaked motor and fuel pumps) wouldn't hurt either.

Sawson- Like I said, I finally have a motor that is turn key, a/c, like out the door brand new showroom 542 hp car. I freakin love it!!! As of now and even last summer when it was hot out I did not have any timing issues. With the chip as you are well aware of I have the distributor at base 10 and have it advanced through the chip with the 4 way switch. Even before the tune from Byron it ran great and after the dyno tune it was even better. No problems at all to speak of I just am looking for the complete setup to make this sucker, well complete. I guess the next question is does anyone know of somewhere or brand that makes a setup for my year(95) cause I cant seem to find anyone(vortech) or am I going to be going the full custom route? Thanks you guys, what would I do without you?
BTW- she dont be likin the heat in the summer anyway so I try to keep her inside till the sun goes down but I am the kind of person that wants to know everything is copastetic!!!

Don- 466rwhp so I believe that equates to about 542 at the fly depending on whos calculation you use. Hows things going? Your Back ok now?

Scott - My back feels better than it EVER has before. Seriously. It is incredible. If I knew the difference was going to be this good and quick I would have done it while in school.
