INTERCOOLED RAM AIR

BigPimpinRacing · Apr 14, 2004

Ok, I saw that a few of u guys were wondering what intercooled ram air is so i am fixin' to tell you! Intercooled ram air is basically just like a 5.0 Ram Air kit but with some mods! As you can see in this link, RAM AIR ,the Ram air box on a 5.0 is put under the car well on the 2.3L Intercooled ram air it is almost just like that except it has a bigger box and infront of the airbox is a heater core hooked up to a waker pump and tank running freezing cold water through it to cool the air going in the air box. On the street I just run reg. water in it, but when I race i put about 1/4 water and fill the rest of the tank up with ICE! I will try to get pics on here soon!

Seems like a lot of effort for a couple degrees of cooler air.

Its just not a couple of degrees!!! I first had just the Ram Air and i gained 10 rwhp and then i got the heater core and it was making a tenth to a tenth and a half quicker on the track and i was making 15 more rwhp than the stock Ram Air!!!! We measured the intake tems and it cool's it up to 15 degrees when a bag of ice is in there!!!! I would say its a GREAT UPGRADE and it is very cheap to make!!!!

You use an RV electric water pump right? I had an idea like that to, it all started when I dumped a bag of ice on my '72 Chevelle's intake, then took off: I could feel the power!
Thanks for the info, glad to see someone inventive has actually built one and seen a gain! You inspire me to pursue my own design!
Keep up that hotrodding spirit man!!!!!!!

so your saying 25rwhp difference total for the intercooled ram air intake. dude you must be smoking some serious ****, I think someone has been reading hp claimes on air filter boxes again. hell even 15rwhp is ludicrous. ESPECIALLY on a n/a 2.3l engine.

15 degrees below ambient ain't gonna make 15 hp, buddy.

were these #'s found on a dyno?

bhuff30 · Apr 15, 2004

assuming isobaric cooling of 15*F with an ambient temp of 86, you are gainning 3%. 3hp. Thats IF the core provides no restriction.

BigPimpinRacing · Apr 15, 2004

I WAS SAYING 25 HP FROM THE STOCK AIRBOX!!!!

actually I was thinking the other day of how an intercooled setup might be rigged up. You don't realize just how much power is being lost to the restrictive high temperature intake on these things.

of course I'm not gonna piss away effort on a 4 cyl though.

Not as much as one may think.

I would honestly say even if you had a way to freeze the intake you still may only see gains of a few horses at the wheels, even on a large engine.
Not really worth it IMHO.
Obviously throw some form of compressed air into the intake and you will see more gains since the air is being superheated from compression.

just buy and intercooler spray kit there like 250 and 10% hp gains on a stock turbo setup

Pro-Hawk · Apr 16, 2004

Rule of thumb: For every 10dgrees cooler the air intake gets you gain 1% Hp.

did you ad the 15hp gain that was written on the air filter box?

Brantley · Apr 16, 2004

I think I'll just turn my Gillis valve to the right a bit more.

Ray III · Apr 16, 2004

No you won't get 25hp sitting still with an intercooler. But it's not just the temp drop, if you had a ram air scoop enveloping the whole of the radiator air inlet that would result in a significant increase in volumetric efficiency at speed.

I guess it's just not true that a turbocharger adds 100hp.

BigPimpinRacing · Apr 16, 2004

They way i got it set up is i got a box about the size of the stock air box and it has an 3" inlet and outlet the oulet goes to the TB and the inlet goes to a K & N cone filter down in the fender well! and i was running it at the track and i picked up 2 tents and 25 hp at the wheels on the dyno!

bhuff30 · Apr 16, 2004

speed pressure increase
30 mph .02 psi
60mph .06 psi
100mph .2 psi

hmmm, at 100mph, you get .2 psi, which is approximatly a 1% increase in pressure... looks like the ram air gave you ~1 hp AT 100MPH!

by the way, all of these calculations are slightly high. they assume that the air comes to a complete stop, which it does not.

BigPimpinRacing · Apr 16, 2004

No offense, but all of you forumla freaks, some times things break the odds, a heater core is really more efficent than you thing and no bull**** i am making 25 at the wheels, my buddies stock s-10 4 cyclinder made 15 hp and 1.5 tenths at the track! People i am not making this up!

None taken

First law of living lol there is always an exception to the rule but its not the rule

Did you by chance take note of every little detail to make sure that something didn't change like the temp out side? Maybe his tires was 10psi less and was able to hook up more or maybe he drove better the last round. Mock the forumla freaks all you want but go down and see what others are using. I bet the competetion is listening to the math wizards and above all esle if it works for you run with it
