OH WOW!!!

This is TREMENDOUS Oreo!!!!!!!!

Thanks brotha!

 

anytime bud.

 

Not offense to oreo for posting a link to help, but i wouldnt buy a cheap cooler guys... kinda like building a sweet intake and leaving a rag over the filter. If you don't have good flow through your intercooler, then you will really have crap performance... cheap intercoolers are cheap because they aren't made well... just my $.02

 

Umm, I run a "ebay special" intercooler on my turbo'd mustang. Just because it doesn't cost a million bucks, doesn't mean it isn't any good. I've had zero problems with it, and running over 13psi though it the car made close to 500whp.

 

how much flow do you think you need? if it were for a 6.0,6.4 or 6.7 id say no way cause that needs so much boost. but our engines dont. its a n/a engine with a light turbo boost. those intercoolers will work just fine.

 

I have an ats turbo on my 6.9. Could I add an intercooler? I get max 8 psi boost now?
Thanks, Mike

 

ya, you can add an intercooler to anything. start by clocking your turbo up and moving your top had around

then get the sleeves and have an exhaust shop bend your pipes up OR get a universal kit and work that out

 

correct me if I'm wrong, I know I don't know everything... egt's in a gas motor top out around what... 600 deg.? And judging by your sig, im guessing that 5.0 is the mustang you're talking about that's turbo'd... so you have a 302CID motor to fill with air at a boost of 13 lbs with a turbo running at about half the temp that a diesel turbo runs. So you put an ebay cooler on a motor that's 2/3 the size, that operates at half the temperature, and a little lower pressure, and that's justification to throw it in my face?

The purpose of an intercooler, my friend, is to cool the intake air that has been heated by the turbo. The intercooler has to do this efficiently or else you will have your 15 psi of boost in the pre-cooler (hot) pipe, but the boost will drop way down on the after cooler (cold) pipe side because the cooler can't effectively flow that kind of air volume. A 7.3, need I remind you, is a 444CID motor, that's alot of space to fill for that dinky turbo. It is already pushing itself pretty hard to pull 15 psi once you turn your motor up, and then you take a crap intercooler and bog it down more. So, you save a couple bucks up front in not paying for the correct cooler, push your turbo too hard ALL of the time, either A: don't have proper boost at the intake manifold, or B: aren't properly cooling the intake air, so you basically put a wet rag into your intake system in hopes that it will boost your performance.

I'm sure that a little cheap-o cooler works fine on your stang because either you bought one that was big enough to accommodate your intake flow demand, or you bought a turbo that was alot bigger than you needed and you're actually overboosting on your hot pipe to compensate for the coolers inefficiency. I am also not saying that you have to go out and buy some one off or high dollar turbonetics or ATS cooler. I do all of my projects on a budget, I'm not rich. Ask James, I showed him how to build a proper intake for like $5 to replace the one that someone else told him was a good idea, guess what, it cured his problem. I'm not trying to have someone else talk him into buying something that's going to impede his truck instead of help it. You have to consider alot of factors when you're doing something like building an intake or sizing an intercooler, or filter, or building an exhaust, or anything!! flowrates have to either match or exceed what the motor is asking for, otherwise you're just setting yourself up for failure or mediocrity. I haven't steered you wrong yet, have I J?

 

boost psi means nothing really. its temp. right now lets say your boosting 15lbs of hot air. when the air is hot, its expanded so you need high numbers to get a level of o2 in your cylinder. as the charge cools the psi drops but the charge becomes more dense, there for being more o2 in a ci. 2lbs of 40 degree air is more effective then 20 lbs of 200 degree air. o2 molecules are a lot smaller then any liquid, a smaller intercooler is still going to allow plenty of cfm's to flow though it. big block chevy only needs a 10"x10" intercooler water to air.

 

Good point oreo, however pressure does matter because there is no way you're making 40° air through any cooler. I know it was just an example, but a really good intercooler would give you about 150° at the motor. So at 150°, you are looking at air density somewhere around sitting at idle on a hot day in phoenix... not real good, but a lot better than 3 or 500° from the turbo. So boost pressure drop is a very relevant and important factor.

As for the big block chevy, gas and diesel motors again, are very different. You can't really compare the two, even of similar displacement because gas burns with oxygen differently than diesel. Diesel is harder to ignite and harder to burn, diesel demands a lot more o2 because it has a greater power yeild, almost like saying it's like concentrated... see what im saying?and a water-air cooler is about 10 times as effective as an air to air, so again, not a direct or good comparison...

 

I'd say my cool side pre intake is 60 degrees or less. Even under the hood my charge pipe is cold to the touch. As cold as my a/c lines

 

Once the motor and turbo are heated? While you're pulling a trailer up a hill? Don't think so bud, unless you have some magic turbo technology that none of us know about. Im not trying to be a jerk, but when you blow 1200° gas through a metal housing, there is no way you are getting 60° air out the other half of it, it's not physically possible

 

after a 2 hour drive unloaded yep yep. cold to the touch. and where are you getting 1200 from? think about it... by the time the exhaust gets to the turbo your down 300 degrees, and your not feeding that exhaust to your engine, your turbo is sucking cool air, passing though a warm turbo and running though the intercooler. and thats peak heat. most people dont see over 900-1000 degrees under regular driving, thats 600 at the turbo, add an intercooler then your dropping your egts more there by creating a cooler charge. see the cycle?

 

First of all, I want to thank Oreo and Brian for your posts. And a very very very special to Oreo for posting those pics for me. Pretty friggin awesome yo. I havent met Oreo yet, but dude absolutely knows his *****, and has helped me ALOT so far!!!!

I am very fortuneate to live close to Powerstoked. Sometimes Brian (Powerstroke) blows me away with how CRAZY SMART he is. OH, and of course Fidy Diesel in Concord Ca.

and second of all, Oreo and Brian, you two mother *****ers are just WAY too smart for me!! HAHAHAHAHA!!!!

BOTH of you are absolutely correct here. I just need to score a cooler from either a 6 or 7.3, thats all. The problem is that those stockers are pretty difficult to come by

 

I guess the idi's might run a bunch cooler. With my 97 calicode powerstroke, it's pretty easy to hit 1200 when you're making the motor work. But then again, i have my truck chipped and piped... fair enough to say that we're both right? I have my experience and apparently yours is different, which definitely happens. I actually have been thinking about getting an idi so i can learn more about them too. And i have actually load tested a diesel motor and shot the turbo with an ir temp sensor and seen the turbo housing over 1100°. So they can and do get way smoking hot when you work the motor
