Have a good friend that was talking about his 12sec Mercedes E55 AMG, I was like oh really lets go for a right in a 1.8L 4cyl I have, long story short he would not stop talking about my car for the rest of the night. He could not belive it....lol

 

Hahaha, it would have been awesome to have a dash cam capture his reaction!

 

Even I admit, I'm interested in some in-car video on the street or course again. No more dyno videos. Let's see this thing rock. I'm so proud *sniffle* *sniffle*.

 

Was just thinking. At what RPM range do you feel that full pressure of 19psi is being felt now with the new intercooler? (Are you retuning yet, as I know you're about 5-8% leaner now than with the older I/C.) I'm just noting this kind of feedback in my records.

 

Would you say that using a larger intercooler allows the Turbo to operate at a higher efficiency then using the smaller intercooler?

So in other words say "X" Turbo becomes inefficent at 20psi. Would upgrading to a larger intercooler raise the efficiency level to say 23 psi (just an example) Since the intercooler should do a better job off cooling the intake charge when it reaches the ineffecent boost levels?

Just curious what youre insight is?

5-8% leaner from just a intercooler upgrade seems as though it has a significantly better cooling effect

 

But if IAT's have been tuned correctly then there should no difference right ?

 

haha Im glad Im not the only Paranoid one

haha I love doing that to buddys of mine they have never been in a built boosted car and think their WRX's or their 2010 Civic si's are fast then they take a seat in this 4dr grocery getter and are like OMG! gotta love boost! congrats on the build

 

That's exactly the point, hence my animated drawing. Remember, an intercooler is nothing but a large heat exchanger. Ingested air from the turbocharger becomes heated as it compresses and goes down into the the turbo outlet to the intercooler. If the intercooler is a more efficient design. (sometimes, larger is enough for it to be that way), it will have a better ability to cool that charge pressurized air as it goes through the louvered fins. This then "exchanges" the hotter air into colder air, so that it is much cooler as it enters into the combustion chamber. the fact that it is more dense air makes the car a little lean (not too much) but should still be retuned ever so slightly to make sure its not too much.

The problem is if you go TOO big or too thick, the pressure drop that the intercooler acts on the entire system will cause the turbocharger to not be as responsive, and it takes another 2 psi to get the same power as you had before. In this case, Calidad is fine as this one isn't too thick.

 

Great info! your a wise man!

 

seems like it comes on at about 4500 RPM

 

You mean full pressure of 19psi by 4500 rpms, correct?
Just making sure your clear. Ok..

 

more like 23psi by 4500

 

On a simple 1797cc, that's pretty damn good.


MUahahahaah

 

You need to change your name from TheShodan to TheHouse haha

 

 

 

Lol, FUNNY ! This boost and crack is killing me . Now i wonder who done the comparison test ? ? ?

 

If you could. Give me a bit more breakdown of the rpm range for the amount of pressure that's being run. Since you're running on AEM, I'm sure you can have Bisi, (or yourself, depending upon your proficiency with the software) as to an rpm/boost pressure extrapolated curve that can be saved on an Excel file. I've had done before, but I'd like to get more feedback data on what you're experiencing, as well as your impressions as you drive the car with the larger intercooler.

Please also PM the file if you happen to create one.

 

teg looks great, i hope my coupe comes out that good. big kudos man

 

Are you referring to my boost per gear chart?

 

Thanks!!

 

Not concerned about gear so much. I'm looking at 4th gear and engine load for boost/ rpm curve for one gear

 

Cali dad are you able to data log?

 

Of course!

 

Had too too add my two cents for the motivational poster's lol
