cp-e DeltaCore FMIC intercooler validation paper...

[www.cp-e.com]

Since you don't mind the questions I do have another. The pictures show square end-tanks with a taper. Why did you not triangulate the tanks? An example of this is the general shape of the stock tanks.

This could easily increase the efficiency by 5-10%. You could have the added benefit of radii in the sheet metal from bends and lower standard work hours. It is easier and faster to bend metal than weld it. (there still would be some welding, just much less of it)

Although rounded corners are always beneficial when dealing with fluid flow, I'd argue that the decrease in pressure drop along the core wouldn't be worth the effort considering how we fabricate these end tanks. Although you're right that there'd be less weld time, cutting and bending the odd shape required would be really difficult for us. I guess you'd have to come by and see how we fabricate these things to really understand. In fact, you're more than welcome to do so! We love visitors (2thumbs)

Now, we plan on casting our end-tanks at some point down the line. Since you can cast just about any closed shape imaginable, we would absolutely consider optimizing the design of the end-tanks to achieve lower pressure drop. You're probably right in that a triangular design would be more efficient, but at this point we've found a great compromise between fabrication time and functionality.

And speaking of which, I also forgot to mention that there is a baffle inside of the end tank to better distribute the air across the length of the (long) intercooler core. I'll try to snap a picture of that tomorrow.

I have a question about the piping.

This is the first time I've ever seen a FMIC with the bumper and stuff removed, and I have to say that it seems kinda counter productive to have the piping right below the air intake. This would heat that whole area under the fender and make the intake charge even hotter....wouldn't it?

I looked through the Validation report and even at a cold start the turbo outlet temp is 167F. After running hard it will be over 200F and that will heat that whole area, after the bumper and fender liner are reinstalled that area becomes fairly boxed in.

I wonder if cutting the area behing the fog light and adding a mesh material there wouldn't help things out even more??

Ah, I see what you mean and that's a great point actually. I guess my response to that would be: You can have it one of two ways....

Couple an aluminum heat sink (your top mount intercooler) on top of an engine running at 200F, or expose the air filter to a section of piping carrying a finite amount of 200F air. Both cases will heat the air to some degree, but I'd argue that the filter over the hot and cold pipes is the lesser of the two evils. But you would be doing yourself a service by creating more ventillation to that area. You're absolutely right.

Since the engine bay and surrounding area is so tight on the SPEED6, there aren't many viable places to route the pipes. So, we chose the best location we could. I think you'll come to find that future FMIC manufacturers will choose a similar route, just because there aren't many other options unless you want to start cutting body panels, which, most of our customers frown upon (wink)

I figured that cutting was the reason, I just wanted to make sure I wasn't thinking crazy....and I agree it is by far the lesser of two evils and I'm starting to save my pennies as we speak. (first)

I'm thrilled to hear it!

I think you'll be more than satisfied

where is the MAF sensor?

 

[Chris-BE]

where is the MAF sensor?

On the intake.

(wink) Baffle, good idea. I thought there might be some reverse flow through the first few rows because of the bend at the upper end tank (and without any slope to the inlet side of the tank doesn't help), but that probably occurred to you guys as well.

 

[Rican219]

So where is the BOV going?

 

[buit9110]

On the intake.

obviously on the intake but I don't see where in the intake they put it.

 

[MS6mike]

it is going to be before the intercooler, right where the old top mount sits

 

[Chris-BE]

obviously on the intake but I don't see where in the intake they put it.

It's the same place it's always been on their intake, just after the filter.

This has nothing to do with the FMIC.

Weird question.

And I will see good benefit out of the FMIC and EMS upgrade. I will tune after the install, and should see the benefit from those freed up psi. The dyno will tell, but I'm shooting for 300 whp.

What is the verdict?

CPE hasn't got the FMIC pipes back from the powder coater just yet. I'm waiting to hear from them and then to install and tune. another week maybe? who knows.

What is the verdict?
