CFM flow rate of spearco replicas...

[starscream5000]

Hey Aaron (or anyone who knows), how many CFMs the normal spearco replica rated at? And what is the Bigger version rated at?

The smaller one is around 800 cfm, it has a 3.5" core. The larger one is a 3" core, so even though it is wider, I don't think it would flow more air then the smaller one. I have the smaller one on my car.

Thanks Aaron, that's exatcly what I was wanting to hear! I was looking for an intercooler that flowed about 800 CFMs, so the 800 is the exact spearco replica right? And the longer one flows a little more even though it's half an inch thinner because the overal dimensions are larger right?

Edit:: I also had few other questions: What type of cores do they use? Are they like the spearco cores where they are straight through bar and plate style? Do you have pressure drop numbers for each IC and efficiency ratings?

Thanks for replying to my many questions I seem to have about something that most people don't take the time to consider ;).

These are both bar and plate style. Now while the larger intercooler might offer better cooling, I really don't think it will flow more. This is because the overall area of the core that air is passing through is about the same.

Gotcha ;).

800cfm huh.... what is the most hp you would run through our intercoolers? (i have the smaller one)

[bigaaron]

I'm running close around 475 crank hp through one right now.

Do you have the bigger IC in stock ATM? I'm undecided on what to buy next for my car: The full DIY bigger IC kit you have, or the increasingly hard to find RS-R GTII exhaust that 935 has in stock...

[bigaaron]

They are still on back order. The thing about the "bigger" ones is that they are a 3" core, where as the "smaller" one is a 3.5" core. So the actual area that the air flows through is only about 5% more on the bigger ic.

Eh, I think I'll hold onto my $$ for now and wait for the bigger one to come in, I like the fact that it is longer and more air hits it ;).
