More intercooler discussion here. I searched and could not find any discussion on this topic so here is my thread.

We (my builder and I) are thinking of doing twin IC's instead of a single for a few reasons.

-to be a little different than most
-for an aesthetically pleasing look (to me)
-to line up with the air vents in the lower valance I want to run

Now, this is what I could not find anything on. Is there a disadvantage to this except maybe a little added cost? I see some ProCharger kits (I saw a C5 kit) use twin IC's. Is this is less efficient than running a larger single IC? Maybe the C5 kit used them out of necessity and less space under the hood?

Any insight is appreciated. FYI, I have the ProCharger D1SC.

The more bends, interruptions and turns, the less efficient your set up will be.

I can guarantee you the 2x set ups are that way because the single IC (needed to cool the volume of air) would be too big to fit in the space given.


If its a street car, then I wouldn't worry about it. A race car is a completely different story.

Twins will be fine. We are doing twins on the 67 Corvette we are doing with a ProCharged ZO6 motor. A lot of recent cars run twins, it is much cleaner packaging. And you do not interfere with your A/C efficiency, your hood latch, ambient temp through the radiator, to name a few.

I have a set of ATI twins for sale pretty cheap if you want them, Complete with plumbing and all.

Like mentioned, they are great on a street car, or any car with less then 800 hp or so. They are very efficient for the small size.

A single will be more efficent if you can fit it. There have been a few tests done on twin to single conversions like those found on the C5 stuff with big improvements.

Part of this also depends on application. If your not pushing the system real hard, they are still a viable option.

Nitro... I have about 750-800 hp so that might be the ticket. I sent you a PM back over at lateral-G.


Everyone else... thanks for the comments and insight. Sounds like I will be fine with the twins since it is a street car.
