Re: Subtle-Solutions Intercooler Splitter = Good Stuff!!
The only ways to prove whether this works, would be to put'er in a wind tunnel with a clear hood and watch where the smoke goes, or to install multiple RTD's placed along the top and bottom of the IC and monitor temps at varying conditions.
Having a buddy in the trunk of the car in front of you letting loose a few cans of spray paint might work, too. The more color on more of the intercooler, the better!
