That’s why those of us who use the stock IC run 3 chamber shrouds that pull air from the side scoops. The rooftop scoop just isn’t that efficient.

@Me! Thanks for the link, I hadn’t realized there had been 35 pages of discussion on intercooler flow rates already. It was nice to see that my quite crude relative pressure measurement (mm H2O) data lined up with the flow (CFM) reasonably well, in particular the CFM data also linearly increases with speed. Taking an airsaw or dremel to the lip on the intake behind the roof is surprisingly effective in increasing flow rate.
It’s cool that your data is similar to the previous study! I also really like your T-top!
