Well, the Trick Flow R lower manifold is taller that the stock or GT-40 lower, so going to a stock type lower intake would shave about 2 inches off of the height. Also the custom outlet manifold from the supercharger could be trimmed down about 1/2" without to much disruption in airflow. The upper manifold that holds the intercooler core could also be trimmed or shortened a bit. Part of the reason for the tall cowl hood is that the throttle body is positioned facing up and when a air filter is installed for street driving, you end up with a tall hood. If you did not mind a longer path for the airflow, the throttle body could be relocated so that the overall height is lower. We were interested in MAXIMUM airflow. Thus this is how it ended up. The original design was under a Cervini hood that was much lower. But we found that the shorter the inlet path to the rear of the supercharger, the more boost and power we made, and since the car was being driven less and less on the street and more and more on the track the big cowl hood was not an issue. The current design is the 4th or 5th version and the one that promotes the most power. Being all custom, and having to farm out the aluminum welding, it has not been cheap, but it is worth it. Outside of the welding, all of the fab work and design work is ours. The hrs it took to map all of this out is crazy. Plus throw in dyno time, track time ect and it is no wonder it took 4 years to get to where we are. NOBODY sells this stuff. Hell, that is what makes it cool, and that is part of the reason we did not go turbo or ProCharger, we wanted it to be different, and half of the fun is in the engineering exercise. We are now starting on a similar set up for my car, with a few differences thrown in, namely, I want a cleaner looking install.
