Title: Sonerai Cowl Rework and Turbo Installation
Experimenter: Jeff Lange
Date: May-Oct 2013
Author: Elliot Seguin
Description: In the never ending quest for more speed, long time cross country racer Jeff Lange decided to redo the front of his cowling and install a turbo charger. This required composite fab, exhaust fab, and significant systems work. The result is the first turbo charged Sonerai. The airplane has not yet flown with the turbo, but has almost two hours of running on the ground. This testing has revealed almost a thousand rpm static improvement. Covered on his blog (link).
Argument: This mod requires significant multi-disciplinary work over many months, resulting in a first for the Sonerai type (turbo charging).
