Cirrus continues to be bullish on turbocharging and has announced a new model, the SR22T. Cirrus rolled out the new airplane at the Cirrus Owners and Pilots Association Migration in Dayton, Ohio. The model is a follow-on to the SR22TN, which has a turbonormalized version of the IO-550-N installed in the normally aspirated SR22. The SR22T has a ground-boosted TSIO-550-K with 315 HP, five more than the TN model. The SR22T's TSIO-550 has low compression pistons - 7.5 to 1 - so Cirrus sees this as a path to the use of lower octane fuels. (At least lower than 100 octane.)
