I flew a skydive C182 with the Texas conversion. Awesome for climbing fast. 2 tandems to FL140 faster than any other C182, over 1000fpm thru to about 8000'
BUT the extra HP does nothing for it's long range cruise, high fuel flows for not much faster. IMHO.
Could get the VSI off the gauge climbing at 80kts with only or 2 POB
