I fly a long prop/short prop not turbo charged but then turbo charged and now intercooled 601b. Had the long props for about 15 years and went to Short about year ago as I needed new props and at that time the short props were the most cost effective thing for me to do. I was super concerned about taking a performance hit especially while taking off. Their performance is supposed to be “as good or better” than long props. In my experience, I would say this is true. That said, don’t expect any real acceleration until you hit about 60 knots - that is where they dig in. The long props where able to hook up with the air right away. Under 60, long props win. Over 60, the short props pull harder. Net - I seem to use about the same amount of runway now as I did before. My climb rate seems about the same. Having an unpressurized “louder” cabin, I can tell you that the short props are significantly quieter (maybe 5 to 10 db spl).

So my beast (601P intercoolers and short props) is at the Flight Shop... When I bought it it had a high time engine (1200) and a low Time engine (400) the low time engine had a mechanical failure and was replaced with a Factory Reman. This year its time to do the other side. So it will have two factory reman S1A5. While they have the right engine off I'm having them do the engine driven A/C conversion as well. Tried to order the A/C conversion kit from Aerostar a full month early, alas it seems that the vendor that used to make the A/C hoses for Aerostar has lost the recipe and the plane is now sitting waiting for Aerostar to get its act together. This is unusual for Aerostar I hope its not a sign of company decay. The awesome support from the company is one of the really good things about the Aerostar. So it look s like my 2 to 3 week engine swap and annual will turn into a 6 to 8 week job

Am I reading that right? I am sure you are aware that the supply chain for everything from caskets to cribs has been severely disrupted. No surprise Aerostar would become a victim.

50 hours in the last few months … really hard to beat the old girl … Dodging WX at FL210 is often so much nicer than down low. Now I just need to work on the rigging to get it perfected up high, like today: https://youtu.be/ShjSkTND4YI

Username Protected wrote: That thing hauls ass Bruce. You've got a really quick 601 imho. Seems like it, right? My business partner and I agree it’s the single best flying piston twin in the flight levels we’ve ever seen. Must be the paint job Here’s my dilemma: Because I often fly long legs (900+ nm) and would like to cut out the fuel stops, I’ve got the AUX tank STC in hand and a used tank from John C. It would be ideal but the thing it’s lacking is the power on TO and gross weight that can come with a 700hp plane. In the meantime another 700HP plane has presented itself to me. But I can only keep one. John commented that I might just burn more fuel. I’ve seen the charts, but I’m trying to figure out how much real world range I can really count on in a 700HP plane given the extra burn before I spend 100 AMU’s on a panel update. And does it take 20 min extra to stuff the main tank from the aux?

Bruce, Your 601P with std fuel is going to have about the same range as a 700 with aux fuel. There are good reasons for going to a 700: Speed Single Engine Rate of Climb Higher GW (especially a 700 with the nose gear upgrade) But range isn’t one. If you want more range, put in a set of GAMIs and do the work to get a tight GAMI spread. Also, put in a set of Tempest Fine Wire Plugs. And get comfortable running LOP. If that isn’t enough, find an over-fill cap (warning some over-fill caps require a field approval for use) that will get you 185 gallons. If the hassle of fueling with an over-fill cap is too much, install that aux tank. 210-230 gallons. If you aren’t happy with how your plane handles at max gross weight, put on a pair of the AAC winglets. Forrest

Bruce, I have an overfill setup on my 601P, and I'm happy to show you next time we're in Naples.
It's basically an extra 30 minutes of cruise, but it's surprising how often that is useful.
Apples to apples, the better fuel specifics of the high compression engines in the turbo normalized 601P will always beat the boosted 700s for range. You're basically wasting 1-2 GPH in cruise in return for the amazing ROC and higher gross weight.
Also, I'm told that the 700s are harder to run LOP because the %#$@ run higher, so on a max-range mission the 601 will cream the 700, albeit slower.
