Great update Jess
I enjoy the thread as well.

After 12 hours, an approach, blowing ice off the boots twice, and some cross countries it was time to check our work.

Today we cut the filter and found zero metal. Unusual but great for a new motor.

We turned down RPM, cranked up MP, lowered oil P, swapped #3 and # 4 injectors, among several other tweaks. I decided to take her up higher to see how she’d do in a sustained climb. 1,000fpm through 15,500 and the hottest cht was 383.

LOP she made 183ktas at 15,500, but still needs tuning. Very smooth and stable performance. The new motor runs like a top.

That right there is damn impressive Jesse! Sounds like the new motor is ready to go the distance.

Awesome! What was the gph? Also, from the video, wasn't the hottest CHT #6 at 393 deg? Thanks so much for the postings....very educational and entertaining to watch.

The 383 was in climb. Without the gamis dialed, the #6 rose to 393 in cruise at 17.2gph based on the video. I still need to tune KFactor and swap some gamis etc. so hard numbers will take awhile.

With the new engine install, the plane runs better LOP up high. I'm starting to give up on 190ktas and may have to settle for 185. Baron speed ain't bad considering my 58 with 520s ran out of climb at 13,500 and this was still making nearly 1,000fpm through 15,500'.

I enjoy it so much, I would love to help other guys maximize their planes.

I REALLY like factory turbos since they are much maligned but have the potential to be real animals when dialed in. You'd be amazed at the tiny issues/adjustments that can add up to big gains.

Yes - the airframe has several mods including the turbo-plus cooler and cowl.

Jesse, this blemish on your otherwise perfect airplane is giving me Forest Whitaker eye.

John, couldn't help but notice you said "blemish" singular.
Which one did you mean, the red or the blue ?

Good eye!

That's actually a loaner unit since my BK did me a favor and died.

I suppose you stole my thunder but I am "on the schedule" :).

Long flight today

I flew 5:32 and landed with 16.2 remaining which is about 1:06 reserve. I powered back to long range 27/2300 @ 14.7gph to save a fuel stop. I had headwinds the entire flight, TAS was between 170 and 160 as I descended to 8,500'. I think if I really pulled it back it would stay airborne for 7 hours. If I weren't fighting headwinds, this setting should give about 175ktas for 5.5 hours with a 1 hours reserve @ 15,500'.

The left tank took 54.4 which is 3 gallons more (in each wing) than "usable" total of 103.

When I ran it dry, I tried to simply switch tanks with the boost pump on, but I eventually needed to enrichen the mixture to settle down the flow. The engine ran for 16 minutes while both the wing gauge and the panel gauge indicated "0". Thats 40 NM of fuel. The gauges are quite accurate compared to the posted usable fuel...but now we know there is another 1/4 hour in there.

Can't wait to see it. Carry on.

Very cool!
I have a Turbo Lance; not getting anywhere near your numbers. Probably mostly because of the stock cowling. It’s still an amazing family hauling machine.

Another vid. 188 ish ktas at 17,500’. Tomorrow I’ll bump up MP, retard timing 1/2 degree, swap 1&4 injectors for richer, 5 for leaner, and drop oil P a bit. That will get CHTs back where I like them in cruise while adding power to two jugs.

This bird will do 190. It was really happy today at 17.5. I didn’t even need the boost pump. I also pulled it back and it will do 180ktas on 15gph up high. Total range is 1,150 pulled back.

She’s coming along.
