KR> Turbo to maintain Sealevel intake manifold pressure
I just made a deposit on a new long block 2180 for my KR2. I am in the Seattle area and virtualy surrounded by mountains. I have only 150 hours PIC, but in a pretty wide variety of craft (C-150, Musketeer, C-172, Champ, C-120, C-150 Long range, beech 1900 etc... All of them seem (except the 1900) to run out of "guts" at about 9K feet. I can't remember ever making 10k feet, they all were naturally aspirated. Going over a 4k to 6k mountain range just to leave town leaves me wanting to clear those "Don't land here" speed bumps by oh, say, 5k or 6k ft. Can't get there from "naturally aspirated" here. I am not a speed or performance demon. I fly like I drive: sort of slow and methodical. But I want to clear those rocks (and the bigger ones east of there) by a wider margin. So,, I want a turbo charger. I can find one, but I have not been able to find a controller for the waste gate that will limit the intake manifold pressure to 29.92 inches of mercury. Or I suppose open the waste gate at 3700 rpm. Any ideas? Thanks jg

John: I would say that your proposed use of a turbo charger is its best use but personally have flown C-172s to 13,000 & C-182s to over 15000' for short periods but view 12,500 ft about the limit for sustained operation by a non-smoking pilot or passenger without Oxygen. I believe the craft you site all have service cielings in the 14000 area anyway. Beware of over-boosting as it can be hard on engines and shorten their life. Having been in and out of Prescott AZ several times as well as high density altitude conditions in the Calif. Central Valley and those of the CA deserts I can understand your position very well.

KR> Turbo to maintain Sealevel intake manifold pressure
Hi, I forgot the piper 180 that took 2 hours to climb to 8k feet in the downhill (read downwind) side of a mountain range. I have never gotten anything naturally aspirated to 10k. Perhaps I did not have the time to wait (or the distance).. jg Gotta get high fast..

John: On the down wind side of the mountain you will have very strong headwinds because the air is accelerated to very much higher as it rises(Bernoulli Effect) and then will take a while to slow down as the ground falls away all the while giving you a major down draft to fight as well. When ever I flew from So. CA to IL I would cross the ridge between Las Vegas & Santa Fe NM at either 11,500 ft or 12,500 ft but if I had to stop in either place I would stop after crossing the ridge in my direction of travel because both were tucked in so close to the ridge. Mountain flying techniques are quite strongly stressed when you lear tto fly out west for the very reasons you have mentioned. It is easy to get into situations with small craft that are difficult to get out of.

Interesting, I've had several responses like this one, indicating alot of folks are geting their 10k or 12k ft (even more) with no problem. Here in the Seattle area, the mountains to the east are pretty close. I'd like to have strong climb performance above 6k through to 12k or 14k. No plane I've flown out of Seattle could get to 12k before reaching the mountains which are very close to Seattle. As I recall, I could get to around 6 or 7k by the time I reached the mountains, clearing them by only 3k or so. If I wanted more clearance I'd have to turn South or North and climb (very slowly) from 6 to 9 or so (doubling the time of my trip across the rocks.) If I could get a good (non-diminishing) climb rate I'd be alot happier. I know the prop & wings will loose their grip as the air thins, but if the engine can hold it's revs that should improve things quite a bit. jg thanks for all your responses!

On my stock KR-2 with a 2180 I got about 200-300 FPM climb at 10,000' with just me in it. I am going by my old rusty memory, but that should be pretty close.

I took a 152 sparrowhawk and a Cherokee 160 To 13000 out of Windover Nev. We flew to Jackson Hole and about 5 or 6 other airports at high altitudes ( one was 9350') before we went back to Salt Lake. Lean and fly, People do it all the time. I have flown a KR-2 with a turbo in Dennis Pointers KR before he totaled it and you had to be careful not to over boost. There is nothing wrong with a turbo if you make damn sure you don't ever over boost. It will get you High.

Just did the same testing in my KR2S last week. At 10,000 I was still getting 200-300 fpm with my Revmaster 2100D (no turbo). That is the highest I've taken my plane at this time. I now have 73 hours on her since first flight last Sep.
