I think it's Joe Bruer who has/had a turbo Tiger. Correct me Cliff.

What was it's cruise altitude and what did it true out at?

Gary,

It is Brad Brotherton that has the Turbo. Joe Bruer had an IO360 with a
constant speed prop that he sold a couple years ago. THat plane is in
Northern, CA now Miwuk Village owned by theHawk's

Brad's Turbo Tiger was a one time STC gained around '85 or '86 by Seaplanes
something company near Seattle and when tey ent bankrupt the plane and or
STC was auctioned off. This a little sketchy but that's the gist of it.

It has NOT flow for many years and is in a very poor state of repair having
sat outsidde a number of yeara with a broken nose strut torque tube and a
run out engine and etc...

Brad told me he usually cruised at 175 mph. It had a fixed pitch prop which
severly limited t but it was certified for 25,000'. My notes get a little
sketchy here again but he mentioned he flew it once 215mph TAS at 18000' and
calculated that at 25,000 it would do 230mph TAS

BTW, He won't sell it:(

Best Regards,
Ned

<2 cents>
But he'll let it sit and deteriorate? That's lame and seemingly idiotic.

No, it's Brad Brotherton.

Altitude is anything you want, but it can only really take advantage of the
turbo during climb because of the fixed pitch prop, a Sensenich pitched to
66" as I recall. About 3" MP over atmospheric will overspeed the engine
even with that pitch. I had heard that at $25,000 ft. it was still climbing
at 400 fpm. It is faster than other Tigers down low due to the 66" pitch,
probably pretty close to your plane, Gary. The MT prop would be a very nice
prop to try and should improve the cruise significantly at altitude.

From what Brad told me I don't think it went anywhere near that fast at
altitude. It is very unrealistic to think that a turbocharged model of any

plane will increase cruise speed by 55 mph from a normally aspirated optimum
cruise altitude of 8000 ft. to 25,000 ft. About 25 mph would be the most
you would expect. And that would be in line with what Brad told me that he
expected 200 mph at high altitude.
