Tomahawk 125 hp STC performance?

Well, there is this kit to boost your Tomahawk to 125 hp. However, so
far I could not find statements on speed gain and fuel burn.

So my questions are
o How fast do you go with it?
o How much fuel do you burn?

Thanks

A 12hp gain over the factory engine would not do much for cruise speed
(5kt?) or change fuel burn noticeably. The climb rate might be a bit
better though

Oops. That's a whopping *13* HP gain over the stock PA38-112.

Weak math skills. My bad.

You can soup up a VW, it's still a VW.

One of the best things about the Tramahawk is that you can sit aloft
for hours on end on next to no gas. The 125hp engine must suck more
gas.

That is still around a 10% improvement in HP, so it should be noticeable,
most likely in climb and in fuel burn.

I thought the best thing about that airplane was its sturdy landing
gear. I can personally attest to its strength after several carrier
landings when I was training for my PPL.

Nowadays, the 125hp Conti-powered Katana is just the thing to buzz
around in and not burn much gas - at 130kts to boot

I owned a Tomahawk for several years. Realistically, it was a 100-105 knot
aircraft - the book said 108, but that was for a factory new airplane.

Anyway, I just ran the numbers and you should expect to burn 7 gph at 75%,
and you'll see maybe 4 additional knots of airspeed. The biggest improvement
will be in climb performance. At sea level, you should see an additional 250

I rattled my own teeth, and my instructor's, a few times; before the
extended float float from a couple of faster than normal approaches gave me
enough time to observe and learn. After that it was easy to be fairly
smooth--even though the undercarriage is a bit stiffer than on a Cessna 152.

OTOH, you definitely *can* break it. The FBO I rented from had two
Tomahawks--until some fool stalled one much too high. (Truth be told, I
never found out whether he simply slammed it down on the mains or let the
nose drop as well--it happened at a remote field and IIRC there was
additional damage from the recovery and transport.)

I am looking forward to trying the Katana, as well as the Sport Cruiser.

That confirms what I have long suspected: I could only justify it to
operate from a higher altitude airport--which is just not in the cards.
