question: what would it take to conver to 172sp
I love the 172r. but I was wondering what is required to convert this great add-on to a 172sp. Is it just some minor tweeks of engine perfomance and a new paint job? Or would it require far more work?

What engine performance tweaks are you speaking of?

I understand that the primary difference between the 172r and the 172sp is that the sp has more engine horse power (mayb a 6 cyl instead of a 4 cyl).
of course interior upgrades.

I think using the other propeller provided gives you similar preformance to the sp(extra 20hp) be it a louder engine noise, thought I am no expert.
Think the C172r 160Hp (C172sp 180Hp oh and leather seats )

Re: question: what would it take to conver to 172sp
The 'R' and the 'S' have the same engine.. (this is covered pretty well in the developmental videos) ..
Most of these light, GA engines are capable of delivering quite a bit more HP than their ratings. If your were to put, say, the engine at hand (IO-360) on a dyno, and test it like an automobile engine, you'd probably find that the HP peaks at over 3000rpm. There are a couple of reasons they aren't set up to run at high RPM..
1)Duty cylce .. they wouldn't last as long
2)Typical GA props (+\- 6 feet) will see their blade-tips reach super-sonic speeds near 3000rpm and become very inefficient (and very loud)
A C177rg gets a 200HP rating out of an IO-360.. mainly due to the constant-speed prop. An old trick (that I'll deny), was for a pilot to get his high-performance endorsement (greater than 200HP) in a C177rg, by having the prop governor set up for a slightly higher RPM..
ANYway.. the 180HP comes from a prop that allows the engine to operate at the higher, 2700RPM

thanks for the feedback. Maybe one day a nice leather interior will show up. Until then, I will enthusiatically operating my 172R.
When you change the prop do the rpm range markings change
