RE: Is this too tight of an engine install ?
Thats allot of power for that bird...
They fly exelent on a 160. You might see some heat problems and i dont think the standard 160 pipe will hold up to a 200.
Also at full power it may move in the mount.
Also make sure the gap from the cone to the bellmouth is 3/4 to 1" or it will run hot.
If you want to run the 200 i would contact Tam and have a shorter pipe made to support the engine and push the engine back.
Take care Wojtek
