What is the max towing weight (max weight of the glider) for the PA-18 150 hp and 180hp?

Where can I find information on this (on the net).

Thanks!

As long as a Tost hook is installed, there are practically no limits.
There are two 180 HP PA-18's operating out of Boulder, CO where
density altitudes can reach 9,000'. They routinely tow fully loaded 2-
seaters. The PA-18-150 has significantly less performance which is
why none are used in Colorado. While information on hooks is
available on-line, towing performance probably isn't.

I recall the late Dave Johnson, who developed the STC for the 180HP
Cub, saying a 180 HP Lyc. O-360 is only a few pounds heavier than the
original O-320. He went on to say it seems like the extra 30HP
provides a lot more performance than one would expect.

The Schweizer tow plane hook has a limit of 1200 pounds which is
inadequate for heavier gliders but the Tost hook limit is 2570 Lb
which easily handles any glider. For that and a lot of other reasons,
the Schweizer hook should be retired.
