You'll be quite happy with the 9.12 knot increase from no wheel pants, and a
6.95 increase over the old style Piper wheel pants.

Well, from their own desciption, it looks like the difference between
'78 style Piper pants (what he would get with item #2449226814) and
the Speed Pants is only 3mph ?

My understanding re most of the speed enhancing is that they say "UP TO" bla
bla increase. That is, they guarantee no more but you can get less!

In flying without the nose pant on my 79 Archer, I can see no difference in
speed, climb or handling.
