I prefer to call them "Whale Pants".. :)

In defence of the the clown feet, the early Velocity sales literature said something like, "Everything generates lift: the wings, the fuselage, even the wheel pants!" I think whoever designed the wheel pants tried to put a little airfoil around the wheels. And maybe it works. If they do generate a little lift they will be draggier than a more streamlined wheel pant, but theoretically the airplane would be able to drop its nose an imperceptable bit and reduce drag. That would explain why the more streamlined wheel pants don't seem to add any more speed.

For what it's worth, I've got a brand new   unfinished pair of original "clown feet" wheel pants that I'll give free to a   good home (you pay shipping).  First email to me wins...

Nice looking pants.   Wish mine came out that nice looking.
Something you might consider is to add vents to the top of the pants to   let the 
heat out. I do not know first hand   but was told by a couple of long easy guys it helps a lot in keeping the   wheels cool.

Andy,      

I asked someone at the factory     that very question. I have the Old style ones and thought it was worth     asking. I was told that they are all about the same as far as speed goes. I     think the newer ones may be a little more user friendly to remove/re     install. 

Since there was really no     advantage to buying new ones, I just redesigned my old style     ones.

Here are some pics of what I     did:

Does anyone know if there are     improved wheel pants (more aerodynamic) for the 
standards out there?     I've seen the XL ones.

If so, how many knots did you     gain?

Hi   Renee,
That is very interesting. If you have   any links on what you saw would you mind forwarding them? 
Thanks

Over old ones. Lots of Vans RV experimenters out there with similar     speeds almost.

Kurt,
Those look fantastic. How       big a project was this? Seems as if this was fairly extensive on       glasswork.
I'm as we'll looking for a       better look. My research on speed same as yours: all shapes about the same       in drag reduction/speed gains.

Re: REFLECTOR: Engine         air intake

I've noticed my MAP is   1-2" higher during climb out compared to after I level off.  My inlet air   scoop is under the belly.  I figure at high AOA there is more pressure   underneath.  And perhaps the scoop is a bit in the boundary layer during   cruise.  I'm curious about your findings.

Kerry, I ran across your email         and here's my 2 cents worth:  I have a standard SE IO360 and after         some experimentation, have settled on a air intake system that gives me         about 1/2" of positive pressure at 140 knots and at 185 knots TAS 3/4"         of boost.  This pressure is measured down stream of the air filter         (KandN) just prior to the air entering the fuel servo.  If you are         interested in some of my findings, feel free to call or email me.          Lynn Cook 530-878-2002

There has not been any           mention of what works best for intake air. If someone has found a good           way to pressurize the intake would they share what they have           done.
Thank You

Re: REFLECTOR:         vernatherm

The old   oil cooler is a Niagra 2006H and measures approximately 6x8x3”. The new cooler   will be a Positech P2008C which measures 8x8.63x3.62”. 
Thanks for the response.

I     would appreciate comments from those who have done this. Is there a     modification necessary for the factory oil bypass valve?
