full skirts verses partial skirts
I admittedly expressed a point of view regarding partial skirts to the effect that partial skirts would only serve to trap turbulence thus eliminating any mpg gain.
Let me try and explain the idea of the full skirt as applied to my crx. The skirt is a full skirt made from3/16 abs backed with coroplast and affixed to the wheel housing with six nylon license plate screws imbedded into the back as to add to the cosmetic appearance.
I used a seal consisting of breath able 1/4 inch hose which i beleive is called soaker hose and the reason bieng was to allow the skirts to exhast excessive turbulence via the soaker hose. In addition the wheel housing underneath the vehicle comes to a abrupt curve which in effect served to trap the turbulence further. To resolve the problem i driled eight one inch holes into the lower wheel housing at the abrupt ending of the curve, this i did to both sides of the vehicle.
After having drilled the holes i bent the base of the abrupt ending of the wheel housing into a gradual curve to allow any further turbulence to escape.
A quick test drive proved out my theory that the full skirts were indeed effective.
The full skirts sit flush against the center pin for the racing disks and during the test run which was for a period of three months the skirts did not deviate from the position they were placed.
Were the full skirts ineffective the skirts would have flared away from the pin holding the racing disks.
There is a lot more to placing full skirts on a vehicle without thinking of the consequences of ones actions.
The air traveled over the skirts as i had expected and the work done underneath the wheel housings was well thought out.
let me say that i have worked on rear skirts for over two years verses a scan gauge test with out the work that i have done.
The full skirts in my opinion do work and it will take more that a tufft test, scan gauge test to debunk the effectiveness of rear fender skirts.
Had all of the work i had done been applied to the vehicle i am certain that your results would have been quite different.
I have sold my crx and with a little imaginatin i was turning 64.5 mpg consistantly............
I am now in the process of modifying a honda del sol...........
It is not my intent to make anyone believers of the full skirt or anything else, all i have done is share my work with others on ecomodders........whatever one decides to do will not be based on my experiences but based on the results pro's and con's that you have determined
The next set of skirts will be simplicity at it's best, all of the tufft testing and scan gauge readings will still indicate that rear skirts are ineffective contrary to a 4-5 mpg gain, don't ask me to prove it as results will differ, body work is my line of work and i do know what i am doing, 15 years perviously in the trade.............can you say the same? and a sculptor which means i know what lines it takes to effect smooth aerodynamic lines
As said before expressing an opinion as i beleive nothing is written in stone
