I bet some really smart person on this board could come up with a portable wind tunnel built inside an old semi trailer with big glass panels on the sides so it could be brought out to Bonneville and he could make a fortune off of us racers!!!

T-2011 here;  we built a wind tunnel in 2009; it's test section is 12" square and 24" long - overall length is ~ 9 feet; using a home basement fan we draw about 35mph and can test 1:10 scale models of the kind we do (not long streamliners).  PACCAR does not have a windtunnel at their Mt. Vernon Technical Center.

We took advantage of the 20-25mph (no racing) cross wind on Thursday at WOS to plain point our car into the wind and look at aero with a little American flag and lots of tuffs attached to our car.  We took lots of video and it was very educational and revealing of how the air was flowing around our car.

You know Sparky, sometimes the photobucket pictures disappear or do funny things. If you post them just like you posted the picture of the fan, clicking on that picture results in a nice sized picture that remains with the posting so we can refer back to it in the future.

Just sayin'! :wink: :wink: :wink:

dont waste your time with that fan and motor unless your doing scale stuff... we fired up the tunnel last week and again all day today... it has 2 429 fords with 5' carbon fiber blades with both motors running she pulls 50mph, just right for full size motorcycles...

Kent,  Thanks---I got a private email that basacially said the same thing---can move no more wind that a scale model---because of presure waves  :cheers:  :cheers:

Kent,
What are the dimensions of your tunnel? Do you do full scale motorcycles in it? Moving floor? How about a picture.

Rex, did you notice the silence from 1212 about tunnel specs?

There is one amazingly simple but informational tunnel in So Cal that works really good re: vizualization. But the owner realizes it way too puny for his near 300 mph speed range.

But you will see changes garnered from his tunnel next year!

Waiting to see if they show up on his time slip!

Sparky, I'm sorry I didn't get to meet you in August when you came over to visit the 608, I was busy on the other side of the car and wanted to finish whatever I was doing. But,

Dontcha think that sending a volume of air over a section of the car that you are concerned with will help with visualizing  the area? Tuffting or even sticking your hand in the air would help. I think us garage rats
could do without the fancy load cells and computor results. Or you could tether the car with a fish scale and read the results :wink:

Tuffting I have done to several suprises,  one of the most informing(but costly) things that happened was forgetting to turn on a pump and spewing water all over the inside of the old RATICAL. The water that got out from under the skin joint laps  left some very intresing "TRACKS"

1212 - does that mean I can't take you to the SCTA banquet?

Seriously, I thought the dual 429 engine deal was a giant leg pull.

I pictured the tunnel structure a half block long!

But, WHILE you were racing - and I was repairing a crashed Fuel Altered, incidentally, I was trollin' the internet for more KNOWLEDGE!

As my old Spanish teacher used to say "Saber es Poder"

(One of yor employees can tranlate, I'm sure).

Talked to a guy once who retired from Lockheed Martin or McDonald Douglas or one of those guys...

He told me a story of a wind tunnel they built in house to test small components with out having to tie up their full sized wind tunnel.  They called it "the toy".

He said it would have been perfect to test motorcycles in.

The fan was powered by a 426 hemi!!!

It takes a lot of horse power to move air.

The full scale wind tunnel at the old LTV plant in Dallas had 33,000 hp! They had to let the power company know when they were going to run as it dipped the line voltage so badly on start up.
