Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.

VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Back in the day I had a 46 ford that had a booster vacuum pump. However I don't remember much about it, but it worked well. I'm guessing it was an aftermarket accessory.

Ford offered an optional mechanical fuel pump that incorporated a vacuum pump to provide a stronger vacuum source for the wipers. This fuel pump mounted in the same location on the Flathead V-8's as the standard fuel pump. It was optional equipment on 1951 to 1953 Ford V-8's. Dennis Carpenter offers one as part number 1BA-9350-N and refers to it as a Double Action Fuel Pump.

First, determine if it is lack of vacuum that is causing your problem. Connect a vacuum gauge to the windshield wiper port on the intake manifold. If you have a stock cam, the reading should be around 20 inches at idle. Here is a link on how to read and interpret a vacuum gauge.

If you get normal vacuum readings, remove the wiper blades and drive around with the wiper motor running. This will help the lubricant with in the motor. Lubricate all pivot points on the wiper drive arms and the shaft that comes through the body to drive the wipers.

Your wipers should operate fine at a steady speed and slow down when you accelerate. If they do not do that, check for worn parts in the linkage. Worn and sloppy pivots can cause binds in the operation.

Additional info here:

Many other discussions if you search. Your wipers, if operating properly, should operate more than adequately and far more quickly than you think - all without a bandaid/'upgrade' vac boosting system.
