    After a 2 1/2 year build and several shake down runs on slower streets I'm ready to hit the interstate and have a few questions.
    The windshield has to be fully closed correct?
    I've been up to about 55 mph and I here a lot of wind noise around the front windshield. It almost scary. Has anyone ever had the vinyl roof get damaged by the wind?

    Nope. Drive my sedan at highway speeds with windshield open and windows up or down. No problems. The top material is old too, probably 50s or 60s.

    There is noise but if you adjust the angle a bit you can change the frequency of the wind noise n
  6. If my rpu can click along at 60- 70 you can criuse the same. Had to reinforce the center top bow thou . It collapsed first time out. Ya you'll get wind noise.

    The faster you go, the less scared you become. Find the "edge".

  8. Seriously,a Model A has the aerodynamics of a barn so there is always going to be wind noise and yes you can drive with the windshield pushed out.

    As you drive the car you will get use to the noise and the fear will subside.

    As for the top,yeah I had a friend that lost one but the top on my deuce is still intact and it's never been replaced..I've drive the sedan at 85+ and the top insert is still on the car. HRP

  11. Before I put AC in my '28 Tudor, I drove all the time with the windshield cracked open about 2". I read that Model A's were designed to take advantage of the laminar air flow next to the body. Laminar air is cooler than normal air temp. The bottom of the windshield frame has about a 2" lip. The cowl is designed so when this lip is not past the outer edge of the body, the air is directed down towards the floor. . Try it. You'll see the air is cooler. It works with the windows open, or closed. Before the AC, I drove my sedan to Vegas twice in September, and it was not uncomfortable in the car with the windshield cracked open.

    No damage.. been up to 75 mph, but I always have the side windows open when the windshiled is kicked out. Henry's ventilator is quite awesome, pushes the air down to your feet too.

    My Model A coupe has over 80k on it, much of it in excess of 70mph with the windshield cranked open. The top balloons a little at hwy speeds but it has never ripped.
    I had it up to 105mph on the Fontana Speedway and the air under the front fenders was the biggest issue. The front end gets really light at those speeds. At highway speeds, no problems.

    What Model A's I've had a ride in on the highway have all had a bunch of wind noise and a lot of other noises. I don't expect my Model A Vic to be quiet on the road either. Not as bad as the 48 with no windows in the doors what so ever I hope though.
  16. I always run with the windshield propped open. The wind noise doesn't bother me because the exhaust is louder!
  17. Wind noise was not a problem in my '28. The Champ QC cancelled it out very effectively.

    When my A had turbo mufflers, the wind noise was really annoying.
    Now I have straight pipes. Presto, no more wind noise! LOL
  19. Loud pipes diminish wind noise! I got both.
  20. If you're looking for a cool, quiet, comfortable ride, check with that Cadillac dealer down on the corner. Hot rods are supposed to be a little "edgy". Get in that Model A, push out the windshield and drive it like you stole it.:D

    As said before, crack open the windshield a couple of inches and you get air down on the floor.

    Watch out for the bees that come in though the opening. They will land on your crotch and be rather mad.

    The whole idea behind a crank out windshield is for ventilation, it's like 2x55 AC except it makes it 3x55 AC, Crank it open and let fly.

    Make sure the knobs are good & tight, and your passenger doesn't have their a grip on the dash rail

    maybe it's because of spending so much of my life on motorcycles... but never thought the wind noise was much to speak of in an A.

    also, what's that ringing? can you hear it? is that the phone? (OK, do maybe I'm a little deaf :) )

    when I ride mine down the interstate I run 80-85 windshield wide open I never shut it.....It makes it a real nice ride.
  28. I don't have a Model A anymore but my Deuce sedan has plenty of wind noise,but opening the cowl vent will cut down on the noise. HRP

    If you are concerned about wind noise in a Model A, this may not be the hobby for you.

    Mine has been 128 through the traps and 100K plus miles on the street with the front windshield cranked out all the way. You should be fine.

    I did have a bird fly in the windshield and hit me in the snack once, but I'm sure that kind of shit only happens to me.....

    Good luck, -Abone.
