Well, All I have done for the last two days is cruise around at 35mph on the back roads between my place and the job. 70-75* today and its actually a bit warm in the car. Windshield makes the motor build temp in a hurry. fans kick on and it drops right back down. If I click the fan override switch on then it is way more comfortable in the car but the engine running temp drops to like 170 and that's too low. More testing required

[bikesndbugs]

run only one fan? for mid level airflow that would take some wiring just a thought. or make a scoop on the roof that puts some air down towards the radiator

[Leatherneck]

170, yeah that is bath water temp around here.

For some reason I am having a heck of a problem posting here... again. Two long posts and nothing!

The problem of the wind wrapping around the windshield is an old problem. Going back at least to the '20s if not sooner. There are "wind wings" (https://www.bing.com/images/search?q=mo ... ORM=IQFRBA) that attach to the windshield posts who's job is to keep a lot of the wind from wrapping around and giving the people in the front seat a wash of wind and grit in the face. They redirect the wind's curl around farther back in he car (the wind is deflected by the wall pushing it away and then rushes back to fill the vacuum. That is why the windshield get dirty both on the outside and inside. I removed the windshield on my buggy for two reasons:

1) the dirty windshield problem. Riding on the sand in Oregon the salt air would dirty up both the inside and outside each trip out. Before each trip I had to do some cleaning to be able to see where I was going.

2) if you have a windshield on the Oregon dunes the law says you have to have operating windshield wipers. Less wiring to do.

Whale tails and other directors just move the vacuum fill farther back (windshields interrupt the wind so they do that too. In the old days on square backed station wagons you put a deflector on the back the idea being that you direct the wind down which kept the winds curling from dirtying up the rear window so fast.

Sporty car people usually keep the door windows up for the same reason. If you watch them, with the windows down, their hair is usually blowing forward towards the windshield.

On pickup trucks. If you hall dirt or sawdust after unloading (not sweeping out the bed) and drive a bit the back part of the bed is usually clean. The same thing. If you have a bed cover you can watch the wind on the cover. The front of it stays flat but the back part dances around.

Sorry about being so long and so basic but just-in-case there are people who didn't know this.

I mean its not all bad...its down to 58* now I just came back from a 75 mile trip still just in a T-shirt and shorts. I did turn the seat heaters on.

[Leatherneck]

Seat heaters lol ahhh you suck. Come on down here Daron, put the builders here out of business and during the summer you can hear the fat frying right off of you.

Ask Matt Dormack how well a plastic windshield works in dusty conditions. The plastic gets a buildup of static from the air flow, then dust sticks to it. then wiping off the dust scratches the plastic.

Glass is good, acrylic or lexan no so good. NASCAR and road racers get away with it only because they don't drive in dust.

[Piledriver]

Static dissipative lexan then.
(It is a thing)

So what you are saying is I should have just gone to a piece of glass vs experimenting with a $50 piece of lexan to see if the car would even cool itself with a windshield installed? Honesty I may end up with glass. But for offroad use, then I need to worry about rocks breaking it. I know that the Lexan will not pass for "Street Legal" but I can have this Lexan out in 5 minutes and my helmet on in another 5 for offroad use in the dust. I may stay with the lexan and then have some NASCAR style tear-offs made for the inside and out.(They will be much less prone to scratching) and even though HotVW's magazine had no interest in my car, there are others in this industry that are more then willing to help me, help them, promote their products. Yes I have already been in contact with one of the major producers/suppliers of NASCAR style tear-off and they are ready to work with me as soon as I decide if that's the route I want to go.

Also, I was in no way surprised with the results of this testing from the static cling of the dust so far, or the warm air rush from the engine coming in on the back of my neck, I was simply reporting back and opening up the discussion which I do appreciate the responses. What I was surprised with was the noise and vibrations and everything that goes with being able to hear more then just wind in my face 5 miles in the car on the pavement leaves no doubt that you are indeed driving a race car on the streets 35mph in 4th gear cruising at 2000 RPM is kinda nice.... 70mph on the interstate at 4250RPM is obnoxious. And yes I did take it on the interstate the other night

I do not really even notice the RPS in the dirt at 70 but that is also with my helmet on and I am paying way more attention to aiming the car at that point too.

More testing is required

More testing is always required. I like wearing the headphones so I can't hear as much of the car noises, drives me crazy. What was that, did I hit something, something break, ahhh what's that new sound? You'll get the windshield figured out. More testing

I'm laughing at myself (and you guys) as I read your posts. When I sorted out my tub buggy and triangulated everything, I was astounded by how much extra noise there was inside it. Needed ear plugs to drive it with the roof on. Swore I'd never have such a noisy car again... until I put the trans strap and the kafer bars on my current street car. Yes, I'm an idiot. I guess there's always dynamat.

Kind of like walking down an alley between close in buildings on each side or walking down a sewer tube isn't it. Tubes are closed so noise is not dissapated easily like normally would happen. Kind of like a drum w/o the air hole in the side. .

Ever tap a roll bar or the tubes of a rail w/a wrench?

70mph at 4250?! You didn't build this as a high speed cruiser for sure. That gearing is taller than my 3 rib.

Even in our trail rides we are hitting 65-75 on the dirt transitions for hours.

[bikesndbugs]

70 for me is like 3k i dont even have the power to get it to 4250 unless im going downhill
