Streamliner Design

[WOODY@DDLLC]

The last 2% of any project consumes just as much revenues & resources as the first 98%! 
In this venue you will become expert at modifying the modified, modifications!

I blame you guys for my troubles. Too many great designs and approaches         

WELP.......atleast I have a better chance of not killing myself I guess.

That may depend on your wife accepting your new mistress competing for your time!!

Now I see why lakesters are so popular. What a pain in the ask trying to tuck tires into a space that pretty much doesnt exist. Is steering really necessary?

Like brakes, only for getting on and off the trailer.......

[Stainless1]

But that's half the fun of streamliners... hiding the tires from the air....
Yep... even lakesters shouldn't be able to make tight turns... a 1/4 mile u-turn is as much steering as you need.  You learn to master the 20 point turn in tight spaces.

I decided no steering or brakes at all. Dont really need it. Instead, Ill have two oars/rutters that dig into the salt to steer. John @ Shroud must be busy because Im still waiting on the quote for the boat anchor launcher.

[Stainless1]

Launcher?? Are you using a round tube with a spring pilot or a rectangular with a pneumatic ram pilot?  We have pneumatic rams available if you or anyone else needs one... new, just pay shipping and give Slim $10... I can get the length if anyone is interested... thinking 10 inch stroke w spring retract.

I thought this was funny and many can relate.

The helmet finally showed up. I guessed the basic helmet size right, but the side air inlet through me a curve ball. Ill also need add height to the chassis, if I dont want to strain my neck forward.
Its a step forward.

Looks like your mainly asking for aerodynamic help, but don't forget weight balance.
Your drawing looks rear heavy if the motor is in the back
We ran 50/50 front/rear
I definitely would not go past 60% on the rear

Back to aero ...The nose on our car had 0% lift at 380 mph. Roughly copied off Micky Thompson's 2nd car. The problem with sharp corners on the body is your not always going straight into the wind. The air need to also flow with a cross wind

Helmets keep getting bigger all the time. Safer, I'm sure, but a PITA when it comes to fitting in a roll cage.

Yes sir, its 3/4" taller from the centerline of my eye sight compared to my old helmet.

Hoffman, the basic lay out has changed a lot since my original post. I posted a few concepts within the thread. Moved everything forward. Challenger 2 was also my inspiration. As time goes by, the influences from everyone makes me question it all. My original thought was to not create even the slightest amount of high pressure in front of the car but rather have it aft of the leading edge. Now Im starting to realize that slight high pressure is actually better for the aero overall. The air will be disturbed no matter what shape we use, so the quicker its disturbed, the sooner it can recover.

Beautiful hot rod you got there.
