Rear Engine Modified Roadster Build

[Captthundarr]

Tony, would that be high pressure or velocity under the section in front of the cockpit. I have a '27 roadster hot rod project that never got past the roller stage and I have been contemplating a RMR build for the OHIO Mile, After I get the wife LSR Camaro done of course. So I follow folks build closely.

The plots are relative pressure on the flow trajectories.
Red is above atmospheric and blue is below.
Try that with your wind tunnel smoke!

Don't remember the '27s looking so v-shaped from the front?

[4-barrel Mike]

That's a '27??

Tony, Those are not the same pictures you sent to me! WTH?

That computer modeling is cool. Wish I knew enough to do it for our lakester AND know what the heck I am looking at!

[Stan Back]

Maybe it's a Pierce-Arrow with both the pierce and the aero.

Copy that Tman. I recently scored a copy of solidworks, and man, just getting through the tutorials has me scratching my head!

Looks sweet Tony!

Tony,   On your pictures in front of the nose is shows an increase in pressure then reduces as it moves further away from the car, I guess that is because of the pressure build up off the nose?

At speed the air makes it look like a '27.  Tony

Guys, I cant take credit for this.  All of it is Woody's hard work, and without him none of this would be possible.  Tony

Tony or Woody:

Would there be an advantage to widening the front axle so that the front and rear wheels were lined up? I realize that it would present more frontal area or at least different frontal area from the wider front end components but would aligning the tires with the backs directly behind the fronts be an advantage?

Tony, you need to use a different avatar for the posts where we're supposed to concentrate on the subject contained in the post.

Pete, we did an ANOVA study on the wheel tracks narrow and/or wide. ANOVA is short for Analysis of Variation.

Turns out they are pretty happy where they're at! But this will always be case-specific based on the neighboring geometry!

F1 & Indy car body shapes are roughly based on the flow around the 4 open wheels or in their case "spinning round bricks"!

Tony, I think these guys are starting to get wise to us!

     Tony - wow! Make sure I know when you take that thing thru tech so I can listen to the whining and watch the headscratching. Sorry I missed you @ Speedweek.

     @Tman - "AND know what the heck I am looking at!"  You and me both! It also applies to data acquisition analysis.
