My turbo-delsol- aero mods

I decided to start another thread to show just aero mods I'm doing as of right now.







I have all the templates made now and the top piece finished.

I'm using clear .060 acrylic sheeting. It has a aluminum frame for attachment.

Next on my list is to cut the side pieces and the bottom.

Future mods will include

full belly pan
outside mirror delete install video cam
front bumper cover mods
rear acrylic sheeting wheel well covers
wiper cover
pizza pan fron hub caps

Looks great! What are those side templates made of? Are you using the acrylic throughout?

Thanks!!!

I'm still going to make some minor changes. The side panels will be clear acrylic sheeting also.

Yep, with a personal best of 74 mpg.

I'm hoping to squeeze another 20 mpg out of here with the new aero mods.

awesome save gas for more mods! I think you're my new hero

aero mods look good... listen to Christ I feel like he knows his stuff. (he'd better with a name like that huh?)

so I guess I am going to read through your posts to find out how much HP you have and learn about how you do this cause I too want a car the saves gas when I want and can hang at a hill climb too.

Thanks Man!!!

I'm thinking about shorting the boat tail by about two feet. The Del Sol design is kicking my arse as far as the way the Qt panels meet the roof. I'm trying to keep the transition smooth from the top of the Qt back. It makes a major bend behind the rear wheel well about 20 degrees and I don't know what to do with it?

The car now make 450whp. It can go from 74mpg to 5mpg by simply pressing the go fast pedal all the way down.LOL

Awesome! In for results, my ghetto kammback fab turned out to be a dud. Back to the drawing board.

450 WHP from the 1.6L ? B16 ? Dyno proven?

Need to see pics / videos asap! Any links to share? Once fully aero-modded you are going to have a real highway monster.

That kam-back is looking good! Any pics of the bare frame? I see your challenge on the side angles. I think a lot of your problems might be aided by just shortening the overall kamm length. That's quite a commitment as you have it now. I think you'd get a large % of the potential gains even if it were 1-2 ft shorter.... no?

Also kind of looks like you need another hard break on the sides. If you keep the angle between panels low enough, separation on the rear piece shouldn't be tooo bad.

I decided to sketch it:

testing

If it's at all possible,I would encourage you to tuft-test the tail before you commit to the design.
Anything above 20-mph ( on a dead calm day ) will tell you what you need.
It's hard to tell from your photos,but it looks like there is a sudden,angular transition at the roof,and reflex at the sides especially below the beltline.
If so,you'll have immediate separated flow ( exactly what you're not looking for ).The flow will reattach on top with some efficiency loss.I'd be suspect to the sides,as there is not as much energy available to sustain flow.
What you've mocked-up holds much promise,and a quick test would soon tell you whether or not to cement your design.
