Project: Del Sol Kammback Trial Mockup

[jedi_sol]

So I got the idea of putting a kammback on the back of my Del Sol thanks to some senior members of this forum. Here's what I was able to do with a couple hours of time and cardboard.

Do you guys think its worth continuing (perfecting?)

What's the angle on it? It would be worth fiberglassing with a lexan window for sure if the airflow is attached. Nice work!

PS: I think the angle might be a little too steep. Run some tuft testing trials and see.

Angle from roof to trunk is approx 14*.

My first concept image has an angle of 11*.

PS: I haven't done anything scientific about this project, I was just testing a mockup to see if it's worth continuing.

Thanks for all of your input.

great

do you feel a difference in your car behavior ?

With my rear wheel skirts, the car coasts longer and I feel the car more nervous.

PS I note the idea of using double side tape to second the single side tape to attach the coroplast more securely when I'll try a coroplast kammback.

Hi,

It might help to try and curve the initial transition off the back of the roof?

Clear engine lid cover/fastback style for the MR2? - NASIOC

The rear window area of a Del Sol is similar to an SW20 MR2. Check out what the MR2 guys in Japan have done. You won't need slots because you don't have a hot engine back there.

Hm... amazing how the DelSol starts looking like a CRX when you put a kamm on it...

Looks great! I don't think Lexan would be too far off for a good looking customization that would also improve aero substantially.
