Internal Body Aerodynamics

Pappy -
As always, NICE work.
Just a tip: a pretty good Rule of Thumb on Radiator Duct Design:
Inlet area 1/6 area of radiator surface area. [From Walter Korff]

I suppose that is something that can be "trimmed" out - which is how I'm planning, a bit of foam, test(?) then 'glass in the shape. Nice catch on the leading edge "lips" on the Camaro's radiator "snorkels" - a nice homage to Dan.

Cheers - Jim

Thanks Jim,

I have a secondary divider (yellow) in the grill area in front of the radiator that diverts a portion of incoming area over the radiator and into duct work that goes to the TB. That divider is adjustable vertically, so it can be used to trim out the amount of air flowing to the radiator core.

At 11:00 he talks about his radiator ducting.

One more.

A bit old and only has 1600 views, but sort of interesting.

I guess with the lower speeds involved, he figures the big spoiler on the back is more effective than a wing. It would be interesting to see the downforce/drag vs mph.

These guys post a lot of stuff on their product. One looked at radiator delta p.

This one looks at fender vents, but without the pumping effect of the tire it might not tell the whole story.

^^^^^^

Good point.
 
There is some information to be learned with a rotating wheel in the case - for sure. NOTE: the effectiveness of the wheel "Spats" on the flow around the wheel in any case. With the addition of air curtains - some significant evacuation could also be effected.

Also, with the open fender (at the rear - popular TimeAttack and prototype layout) there "might" be enough pressure differential to diminish any effects from a rotating tire. [I'll need to look at some other tunnel/tuft studies information to confirm that thought.]

I stumbled on the racelouvers.com site a while back and haven't had time (damn boat) to get through the pages of data they offer; Here is a quick look at the drop down menu:

Enjoy! Lots to be seen there; cooling, fan shrouds, louvers, gurneys, etc.

PS - I note the "earliest" Corvette served is a C4!

This guy has dozens of these.

This car is for sale, and some spent some money ( blower etc. ). But I think the wing is backwards. Good price actually.

Not sure if this is just a computer rendering or a real kit car.

No joy on TinEye... Who's posting? Some interesting aspects there. But, a "helper mirror?" Also PAX Side louvers look "Off."
Oh - found it! It is a "Rocket Bunny" one-off kit. (But listed on renderings pages- hmmm)

Rear fenders and skirts are a lift from his "Smurf" Linked at the Auto Evolution article.

I think the concept is pretty good. One of the better looking c4's I've seen. Probably the biggest aero benefit is it covers extra wide wheels.

I like that, looks retro and modern at the same time. Stock C4's are pretty tired looking these days.

Is that a concept or an actual car?
 
There is this "version"

AT this low angle shot - kinda reminds me of the Fiero. This is a "special order" kit and is $3150. No idea of quality - just looking (and curious too).
Just guessing - but at that price bet it is fenders, side skirts, lower bumper - and maybe the wing? Front fender flares are more a "traditional look " and not the SpeedHunter versions on the "Bunny." The rears have a cut-out, however:
