In F1 they use a water based paint type of fluid to see how air flows over different parts of the car. Might be worth a try.

As I keyed the above

I was thinking, "EGT is not going to work here." Then I found this:

High Temperature Infrared Temperature Sensor

These temperature sensors cover ranges up to 1200 Deg.C. The housing is manufactured from aluminium and is supplied in anodised red. This sensor is especially suitable for brake temperature measurement.

that sensor could be used to log directly on my traqmate I believe... will put some thought into it

good discussion all... these ducts have their trade-offs, but overall i think they will add to the reliability of the car which matters plenty to me... not too mention they will look good!... maybe not the most practical selection I've made, but we're moving forward with them

I like the idea of getting some measurement on the aero impacts... back in the day, had a wind tunnel at my engineering U... now, we're going to have to improvise... the fluid idea is a good one... I also know a few aerodynamicsts that I may check in with

Honestly at the level of racing that we are at I dont think they will have a noticable effect at all. You guys are talking F1 stuff and we are more of a DE type of level. I am not going to post any more pics of the car and cage but here is one scoop almost finished. I think they look bitchen! Super car style.

wtf ! ? we're not getting picked up for koni challenge ?

If you go there, I'll have to put on my GM Proving Grounds shirt with "Greg" name tag stitched on. It is in mothballs now, and it is still smoking. Last worn during fuel tank testing...no, I did not wear Nomex! Sometimes, I can't believe I'm still here! [insert flame smilie here]

Raison d'etre: "...they look bitchen!" My point exactly. Even if they don't work, Travisjb, Fathead's scoops will be the only ones at the track!
Can you spell "Psychological Advantage!"

Just pass one newbie on the outside in a 45* drift, pedal-to-the-metal, both rears throwing smoke and rubber chunks, front-end crossed up like a motorcrosser...and as you gain traction they will see the SCOOPS!...they will think you are a Z God!

if we want a real psychological advantage, will need one of these !!!

Is that Radial Machine Gun mounted on a Bugatti Veyron? NICE!

You would have to buy Koni suspension first.

Travis I just subscribed and am wondering if you are going to put a big $&@ gt wing on your car

hey, thx for your note.

yes, I will be pursuing more rear downforce. combo of rear wing and rear diffuser. if you look back a page or two, you'll see a kognition rear wing I am considering. as for rear diffuser, that is also a possiblity, but I'll probably wait for the market to produce one vs making a custom. one like the top secret model for 350s that is said to have a real aero impact.

The course I typically run has a nascar oval that I want to be able to run flat out. Speeds now are about 120mph... when I'm done, should be up around 135mph. And I want to be able to do so well within the margins of the car, so I don't end up eating concrete!

We're also looking at options for a front splitter. That WILL be custom and made of some relatively inexpensive material such as di-bond or hdpe.

What about the sunline Z body kit
