Reply to "Ground Effects"

Hi Goram,
I am wondering why you do not mention a rear ground effects underbody panel for the Pantera. I asked the question about Pantera ground effects in Pantera International Bulletin Board's (PIBB) Forum "Technical Advice and Questions" at the end of last week, 3/10/05, and there has been 398 people viewing the question and answer session in only 4 days. I'm "veryfast italain" on the PIBB and Ron Norman, in real life, living in Albuquerque, New Mexico, USA.

So, my idea about the rear underbody ground effects aluminum pan is being asked there, and I thought I should ask you if you would like to join the PIBB topic, as I've seen you do in the past. It will be nice for me to be able to learn more, and many others are interested too. Please join the PIBB discussion topic if you'd be so kind. I also read your Pantera International article on tire sizes a while back. Recently I wrote an article published in Pantera International too. Please see it on page 15, Summer 2004, Pantera International, if you like.

Thank you for the very detailed and informative website. You may see more visitors son because there is a link to your website in the topic: Ground Effects on PIBB.

Maybe it will be interesting to develop this idea further, and we will certainly be checking your website in the future as you develop your Pantera even further. I'm inspired by your project. "Way to go", Goram.

Best regards,
Ron

Ron, nice to hear from you.

Well, I have had some troubble connecting up to the board, and also asked Dave for assistance.
But it failed and I hasent tryed since then. May check it up again. I do have an article comming up
in the PI magnext issue about shock absorbers. And another one about spring and bar settings
for race cars, for futher issues.

I havent bee sleeping when it comes to rear diffusser;s. But the big problem is the Pantera rear
layout that dosent easely accept an diffusser. First, the frame where the rollbar is fasten, is right
in the way for the expansion roof. Even the A-arms is a bit of a problem, espesialy if rebound is
extensive. We must also se to that the engine compartment get some cooling air if the entire
underside is blocked.

If you look at the underside of the car, the cockpit floor is not flat. Neither is the rear frame "inline"
with the floor. We will run in to som strange stepped underside which is not very good. I was planning
on making a whole new lower rear frame, to get it where it out of the way. The front part all the way to
the engine is allready quite functional, which is the area to start working with.

The rear hood has a flat floor which is feed with air from under the car, comming out the "fake window".
Its a turbulent area, and the lack of "wingshape" due to the hood -flat area does not create any rear lift.
However, the diffusser must be made to work together with all these conditions. Ok, a lot guesswork
here, but things to take in to account. And a few things mentioned I also know for sure.

Whatever way we look at this problem, it is NOT a fabrication bolt on part. If not som sort of
"semi-functional-bling stuff" is asked for. But I dont involve myself in such things.
Allright, we will see what to come up with.
