I remember talking with a patient in the marines and in the early 90's the wings on some jets that landed on carriers had tiny pin holes pressurize to help smooth the flow for super sonic speed.

cool idea

I have allot of those shows and would love to check it out.
Not sure which episode it was - my HTPC just recorded it off one of our local channels that's showing old Fifth Gear shows in pairs and their TV guide didn't say which episodes.

A quick bit of digging and I'm pretty sure its either the one with the Mercedes R-series review (S8E06) or the one with Nissan 350Z vs. Audi TT Quattro Sport (S8E07), as I saw both while watching the recording last night. Will check my other TV archives to see if I can confirm, but I deleted the captured program off the box after watching it.

Little bump- I'm playing around with a free (yes, you probably get what you pay for) app on my Droid called aDyno. I'm trying to feed it the variables it wants, but there are some I don't know.

http://adyno.net/forum/



Pitch characteristics: Change in pitch angle at 1G acceleration (gives a default of 2 degrees/ G. I find the expectation that anyone would know this laughable, but is the default reasonable?)

Roll characteristics: As above, but he default is 2.5o per G

Weight (3505 lbs empty on Greg's scales)
Additional Weight: 320 lbs (me + 100 lbs of fuel (3/4 tank)

Drive train losses: 15% default

Drag coefficient : 0.34, should it be 0.36 for a GTS without flaps?)

Frontal area: 1.951 m2


Thoughts on pitch and roll characteristics, given 18" 30 series tires, stock springs, Bilsteins, and 170ish / 160 ish ride heights?
