Mikelly Posted October 11, 2012 Share Posted October 11, 2012 (edited) Gang, I had a member ping me offline and ask about the WindTunnel Video clips and OTHER data collected during this test. The WindTunnel Video Clips can be seen on Youtube in the links below: There are a large number of clips, so just search on that user name's account I created just for this test data. Any where there was a test issue, like hood latch popping or piece of equipment coming loose, we didn't post, because the test was immediately stopped. The Photos collected, along with the spreadsheet with the data, can be seen in my Photobucket Wind Tunnel Test folder located here: http://s145.photobucket.com/albums/r226/Mikelly_2006/Mikes%20Windtunnel%20Data/ Enjoy!

Tony D Posted October 12, 2012 Share Posted October 12, 2012 We all missed the fact that the G-Nose came with an undertray, streamlined the whole works back to behind the tranny! I'd seen sketches and knew there was a part number, saw my first one January of this year.... It would have made quite a difference, when you see the whole works together you realize how badly the reproduction G-Noses (one piece) handle airflow! Thanks for the ping and refresh Mike!

It would have made quite a difference, when you see the whole works together you realize how badly the reproduction G-Noses (one piece) handle airflow! Tony, The 'HS30-H' model Fairlady 240ZG homologation special - as sold to the general public - had exactly the same splash tray / under cover as the other L-gata engined models sold alongside it. You may be thinking of the FRP engine & trans under cover of the PS30-SB Fairlady Z432-R, which extended from the front valance ( which was made from FRP on the 432-R, and stepped to accommodate the under cover ) all the way back to the trans - splitting in two to cover the gap at the sides. It was initially part number 98200-E7200 on the 432-R in 1969, but later versions - tailored to the L-gata engined cars and rather more fancy - were seen in the Sports Option catalogues. The works race team of course used quite complicated and comprehensive ducting and spoilers in conjunction with the G-noses on their factory 240ZR race cars. The Fairlady 240ZG that was sold to the general public was essentially a base to build from.... Quote Link to comment Share on other sites More sharing options...
HS30-H Posted October 12, 2012 Share Posted October 12, 2012 Here's a scan from the factory parts manual showing the 432-R under cover / shield: Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted October 12, 2012 Share Posted October 12, 2012 Alan, do you have an image of the under cover / shield mounted on a z? I downloaded and printed the scan you provided and would love to see how it fits/attaches! Quote Link to comment Share on other sites More sharing options...
HS30-H Posted October 12, 2012 Share Posted October 12, 2012 Alan, do you have an image of the under cover / shield mounted on a z? Not the kind of image that's easy to find, really. Here's the best I can do for now. It's from the JAF homologation papers for the 432. Remember that this was not a stock part for the 432, but was a stock part on the homologation special 432-R model: Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 13, 2012 Share Posted October 13, 2012 Nice replica attempted to be shown here is 40,000 Yen from Car Shop Jalopy (Nisisan) He does nice GTR work as well! Nisisan and Okamurasan (my co-conspirator for 'convenient customer visits nearby') Quote Link to comment Share on other sites More sharing options...
Mikelly Posted October 19, 2012 Author Share Posted October 19, 2012 This will be fairly easy to replicate. If things work out as planned, I may schedule some more time in the tunnel early next spring. Hope to get Matt and Mark, and a few others into the session as well. Will have some improvements and "variety" of body mods on hand if we can. Mike Quote Link to comment Share on other sites More sharing options...
LowCarbZ Posted October 19, 2012 Share Posted October 19, 2012 Thanks for sharing this, I find it interesting and plan on possibly changing the under-tray on my ZG. Mind is a homemade variation out of aluminum that extends to the oil pan drain plug. Quote Link to comment Share on other sites More sharing options...
EvilC Posted October 22, 2012 Share Posted October 22, 2012 Alan - I just picked up a 76 Fairlady and quickly noticed this: I will get a better pic once I have the car on the lift but it appears to be a pan that was installed under the trans going towards to diff.

HS30-H Posted October 22, 2012 Share Posted October 22, 2012 Alan - I just picked up a 76 Fairlady and quickly noticed this: Congrats on the S31 purchase, Clive. I think the panel you see under the car is actually a heat shield rather than an aerodynamics-related device. The S31s had a LOT of extra add-on equipment, and were equipped with catalytic converters which left a lot of heat under the floor, and Nissan made a big effort to counteract this. Here's a couple of relevant pages from the S31 factory parts fiche. Sorry about the quality ( the original PDF is a bit better than my scanned images ) but the part I'm pointing at is numbered 74939, and is the 74661-N4300 Insulator - Tunnel Front. Cheers, Alan T.
