schill

Zander \Zan"der\, n. [Cf. D. zand sand.] (Zo["o]l.) A European pike perch (Stizostedion lucioperca) allied to the wall-eye; -- called also sandari, sander, sannat, schill, and zant.

I've been called a lot of things, but never a Euro-fish
Whatever. Rules of the forum:
1--don't double post the same topic because you can't use a search button
2--don't **** the mods off, or it's a 1 way trip to banville, no return ticket.
3--if by chance you pissed a mod off, and by his good graces he did not ban you, have a little humility instead of further pissing the mod off with bandwidth wasting drivel.

Don't just do it for me, do it the good of the whole miata world!
Will do. I will be installing the hood after class tomorrow afternoon and I will post results afterward. Scott if i could use your Magnehelic that would be useful. Im hoping for some good results!

Blah, driving is no biggie. Esp down south! Standing outside when its 20 and snowing trying to align a hood perfectly is another story...

Did the weather cooperate this weekend?

Thanks for posting pics. The gills definitely make the hood look more aggressive.

Ok here are the results:

I preformed some simple tests today to see if the gills work positively or negativly.

Weather conditions:
Partly cloudy at 37*F,
45% humidity
Pressure: 30.12 in / 1019.9 hPa (Falling)

I attached a piece of ribbon to each of the gills as well as the vented part after the radiator. The pieces of ribbon were 2" long on the right and 4"long on the left. At Idle the ribbons were limp as would be expected until the radiator fans came on. At 5-10 MPH the ribbons on the passenger side would be pushing out while the gills on the turbo side would suck in for just a brief moment. Im not sure as to why this was but I suspect it has to do with the intake sucking in air. From then on the ribbons on both side of the hood were pushed outward until 60 mph which was the fastest I was willing to go while staring at my hood. I will post a video of the findings tomorrow as well as pictures.

Some of the factors that might have effected the results were:
TSI's
Duel fan mod
No undertray
radiator cooling plate
and rubber trim from behind the cowl removed

Thanks 7guy!

pics and vids

However, you should see lower coolant temps if you slap on an under tray, ditch the TSI's, and replace the cowl seal. Each of these mods allow air to bypass the radiator and (slightly) decrease the pressure differential across it.

I don't think these mods will have a big impact on your test because I would have expected the the external pressure above the gill region of the hood to be much greater than what is going on under the hood. Looks like that is not the case.

Pics and vids to come soon. I would have an undertray but the mounting spots snapped off while i was putting on my intercooler and it wont stay on anymore :(

Plus I like the look of the TSI's....

Not that anyone here cares as the subject has drifted , but the GB is now closed.

I will be doing some high speed aero testing with a windshield mounted video cam + the "tuffs of yarn taped to the hood" method in order to gauge the best location for exhaust side venting of the radiant turbo/exh manifold heat. I found a couple websites with kickass selections of drop in vents in several material types, including CF so I will have no problem making it look decent, but more importantly more functional than the gill vents of the 1st gen autokonexion hood.
