Functional means FEA and Wind Tunnel time. Not enough volumes to cover R&D cost in my opinion.

:iagree: never gonna happen.
Now MAYBE computer testing... But even then, it'll only be a theory

Where's CSI and their magical enchance when you need them?

Can't wait to see these done as well as the other, more functional diffuser.

Poor Man's Wind Tunnel
 

One trick to test the functionality of a rear diffuser is to wait for a day with heavy rain and have a friend drive your car and you follow in another vehicle. As you follow, take a look at other cars on the road and notice how rain is being dispersed behind them (better yet, have another 370Z without a diffuser drive along side of the 370Z with a diffuser). You will see most cars on the road have sprays emitting from the front and rear wheel wells (not very efficient). Also take a look at how rain flows from the rear of the cars.

A functional diffuser will create a substantial rooster tail and should completely eliminate rain escaping from the rear wheel wells. My diffuser creates such a rooster tail that most cars cannot drive behind me in the rain

I created it out of aluminum flashing, aluminum plate, fiberglass and lots of pop rivets.

I need one these ... :tup:

Nice! I thought about making one myself but i have no engineering back round and i could probably make one that looks cool just not function very well. Good stuff. :tiphat:

any final pics on Res's car?

Sub'd:tup:

I bet no one else knows why the hell your car sprays water up like a jetski. Probably thinks you're an *******. But we know.....you're a badass. It's easily the most functional looking diffuser I've seen on a 370Z.

Do you have issues with curbs and slopes with that?

Guys relax on functional, just see when its done, we have seen similar diffuser on some cars not one of those good looking one but they were functional so we are just to replicate the same design on 370z.

Some work in progress pictures not a great quality one, spoiler is done design wise and so is the diffuser with fog light, finial finishing then we will make the mould. We will have similar diffuser with triple fins but slightly more aggressive.

Spoiler, more like a add on will be offered in CF and FRP

Diffuser, some cutting will be required to fit the foglight in the bumper

Sorry to jack your thread CarbonSignal. This is my last post in this thread. I promise.

And yes, I need to be very careful around curbs and slopes.

I hope you have one ready for my visit in July! I want to take one home. :)

So it's not a full wing, but an add on. One has to have an actual Nismo wing. Sorry, but I just lost interest. I was looking for the full wing.

:tup: Awesome, can't wait to see this!

I want this..
