hahah... things are moving a bit slow right now, which is okay b/c I'm waiting on a part from Nissan and the car won't start without it... In the meantime, a few announcements:

- I want to highlight some great service... Lou Fusz Nissan has been tremendous in helping me locate and obtain the main wiring harness for my car... it was buried deep in some production facility in Nissan Japan, and it is now on the way to my house... so, THANKS

- Forged Performance is the first to run the Aeromotion R2 on its 370z racecar build and I'm going to be following in their footsteps... read more here: AEROMOTIONS R Series and here: Aeromotions R2 Dynamic Wing - The Tuners Group

- Car is with Junior and I understand he is making good progress on some smaller projects... he may jump in with an update, otherwise, I will update again in a few days

Active Aero, I love it!

That wing looks pretty cool. They have wanted to use that type of thing in F1 forever, but can't because of regulations. So the question has to be asked....how long before they ban or outlaw it in TA series racing?

They usually only allow it in certain classes. For example RTA allows it in Modified and Super Modified but not in Street or Stock. In other TT events like those by NASA, they have a point based system, but the current rules make no mention of "Active Aero", so you simply take the point penalty for replacing the rear wing (+4). I'm sure that will change over time.

Travis are you ever going to add cannards to the front ???

I'm aiming to eventually be competitive in modified RTA... currently also in NASA TT but classed as TTS which is beyond the points group and for TTS aero is unrestricted so long as you do not violate a "tech rule"... in fact, we're discussing it here now as it pertains to windows: Are these legal - NASA AZ I dont' recall hearing about any current exclusions for active aero in NASA TTS, but that may change in the future, as was stated

and just to clarify, I'm initially ordering the "static" r2 model, and may at some point in the future add active computer controlled actuation... I suspect the 370z racecar Sharif is building will be full active - he can confirm

already on... same as you can see on the robispec car... these are more about creating vortex to avoid drag in a high speed turn is my understanding but others can comment that know more... regardless, they look cool!

My understanding of canards is that, unless you have a really powerful car, they will hurt more than help. They create a lot of drag and only cars with a lot of power can muscle through that drag enough for the added down force to be beneficial.

This is how it was explained to me when I brought up the idea of canards on my 05 STi to some time attack folks.

you may be right - figured I'd give them a shot... at some point, I'll try running with and without and will make some observations on car feel and lap time... if you're right, then I'll put them up for sale

you've probably all seen it, but I like this car so much I had to post here... sure wish this was going into production... at least they will make a track-only version!

theDreamer · 01-18-2010, 08:59 PM

What is the bylaw they found to get it into the races? The rule state the car must be in production to race, but this car will never see production (supposedly).

you have a point what I say is travis take off the cannards until you upgrade your engine or have a low speed turny track

For GT500, I found some mention of corresponding road-going variants, but no idea how many are required nor whether that is strictly managed... I do know that Honda says they will compete in this category, however!

The loophole is that they can state that the car is a continuation of an existing or previous road going model, doesn't seem to matter how different the car is.

I thought about that later, but then in my mind it is a completely different vehicle from the ground up. If they kept the engine placement (mid-engine) or something I could see the argument, but this car is nothing like the original NSX.
