Glad to hear...
If they stick to sheet metal/aluminum this could be done in hours...for those who have been underneat thier nismo knows what I'm talking about.

Guys, this project was originally delayed because of bad weather but has more recently been delayed because I have not had time to swing by the guys place that is making the mold. I have been extremely busy as I have a wife, 2 year old son, and work nearly 100 hours a week running a multiple companies.
This is going to be finished as it's very important to my cars goals. I have already asked if my guy would be available next weekend to do the next fitment test and am currently waiting to hear back after he checks his schedule. If I had to give a final time line on this right now, I would say a month, then another couple weeks to make the final mold.

Adding the opening for the exhaust on the diffuser will be one of the easier things to do..
Being that I have some free time now (I old one of my companies), I have the time to finish this car and get it back out to the track where it belongs.
You all are complicating things with the exhaust for no reason. End it at the differential and point it blowing over the fins and have a blown rear diffuser like Red Bull/Infiniti racing did in F1 last year and the year before that. FIA banned it because the other teams who also had them, sucked at life. http://www.formula1.com/news/features/2011/6/12186.html
Either way, we are kind of obligated to make a rear diffuser that way because Renault is our parent company and the FM platform is a Renault chassis.

What is a blown diffuser?
On road cars, the engine exhaust exits are normally located at the rear of the car. On a Formula One car they are deliberately located in front of the rear wheels so that the hot, fast flowing exhaust gases can be channelled towards the car’s rear diffuser. This increases airflow through the diffuser and in turn increases the amount of downforce the diffuser produces. This is perfectly legal under current F1 regulations.
What is an off-throttle blown diffuser?
Normally the engine will only produce exhaust gases when the driver is on the throttle. This means when the driver lifts off, the blown diffuser is suddenly robbed of the additional airflow. To get around this, some teams have modified their engine mapping so that when the driver lifts off, although fuel supply and ignition are cut, airflow through the exhaust - and hence to the diffuser -continues. This technique has become known as ‘cold blowing’ - the exhaust is still ‘blowing’ into the diffuser, but that airflow is now ‘cold’ since no fuel or ignition is involved.
