My next goal is to add a .64 6th gear. This is in an effort to lower cursing for MPG and increase top speed! RPM from a 2012 civic sI with following oem Honda part numbers:
24201-PNS-010
24210-PNS-010
24240-PNS-000
24412-PNS-000
24430-PNS-000
23916-PNS-000
23641-PPP-000
23491-RAS-000
23590-RAS-A00
91103-RAS-003

Instead of actually fixing the things that need to be finished such as the speedometer, and AC and temp gauge, I decided to get my priorities strait and attempt to improve fuel economy!!!
The entire under body paneling is made out of 1/8th dibond. It is comprised of two painted sheets of .012" aluminum with a solid polyethylene core. It is VERY durable, strong, lightweight, and once bent, it holds it shape. It can be picked up at any sign shop, and they will usually sell old or damaged sheets very cheaply. can be cut with any wood cutting means easily. I find it to be a much better alternative to coroplast.
They also make a corrugated version that is phenomenally ridged and strong for its size, But it much harder to find used or damaged.
Short road trip before belly pan It should be noted that the MPGuino is not correctly calibrated for the injector size. however, it is pretty close.
Aluminum bolted to to the factory air deflector on the fuel tank.
The panels are all held on with Stainless steel bolts through J clips either through factory push rivet holes or holes drilled in the aluminum brackets that I added that are bolted to factory points

The measured angle of the rear diffuiser is at 5.4 degrees, which is pretty close to the ideal angle in terms of drag reduction according to this paper

I have not finished the passenger side belly pan on the car, but all i can say is WOW. what a Huge difference, the car is MUCH more stable at higher speeds and road noise is greatly reduced. I have still yet to do ABA testing but i will keep you all posted.
It is Important to note that I plan on entering this car in 2 competitive Motorsport events namely the Texas Mile, and the Big Bend Open Road Race (120mph GT-3 class)
I have tein adjustable coil-overs and am waiting on some custom springs to be made. these are from a 2005 Civic Ex and should work with custom top hats. and at the moment, its the stock suspension.
My ultimate goal's are to hit 50 mpg HWY and be able to run 180MPH in the standing Mile (safely).
Currently (pre-bellypan) is ~40mpg hwy 145 MPH standing mile (gearing/stability limited) Pretty lofty goals, I know. but we will see!
