Well with two hours to go, here is the update (as promised because I don't want to upset the Reaper Wink )

After two months (from our last update), we have finished so much on the car.



Here are our main items we finished on the car:

Air Intake: We finished the intake system and have the air filter installed and functional. The only thing we have left to do is build our side gill and build an air box around the filter. We should be finishing this within the next month.



Wiring: We did an enormous amount of wiring over the past two months. September was almost completely dedicated to wiring within the car. We finished wiring the controller for the air suspension, re-wired the entire interior of the car including a new fuse block for both the driver and passenger side, as well as integrating the engine controller wiring into the car. We also re-located the battery and moved the main power cable to the middle of the car. The wiring was a huge process that is now complete.



Fuel Tank: We got the fuel tank completely installed in the car including fuel lines, fuel pumps, etc. From our preliminary calculations, we calculated that the tank would hold around 14-15 gallons. After filling it with 10 gallons of fuel, it looks like the tank will be around 16-16.5 gallons. Very good size for our application. (Especially since the LS9 will get around 21 MPG on the freeway.)







Fluids: We filled the engine up with all of it’s fluids! Oil, fuel, and coolant.

Over the last week we got the engine started! We had an issue initially with the engine harness not firing the cylinders on the right side of the engine, but it turned out to be a connection issue within the harness. We got that problem fixed and then we decided to install the old exhaust system from the LS3 to get it fired up. After that bolted right up, we were able to start the engine, and WOW, this thing sounds great. Watch the two videos below and you will hear what I am talking about!

(At time of posting, the videos are still uploading. They should be up and ready in about an hour Big Grin)

Our last issue that we are overcoming now is an issue with our clutch connection to the engine. Unfortunately, when we first mated the engine and the tranny, we noticed an issue with the clutch disengaging. We recognized the issue and it was going to be a 50-50 shot if the clutch was going to disengage fully when installed. Unfortunately, the clutch does not fully disengage, like we had anticipated early on. Our next step will be pulling the transmission out, by itself, and swapping out the current throwout bearing with a hydraulic version that will have more throw. A slight monkey wrench in the project but not detrimental. We will get that changed out and we should be on the street in no time.

Once we have that issue knocked out, our last projects include finishing the air intake system, the intercooler system, the LS9 exhaust system, and buttoning up the interior including fabricating our new hatch cover. If all goes well, we should be on the road in the next month or two.
