Woot! Can't wait till the shakedown starts! Can't wait till I get home! My new motivation to get home! I may need to start off in another car... Speed limit is 24kph here... if your lucky enough to be driving.

It was put on hold because the original test car backed out and they have been waiting for someone to step up to fill the rest of the testing.
Best part is a lot of the work has been done, they had the kit on the car so it was more fine tuning by the looks of it. Making sure pieces fit properly, tuning, checking for possible mistakes.

You and me both... I'm afflicted with refreshing the forum every 5 minutes, checking my email inbox and scouring the forum haha. It's a test of patience and things are just getting started. I'm not sure what fine tuning still needs done, but my car will be with them for 9 months. They most likely won't need nearly that kind of time to complete it.

Other factors that may come up is my car is very very far from stock. Some of the parts I have do need to come off. The LTH's and full exhaust will reduce the amount of pressure running in the system and may have to play with pulley's, belts and housing sizes to find what works best for the application. I also threw radiators, new hoses, a Motordyne manifold, brakes, a lot of extra stuff. They can try a host of combinations that will help them anticipate what a customer needs with stuff I already bought. I even supplied a brand new resonator for my Y pipe, they can theoretically test the difference in power and back pressure between that and a HFC. It's not a 100% to having two resonators and HFC's after the stock header, but close enough.

9 months also leaves room for them to take more of my money haha. I could go for some strengthened internals and their traction control system. Not sure how the Wife would respond to that, so I'm just gonna leave the that alone :)

Your wife sounds like a very understanding and patient woman. Congrats on having an awesome spouse! Good luck with the twin supercharger project.

I updated this in my journal and my old NA dark side bla blah thread, which should be dying off as it has no use for me any more haha, but does have some good information for others to make a decision on. For any historical data on the car, just peruse my journal or look in my album at the dyno sheets.

Here is a pic of my baseline and the car strapped in. This was done within an hour of it arriving, and looks to be the first pull. So no ecu adjustments on it's own were possible by the time it was strapped.

This is where it get's fun. I linked an old dyno I converted in SAE done in March. STD and SAE are close enough. But look at the curves, dips, peaks. It's seriously exactly the same. Even the results are the same. Tuned and untuned results... exactly the same. These ECU's are a work of art.

So this confirms at least a good consistent snap shot of the car. I'm very sure there is extra bottled up in there that would make the graph look nicer, but it won't matter soon.

Congrats Firehawk! When all said n done, I hope u truly enjoy ur beast of a ride! Should be a smile from ear to ear!

SS_Firehawk 12-08-2012 08:22 AM

Thanks for the support! I still can't help to think of everything else I still need to do to finish out the car. But then, I'll probably think of something else.To afford it all, I might have to stay here another year and I really don't care to do that haha. If I can get my yard completed, floors done, counter top, some furniture, pay the cars off, buy a daily driver and still have extra money? Then the car can take more of my money.

I definitely measure my distance to that line as things go on. The Twin SC kit, or at least the cost for it to happen was already budgeted. I'm just happy I can actually bring to fruition something that used to be a dream. I think I checked my email and these threads like 100x hoping to see an update.
