CSX3170 Update

[Cobra #3170]

We did a test of 3170 last Sunday after months of work on it. It has fresh paint and the original bumpers back on and looks very much like it did when brand new. I did not reinstall the sun visors or wind wings though and the interior has racing seats etc. I have replaced the #16 oil supply hose and fittings, had new seals and O rings put in the Daily dry sump and replaced the
RH valve cover gasket and seem to have solved the oil leak problems. The electrical issues with the FAST system were solved by replacing the engine builders harness with a stock FAST harness. The tune is still way off because the builder just went for peak power and forgot about throttle response and proper air fuel ratios at partial throttle. We fixed about 70% of the problem but still have some flat spot issues due to lean A/F ratios. The smaller engine also needed lots more rear brake bias than the 498 because of lower internal drag. I have a short video of Scott trying second gear with traction control on and it actually worked fairly well. First gear blows the tires off because it still has so much torque even with 20 degrees of timing retard. The rear gear ratio is 4.88 with a 1.73 second gear. Second is good for 88 mph at 9300. It pull really well in second even at low speeds as you can see in the video. We are going to try some more tuning changes with help from FAST and run it next weekend. My fingers and toes are all crossed.
I hope this Google video works, never posted one before. Second gear pull with traction Control
