Thanks for the back-to-back dyno comparisons. Our OE intake is really well thought out, and I've long since believed that short ram intakes that are open to the engine bay are nothing but noise makers, and that any dyno gains would disappear once the hood was closed.
Interesting observations on the Koni shocks as well. I've alternated the fronts between full soft, 1/2 turn and 1 full turn over the years, and settled on full soft during the winter months, since they otherwise seem to hit harder when it's cold, and 1/2 of a turn when it warms up. Any more just seems to be too stiff, which I'm sure is exaggerated by being lowered as well.
The shock dyno does seem to support my impressions that the Konis, especially on full soft, didn't degrade ride quality.
Nice build thread, and clean G

Thanks for the compliment! Regarding Koni, I am still playing with the settings at the track. Last event I ran them in full stiff, and the car understeered a bit. Now that the front bar is smaller, something tells me that I will be playing with the shocks to keep the rear planted. If I decide to continue in Street class next year, I might even get Konis revalved, and have them match the OEM Sport shock valving at the softest setting, and make full stiff something ridiculous to keep up with demands of autoX
Do you remove the shocks to adjust the rears? Accessing them isn't the easiest thing to do, hence why I haven't messed with them in years.

You'd be a pioneer in getting the Koni's revalved, unless someone on the 370Z board has gone that route. Only a handful of Gs on Konis.

After missing a few rounds due to either being sick or away on vacation, I was finally back in action last weekend during Round 4 of SCCA SoCal regional championship. The field was much smaller than usual (100 cars instead of 150+), but I still had another car to compete in the class with me, which was a 2016 Camaro SS. I realistically know that at the moment I am not the pace setter, since this is just my second event, so if I were to win anything, this would be the best opportunity I would get all year. And that's exactly what I have done. My first class win.
The takeaway from this round of autoX:
1. The sway bar swap helped. I went form a really stiff Hotchkis 35mm bar to a softer Eibach 32mm bar in stiff setting, and it has paid off really well. I could feel immediately how much more traction there is in the front and and rear didn't feel too compromised either, so I feel that given the stagger of the wheels and tires, I've achieved the optimum balance for something that could be done with off the shelf parts.
2. Driving style improvements. I've asked an instructor to ride around with me, and one thing I worked on this weekend was turning in sooner. Much sooner than I thought I would have to. Learning how to do this helped me to keep the car more under control and increase the speed as I'm going through slalom, rather than play catch up with the cones and lose speed as I'm going through them. There is definitely still a lot to learn, but I'm truly excited about the progress I've made so far.
