performancebox data, c5z vs turbo miata at laguna seca
1 Attachment(s)
My friend with a c5z was at LS with his performancebox on the same day as me and I thought it would be interesting to compare speed vs distance on our best laps.
His setup (blue line): c5z Long tubes with tune. Crazy wide CCW wheels with hoosier slicks Coilovers Driver mod. He's definitely a better driver than me. My setup (red line): 97 2554r on stock 1.8L with busted studs. The car was setup to do 14-15psi, but I was only seeing 11 in this session. ~190-200 whp. FCM Bilsteins 500/325 15x9 6ULs w/ nt01s I had to pick a common start/finish point so I picked the one that favored him. If you move the point back to turn 1 his time goes up to 1:40.X and I'm doing a 1:44.9. It was hard for both of us to get a clean lap. From watching his videos I can see he is doing a better job of using the whole track. - His acceleration is significantly better than mine. No surprise there. - He's getting on the gas a lot sooner in a few of the turn exits. - I'm a complete wimp in 6. - Something is funny with his data in 9. He didn't slow down that much after the corkscrew. Anyways, I thought it was a fun comparison and shows me what areas to improve the next time I go to the track. There's also acceleration data that I can graph if anyone is interested. https://www.miataturbo.net/forum/att...4226-photo.jpg |
I see what you mean in 6, but thats pretty good on your part IMHO. Thats not really a heavy car by normal standards (probably about 3400 with an average guy and the big hoosiers on it) and you had very similar apex speeds.
Circa 380WHP is a wonderful thing :) If you had another 30-40 it would have helped a lot (thanks captain obvious I know). |
I wonder if the G forces generated in the corkscrewed up your data logger momentarily. Wouldn't surprise me.
Can we see the derivative of that graph please? |
i may have to buy a performance box. Its the most attractive of all the dataloggers the more i consider it.

Mike, want to see something really scary?
Listen to the exhaust note through turn 6. Fast SMs are getting through 6 at ~88mph. :eek: |

Here's acceleration and lateral acceleration. It's a lot easier to mess around with this stuff in the software. I attached my last session in dbn format. The software can be downloaded here: PerformanceBox and DriftBox from VBOX USA https://www.miataturbo.net/forum/att...0&d=1266893650 https://www.miataturbo.net/forum/att...1&d=1266893650 |
Mike,
If I attend the Miata's at Laguna Seca thingy, you can put the box in my car for a session if you want to. I don't know exact apex speeds of turn 6, but it is a slight lift, back to flat before turn in, you hit 88-89 on a good run at the exit curbing. Both Yepez and I had the same professional coach, so we run a nearly identical line at Laguna. Sav, Don't ever again post a video glorifying Ypz! ;-) |
