Do you think the Rival S tires would improve those numbers, Mark?
Indeed!!!
This makes me wonder, what kind of numbers did Hellfire generate once it was dialed-in? |
Tires and tire wear is a tricky subject. First off not all Michelin Super Sports are the same. All of the OE tires are tuned to the car. The 345 I chunked on Hellfire was due to tire over temps due to 100 MPH tire spin. I'm sure Ferrari works with Michelin to tune a specific tire. The Michelin tires on the C7 Corvette are very unique from the off the shelf tires.
On your bosses car, there is big difference batween 9/10 and 10/10 on tire wear and car temps.
Right now on Rival S tires I would say JA 2.0 is faster than Hellfire on the old Rivals. Actually I have data from Waterford that it is. I will know when I get to Gingerman. Most of my data is from Gingerman so it will be a better comparison. On a high lever JA 2.0is 125 lbs heavier than HF. JA 2.0 is up 20 HP over Hellfire so that is a wash. The Rival S is much better than the Rivals so it should be fun to see the lap times.
The graph below show the Rivals (in Red) from OUSCI last year on a 85 degree day on Hellfire. The Blue data is the Rival S on JA 2.0 on Gingerman on a 60 degree day.
The X axis is Lateral Acceleration and the Y axis is Long Acceleration (Friction Circle)
The data is kind of interesting that you can clearly see the max Lat numbers on the Rival S are up about 0.08 to 0.10 G in LH and RH turns. Because it was cold and Waterford is small the acceleration and Decel delta does not show up.
I know once I get the Rival S on a bigger track where I can get some heat in them they will really work well.
