Great video - thanks, John ! The Z06 done good !!

More HP/Weight makes up for poorer chassis / handling every time. The Z06 has a lot of HP and low end torque. On a short tight track that can be a huge advantage. The other car with high HP/Weight and good low end torque, is the Lamborghini Huracan with that big V10 which had the best time.

In all the discussions of ME vs. FE, it is assumed that the ME always has an advantage, but that also assumes equal HP and flat torque curves. For a real world example the Ford GT, a mid-engine which has a sophisticated race car chassis but “only” 650 HP is slower at VIR than a 755 HP front-engine ZR1 with a (good) street car chassis. Mark Donahue once said a LeMans car had “sufficient” HP when it could light up the rear tires all the way down the Mulsanne straight. He almost got it with the 1300+ HP Porsche 917-30.

That is why i’d love to see the C8 ME with either an LT4 or LT5 engine. Despite all the interest in a DOHC, twin-turbo engine on the horizon, there does not appear to be much, if any, advantage of these “sophisticated” engines over the current DI supercharged small-block, except (perhaps) in fuel economy.

tread pattern means very little. People tend to be visual so assuming correlation is natural. The tire compounds are now specific to the r&d of these vehicles. That’s pushed further by porsche and these Cup R’s.

Bike mags will test with a control tire which makes things nice and clean. They also allow for suspension changes to deal with diameter and carcass stiffness deltas. Easy to do on a bike.

i do think you’d see some strong pushback from manufacturers in the car industry if trying to do spec tires. You’d likely be better off getting some of the popular youtube personalities putting on a shootout with a pro driver and spec tires. Now that Hoosiers come in many sizes, that’d be a good choice. It’d also take away the excuse for any manufacturer claiming their OEM tire is better.

The GT is a terrific race car. Race car developer/builder Multimatic designed it to be such. Costs were of little concern. Chip Gnassi developed the racing version of the Eco boost engine over a multi year program in ALMS/IMSA P (prototype) class. The GT is pretty much a prototype race car that was later modified to meet street safety requirements. It was given a waiver to race before the homoligation rules were satisfied. Look inside the “cockpit” of a street model... most normal size driver and passenger shoulders are touching. Virtually no seating adjustment. Luggage capacity is approximatly one basket ball (behind the mid engine). If a ZR1 ranks a 5 of 10 for being a practical street car, the GT is lucky to be a 1 IMO.. that being said, Id love to have one in the garage with the ZR1.
