Oh, I agree completely. I didn't mean to imply I was comparing my car to your car directly, though it certainly reads that way. I skipped writing out a couple intermediate steps of getting a performance delta of Re71R vs slick with regards to corner speed and then seeing if I could apply that my car to come up with a ballpark since I can find lots of slick data but not much recent street tire data. Though, I suppose to be accurate you would need the same driver and car on slicks and street, so maybe it's wasted effort and I just need to go faster.

Thanks!

Wait, is a RE71 a R tire? That's how far I'm out of it I am these days. If so add a few mph.

Jim, 96 min @ 4 with street tires in a 964!
Damn, no wonder I am so slow. I poop my pants if I go through 4 at 95 on fresh Hoosiers.
You need to get out more

Yeah those are guesstimates but subtracted 4-5 mph from my target R7 speeds.

Agree. Hope to get out more next year.

RE71Rs are technically street tires. But they drive like amazing R-comps!

As Lara said, it is technically an ultra-high-performance street tire. However, it's basically on par with Cup2, NT01 and R888 tires.

From what I've heard, Hoosiers are ~1.5-2 seconds faster per lap than RE71R/Cup2/NT01/R888 at Summit Point Main; and Pirelli slicks are ~1.5-2 s/lap faster than Hoosiers.

According to the speedometer on my car, on my better laps, I'm apexing turn 4 at 103-105 mph. Not sure how accurate that is, but it agrees with the 1Hz GPS readings in HLT.

You can apex faster at T4 by not bothering with T5 and heading straight into T6. Takes nerves of steel. Also, you have to 'hop up' right before the wall there and do you best not to knock over the flagger's cooler.

Pretty sure the last thing Bill expected when he posted this was to be schooled

Are you aware of how Turns 5, 6 and 7 came to be? The story is Bill Scott was sitting in his office one day, watching cars on the original track layout (straight down the hill and turn right about where Turn 8 is now). He soon realized that any car that lost brakes coming down the hill had a reasonable chance of continuing on and driving straight into his office. So, he decided the track needed to be changed to minimize that possibility.

So it's your turn to be schooled.

Although, TBH, even though I heard the story from a reliable source that actually knew Bill Scott and probably heard it first-hand, I have not independently verified the story so can't validate its veracity.
