Yea my thought process is if the sc3r's are the best they should have made them in the right size and slapped some on the z06's and zr1's.

Agreed. I wish they would end their contract with Michelin for the Corvette line and move them to Goodyears.

I have always liked the way Goodyear performance tires feel over Michelin. They are just more responsive with stiffer sidewalls.

And with the SC3 and SC3R tires, Goodyear has really hit it out of the park.

The ZLE is a no compromises track beast, and I would bet a far larger percentage of them actually get tracked compared to 'Vettes. Even the SC3 non-Rs on the standard ZL1 are not particularly good street tires, so I'm not surprised 'Vettes come with Michelins instead.

Pretty sure it has a lot to do with IMSA and Michelin sponsorship there than anything else for the Corvette team.

That said, Michelin Cup tires out-performed the Goodyears for quite some time until the SC3Rs.

Cool stuff, nice to see the Demon getting it... I guess just as relevant to this is that SpeedPhenom ran a 10.9 on the street in his c8.

Just because I think I remember there being lots of C8 Z talk in this thread.

MT is predicting the C8 Z06 FPC will be TT and be 4.2L

The word I have been reading is a FPC DOHC 5.5 NA high rpm version of the 5.5 FPC DOHC NA motor that is operating in the C8 R and putting out 600 horse. No TT has been mentioned for the ZO6.

That was pretty much the same thing I had heard. That was why I was a little shocked to see MT suggesting a 4.2L TT and that article was published yesterday so its not like it was an old article they just threw back out there

I think MT is tracking down the wrong path on this one. For one thing, C8.R requires homologation, so that 5.5L NA FPC has to go somewhere. Second, when I listen to all the videos of camo- Z06 mules, I hear FPC. What I don’t hear is turbo whine. There is little doubt that ZR1 will be TT. Right now I’m tracking that as a 5.5TT, but it could arguably be 4.2TT. I agree with MT that the turbos will be outside bank, not hot V.

Doesn't make much sense to me, why spend all that monday developing a new engine, only to have it be forced induction with the same hp as the precious gen? I get its a completely different design but it ends up with the same result albeit with a different powerband. Might as well just thrown the lt4 in it.
I get the reported 5.5 because then at least it's pushing 600hp naturally aspirated.

That is coming from I believe the early reports of the cadillac 4.2 liter TT Blackwing motor . Cadillac Has the turbos in the V and corvette was supposed to have out board turbos on that blackwing design motor. There was talk of a 5.5 liter version of the blackwing TT for the higher horse corvette ZR1 something like 800 horse with 200 horse electric motors creating a 1000 horse monster. Cadillac has vowed not to share that blackwing motor. Corvette Racing is doing all the R&D on the 5.5 liter NA motor as they are currently racing the C8R and having great success with that NA set up..

GM has had plenty of time to check out the German hot-V V8s, and they are surprisingly efficient cruising around for the ridiculous acceleration times a lot of those cars post. And IDK what Caddy is even up to these days, seems like there's a major change of direction happening and there's no guarantee there will ever be a Caddy with the Blackwing V8 they swore wouldn't be shared.

I hope the C8Z goes back to NA though, ZR1 w/ turbos and Zora with turbos + electric motors. But who knows at this point...

Caddy already blew there load on the very limited productio CT6V blackwing TT 4.2. Very few cars built and no more to be built and no future use for the motor, what a waste. I do realy believe the C8 Z06 will be NA 5.5 DOHC FPC, and it should be IMO, or maybe that will be the GS????.
