PRE-Z06

I remember a bolt-on C6Z06 going 9.9, so I expect it to match that.

It better do a sub 7 second. We already got blue ***** from GM about the z06 not making an official lap time. A car that's their golden child when it comes to track times and we don't even know what it can do.

Meaning the GTD mustang is set it's target at porsche and people are hoping it does 6:4x.

If it does that GM should be ashamed of themselves.

Mr Trifecta!

The Mustang GTD will not do a 6:4x! Neither will the ZR1, however, it has a better chance with active aero. It's hard to fight physics, you know that 2 ton weight!

No doubt at MIR in the winter.
IIRC, under 10.5 was rare air for a bolt-on C6Z06. Took a fair of amount of skill (driving and car set-up) to get those times even in mineshaft weather.

I don't think it will either. Just relaying what people are hoping for. Every video comment section where the GTD is showcased, people are saying this will beat the GT3RS time lol.

Like that car is the master. You don't just show up and act like you're going to take down the master. Not even corvettes can do it and they're the most capable cars you can buy today without having to sell your house and corvettes can't even get close.

Bruce went 10.3 on a 1.45 60’ with stock 3.42 gears in +1k’ DA, but he can definitely drive…

I think the HP is a little high I'm thinking 800-850hp. But in any case the issue for this car will be traction with that much HP/Torque and not being AWD.

There were/are a fair number of SBE C6Z06's in the 9's
One example. Takes a very good driver, but 600+whp on stickies in a (relativity) lightweight car = fast.

I'm going to disagree on both counts...the only basis that typically has been used to estimate power is the original leaked ZERV info that was published and picked up by people like Haggerty when they post this chart below where the Z06 was estimated at 600 HP and it exceeded this by over 10% to 670! I'm postulating that the same case will hold for the ZR1 and that 850 EASILY turns into 900 HP (or more) since we're dealing with a 3900+ lb pig with driver.

On your second point, yes, traction will be a concern but no as much as people think...why? The C7 ZR1 had a 52/48 weight distribution whereas the ZR1 will likely have at least a 40/60 split (depending on how the turbo plumbing is distributed) thus placing SIGNIFICANTLY more weight on the rear tires....when you combine this with likely ~100 lb/ft of torque less at low RPM (see chart below), the car literally should launch MUCH BETTER than the C7 ZR1 out of the hole since the guys are getting 1.6x on the stock C7 ZR1's! Plus, the Zr1 will also benefit from a larger tire width as well, 345 vs 335. All in all, the ZR1 should be a true engineering and track masterpiece!

with DRs the Zr1 will run 9s .

On the street w/RWD and stock tires 0-60 will be 3s just like a standard c8 , z06 or ANY RWD car with stock tires. They don't get faster on the street without AWD. Simple.

Every Mod I made to my GTR it clicked faster 0-60. Every Mod you make to a RWD car it stays the same +/- a tenth. The Zr1 could have 1000hp and it will still DragY 0-60 in 3s .My 23 z06 with a whopping 460Trq spins ..

Makes you think about how much quicker the C8Z06 would be if it could shed even 300 lbs.

@PRE-Z06 raised the idea of a bolt-on C6Z06 being in the 9s. I'm not aware of anyone getting to 600 RWHP with bolt-ons. Heads+Cam are a different story.

acroy

Agree on the weight reduction. I was really expecting/hoping the C8Z would shed some weight similarly to the C6Z with carbon/magnesium/aluminum bits. Not this time.
'Bolt on' is a vague term and I don't mean to start an argument here. I generally consider 'bolt ons' particularly on the C6-C7 platform to include heads/cam, as it is very common, engine stays in car etc. Something a reasonably competent home mechanic can do in the garage w/o a lift etc. But no FI, no Nitrous . Heads/cam on C8 would require engine out IIRC; not 'bolt on' at that point.

LMR's stage 1 package consists of eventuri intake, high flow cats and PTB's. They call it their 730hp package. (not WHP). And that's without a tune so i suspect when tuning becomes available for the C8Z, some nice gains can be made to just those 3 mods. Not bad for an NA car. But i would never modify this car. Not worth losing warranty over.

Those don't require an engine out however from videos i've seen, all those mods is easily an entire day's worth of work.

I recall bolt-ons as not normally touching engine oil. Things like headers, ported IM & TB, underdrive pulley, exhaust mods, and gears. PCV mods and catch-cans seem to be the exceptions. Cams and modified heads went into the next class up. Maybe that's changed with the C7.
