I heard this beastly sound and the whine of a SC all at once and there went a Dark blue/black New Vette. Could not tell if it was a ZR1 or a modded late model, but it was loud and mean. On Wildcat reserve near Broadway.

 

no one has seen this beast in Highlands Ranch? They must have just got it then.

 

I'd love to run one of those....

 

Have you run a ZO6 yet? think of the ZR1 as a ZO6 on steroids. There are very few cars a ZR1 will need to worry about. I can't wait to roll one as well.

 

When I was at PPIR with NASA last fall, there were 2904823904829034823758942308523 C6Z06s at the track. Like bunnies. Everywhere.

So the last run of the day one of the C6 Z06s and I were in line. For a few laps around the track, I was behind him. We were running with a group with two passing zones -- front and back straights. He wouldn't wave me by even though I could easily take him coming out of the back turns onto the front straight. Finally he did and he was kind of behind me for a couple of laps, but any time there was open space, my lead on him became gigantic.

So after the session, I found him and asked, "So your car is stock, right?"

And he's all, no it has mods.

I was in shock. I felt bad for all of those C6Z06s owners.

 

you forgot the commas, haha. I think the altitude really hurts ZO6's out here. They have to have some serious mods to keep up with a 996tt with a tune. But a ZR1 having a compressor of it's own will not have that disadvantage. So it should be interesting.

 

Hmmm, the video of it running the Ring should say something. Of course it wont be the same driver, but the cars potential speaks for itself. It does hold the second best time of any car out there... behind the new ACR.

 

actually a street legal Edo 996 turbo holds the record at 7:15, but it isn't stock.

 

Sorry. I thought it would be obvious we were talking about stock cars.

 

yah, I guess the ACR with AC delete and race setup is a stock car.

but you are correct, the ZR1 being all stock may just be the fastest stock car around the ring. for now.

 

Ummm yeah the ACR with the "hardcore package" is a factory option and it is a stock car. It comes from the factory that way... why wouldnt it be stock????

And with the economy the way it is, car companies may not push the boundaries too much anymore. Especially the US automakers... since the government pretty much owns them. We may be at the end of the horsepower wars... hopefully not.

 

no it truly is a factory car, kinda like the days when you could get one of those 50 hemi cudas with aluminum heads and 12.5:1 compression. AC delete on any car does not make a road car. But it is stock.

I hope we are not at the end of the hp wars, and I hope that we are also not turning socialist, as gov owned would imply, since that would mean socialism which goes against the very foundation of this country

 

Riot! + reps for you!

 

Driver is the biggest factor at the track. The C6 Z06 is a somewhat challenging car, when it comes to pushing the performance envelope.

I don't put too much weight on relative performance at DE events. At a Pueblo lapping day last year, I was able to tag onto the back of a 997tt for many laps in my Evo. I won't say it was skill, but perhaps more willingness on my part to move up the risk curve. On the same day, an E36 M3 with suspension mods was outpacing me even though my Evo was significantly faster on the straights.

 

The supercharged ZR1 will still have the altitude disadvantage. There isn't a way for the supercharger to compensate for the lower atmospheric pressure the way a turbo can.

The turbo wastegate won't actuate until the maximum absolute pressure is attained.

Atmospheric Pressure + Boost Pressure = Absolute Pressure

For example, if atmospheric pressure is 2psi lower at altitude, the turbocharger boosts 2psi higher to achieve the same absolute pressure. Of course, there are limits to boost pressure increases due to the design of the turbocharger. There's a point at which the turbocharger will be making more heat than boost.

Superchargers have no similar way to compensate for the lower atmospheric pressure. There's no way supercharger boost can be increased on the fly. As such, the supercharged motor suffers from lower atmospheric pressure in a similar way to a normally aspirated motor. You just can't swap to higher boost pulleys on the fly to compensate for changing atmospheric conditions.
