Seems like the returns progressively diminish when going from the Z06 to ZR1 as compared with the C6 and Z06.

The paint color and rear spoiler look cheap. The back doesn't look distinctive at all. The fenders are nice, but I prefer the Z06 fenders. I like the raw carbon roof, and the front profile of the car with the new hood and wider fenders. The carbon brakes are a really nice touch. The supercharger sounds very interesting. Overall I'm very impressed they built it. Can't wait to see what kind of numbers it generates.

If they keep the 3.42 rear end, I am guessing the 6th gear will be about .75 which would give the ZR1 a 202mph topend at 6500rpm.

My 7000 redline would get me to 215.... so I would be able to play with the new kids at top speed as well

If they opt for a .71 then the ZR1 will be good for 210... and I would be geared for 229

215 sounds very good to me already. With that you can try very much harder at the track to find your next weakest link LOL.

Nice! Hopefully the power increase can outweigh the weight difference and give substantially better performance figures.

100 more hp should have no problem outweighting the 150 more lbs. However, why on earth do you need 19/20 inch wheels?...Put on a set of 18s and save urself 50lbs unsprung weight.

Why add a root type supercharger just to get 100hp? You could have change the cam and fine tune the air/fuel ratio and get more than 100hp out of the LS7. If they go the NA route, they would have maintained the perfect 50/50 balance instead of the nose heavy 52/48.

The price tag is absolutely ridiculous...90-120k?..Oh comeon. I bet at least 20k of the price hike is caused by the braking system. I don't see there is anything wrong with the ones on the Z.

Tom Wallace, vehicle line executive of Performance Cars, described driving the ZR1 as simply awesome. "It's fast and refined," he confided, adding that it has "a soft clutch, great midrange torque, compliant ride and brakes that don't squeal." He alluded to an expectation that the ZR1 would beat a Ferrari F430. Not just talk, as Tom races competitively. Pricing hasn't been announced, but we know buyers are lined up around the country. We've called the Z06 a budget-minded supercar, so the ZR1 is likely to be a reasonably priced exotic. We'll venture a guess between $90,000 and $120,000. And at that price, the performance is sure to be a steal!

Oh for pete sake, beat a 430?? At least aim alittle higher. He's more like dis-ing the ZR1 than prasing it.

Yeah, with the ZR1 at 620bhp, I will need to bump my NA 660 to at least 700 for a little insurance - as we know that many ZR1's wont be staying stock, and exhaust, pulley and ECU tweaks would eat up that 40bhp cushion I have in no time - plus they get PS2's as stock tyres *SHOCK*.... that means from day 1 they have big velcro hoops for tyres.

Now if only the C6 came in a fixed roof coupe hardtop profile instead of the fast back

I take it you are not too impressed with the ZR1 considering it is not a NA engine (wonder if they have track tested it for heat soak) and it is heavier than the stock Z06.

I wonder if they should have gone for a NA 8 litre lump or hotter engine tune instead of SCing it. I bet it would have been lighter option.

Not impressed at all (but the car looks sexy with those bling wheels and the news of Michelin PS2's stock is good) - but the SC was cheapest way they had to make a quick n dirty 600+bhp car and meet emmisions and fuel consumption needs.

Now Dodge didnt care (or maybe their fewer produciton numbers mean they can ignore the CAFE rules) as they just punched the V10 to 8.4 litres and called it a day.

There is a new Viper at MTI that they are playign with - stock its 600bhp translated to almost 560rwhp 540rwtq on the same dyno that showed my car putting down 580rwhp 508rwtq - so the ZR1 better bring its A-Game, this new Viper is a monster right out the box.

And I better find some NA HP quick to be able to park in the big boys parking lot

I have a few tricks up my sleeve arriving in January - so hopefully we will make the NA 700bhp mark and be ready for the new kids.

How much is a good cond. C6 Z going for right now?

Mid 50's to mid 60's still.

5vz-fe · 12-19-2007, 10:09 PM

Given in another year or 2 I guess. So any hint on your January upgrades?

*Points to the 15.5 " wheels one more time. Wont fit under 19s.

Point to the unnecessary 15.5 brakes

This car is aimed not at people who might cross shop between a 911 TT and the new ZR1 for a single car, but rather aimed at the well heeled enthusiast who will buy the ZR1 to put alongside his/her 911TT... so for $120 large, it s a great cheap 2nd super car

Plus it will most probably be one of his/her fastest cars hehe

Well I'm glad this car is a reality, but I'm not a fan of the styling. The styling enhancements on the Z06 work much better. The color is interesting, but it does not suit this car. The wheels are disgusting and too large and that front side vent is hideous. The rear spoiler looks like it was glued on, but at least its not some kind of wing. Overall I'm pretty disappointed, I think they could have done a much better job 'muscling-up' this ZR1. I was hoping they would go towards darker wheels as well, instead of these polished things. Honestly I'd rather have a Z06 and do some simple mods to the engine.

It doesn't look so bad in darker colors and non-chrome rims. Dare I say it looks good like this?

I just can't wait for someone to do a performance test on this car!
