Z06 vs. ZR1 - Power to Weight Ratio
-------------------------------------

Just for fun I did some calculations on how much HP a Z06 needs to have the same power to weight ratio as the ZR1…

Stock:
ZR1 – 3350 lbs, 620 hp
Power to Weight Ratio = 5.40

Z06 – 3130 lbs, 505 hp
Power to Weight Ratio = 6.19
-------------------------------------

So, if we mod a Z06 with some Headers, tune, intake, t-stat, ported t-body, we should get about 570 to 580… Depending on the tune and dyno… Cost $4K

New Ratio:

Z06 – 3130 lbs, 570 hp
Power to Weight Ratio = 5.49

Z06 – 3130 lbs, 575 hp
Power to Weight Ratio = 5.44

*** Z06 – 3130 lbs, 580 hp
*** Power to Weight Ratio = 5.39

MORAL TO THE STORY:

Get a Z06 up to 580 hp at the flywheel (not difficult), and you a car that is just as fast, if not faster, than the ZR1; that is naturally aspirated, and you save about 40K in the process…

Z06 by far is the meanest car on the road today... IMHO...

I'm afraid you've made a rather simplistic analysis here.

There is much more to the comparison than wt/peak HP.

Don't want to start flaming here, but you have left a lot out.

RoatanMan

Did you see the part where it says "just for fun"...? I know that I left a lot out, but from a bird’s eye of power vs. weight, this is a close analysis...

zhopper05

How about a package like the one I have - 630HP; that's a ratio of 4.96 at a cost of about $10,000.

UTVOL06

Both good illustrations, but the one main advantage the ZR1 has is near peak torque at low rpms due to the supercharger setup.

I would have prefered GM to take the C6 Z06 platform and just made the car lighter and with better suspension, brakes, tires, wheels etc. No HP bump would be needed.

There is a graph of the ZR1's HP curve over top of the Z06's HP curve and I can tell you that 75hp in the Z06 isn't going to be enough.

3350 is a little conservative. That's what it will weigh completly dry. Add 150lbs of fuel and water for cooling your almost 3500lbs!

TM-Z06

Wait til you add headers, CAI and tune to the ZR1. Or better yet, smaller pulley. You can believe the General will leave a lot on the table with these cars. Not to take anything away from the Z06.....it's still the car that others are trying to measure up to.

RoatanMan

Awesome!

Slow Vette

thats because even though the Z06 isn't the top car in the corvette lineup, its still a car that has *****, i mean, a car eith 400rwtq at 3k rpms ain't no pushover

RoatanMan

Good luck keeping that car on the road... Spin city! A little over the top ya think...

C5Lion

That is not true. All the weights are quoted from GM with all fluids in the car. This is what Porcshe and Ferrari like to do. The engineer I spoke with from GM at the track event a few weeks ago said that the base car will probably be within 100 lbs of the Z06. The fully loaded car will probably be the number we have all seen.

BLU-BY-U

thats why that zr1 will have a 2.29 1st gear. talk about steep! I think my '02Z had a 2.09 2nd gear

Don't forget a pulley swap on ZR1 is very easy mod for more HP.

Not true, curb weight includes all fluids and a full tank of fuel.

Point is, the Z with a few bolt-ons is a much better bang-for-the-buck supercar than the ZR1 will be. The comparison between the cars stated in the post, say in a 0-120mph run, I imagine would be very close. JMHO.

Jaxian

Since this is for fun, take a C5 Z, only 3030lbs, get an STS or ATI kit for 7k, 6-7psi, 600rwhp for a ratio of 5.05. It's the same suspension just with different calibrations. Plus your total cost would come out 30,000 bucks cheaper than a new C6 Z06. Of course it wouldn't be the total package a new C6 ZO6 is, but then a C6 ZO6 isn't the total package a C6 ZR1 is. Kinda see where I'm going with this? I bet you could take a 71 Duster and put in 600hp and run nines all day with it for 12k and knock another 25k off that C5 Z price. Matter of fact I know you can, I did it!



Of course it leaves a lot to be desired in the 'all around package' area, but hey, it's all for fun right.

allegretto

First of all; I love your license plate!

Second, they allow you to drive that car in the Nuclear Weapons Free Zone of Santa Cruz?

Jaxian

Nope, I actually had to sell it to get my first vette. I think that a car like that would cause Santa Cruz to implode. I have finally figured out what the deal is here with vehicles. Loud and slow. All Harleys or jacked up 4x4s. And a modified car in Santa Cruz means you put stickers on the back. hehe. btw points for getting the license plate, if I had a nickel for every person who said "two the win", whats that mean?../sigh. And yes I get much hate stares for the LG Pro's and B&B Bullets on my vette here from the granola's. College girls seem to like it though, and I am still young and single. Always a good side.

This is the EXACT same argument that people were making right here on this forum when the Z06 was introduced and compared with the Z51. But yet, everybody went out and bought one.
