Since we are starting to get some data on the ZR1. There was one recent thread with the ZR1 having 548RWHP & 53x RWTQ.

How much RWHP/RWTQ would a Z06 need to beat a ZR1 performance?


The ZR1 is an amazing car and you can't really compare it to the Z06 since there are so many upgrades but from a performance aspect what do you guys think?

EVILNESS

Mine made 565rwhp and went 11.0@133 from the gm said the zr1 will go 11.4@131 so i think anywhere above my power level should do it considering the heft of our cars vs the zr1...

530/500 will be enough to beat a ZR1. You don't need as much power because of the weight difference. That is until you get past 160 and you get left behind regardless of your power levels (almost)

Right, gearing in the ZR-1 is a big factor when considering if you want to beat one.

However, weight is important at well, and if all things considered, pound for pound and at equal power levels... a z06 SHOULD be in front though I find it unlikely with all the extra torque the ZR-1 puts out.

Look at those splits... 548hp/530trq. NICE!! Tires will hate you, but nice!

add a 100 shot of nos. my car bonestock made 460/435, so it should make 560/535 on the juice and be lighter.

That will definately work......

I think where your car is right now you should have no problems with a stocker. Then again...Its what happens when they put on a exhaust, intake, and a tune....not to mention if they boost more....then well...you know what you have to do....

Curb weight, Z06, lbs. (kg) -- -- 3164 (1435)
Curb weight, ZR1, lbs. (kg) -- -- 3350 (1520)

Bills Z06

Interesting thread, but remember, HP and torque are nothing without a good driver!

gerbie28

driver makes all the difference!!!!!!! Put Ranger against sum new driver in a ZR1 and he'll leave im scatching his head after the 1320!!

I think 540-550RWHP will get the job done

Hey H

I think are you asking in a drag race right? Because in top end or around a track that would be a different comparison.

My Cam and header Z06 put down 530rwhp and 500 ft lbs and on the drag strip ran a 10:9 @ 130.97 on bald stock RF's and I think that the ZR-1 with a good driver could eclipse that number easily so I'm thinking you'd need about 550 -570 at the rear wheels at least to be a competitor IMO. Remember what GM's numbers were on the Z06! 11.7 if I'm correct. GM is saying what 11.2. on the ZR-1 so you know that numbers is going way down with a good driver.

Yours has to be right there in my opinion but you know what it is like to drive as a daily driver and from what Mike - Short Throw said about the ZR-1 it drives like a dream.

I'm getting one but I'm waiting until the prices gets down to at least MSRP or less.

Hey you have 2 great toys to play with anyway

Talk to you soon

I don't think this is right. The ZR1 will have a much higher AVG HP.
I'm thinking it will take more NA power to beat it.

Vindication

people are still talking about that guy.....

My LS7 build put down 571/528 on the dyno at 5,500 ft elevation on friday ( uncorrected for Barometric pressure). At Road America, I was running down ZR-1's on both straights and got pass by's on a regular basis. No turbo, No supercharger = no heatsoak! N/A all tHE way!!

RoatanMan

My car runs about 570rwhp and is 3114 lbs (with Coil Overs)... So are you saying that I will walk a ZR1...

805Z06

Nice numbers rud...Your slowly catching up

160 MPH is more than enough for me. Just need from 60-150MPH would keep me happy.

Good thing I hooked up my differential.

Nice. That should do it.

As long as it can take a stocker I will be happy.





In the clear

Hey F!

No drag comparison for me. I suck at that. I will leave that to you guys. I just need a good highway roll style or enough power for the road racing track

TLK 2U LTR

I think so. Just looking for a stock Zr1 donor to find out

bowtiguy

all depends, did the drivers of the ZR1's I passed have their foot all the way into it? Exit speeds out of turn #14 and #5 at RA have a lot to do with it but the ZR1 actually has an advantage over me in that department with the new wider tires and better suspension than my current coil overs...not to mention those damn brakes.

This is exactly what happened to me at Day 1 when Tom Wallace passed me in my 1st session. I'd loose him on the straights but I couldn't shake him around 70% of the track and I had to let him go. By the second day and a bit more coaching on proper lines he got to return the favor.

Now a heads up drag race...that I don't know. I don't have a good comparison as I ran the car here in Denver yesterday and at 5,300+ elevation I squeezed out an 11.61 at 120mph with 1.98 60' not sure how that compares to a ZR1 at the same track but I ran a full second slower there in my LT1 B4C Z28 than I did back in Illinois at 1,000ft elevation

I agree we need a ZR1 donor car...in due time.

ZR-1 will have the advantage on the top end due to it's massive torque and broader powerband (twin screw supercharge does that for you). Plus it's gearing is far superior to the C6Zs for high speed acceleration.

A modded Z06 might give it a run to 150ish, but from 150 and beyond the ZR1s gearing will take over. Check out that video of them "testing" the first european one. The high end acceleration is astounding.

Watch videos of C6Zs racing modded M6s... the C6 is ahead until they hit 4th gear... the Bimmer's 6th gear (has 7) is it's 1:1 ratio so it's in 1:1 up to 180ish mph and that's where it pulls on the C6Z.

At the end of the day anything can be modded to beat anything.

greekc6

man i hope someone around me gets a zr1 to see how id do against one.

AU N EGL

Yah right.

Have you seen a ZR1 accelerate away from you from 40 to 150 mph?

I have. need more then just HP, Lots and lots of low end torque ( massive low end torque) plus aerodynamic body parts.

Zr1s may not be as fast as ppl think in the 1/4 or zero to 60 do the tall first gear 2.29, but 60 and above it is a rocket ship
