dont worry guys i will get you all a video asap of me with my cammed bolt-on 550 rwhp z06 vs zr1... You can trust me that it will be a completely different outcome.... call me cocky I guess... and 55 - 60 roll in 2nd is perfect! thats around 4600 to 5100 perfect for my cam. I ran 11.10 at 130 mph before the cam and tune with 470 rwhp on the stock runflats! I think with 80 more whp its a deep ten second car now. I would even put a couple bucks on me hangin with a header only zr1.... my z06 weighs 3020 lbs thats like a hefty passenger less than a zr1 haha not sure what zr1 weighs but am guessing 3250 somebody chime in if i am wrong... I think it would be a race between a bolt on z06 vs zr1 but it shouldnt be close with a cam bolt-on z06... thats a mid to low 10 sec car vs a low 11 sec car... I will stop talking now and just prove it to everyone. video will come just be patient.
ps. I do love zr1s and would give my left *** for one!
Great to hear, i am sure the outcome will be as we both know, but no harm in having the proof. I also agree a stock Z with a good tune and CAI, provided it has a good baseline, will hold its own against the ZR1 till the end of our 4th gear. When do you think you will have that video?
phatbeatnut, you have nothing to prove to us. A 550 rwhp Z06 will beat a stock ZR1 each and every time with EQUAL drivers. A 530 rwhp Z06 might do the same or be very close. Trust me when I tell you that Jorday knows cars and he knows what a camm'd/bolt on/tuned Z06 is capable off with the right driver behind the wheel.
I think what Jorday is trying to argue is that a STOCK Z06 is not going to touch a STOCK ZR1, which I whole heartedly agree with!! It will get raped, period.

Honestly, your entitled to your opinion and that is fine.... but you base this what, exactly?
"..not going to touch a stock ZR1" That would indicate an ass whooping and even the mag. articles with those pseudo-drivers haven proven that this idea is not the case.
Have you actually seen this match-up... I have. I'm not saying that the z06 will be door to door but what I am saying is that the gap will be closer than some WANT TO ADMIT... just because it was 638hp that doesn't necessarily make it faster. Much like the 2008 viper, 100hp more hp and NOW is when the racing gets fun.
Honestly, your entitled to your opinion and that is fine.... but you base this what, exactly?
Based on the fact that I have owned 2 C6 Z06's (modded and not), driven a ZR1, ridden in a ZR1 up to 190 mph, and raced them all against plenty of cars.
From a dig and up to the 1/4, a stock Z06 might give a stock ZR1 a decent run. From a roll, the ZR1 would just run away.
You guys are making it way more complicated that it really is... ZR1 wins because of a fatter power curve and much better gearing for high speed running. After 4th gear the C6Z falls on it's face while it pulls 5th to 200+.
Look at the race vids on line of modded C6Zs running modded M6s. The C6s always walks the dog up until the end of 4th gear. Then the M6s 7-speed gearing takes over. It has a 1:1 gear all the way into the mid 180s.

Would walk away meaning you haven't really seem this happen, have you? I have... it didn't. Now, being fair, i did have a Kb intake+tune @ 465rwhp so again, a ZR1 should be in front but NOT walk away... i just don't see that happening. My car, comparatively speaking, was 1/2 infront of a stock before the traps.

Again... it's not that complicated.
you got it... but top of 4th is 164mph so anyone going beyond that is just trying to prove a point. Of course the ZR1 will pull harder up top... way up top. The gearing is perfect for that while the z06 at 170mph is a dog with a stock 5th gear.
But still, I believe the point is that until then, a ZR1 is not "destroy everything" fast compared to a z06. Sorry, its just not... the price would dictate that it is but again, IT ... IS .... NOT.
Okay, here is my personal experience after messing with four different ZR1’s vs. CZ06’s modded and stock at local private airport by hwy 380. We also did some runs in the city of Mexico in a state located between Indiana and Iowa. I’m a drag racer, the below results were based on drag races and rolling pulls. I will also say this, in a road-racing segment; I can see where the ZR1 would kill the C6Z because the ZR is so much smoother and easier to drive fast.
1) Stock vs. stock: ZR1 wins but it’s a close race. I mean, like two cars. But wait, after about 3 good blasts, the race is even! Oh yes…EVEN! What? How you asked? HEAT. I purposely watch the scan file and data-logged the runs and noticed that once those big ZR1’s got hot, they feel about 40 or so ponies weaker. The N/A C6Z was not as finicky as the ZR and begged for more; the C6Z’s also seemed to cool off faster.
2) Bolt-on C6Z vs. stock ZR1: it’s bye bye ZR1, the CZ6 beats it by roughly 3 cars. By bolt-ons I mean (CAI kit, tune and headers). Here is where I was a little shocked: once rolling and then pushing it, the C6Z jumps out and by 130 or so, the lead fattened up to about 3.5 to 4 cars! How could this be? Oh wait, the 200 or so lbs penalty and the blower heat issue again.
3) Bolt-on C6Z vs. Tuned ZR1: now the mighty ZR muscle comes out. All we did is added a Vette-Air scoop and tweaked the ECU; that baby woke up, especially on the hwy. Standing start (1/4 mile race), they were almost even; the ZR1 hold about a fender edge but with one other ZR1, the races were too close to call, even after switching drivers. One of the ZR1 owners who also owns an M6 was not so happy about his bone Z getting flogged and run down by a stock C6Z and decided to leave and promised to come back with more under the hood at later time. From a rolling punch the C6Z still manage to jump but this time the ZR1 came around at around 120 or so and then held a two car lead to about 150 or so…we ran out of room, the airport is only about 2.8 miles long. So if you think about it, the ZR1 made up about 4.5 cars from when was stock just by adding air and tweaking the ECU…. that’s impressive.
4) Bolt-on/cammed C6Z vs. Stock ZR1: fogetaboutit…it was ugly. The C6Z walks away in every category standing start, hwy speeds, rolling from 20mph, 40mph and above. However, at 130 an above, the ZR1 feels like a nice Lexus 460LS while the C6Z feels like a 4cyl Civic at 7,000rpms trying to catch a V6 Mustang…LOL. If you were to do the same mods to the ZR1, the C6Z would not even be in the same zip code.
5) Bolt-on/cammed C6Z vs. Tuned ZR1 with headers: the gap was a little closer in every way, but the C6Z came out on top; these were close, very close races. Maybe one ZR1 was stronger than the other once on the road.
My overall take: for the money, I take the C6Z. The performance gap is not enough for me to justify spending the extra bread. Now, if prices were some how closer, then I’ll take the ZR1 hands down. One of the ZR guys later came back for a pulley swap and boost jumped to almost 3psi, but after 3 back to back dyno pulls, the heat killed almost all the gains; even with the tune. These cars need some sort of water tank coolers like the Cobras where a bigger aluminum tank can be use with Ice inside.

I never disputed that a cam/bolt on Z06 would beat a ZR1. Actually, I am 100% certain that a cam/bolt on Z06 would beat a stock ZR1 each and everytime from any roll up to 160 with a good driver. BUT, your other results in your post are surprising, I must admit.
Without getting into the physics of it, tell me, if TQ wins roll on races, then:
Why does a stock ZR1 outrun a 1000 ft-lb of tq diesel truck from a roll?
Why does a stock C6 Z06 with 400 rwtq stomp a pre-08 Dodge Viper with 470 rwtq from a roll?
Why does a C6 Z06 with an intake and a tune only, making ~430 rwtq, run right with a 08 Viper that makes 500 rwtq from a roll?
Why does a Ferrari Enzo, a car that has more than 100 ft-lbs. LESS tq than a ZR1, trap several mph higher? (meaning, it would most probably win a roll on race)
Want me to keep going?
TQ DOES NOT win roll on races. It does, however, help out tremendously in a road course event where there is a lot of coming in and out of corners.
You post just proved to me your have spend most of your time magazine and internet racing than actually spending time racing.
Getting tired magazine racing with you clowns, so you'll have to excuse me if I let you wollow in your ignorance.
My only advice if your not willing to listen, is spend time at a race track, both strip and road racing, then maybe you'll wake up.

Thank you... you reinforced everything that I have been flamed for. For the price, the C6 Z06 is the better value performance wise unless we're talking about braking!
Still, it would seem that most just don't want understand or realize that in the real world, the ZR1 is not THAT MUCH FASTER than a Z06. Fantastic car but like you said, heat soak and weight are it disadvantage.
Now, a little benchracing here and this is just for fun!
Looking at these two videos, does the ZR1 look faster than a z06? Both video's were shot on an airstrip and motortrend was behind the wheel on both.
You post just proved to me your have spend most of your time magazine and internet racing than actually spending time racing..
Keep on telling yourself that torque wins roll on races. Make sure you preach that to the pre-school kids, not adults that understand racing. Otherwise, you will look like a fool.
You guys that keep referring to the ZR1's weight are a little delusional. It's only 200lb's guys. You only need about 20 extra horsepower to make up for this weight. The ZR1 has an extra 130. The rule states that for every hundred pounds, you need 10 horsepower. This formula is consistent for cars in the 11-15 second range.
The rule you are talking about does apply to 300 hp 3000 pound cars that run mid to high 13's but once you get to the low 11's in 3300 pound cars it takes closer to 40 or 50 hp to pick up a tenth or 2 in the 1/4 mile.

What you posted in your experiment is pretty much what I would of expected.
The rule you are talking about does apply to 300 hp 3000 pound cars that run mid to high 13's but once you get to the low 11's in 3300 pound cars it takes closer to 40 or 50 hp to pick up a tenth or 2 in the 1/4 mile.
That is more inline with what I seen locally. 20hp is practically nothing and if anything, you might a 1/4 car difference... that's it.

However, at 130 an above, the ZR1 feels like a nice Lexus 460LS while the C6Z feels like a 4cyl Civic at 7,000rpms trying to catch a V6 Mustang…LOL. If you were to do the same mods to the ZR1, the C6Z would not even be in the same zip code.
5) Bolt-on/cammed C6Z vs. Tuned ZR1 with headers: the gap was a little closer in every way, but the C6Z came out on top; these were close, very close races. Maybe one ZR1 was stronger than the other once on the road.
My overall take: for the money, I take the C6Z. The performance gap is not enough for me to justify spending the extra bread. Now, if prices were some how closer, then I’ll take the ZR1 hands down. One of the ZR guys later came back for a pulley swap and boost jumped to almost 3psi, but after 3 back to back dyno pulls, the heat killed almost all the gains; even with the tune. These cars need some sort of water tank coolers like the Cobras where a bigger aluminum tank can be use with Ice inside.
