550hp ZR-1 vs 550hp Z06

1. You are most liiiiiiikely Racing in MEXICO

2. i have a Z but im a Vette lover at heart, that's a mild cam z06, this is not the HCI Zs that are doing over 600 to the wheels, would've of been a much different story but he should've edged out the ZR1 with no problem having less weight and a better powerband. bad shifting on Z0 owner.

3. Dead nuts even

4. im a big chevy fan and i thought these came with 638 hp. maybe i am blind or just dont remember correctly but im pretty sure its not 550hp.

5. The first race he was the correct gear ..then he started in 3rd at 60 mph the z06 should be in 2nd and with HCI the hp should be in 700 fly 600 wheel ..

6. What about a higher rear end differential gear ratio's – say 4.10 or 4.25 gears

   Would do it

7. It amazes me how many of you know jack shit and just write the stupidest things on here.Dont you realize people read what you write and you look so stupid.

8. Zo6 just needed a duel clutch and some anti-roll bars. Would then make the difference noticeable.

9. Very impressed with that ZR1 hanging like that…I was sure the Z06 would slowly pull away with more peak power and less weight…Not to mention a powerband tailored for a high speed roll like the one in the vid.  Great vid.

10. nicetry64, 505 is a bout a 20% drive train loss…. 15% loss would equate to about 540rwhp.  Many are getting 530-540 depending on dyno conditions, which is on target.

11. 638 hp for zr1

12. @nicetry64 The day a stock supercharged 638hp ZR1 can only put down 505 RWHP, figuring in with drivetrain loss, is simply the day my shit turns purple & smells like rainbow sherbet. 550 RWHP out of a ZR1 is pretty much dead on. It's not like a truck; in which looses upwards of 120hp+ from the crank to the rear wheels…

13. Thats a nice race forreal!!!!

14. That was a good race

15. 88 gt 302 220 hp buddy.

16. Zr-1s have 638 bhp

17. lol @ people not knowing the difference between crank horsepower and wheel horsepower

18. racing with the window down stupid

19. LS7 is the most powerful N/A engine ever built by an American company.

20. nonono he said it makes 638 hp TO the camshaft… The camshaft makes an additional 500hp! lol

21. That was a good race

22. I want a 638hp camshaft for my Z06!!!

23. I could swear a zr1 has more than 550hp

24. what size tires was in the back of that is z06 ?

25. Nice Runs, I love to see N/A cars hang with FI 🙂
