10.71 130.32 -- New Record Pass by Bone-Stock C6 Z06 on Drag Radials
 
A small group of the Corvette faithful gathered at Maryland International Raceway at Budds Creek yesterday, Sunday, December 11, to have some fun in the cool fall Maryland air. Racers from Florida, New Jersey, Virginia, and West Virginia made the trek. The lure was running in excellent conditions in a relaxed atmosphere on a racing surface prepared and tended to throughout the day by Royce Miller, owner of MIR. Mr. Miller is a hands-on owner whose work at this track is his full-time endeavor. That fact most explains the consistency MIR delivers and the hospitality its staff shows to all rentals customers.

The other participants will post (or not) their own results.

A few crew-members graciously took active roles in helping crew other cars and tending the water box/burnout area. That allowed drivers to focus on driving tasks. Joely volunteered to shoot video of some passes and Chris brought his nearly three-year-old son to stoke interest in this next-gen racer.

Sunday was my fourth track outing in the past month, after a one-year hiatus during which my car remained un-driven seven months. Started out rusty in mid-Nov and got back to full form after 20 or so runs down the 1320.

The shifting came back quickly, facilitated by endless garage drills. But launching the Z06 on Hoosiers required embedding in muscle memory a different approach than on the BFG 315.35.17s I’d run since 2006. The Hoosier’s soft tread compound requires 400-600 (or more) higher rpm at the hit of the clutch and a 20-40% faster throttle squeeze to WOT. Done right, the clutch is induced to slip on its own, but locks up quickly, keeping the car’s nose up from clutch-hit to the 1-2 shift. It’s the nose drop that wastes irretrievable tenths in the 60-330 incremental, thereby leaving ET on the table.

My best pass of the day was 10.71 at 130.32. The 660’ trap was 103.59. It reflects good but not perfect driving. As other drivers have shown, the Hoosiers can support a better 60’ than this 1.60. A 1.55 or 1.56 on this pass would have shed enough at the 330’ to bring the car to what would likely be its lower limit bone-stock (on DRs) of mid 10.60s. Don’t know who will do it eventually, but someone probably will.

The breakdown

60'................1.604
330'..............4.544
660'..............6.936
660’ mph..103.59
1000'.............8.981
1320'...........10.715
1320’ mph..130.32

The 330’ to 1320’ incremental was 6.17.

Weather conditions: Cool day, full sun, high barometer, average humidity; track surface mid-50s F. Air temp on racing surface mid-40s F. Slight intermittent head wind of 1-3 mph. (That means—no tailwind). I collected DA throughout the day in the shade but haven’t yet downloaded the numbers from my Kestrel weather station.



Thanks to the other participants and crews and friends for a fall day to remember. Until next time….

We should have video footage of this pass. When editing is complete, we’ll post it.

Incredable, Ranger !!!!!!! :thumbs: Sounds like a flury of fast runs and records came out of this track rental. I even did a trip planner to see how far away MIR is from my home, but alas, it's a wee bit too far for a long weekend roadtrip :rofl:

Congrats again on reseting the record !!!! These are truly incredable machines :rock:

whiplash306 12-12-2011 11:41 AM

UNBELIEVABLE Ranger!!! I certainly wish you lived closer as I'd toss you the keys to my BONE STOCK Z just to see what she's capable of...! Ha! Way to be a beacon for the Vette community! You ready for the C7?!?! :-)

Everett Ogilvie 12-12-2011 11:43 AM

Good to hear you are back in the saddle John, and congrats on the awesome passes! Good to hear from you again on the forum. :thumbs:

timber wolf 12-12-2011 11:50 AM

You make us proud!

D-Rod 12-12-2011 12:14 PM

It was an honor to witness sir! Thank you for all your advice for my passes. You are truely a class act.

Fartpipe 12-12-2011 12:28 PM

Congrats on a great pass Ranger. I'm not sure who was more shocked when that lit up on the board but fantastic doesnt even describe it. Maybe Supercalifragilisticexpialidocious?

screaminchevy 12-12-2011 12:32 PM

130 trap speed seems CRAZY to me on a stock Z!! was there any weight taken out of the car, just curious? very awesome run! i'm encouraged to read your feedback on the hoosiers. i've had a tough time launching on these as it seems there is less room for error in order to excape the nose drop. I'll be able to cut a good 60ft on mine eventually as i get some practice. your post confirms i'm not getting into the throttle quick enough.

Kyle Lemish 12-12-2011 12:39 PM

Congrats RANGER! Glad I was there to see it! Thanks for putting it all together....Another perfect day at MIR!

paisa427 12-12-2011 12:46 PM

Congrats ranger! I envy you guys up in the north east and the crazy ammounts of -DA you guys get!

Joe_G 12-12-2011 01:04 PM

Congrats - once again, you set the bar not only for performance but as an author with your informative and interesting accounts. Can't wait to see the video which are equally well done.

I have also found exactly as you - when you hit a good launch, the front end rises and never goes down. I like to say it feels like pulling a wheelie...and it's a great feeling, like hitting a golf ball 300 yards right down the middle (I'm guessing that must feel good:lol:).

I don't suppose I could convince you to post up a screen shot of the HP Tuners scan? Much could be learned by informed forum members to see how you execute....as shown on the graphs.

Joe
p.s. I ran the trip calc as well...1014 miles, 16 hours. Hmmm.

svtgeoff 12-12-2011 01:19 PM

driver mod for sure...


very nice!

Prime Target 12-12-2011 01:45 PM

Great run Ranger. Glad to see you're back in the saddle. :thumbs:

Undy 12-12-2011 01:57 PM

It sure helps when you have a DA like you're running at the bottom of the Marianas Trench too. Good job Ranger!

Congrats John, wish I could have made it out.

Congrats Ranger.

I enjoy your posts, and respect your driving capability.

Well done. Nice Christmas present to yourself.

timmyZ06 12-12-2011 04:18 PM

damn incredilble fast for a stock car, way to go ranger!

TAILWAG 12-12-2011 04:30 PM

speechless....

RichieRichZ06 12-12-2011 04:43 PM

Congrats buddy. As always, you demonstrate that prefect practice makes for perfect (or very close to it) runs.

:cheers: RICH
