Complete rules here: http://www.mojavemile.com/index.php?...d=10&Itemid=11

You do need to work your way up thru the speed classes, 170-190-220-240.

Corvettes and some of the exotics are lucky in that Mojave considers the B-piller hoop to be strong enough so a roll cage is not required until above 220. Mustangs, Porsche 911s, Chargers need it for over 190, but check the rules.

For my 09Z with HCI, essentially the car safety gear for tech at 220 was (Y) tires with reasonable tread and less than 5 years old, Harness bar and 5-point SFI rated harness and all the general stuff in good mechanical condition with no fluid leaks, loose body parts, etc.

The personal safety gear is more extensive, for 220 class you need current Snell SA rated close faced helmet, SFI rated head sock, gloves, shoes, socks, wrist restraints and fire suit (check rules for the SFI rating requirements. In addition, a HANS-type device is required.

For the 170 class, very little is required, for the 190 more personal gear and then 220 it is extensive..

They do allow same day upgrades as long as the car and driver equipment meet the next higher class. I don't remember the specifics, but as an example, if you ran 165 in the 170 class and did not run afoul of any rules, then you could go back to tech (on sight) and they would upgrade you to the 190 class. Then if you made a pass at 180-190 but not over, you could go back to tech and get upgraded to the 220 class. If you do a breakout of your class, then they will talk to you and probably require a class legal run before upgrading.

If that was the plan you wanted to go with, you would probably want to e-mail the MKM administration and discuss your plans and their expectation. The entry fee is significant, but you are making the runs in a safe environment.

i cant find any info on the actual runs. is it just a standing mile. or do you get a run up to it?
my research shows that a stock C6 Z06 is capable of 200 MPH, it just requires about 3 miles to do so.
im just cam and headers basically. heads are stock but fixed and decked .020 everything else is RR stuff. which is why i was really suprised you could do 200 in 1 mile. again unless there is a run up.

may i ask what entry fee is?

how carried away to people get away with aero and blue tape? are people removing spoilers, taping up grills and openings etc? ie minimizing drag?

huge thanks. very interested in this. especially since your requires WAY less than BBORR ie cage required.

i also looked up texas mile as its way closer, but again couldnt find any info on the actual runs either, ie standing mile or run up.

Navy Blue 210

The Mojave Magnum is 1 + 1/2 Miles in Length. Standing Start.

STANG KILLA SS

thanks! ok 1.5 mile standing start. that explains alot.

came across this vid by luck. but he wasnt able to get anywhere near your mph.
thoughts?

Stock ZR1 is giving up roughly 40-60 RWHP to a "600 RWHP" N/A Z06
Additionally, you don't know the temp, DA, wind, etc. the day the ZR1 ran.

AzDave47

... and the C6 ZR1 would be 250#+ heavier. The day before a C7Z with unknown to me mods (clearly not stock) ran 201.4. Thread here: https://www.corvetteforum.com/forums...ort-video.html

A C6 GS with SC and dyno'd at 686 rwhp ran 202.0 same day as me with "only" 180 MPH 1 mile speed versus my 187. He used my street 325/30-19 PSS as his were suffering from the death wobble and he cut the run short after the mile on his tires.

Dave, they've posted the results from your event on the website

Six 200 MPH cars for the weekend, three "big time" cars in the AU (266 MPH " '69 Camaro" - Big Red) and AA classes (236 MPH NASCAR Charger) and '15 Helcat (231 MPH, lots of work) and then three of us Forum members in the AB class. Chuck at 202.0 posted in this thread (ran his two 200 MPH passes on my street PSS, SC C6GS at 686 rwhp), Joel at 201.4 has his own thread on the C7Z forum (FULL bolt ons, CPR 2.3 upper and Redline 15% lower pulleys, B&B full Exhaust included long tubes...
Ryne at CMS did give it the latest tune once I added the 103 Katech TB!!), and my lonely N/A HCI 09Z.

A lot of haulin' motorcycles!

Any idea what was up with the '98 Supra? Go to a 1.5 mile run area and only top out at 79 mph?!??

AzDave47

There were several cars like that that only ron for the 1-mile traps. He did better in the mile than the 1 1/2 mile.

The Studebaker Avanti did 199 in the mile but much less in the 1 1/2 mile. The 1-mile traps were listed in order after the final Magnum page at the link above.

Driver's choice I guess.

Congratulations on the 200MPH Club!
I've been following your build closely, it looks like a great template.
We only have 91 here as well, but I'm OK mixing 100 UL or using octane booster for 93.
Curious about the driveability on the 501 cam. Will it cruise 6th gear/65mph happily?
Thanks!

AzDave47

Tune for 91, run 93 or add 100 to get it into the 94 range or octane booster, for safety preventative re detonation. You won't get more power. My WCCH heads are shaved.030, 91 tune and the most timing it will take is 19* advance.

This is my first cam'd street car. I wanted to break 200 at the Magnum so the build dictated what I would get. I do have some surging and the car is not a parking lot car any more, 12 MPH min. in 1st, 18 in 2nd. I just got back from a 100 mile drive today. some of it was 55-70 in 6th gear. It is fine going up hill with throttle, but has some surge under light or no throttle.

Some people don't want any surge. If so then the K501 or similar is not for them. I liked the drivability of the stock Z very much, couldn't believe it would drive smoothly at 30 MPH in 5th gear. Mine is not that car any more, but I picked up 14 MPH in the 1 mile trap ( now 187+) with 4300' DA) and got in those two 200+ runs, so I am happy that I did that and accept the minor surge as tradeoff.

Video of my 201.2 MPH run posted at our local Corvette club website, may take a few seconds to load, go full screen as video is good quality:

Thanks, Tom, for doing the video editing

That is pretty Awesome Dave.

tommyc6z06

Awesome!! Just wondering about the audio...are you lifting and feathering above the 1/2 mile and does that upset the car? or is the sound cutting a little?

AzDave47

My GoPro Hero4 is in it's mounting case and it doesn't pick up audio that well all the time. It is just audio cutting out, good observation. Foot flat on the accelerator pedal after 1st gear except for shifts. My shifts were at about 7000 RPM on 1-2, 2-3 and 3-4. I ran it as close to the 7300 FSO as I could in 4th to take advantage of the gearing as acceleration moderates quite a bit after the 4-5 shift. Other than 1st gear wheel spin (can't warm the tires on the airport property), the car was stable on all 4 runs.

Is there a method to the madness with the windows? Do you start with them halfway down and then have to put them up or something?

Nice run and congrats on 200 mph! Curious how fast you think these cars will go if you had enough space? Racing cars of years past used to have fairly high top speeds with
less power. Do you think they're 220 mile per hour cars with enough space and proper gearing?

AzDave47

Window, I realized it was down on the starting line so did the "one touch up - not", then realized at about 150 MPH it was only 1/3rd up, so put it up the rest of the way - good catch.
I think I trapped about 6400 with a power peak of 6700, so with 4 miles or so might get up to 208-210. It may do a little better with the C6 ZR1 tranny gears and the .67 6th. The racing cars of the late 60's into the 70's may not have had much more power but had only 60% of the weight in LeMans trim. I don't know what their overall drag was. The cd probably wasn't any better but less frontal area which would have been a big factor..

Racingswh

That's funny. I was thinking you had figured out some pressure equalization advantage. Reminds me of being in the middle of a quick lap and having nannies "magically" come back on and fumbling for the button to turn them off again. Always something.

You're right about the weight. They would have gotten up to speed faster. Mulsanne, even chicane free, isn't that long and they were still seeing some pretty serious speeds. They did have entry speed on their side as you are reaching 200 from a standstill which is pretty incredible when you think about it.

Great run and the car sounds fantastic too!!
