200 mph
 

Has anyone here been 200 MPH in a ZO6? :D

yes

Thanks :cheers:

Did your car feel fairly stable?

yes

Thanks :thumbs:

Do you have any idea the distance required to accelerate to this speed?

yes, and it was stable.

Less than 2 miles from a stop.

Thanks, I have around 530 at the rear wheels. Are you stock or modded?

Stock. I've only been 197, but that was in a standing start 1 1/2 mile trap speed event. 173 in the mile.

This year, the Mile and Magnum events are on the same day !!!

I'm going to try and make it this year.

You should have a good run with the upgrades. :thumbs: You may break 200 in the Magnum, if you have the safety equipment to Tech for that.

I'm told they'll issue a 2 MPH buffer....I'd just like to have an official 200 MPH certificate. And, the current setup would definetly sail thru 200 in the Magnum......I'll lay off the throttle once I hit the number and stay within the legal and safety guidelines. I was impressed when you ran the number you did last year, given the weather conditions :thumbs:

They give a 5 MPH buffer in the classes. Check the rules for safety equipment. It is likely that you either have what's OK to Tech at 170 (+5) or Tech to 200 (+5). See: http://www.mojavemile.com/index.php?...d=10&Itemid=11

Basically to tech 200 you will need to do a mile run right near 150 if you've never run a similar event before, then they'll upgrade your driver classification for the next run in the 170 range then upgrade further.

For Tech 200 the driver will need a full race suit and arm restraints, helmet, gloves, etc. and the car will need Y or (Y) rated tires and at least a 5-pt harness. They Tech C6's for 200 with the standard roof (roll bar not required). I have a harness bar, 5-pt harness and full SCCA race gear including HANS.

PM me if you want more info, Victor.

I lost control at 175 and drifted...I saved it:woohoo:

It scared me lol

I had some lift occurring in a fender wheel, which is why this happened...

I talked to them earlier this year, but I'll PM you later on your experience. you going again this year ?

Sorry for thread jack, OP.
I think the Mohave Magnum event is the ONLY event where a stock Z06 has any chance of of touching the 200 MPH....legally.

Why did you have lift? I've ran mine with stock aero over 175 dozens of times and the car is solid.

I'm probably done with the MM until I make mods to the car to go faster and that will probably be a while. The 196.5 was about all I could expect from a stock Z06 and the 173 mile at 3000'DA was about as good as I'd expect stock, also.

Dave what did your speedo read to get 197 trap?

Yes, but I have Katech motor and modified aero!

I think the HUD indicated 198 right after I went thru the traps at official 196.5, measured for the 132' ending at the 1 1/2 mile mark. I was running nearly new M PSS in the stock 325/30-19 size and 34 PSI cold.

I don't normally expect the HUD to be that accurate as it usually 1 MPH high at 70 MPH indicated; the speedo is another 1 MPH off at that speed. Maybe there is some tire growth at the high trap speeds although the DIC was indicating 141.3 MPH average for a true 140 in the Silver State Challenge event. Now that the tires are worn I expect more of a variance.

I got an odometer reading of 91.3 miles over the 90.0 mile Silver State Challenge course with the nearly new PSS and got 88.8 miles indicated over that same distance with the somewhat worn Nitto NT-05's in 335/30-19 size.

For the Silver State, I drive up to Ely, NV in the reverse direction of the course and calibrate the odometer the day before the event with the tires I'll run, just to get a better idea how far off the odo and likely DIC average speeds are to help me get the car close to my target average speed in the event. In the last two events I got 2nd places with variances of 0.19 and 0.26 seconds over the 90 mile route, using the in-car data, a stopwatch and the mile markers (they go by fast at 140-160 MPH.

OP, I hope this is all of interest to you and not a thread hijack.

Thanks all and I am enjoying the conversation. 173 sounds pretty impressive in the standing mile. :thumbs:

I think the tires concern me most at those speeds...

Well the Michelin PSS are great tires with excellent grip, a (Y) speed rating and are XL load rated. They keep the runway as clean as it is reasonably possible to do and they have the safety equipment there. You are responsible for the maintenance and upkeep of your car (or a trusted mechanic is).

After that it is a personal decision as to what risk you are willing to accept. I was very comfortable in that environment and the stock Z06 was an amazingly competent platform, stable right up to top speed. It's kind of neat covering the last half-mile in 9 seconds (in the `1 1/2 mile event).

pppppttt

did the double ton on the way to the store today.

really.

Mine is stable at that speed. Going 180+ threw a corner hitting bumps over a bridge is a different story

I have an almost new set of y rated tires on the car, I am however in Tenn. so the west coast is too far for me. I did not know about the 1 1/2 mile events. I wonder if anyone has those events anywhere around here?

:cheers:

I have a road in mind, other friends have went in the 180's there, safest place we have found so far. :willy:

There's a half mile event in North Ga, September 14th and 15th.... It's not 1.5 miles, but it's still half mile drag racing on an airport. I'll be there both days

Stock Z06 should be in the 150-155 MPH range in the 1/2. I did my 4-5 shift at 162 at about 5/8 mile

Not at 3k elevation... I did it last year and ran 151 over and over. Intake, exhaust, and tune is all I had.

All my runs at 1 mile and 1 1/2 mile were at 3000' DA or more, actual elevation was 2738' and hitting 162-164 at about the 5/8 mile point - stock Z06.

Your 151 seems consistent with my guess of 150-155, doesn't it?
