POLL: For how many has LBA180?

[cward]

I seem to recall hitting 180+ quite a few times. So for the poll, MANY times.

Might add another option: 200+

I think there are several drivers that have done that in their Z's.

I just got back from the valley and my latest early morning run. I DID IT my new Personal record196 but Holy SH*t almost lost it on the shut down ended up do a 360 but stayed on the road. Excuse me but I think I sucked the seat up my butt and I gotta go remove it. I know I flat spotted the tires. on the way home felt like a centapeed witha wooden legg 99 thump. Man do things happen fast at that speed

Yes, at that speed things do happen very quickly. There are several things you can do to help you when attempting to go fast. One, and imo, is to have very good tires. I mean VERY good tires. There are only a few that are rated above 180 mph. I would suggest that if you are going to try going that fast, then get a set of them. Most of the drivers at ORR events that have had bad experiences had them occurr because of tire failure. Losing a tire above 180 is a bad thing. Two, put all the positive caster available into the steering to slow down the steering. Setup the suspension to lower the car as much as you can, especially in front. Put the slightest bit of toe-in front and rear. You do not want the car to have any toe-out. And some negative camber also. Not too much. Also, try to stiffen up the suspension so when you let off, the rearend does not want to come around. That means setup the car on the tight side, not loose. I don't know how fast you were going when the donut happened, but I do know that donuts above 100 mph will get the adrenalin(sp) flowing. 196 mph is very fast. Congratulations. You also might consider doing those runs by yourself. You do have good life insurance don't you. :-) I was asked by my wife to increase mine when I started high speed racing. I did as she asked.

thanx for the info on the car set-up . Tires I have the goodyear dg-3s ithink is what they are. tread is like a big V.. Are they ok or whats the best. i dont care if they wear out quick . whats the best street legal tire.? 18 s better? I have been thinking of doing coilovers. would that be the way to go? Can one get a reasonably priced set up to set thet front end. I don't need life Ins as I am single with no family. Am An EX ranger so I am a little nuts anyhow. But your right a smart guy would set the car up a little better. Also ntghinking the silver state race in one of the mph cat. might be fun too. SO new ? what would you all do / change for high speed runs? be thankfull for any advise. OH P.S. spunabout 90 3-360s and you are RIGHT you know your heart is pumping. Wheni got it stopped and got out . I just sat down ,serious shaken goin on

They have a "Y" service description and thus are rated up to 186mph when properly loaded/inflated.

I have seen Michelin provide speed rating data that indicated at a set of speeds what % of the max load the tire could take, and what additional pressure was needed. On some by the max speed rating, it could only take 95% of the max rated load, and required +5 psi additional pressure.

It might be worthwhile to contact Goodyear and find out what they recommend in regards to taking that tire to its top speed and beyond.

Holy Shiite indeed, Jon...glad you're still here, congrats!=D>

I don't know Curtis personally, but from reading everything on the forums about his high speed exploits in a Z I'd say he definately knows what he's talking about. After I meet some other obligations and commitments in my life, I'd like to do a little ORR and set my Z up to run up to 200...but 1 thing at a time.

Let's see if I can try to answer some of your questions. Those are pretty good tires if they do not have too many miles. Now with flat spots, you will have to replace anyway. Coil-overs are a good thing if you are going to try to go fast and turn too. I used DRM. 17's are OK. I switched to A-Molds because they looked better and are lighter than the saw-blades. Any good alinement shop with 4 wheel alignment equipment should be able to set up to your specs. Should be able to get it done for less than $100. All the ORR events have rules. Running is GS means you don't have to do much to your Z. Tech is 165 so Z will take that pretty easily. SS classes and Unlimited require much more safety equipment and are harder on the Z.

OK GUYS CURTIS EMAILED ME THE PHOTOS OF HIS ZR-1 IN THE BIG BEND OPEN ROAD CHALLENGE FOR ME TO POST HERE SO YOU ALL CAN SEE HOW HE SET UP THE Z FOR THE 201 BEST IN 2002. NOTICE HOW THE Z WAS MUCH LOWER BETWEEN THE 2000 VS THE 2002 RUNS. THIS IS WHAT CURTIS IS TALKING OF GETTING THE Z NICE AND LOW. HEY CURTIS WHAT IS ALL THE DUCT TAPE ABOUT? IS THERE A CONCERN ABOUT AIR GETTING IN THE FRONT AT THE PLATE AND TURN LIGHT OPENINGS? BTW HOW MUCH OF A BLUR DOES IT BECOME AT THOSE SPEEDS? I IMAGINE QUTE A "TUNNEL VISION" EFFECT HAPPENS AND TIME STANDS STILL FOR THOSE BREIF MOMENTS WHEN YOUR AT THE MAGIC 200 MARK----

HERE IS A LINK FOR THE "TOP GEAR" BUGATTI 253 MPH RUN --- ONLY $1,669,314.00 = 850,000 UK POUNDS SUCH A BARGIN---THINK I'LL ORDER ONE OR TWO!!! LOLOL WHAT PRICE GLORY----- 1,001 HP = 253 MPH

Yes...that's how I eventually want to get mine to squat down to keep the air from getting under there. 1st things 1st (P&P, pc, headers, etc) though.

I never get tired of reading Curtis postings about high speed runs in these cars
